Definitions

  • This invention pertains to a non-ferrous metal mold plug activation system and bleedout detection and plug off system, which stops the flow of metal during predetermined conditions, such as during the initial introduction of molten metal to the molds or in the event a bleedout is detected in the mold.
  • Metal ingots and billets are typically formed by a casting process, which utilizes a vertically oriented mold situated above a large casting pit beneath the floor level of the metal casting facility.
  • the lower component of the vertical casting mold is a starting block mounted on starting block pedestals.
  • the starting blocks are in their upward-most position and in the molds.
  • the starting block is slowly lowered at a pre-determined rate by a hydraulic or pneumatic cylinder or other device.
  • solidified non-ferrous metal or aluminum emerges from the bottom of the mold and ingots or billets are formed.
  • Figure 1 illustrates one example.
  • the vertical casting of aluminum generally occurs beneath the elevation level of the factory floor in a casting pit.
  • a caisson 3 Directly beneath the casting pit floor 1a is a caisson 3, in which the pneumatic or hydraulic cylinder barrel 2 for the hydraulic cylinder is placed.
  • the components of the lower portion of a typical vertical aluminum casting apparatus shown within a casting pit 1 and a caisson 3, are a hydraulic cylinder barrel 2, a ram 6, a mounting base housing 5, a platen 7 and a starting block base 8, all shown at elevations below the casting facility floor 4.
  • the mounting base housing 5 is mounted to the floor 1a of the casting pit 1, below which is the caisson 3.
  • the caisson 3 is defined by its side walls 3b and its floor 3a.
  • a typical mold table assembly 10 is also shown in Figure 1, which can be tilted as shown by hydraulic cylinder 11 pushing mold table tilt arm 10a such that it pivots about point 12 and thereby raises and rotates the main casting frame assembly, as shown in Figure 1.
  • mold table carriages which allow the mold table assemblies to be moved to and from the casting position above the casting pit.
  • Figure 1 further shows the platen 7 and starting block base 8 partially descended into the casting pit 1 with billet 13 being partially formed.
  • Billet 13 is on starting block 14, which is mounted on pedestal 15. While the term starting block is used for item 14, it should be noted that the terms bottom block and starting head are also used in the industry to refer to item 14, bottom block typically used when an ingot is being cast and starting head when a billet is being cast.
  • starting block base 8 in Figure 1 only shows one starting block 14 and pedestal 15, there are typically several of each mounted on each starting block base, which simultaneously cast billets, special shapes or ingots as the starting block is lowered during the casting process.
  • the lowering of the starting block base 8 is accomplished by metering the hydraulic fluid from the cylinder at a pre-determined rate, thereby lowering the ram 6 and consequently the starting blocks at a pre-determined and controlled rate.
  • the mold is controllably cooled during the process to assist in the solidification of the emerging ingots or billets, typically using water cooling means.
  • hot top technology generally includes a refractory system and molten metal trough system located on top of the mold table, whereas the conventional pour technology involves suspending or supporting the source of molten metal above the mold table and the utilization of down spouts or tubes and floats to maintain the level of molten metal in the molds while also providing molten metal to the molds.
  • the metal distribution system is also an important part of the casting system.
  • the hot top distribution trough sits atop the mold table while the conventional pouring trough is suspended above the mold table to distribute the molten metal to the molds.
  • Mold tables come in all sizes and configurations because there are numerous and differently sized and configured casting pits over which mold table are placed.
  • the needs and requirements for a mold table to fit a particular application therefore depends on numerous factors, some of which include the dimensions of the casting pit, the location(s) of the sources of water and the practices of the entity operating the pit.
  • the upper side of the typical mold table operatively connects to, or interacts with, the metal distribution system.
  • the typical mold table also operatively connects to the molds which it houses.
  • the molten metal is cooled in the mold and continuously emerges the lower end of the mold as the mold table is lowered.
  • the emerging billet, ingot or other configuration is intended to be sufficiently solidified such that it maintains its desired shape.
  • Conditions may develop during the casting process which cause the molten aluminum to pass through the mold without sufficiently solidifying, such that instead of solidified metal emerging, molten metal leaks through. This is referred to as bleedout or breakout and not only creates a very dangerous condition, but causes substantial economic loss due to the physical damage that results and the downtime to the production line.
