Definitions

  • the invention relates to a method and apparatus for continuous casting of liquid metals, in particular of liquid steel materials, in which the cast strand formed in a continuous casting mold in a strand guide from support roller segments partly without employment of the support rollers and without drive partly in support roller segments with at least one salaried and driven support role and in which the instantaneous sump tip is measured via an oscillating segment upper frame or an oscillating lifting beam for the driven support rollers or via force monitoring in one or more piston-cylinder drives of the support roller segment and their position via the casting speed and / or secondary cooling of the casting strand is regulated.
  • the invention has for its object to implement the measurement result of the most favorable for the particular application method of measurement in practice for the continuous casting of a continuous casting, i. to propose his practical execution.
  • This object is achieved in that, taking into account the entire length of the strand guide for the hot strand as metallurgical length on the spray jets of secondary cooling and / or the support roller drives the support roller segments, the sump tip in front of a master support roller segment, within a master support roller segment or below is fixedly controlled on a master support roller segment, wherein the casting speed is detected over at least one support roller segment with employee driven driven support roller, and the regulation of the secondary cooling and / or the regulation of the casting speed itself in all preceding support roller segments individually, but matched.
  • the advantage is an exploitation of the entire strand guide as a metallurgical length and thus a high production of maximum usability of the casting material by uniform internal quality.
  • the master support roller segment can be arranged in the horizontal region of the strand guide to detect the sump tip at different operating conditions.
  • a secure control takes place when the master support roller segment is arranged as the last or penultimate support roller segment in the strand guide.
  • a further embodiment provides that the measured values for monitoring the deformation roller adjustment of a soft reduction of the hot strand is used.
  • the control can also be carried out more precisely by operating individual ones of all driven support rollers with or without load compensation control.
  • the apparatus for continuous casting of liquid metals, in particular of liquid steel materials is based on features in which the cast strand formed in a continuous casting mold as a hot strand in a strand guide from support roller segments partly without employment of the support rollers and without drive partly in support roller segments with at least one salaried and driven support role is carried out and used to measure the instantaneous Sumpfspitze an oscillating segment upper frame or an oscillating Hubtraverse for each driven support roller or force monitoring in one or more piston-cylinder drives the support roller segment the Sumpfspitze measurable and their location on the casting speed and / or secondary cooling of the hot strand is adjustable.
  • all spray jets and / or the support roller drives are controlled by a master support roller segment, wherein the casting speed is measured over one or more selected support roller segments with employee, driven support roller, and the control of the secondary cooling in all preceding support roller segments individually, but adjusted to each other is adjustable.
  • the advantages are the retention of the sump tip at a location of the strand length that is favorable for the method used (soft-reduction or hard-reduction) and thus the generation of a more uniform internal quality of the casting strand. As a result, the application of usable material can be increased.
  • the master support roller segment is arranged in the horizontal region of the strand guide. As a result, the proximity of the deformation section and the adjustment paths of the deformation rollers are better taken into account.
  • a further embodiment consists in that the casting speed differences measured on a salaried, driven support roller of a support roller segment preceding the master support roller segment are connected to the regulation of the secondary cooling via a spray water quantity specification control.
  • the data communication with the control station advantageously takes place in that field devices are connected to an axis controller in a terminal box on the master support roll segment and switching valves are provided which are connected to the axis controller and the axis controller via a detachable media coupling by means of a cable package with the Terminal box is connected to a fieldbus module with a programmable logic controller.
  • This device is further developed in that in the axis controller, the stored signals for positioning and synchronizing the support rollers of a neighboring support roller segment, for left or right piston-cylinder drives or for the inlet side or the outlet side, for monitoring the state of the sensors , a support roller segment coding, for maintenance cycles u. Like. Are processable.
  • the hot strand 5a is further supported in a strand guide 8 by support roller segments 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18, transported and cooled by means of a network of spray jets 19a of a secondary cooling 19.
  • all support rollers 20 can be fixed and dragged along or at least one further support roller 21 can be adjusted and provided with a drive 22.
  • the one or more drives 22 are adjustable in speed and / or torque.
  • a support roller segment 9 - 18 consists in each case of a segment upper frame 24 and a segment subframe 26 which can be adjusted by means of pairs of hydraulic piston-cylinder drives 25 to the cast strand thickness.
  • the segment upper frame 24 is oscillatable in a master support roller segment 27 or a specially provided lifting cross-member 28 is oscillatable. It may also, as mentioned above, a force monitoring in the hydraulic piston-cylinder actuators 25 of the support roller segments 9 - 18 are used for Sumpfspitzenar.
  • the casting speed can be detected via one or more of the support roller segments 9-18, each with a engageable, driven support roller 21 and the regulation of the secondary cooling 19 and / or the regulation of the casting speed itself in all preceding support roller segments 9-18 is individually, but coordinated set.
  • This master support roller segment 27 shown in greater detail in FIG. 2 is arranged in the horizontal region of the strand guide 8.
  • the master support roll stand 27 is located as the last or penultimate support roll segment in the strand guide 8 at the end of the metallurgical length 29 of the casting strand 5.
  • the actual value 32 of the casting speed which is measured via the driven support roller 21, is determined from the difference value of the casting speed and used for a spray water quantity specification 33. This results in the control 34 of the secondary cooling 19th
  • field devices 35 are connected to an axis controller 36 in a terminal box 37 on the master support roller segment 27 (FIG. 2).
  • the axle controller 36 is connected via a detachable media coupling 39 by means of a cable package 40 with the terminal box 37 to a field bus module 41 and connected to a programmable logic controller 42.
  • the system can of course be operated in manual mode by an operator default 45 of the setpoint in the drive control 30 to the maximum casting speed 46 (Fig. 1, above).
