Definitions

  • This invention relates to motion control systems, e.g. for a single strand or multiple strand casting system and generally to horizontal continuous casting systems.
  • a supply of molten metal is provided to a tundish prior to the initiation of the casting process.
  • a starter bar having a cross-section corresponding generally to that of the to-be-formed casting is inserted into the casting mold.
  • a slide gate on the tundish is opened and the molten metal within the tundish flows out through the exit port into the casting mold and welds to the starter bar.
  • the drive motors then initiate the desired casting motion for the casting system and the process begins.
  • the motion of the casting which is forming within the casting mold comprises a series of motions in accordance with a predetermined motion profile.
  • the motion profile most commonly used includes a series of short forward mo­tions referred to as casting strokes.
  • each forward motion is followed by a short reverse motion.
  • a series of motion cycles occur, each of which includes a forward casting stroke followed by a brief reverse movement.
  • a motion control system and a single or multiple strand horizontal continuous caster having furnace means; molds and aftercoolers; and drive means driven by an electric motor, preferably a DC torque motor.
  • the motion control system comprises a closed loop control system operative upon an electric motor for each strand of the caster.
  • an encoder is coupled to the output shaft of the electric drive motor.
  • a sensor coupled to the encoder provides an output signal indicative of the rotational motion of the drive motor.
  • a computer control system receives information and produces a series of signals corresponding to the desired motion profile or motion cycle to be used in the casting process.
  • a detector system within the control loop responds to the encoder output and to a sample of the desired motion profile cam, and produces the appropriate output signal to be applied to the drive motor to achieve the desired motion.
  • the output signal is ampli­fied by a motor drive amplifier to a power level sufficient to operate the system's drive motor.
  • the computer system receives information and updates the process control dis­plays in real time on a velocity versus time profile of the drive motor.
  • the system based primarily on hardware, not software, gives real-time control and is extremely rapid and accurate.
  • a tundish and tundish car 1 having an interior insulated reservoir is provided having an exit port 2 usually near the bottom surface of the tundish.
  • a slide gate 3 is supported in proximity to the exit or discharge port of the tundish to permit the tundish to be opened or closed as needed.
  • a refractory material lines the interior of the tundish and protects the tundish structure against the molten metal supported therein.
  • One or more ceramic ele­ments or nozzles, not shown, are provided within the tundish discharge orifice to provide an appropriate interface to the remainder of the casting system.
  • the mold and aftercoolers includes a surrounding cooling system which provides for a substantial flow of coolant such as water about the exterior surfaces of the mold passage.
  • the mold is generally formed of copper or other metal having a high thermal conductivity.
  • a fluid control system is operative upon the casting mold to provide the necessary coolant flow in and about the exterior of the mold casting passage.
  • a series of support rollers 7 are ar­ranged in a generally linear path to support and provide a rolling surface for the casting as it exits from the casting mold.
  • One or more pullers with a DC torque motor 11 are operatively coupled to the emerging casting and provide the desired motion of the casting.
  • a cut-off torch 8 is 10-­cated downstream of the pullers which functions to cut the strands into proper lengths.
  • an en­coder 13 is connected to the shaft 12 of torque motor 11. This encoder is the beginning of the motion control system.
  • the primary duty of the motion control system is to precisely control the DC motor pullers in order to provide precise extraction and solidification of steel during cast­ing and to monitor and control all the hydraulic, pneumatic, and temperatures critical to proper casting conditions.
  • a preferred form of the motion control system of the present invention is gener­ally comprised of three AT type computers with an Intel 80386 architecture. In each of the AT computers are several "stand alone" single board computers dedicated to specific tasks. Each of the single board computers provides its own bus and external connections to the external components which interface to a controller card.
  • the three AT type computers are named according to their primary function -
  • the PCS computer preferably contains ultra-fast, high resolution (1280 x 1024) display controllers which receive information from the AT bus and update the process control displays in real time. These displays are nearly as fast as a real time oscilloscope and display velocity versus time profiles of each motor which is casting steel, i.e., one motor for each strand. This display is essential for monitoring the proper extraction and solidification of the steel during casting. Additionally, the display can be designed, as desired, to show -
  • the PCS computer receives its information from an interface board which latches all of the encoder edges in both directions which is attached to the motor shaft of the drive motor for the strand being cast.
  • the motor amplifier also provides a DC output proportional to the motor current. This is input to the interface board, and then converted to an actual motor torque display.
  • the system utilizes Start­up Cams. Thus, there can be as many as eight alloy banks of eight each which provide pre-programmed extraction and pause profiles used when first starting the cast.