  • thermocouple places a heat sensing device or thermocouple in the mold air cavity, and then calibrating the thermocouple such that it sends a signal to a controller when a pre-determined temperature is reached.
  • the temperature is pre-determined such that the signal is sent when a bleedout condition occurs.
  • the sensor typically sends a signal to an electronic controller, which reads and interprets the signal, and then transmits another signal to a mold plug activation device, thereby causing the mold plug to block the flow of metal to the mold.
  • Examples of problems with these prior systems are: they require the use of an electronic or other controller to receive the signal from the sensor, interpret the signal, and then send a second signal to the mold plug activator; they do not operate reliably in such a harsh, hot and corrosive environment; they depend on reliably receiving a readable electrical signal of some sort from the sensor, in the harsh environment; they depend on the reliability of the controller, its ability to receive and interpret the signal, and its ability to then transmit a second to the mold plug activator; and there is an unacceptably long period of time during which the first signal is received and interpreted, and the second signal is transmitted to the mold plug activator.
  • Prior art systems simply depend on too many factors and components which do not operate reliably enough in a harsh environment, as well as too many components.
  • the costs of the prior art systems are also higher than they need be, due to the number of components and the expense of attempting to provide protection for the components from the operating environment.
  • This invention accomplishes these objectives by providing a mold plug activation system wherein the sensor is preferably directly connected pneumatically, electrically, mechanically, or otherwise, to the mold plug activator. This invention preferably avoids the use of intermediate controllers between the sensor and the mold plug activator.
  • This invention further allows utilizes an activation system which may be placed in the normally closed position such that when power to the molds is lost, the metal flow stop devices move to block the continued flow of metal to the mold inlets.
  • This invention can also accomplish these objectives by providing a mold plug activation system wherein the sensor is sacrificed in the event of a mold bleedout, i.e. a disposable or sacrificial sensor, which is partially or wholly destroyed or sacrificed in the event of a bleedout.
  • a mold bleedout i.e. a disposable or sacrificial sensor
  • this invention provides a system which is simpler, more reliable and safer than all prior systems, and which should reduce the risk of injury to workers in casting facilities.
  • this invention applies to and can be utilized in connection with various types of metal pour technologies and configurations, including but not limited to both hot top technology and conventional pour technology. It is further to be understood that this invention may be used on horizontal or vertical casting devices.
  • the mold therefore must be able to receive molten metal from a source of molten metal, whatever the particular source type is, whether it be hot top pour technology or a conventional pour apparatus.
  • the mold cavities in the mold must therefore be oriented in fluid or molten metal receiving position relative to the source of molten metal.
  • metal flow stop device as used herein can be any one of a number of different devices. Examples of metal flow stop devices currently known are, without limitation, mold plugs and metal trough dams, rotatable trough dams, slide devices, and any others which stop the flow of molten metal to the mold inlet, as shown in the drawings and further described below and as known in the art.
  • metal flow cavity as used herein can be any one of a number of different cavities, conduits, or troughs. Examples of metal flow cavities as used herein and which are currently known are, without limitation: a mold inlet for receiving molten non-ferrous metal; or a trough or conduit configuration through which molten metal is supplied to a mold.
  • this invention also contemplates that the flow of metal to more than one mold can also be stopped by applying the metal flow stop device to a metal flow cavity which provides molten metal to more than one mold.
  • failure condition may mean any one of a number of conditions which are desired to be detected or monitored.
  • Example of failure conditions contemplated by this invention may be a mold bleedout or breakout condition, or an overheating condition in one or more pre-determined locations.
  • biasing force as used herein and as contemplated by this invention can be accomplished or achieved in any one of a number of different ways.
  • the term biasing force as used herein is intended broadly enough so that the force of gravity may be used as the biasing force, such that imparting a biasing force is meant to include using the weight of the metal flow stop device itself (or weights attached to it) as the biasing force, in addition to the many other ways that can be used to impart a force on the metal flow stop device.
  • increasing the biasing force it is meant herein and contemplated by this invention to include any device or method which serves to increase the biasing force on the metal flow stop device.
