Definitions

  • the present invention relates to an apparatus for the automatic startup of a continuous casting line, particularly for the production of aluminum or zinc strips.
  • the invention relates to a system installed in a caster for controlling the flow of metal with which the tip of the caster is fed.
  • the startup of a continuous casting machine is a completely manual operation effected by the operator, the person in charge of the caster line, until the standard production conditions are reached, which include:
  • the startup is in fact a very delicate operation that determines the final quality of the product.
  • the duration of a startup is around 15-20 minutes and the operations to be performed are numerous and must be performed in a timely and sequential manner, considering the duration of the event, which is limited.
  • the startup of a continuous casting for aluminum or zinc consists in making liquid metal flow by means of casting channels, passing through a vessel known as a head box, which has a barrier at the end in order to prevent the access of the liquid metal to the inside of the tip while waiting for the required metal temperature to be reached (for aluminum approximately 735°C and 470°C for zinc), the metal is conveyed into the collection vessels (ladles).
  • the operator throttles the flow of metal by means of the level control (actuator), using the manual closing/opening controls that are present on the control post.
  • the operator prepares for removal of the manual barrier (monolith plate) arranged in the end of the head box, making the liquid metal converge toward the inlet of the tip; in this operation, which lasts approximately 20-30 seconds, the operator must pay maximum attention to correctly dosing the quantity of metal, then he must adjust the flow constantly and precisely, assisted by the commands of the operators who wait for the solid strip at the output of the caster (on the front part of the cylinders), until the tip is completely filled.
  • the manual barrier monolith plate
  • the operator controls the level detected by the laser that is present above the head box.
  • the operator engages the automatic metal level adjustment control by pressing the "automatic level” button.
  • This function provides for the flow regulator (actuator) to enter a symbiosis with the laser, giving rise to an automatic adjustment, using the latter as feedback for the closure of the PID adjustment loop.
  • the spraying system is fundamental in order to avoid the adhesion of the aluminum strip on the casting cylinders; graphite performs the role of release agent and also is fundamental in the first minutes of casting; an excessive or insufficient quantity would compromise the continuation of casting.
  • the power-on of the water pump avoids an overheating of the jacket of the steel roller, usually the water must be activated after reaching the surface temperature of the jacket, not before 200°C in order to avoid thermal shocks to the steel, thus the operator must perform manual control, after ascertaining the temperature of the jacket he can proceed with flushing of the cooling water.
  • the aim of the present invention is to improve the prior art.
  • an object of the invention is to provide an apparatus which, in a continuous casting line, or caster, allows to perform the appropriate automatic adjustments in relation to the working conditions required to start the line automatically.
  • Another object of the present invention is to provide a reliable and safe apparatus.
  • an apparatus for the automatic starting of a continuous casting line comprising a vessel which is connected to a tip by means of a gate, the tip feeding a casting housing; the apparatus being characterized in that it includes a laser device which measures the level of the metal within the vessel, a level control device, which adjust the introduction of liquid metal into the vessel, a gate actuator to control the gate for providing a barrier between the vessel and the tip, a transducer for the temperature of the metal inside the vessel, and an electronic management unit; the electronic management unit receiving data from the temperature transducer and from the laser device in order to control the level control device and the gate actuator, adjusting the level of the metal in the vessel in order to ensure a correct and continuous flow of metal toward the casting housing.
  • the automatic starting apparatus is inserted in a continuous casting line for the production of aluminum or zinc strips, known as caster, which is shown schematically in Figure 2 .
  • the apparatus 1 according to the present invention is installed in the caster to control the flow of metal with which the nozzle, or tip, 2 is fed.
  • the tip 2 distributes the molten metal in a casting housing which is constituted by two casting rollers 3 and 4, which are water-cooled by means of a spraying system 5, where the molten metal is cooled and solidified to form a strip 6.
  • the molten metal flows in a channel 8, until it reaches a vessel 9, known as head box, which reaches the tip 2.
  • the strip 6 then passes through a series of apparatuses which include shears 10 and a winding spool 11.
  • the apparatus includes a laser device 12 for controlling the level of the metal inside the vessel 9, a level control device 7, which adjusts the introduction of the liquid metal in the vessel 9 and a gate actuator 13 for the control of the gate for providing a barrier between the vessel and the mouth of the tip.
  • the apparatus also has a temperature transducer, constituted by a thermocouple 14, for controlling the temperature of the metal in the vessel 9, and a PLC management unit with a corresponding operator panel.
  • the operation of the automatic control apparatus according to the present invention is as follows.
  • the molten metal is made to flow into the vessel 9, the end of which is blocked by the refractory barrier, i.e., the gate, which is not visible in the figures, connected to the motorized system constituted by the gate actuator 13, until the required parameters are reached.
  • the refractory barrier i.e., the gate
  • the electronic control system sends a command to the level control device 7, which reaches a set closure position, waiting to reach the preset level, through the drain channel, which is calibrated depending on the thickness of the strip, on the widths and on the alloys.
  • the level of the metal, previously established by a set point, is further confirmed by means of a reading performed by the laser device 12, which actuates the gate actuator 13 so that the motorized refractory barrier opens gradually and progressively, according to a positioning profile stored previously on a work recipe.
  • the level of the metal in the vessel 9 is adjusted by means of an automatic system, in order to ensure a correct and continuous flow of metal toward the casting rollers 3 and 4, in order to avoid poor diffusion of the metal within the tip 2, avoiding so-called freezing.
  • the level control device 7 communicating with the laser device 12, maintains the previously entered set point, i.e. the optimum casting level.
  • the automatic control system adjusts three other fundamental parameters: the speed of the rollers 3 and 4, the cooling water dispensed by the spraying system 5, and the release agent on the cylinders.
  • the invention has achieved the intended aim and objects, providing an apparatus for the automatic start of a continuous casting line that allows to obtain some important advantages with respect to traditional systems.
  • the present apparatus ensures an increase in startups performed successfully and a decrease in the waste of consumables (tip, end dam, fiber).
  • the apparatus according to the present invention furthermore offers an increase in productivity due to the higher percentage of startups completed successfully.