  • a unique fea­ture of the system is the use of single board computers which provide dedicated control systems for very fast real­time control of a specific task.
  • the cam generation and touchscreen interface provide instantaneous regeneration of cam profiles during casting.
  • the digital process displays provide oscilloscope-type waveforms of velocity profiles as well as color text and bar graph information not available from an oscilloscope.
  • the PLC and data acquisition compu­ters provide all required elements for a complete system integral within the control system so that no additional equipment is required at plant installation.
  • a separate monitor displays line trends of thermo­couple and temperatures of casting molds, water temperatures of the coolers, and material handling equipment. This in­formation is received through a communications link with the other two AT type computers, TS1 and TS2.
  • the TS2 has one VGA (640 x 480 resolution) color display which has touchscreen capabilities so that when the graphic system display is touched, it provides control of all external system components such as pumps, solenoids, argon pressure in furnace, air pressures, water flow rates, furnace temperatures, utilities for specifying the type of equipment attached to the system, as well as the diameter of steel being produced, the specific density of the steel, and self-diagnostic routines in order to troubleshoot mainten­ance problems.
  • VGA 640 x 480 resolution
  • This computer also has single board computers for programmable logic controllers and data acquisition control­lers which act as stand-alone computers on a card and re­ceive information through a dual port RAM in order to inter­face to the host AT.
  • a printer is also attached to TS2 for run-time logging of all events and data during casting. All thermocouples, flow rates, and events such as solenoids, pumps, and casting motor information are stored as well as communicated to the other two computers in the system.
  • the TS1 is an important computer in the casting operation. It contains a stand-alone proportional-integral­differential (PID) loop motion control computer for each casting motor.
  • PID proportional-integral­differential
  • the single board computers receive through a dual port ram interface the desired velocity profile for a casting motor, and at 1 millisecond update rates precisely control the extraction and pushback for each casting stroke.
  • the operator interface is also a touchscreen which provides instantaneous generation and performance of cams which can be customized according to the specific alloy to be cast.
  • cams are stored in three different banks according to their function, i.e., a Custom Cam which is a single cam which allows an operator to instantaneously change any of several parameters which define a cam in order to optimize the casting profile for an alloy in experimentation; a Quick Select Cam which is eight alloy banks of eight cams in each bank which allow the operator to quickly go from any of the eight different pre-generated cams.

  • Quick Select Cam which is eight alloy banks of eight cams in each bank which allow the operator to quickly go from any of the eight different pre-generated cams.
  • the entire control system is generally shown in FIGURE 2.
  • the encoder 13 sends pulses simultaneously to a motion controller and to an encoder and amplifier input board.
  • the motion controller sends a motion command signal to amplifier which is operatively connected to puller motor.
  • the amplified command signal sends a cur­rent torque output reading to the encoder and amplifier input board.
  • the motion controller also sends a signal to the start-of-stroke board.
  • the boards simultaneously feed to an input/output board which, in turn, provides produc­tion performance calculations which are fed to PCS program­mer.
  • the PCS programmer receives temperatures for trend display from the TS2 computer, best shown in FIGURE 5.
  • the PCS program sends signals through the VGA color display and to a cam display for the puller motor.
  • the TS1 computer menu parameters are also fed to the motion controller.
  • FIGURE 3 displays in graphic form a stroke cycle of the puller motor.
  • the motion is in a forward direction, followed by a short re­verse motion, and then a pause before beginning the next cycle.
  • a stroke period is fifteen milliseconds.
  • the strand being cast is moved forward for a period of nine seconds, and is moved in reverse for three seconds, followed by a three-second pause before beginning the next stroke.
  • the system simultaneously checks and adjusts at least four functions, i.e., proportional, integral, differential, and feed forward. As a result, the actual performance of the system is extremely close to the predetermine profile.
  • FIGURE 4 shows a display including the commanded or computed cam curve versus actual curve or actual cam of the caster. Additionally, FIGURE 4 illustrates the sum of differences between the commanded curve versus actual curve which is defined as the following error shown in bar graph form. The display also shows the actual motor torque curve and a motor torque average bar graph. Accordingly, at all times the critical features of the casting operation are displayed.
  • FIGURE 5 is a detailed illustration of the TS2 com­puter which provides data to the PCS program as shown in FIGURE 2.
  • the computer displays simultaneously and controls parameters such as furnace tem­perature, water flow shutdown, billet size, and includes a menu control for the screens, keyboards, bar graphs, real­time clock, and plots data.