  • a balancing force as used herein and as contemplated by this invention can also be accomplished in any one of a number of different ways.
  • ways to achieve or impart a balancing force within the contemplation of this invention may be, without limitation: providing a pneumatic pressure opposing the biasing force; providing an overhead support such as the rope and pulley configuration, as more fully illustrated and described in reference to Figure 3; or even a rigid support member preventing the metal flow stop device from being moved into the metal flow cavity by the biasing force.
  • reducing the balancing force it is not intended to be limited to just reducing, but instead also may mean eliminating the balancing force.
  • the reduction or elimination of the balancing force allows the biasing force to move the metal flow stop device into a predetermined metal flow cavity, to effectively stop the flow of metal.
  • Increasing the biasing force or reducing the balancing force (or both) are directed to causing the metal flow stop device to be moved into the metal flow cavity, to stop the flow of metal to the blowout or other non-desirable condition.
  • a first example is the utilization of a pneumatic cylinder to facilitate the movement of the metal flow stop device into the metal flow cavity, which is schematically illustrated in Figure 2.
  • the metal flow cavity is not actually depicted, however, the metal flow stop device is mold plug 20 attached to mold plug stem 21.
  • a guided air cylinder 22 is provided wherein a source of compressed air is supplied through an airline 23 operatively connected to the guided air cylinder 22, as depicted in Figure 2.
  • the system may be configured so that either gravity or a second airline provides the biasing force on the metal flow stop device 20, which is connected to and moves with the air cylinder 22.
  • the air cylinder 22 is available through SMC Pneumatics, Inc., of Indianapolis, Indiana.
  • a compressed airline 23 is operatively connected or in fluid communication with the lower end of the air cylinder 22. This will be referred to as the balance air.
  • the balance air line is operatively connected to a source of compressed air and is also operatively connected to or in fluid communication with a sacrificial sensor line 24, which in this case is a polymer or plastic air line.
  • the sacrificial sensor line 24 is positioned in the vicinity below the mold inlet where the metal is supposed to be emerging in solidified form, i.e. in the mold air cavity.
  • the sacrificial sensor 24 is a polymer air line which encircles the solidified metal emerging from lower portion of the mold.
  • the molten metal flowing through the mold contacts the sacrificial sensor 24, and destroys the containment of the compressed air. This effectively reduces or eliminates the balancing force, which allows the biasing force to move the air cylinder downward, and which consequently moves the connected metal flow stop device into the metal flow cavity.
  • the term destroyed is used in reference to the sacrificial sensor, it is intended to be construed broadly such that the sacrificial sensor can be partially or wholly destroyed. This typically occurs to cause the reduction or elimination of the balancing force opposing the biasing force imparted on the metal flow stop device.
  • the guided air cylinder 22 allows or forces the metal flow stop device, in this case a mold plug 20, to move into the mold inlet.
  • Figure 2 illustrates the use of a cylinder lift valve 60, which in the pneumatic embodiment of this invention would be an air piloted cylinder lift valve 60.
  • the cylinder lift valve 60 shifts the application of pressure when activated, from below the cylinder to above it, thereby causing the metal flow stop device, i.e. the mold plug 20, to move toward and block the flow of metal.
  • FIG. 2 also shows flow control devices 25, which are flow control devices available through SMC Pneumatics, Inc. of Indianapolis, Indiana.
  • a plurality of metal flow stop devices may be placed in the normally closed position.
  • the mold plug 20 would be normally positioned within the mold inlet, and when the system is energized, the mold plug 20 would be removed from the metal inlet and thereby allow the flow of metal through the mold inlet.
  • the molten metal can be introduced in the conduit or trough system and distributed to positions near each mold inlet. Then once the mold troughs are sufficiently full of molten metal, the system may be activated, thereby simultaneously introducing the molten metal to each mold inlet.
  • this invention may be utilized in situations where there is a loss of electrical energy or power to the molds on a mold table during times when molten metal is still contained within the troughs or conduits (the molten metal delivery system). Since the metal flow stop devices are normally closed, the loss of power will cause the cylinder lift valve 60 to decrease the pneumatic pressure or balancing force, thereby causing the metal flow stop devices to stop the block the flow of metal when power is lost.
  • Figure 3 illustrates a second example, which is one of the simpler embodiments of the invention.
  • the metal flow cavity being blocked is the mold inlet for the affected mold and the metal flow stop device is a mold plug.
  • the metal flow stop device is a mold plug 20 attached to mold plug stem 21, and is suspended or supported above the metal flow cavity.
  • the force of gravity is utilized as the biasing force and the magnitude of the force is determined by selecting the weight desired for the metal flow stop device.
  • the balancing force in the second example is imparted by a supporter, which in the example shown may be a rope 29 or cable, and may be made of any one of a number of different material or combinations of materials, as will be appreciated by those skilled in the art.
  • the upper portion of the supporter is operatively connected to the mold plug stem 21, either directly or indirectly, and effectively suspends the metal flow stop device above the metal flow cavity.
  • the upper portion may be located vertically above the metal flow stop device, such as by a pulley structures 28.
  • the supporter lower portion 27 can be located in the vicinity of where the solidified metal emerges from the mold, which is generally below the mold inlet and within the mold air cavity, which is illustrated as item 37 in Figures 4 & 5 for example.
  • Part or all of the supporter lower portion 27 can be made of a material that will be destroyed by contact with molten metal, such as rope, organic material, polymers, or many other compositions.
  • the supporter lower portion 27 may be positioned in one or more locations, or all around the emerging solidified metal, to quickly detect a bleedout on any side of the emerging metal.
  • the molten metal When a bleedout condition is encountered, the molten metal would then contact the supporter lower portion 27 and destroy it, for example by burning an organic rope. The destruction of the supporter lower portion 27 would result in the elimination of the balancing force, and the biasing force would then cause the metal flow stop device to move into the desired metal flow cavity and block the flow of the molten metal to the mold wherein the bleedout occurred.
  • the supporter lower portion 27 would therefore operate as a sacrificial sensor.
  • the supporter lower portion 27 would then be the sacrificial sensor in that it would be appropriately positioned below the mold inlet such that when molten metal from a bleedout condition contacts the lower portion of the supporter (the sacrificial sensor), it would be destroyed.
  • the destruction of the supporter would reduce or eliminate the balancing force and allow gravity (as the biasing force) to cause the movement of the metal flow stop device into the metal flow cavity.
  • the supporter may be positioned in any one of a number of locations relative to the metal flow stop device, including above, below, or transverse.
  • Figure 4 is a cross sectional illustration of an embodiment of the invention wherein a metal trough dam 30 is the metal flow stop device, which moves into the metal trough 31 to block the flow of metal to the subject mold(s).
  • the metal trough 31 is typically refractory material.
  • Figure 4 illustrates a permeable graphite ring wall 62, through which a lubricant and a gas are permeated and which create an air gap between the emerging solidified metal 64 and the graphite ring wall 62.
  • the emerging solidified metal 64 can be any one of a number of shapes, including billets, ingots or any other special shapes.
  • Figure 4 also illustrates coolant outlets 66 from which water as the coolant is discharged to cool and provide the cooling for the solidification of the metal as it emerges into the mold outlet cavity.
  • the portion of the mold outlet cavity between the emerging solidified metal and the mold housing is referred to herein as the mold air cavity 37. It is in the mold air cavity 37 where the sacrificial sensor is most effectively placed to detect a bleedout condition.
  • Figure 4 also illustrates the mold inlet 32, the sacrificial sensor 33, which in this embodiment is the plastic air line as depicted in Figure 2, as item 24.
  • the sacrificial sensor 33 is shown positioned around the periphery below the lower portion of the mold inlet 32, which would surround the emerging solidified billet under normal operating conditions.
  • Figure 4 illustrates a typical casting mold 34 and related components, all of which are generally known by those skilled in the art.
  • Item 37 in the area below the mold inlet 32 represents the mold air cavity 37, in which there should be no molten metal during normal or desired operations.
  • the metal flow stop device is a metal trough dam 30.
  • an alternative way to force the metal flow stop device toward the metal flow cavity is to make the metal trough dam 30 relatively flat so that when it is aligned with the flow of metal in the trough, molten metal is allowed to flow by it and to the mold inlet 32.
