Definitions

  • the invention relates to an adjusting device for the narrow side of a continuous casting mold according to the preamble of claim 1, and a method for adjusting a narrow side of a continuous casting mold according to the preamble of claim 10.
  • At least one narrow side of the mold can be adjusted relative to the other narrow side, or both narrow sides relative to one another, in order to set a different format for the cast strand.
  • this is off DE 197 48 305 A1 or WO 2009/144127 A1 known - in these publications, for the purpose of adjusting the casting width, at least one narrow side of the mold is adjusted by means of a narrow side adjusting device or an adjusting element which acts in this way and which is connected to the narrow side.
  • the individual positions of the axes along which the adjustment drives act for a respective narrow side of the mold can be converted into a side-related mold conicity and an opening width of the mold (in different horizontal planes: upper edge, lower edge, Bathroom level) must be converted accordingly.
  • the basis for calculating a nominal width in a continuous casting mold is the desired cold width of the cast strand format. From this value, so-called temperature shrinkage factors are used to convert to the adjustment of the narrow side of the mold, thus realizing the desired width setting (cold dimension to warm dimension in the mold). The same applies to the so-called mold conicity. Such a conicity is necessary in continuous casting in order to reduce the temperature shrinkage of the still hot steel, i.e. Shrinkage in width in the mold or above the height of the narrow side of the mold, to be compensated solely within the given mold height.
  • the narrow sides of the mold are set to the respective setpoint values, it being possible to change the position of the narrow sides of the mold during the casting operation.
  • Such process-dependent changes in the positions of the narrow sides are used for desired changes in width, or also for necessary adjustments (conicity and width) when the steel quality is changed and / or when the casting speed is changed.
  • the position of the narrow sides of a continuous casting mold is controlled by the automation of the continuous casting plant.
  • a setpoint for setting the Width synonymous with the position of the mold narrow sides, and the narrow side taper specified by the basic automation.
  • the adjustment of the mold narrow sides to predetermined setpoints takes place on the basis of a calibration of the measuring system of the narrow side adjustment device, this calibration being carried out as a rule at ambient temperature before the start of casting. With such a calibration, the mechanical adjustment system is generally assumed to be a constant and unchangeable parameter.
  • the invention is based on the object of optimizing the setting of the narrow sides of a mold in the continuous casting process with a view to a consistently high quality of products produced therewith and thereby also increasing operational reliability.
  • An adjusting device is used to adjust the narrow side of a continuous casting mold.
  • the adjusting device includes At least one actuator, which is connected to the narrow side of the mold, in particular by a joint, and a control device for generating an actuating signal and for controlling the actuator with the actuating signal, whereby the narrow side of the mold is adjusted in the direction of an adjustment axis in a target position during operation of a continuous casting plant can be.
  • On the actuator on parts thereof and / or adjacent to the actuator, at least one temperature sensor is arranged, which is in signal connection with the control device, for example wired or wirelessly via a radio link or the like.
  • This temperature sensor can be used to measure a change in temperature on the actuator or on parts thereof, particularly during operation of a continuous casting plant.
  • the control device comprises a computing unit with which a temperature change detected by the temperature sensor for the actuator and / or parts thereof can be converted into a thermally induced change in length.
  • the control device is programmed in such a way that this calculated change in length in the direction of the adjustment axis is used to determine a correction variable which is taken into account when the actuator is actuated with the actuating signal.
  • the invention is based on the essential knowledge that temperature changes occurring during the continuous casting process on the actuator, on parts thereof and / or adjacent to this actuator are detected with at least one temperature sensor, these temperature changes then being linear expansions or thermally induced with the computing unit of the control device Changes in length of the actuator or parts thereof are converted that occur on the actuator and / or its components. Taking these calculated changes in length into account, the invention then determines correction values which are suitably taken into account for the control signals with which an actuator for adjusting a narrow side of the mold into its target position is controlled. As a result, corrected adjustment paths are thus implemented for an actuator connected to a narrow side of the mold, so that the changes in length that occur as a result of temperature changes are suitably compensated.
  • the actuator with which an adjustment and / or adjustment of a narrow side of the mold takes place can be formed from a hydraulic cylinder or from an electromotive spindle drive. Details of these possible embodiments of the actuator are explained elsewhere below.
  • changed component lengths of the actuator can be determined according to the invention, which correspond to said calculated changes in length of the actuator or parts thereof.
  • a change in length can occur on a quill tube or on a spindle that is movably guided in it, and when a hydraulic cylinder is used, a change in length can occur on its cylinder rod.
  • these changes in length are appropriately taken into account when controlling the actuator, so that when adjusting the narrow side of the mold according to its target position, there are no deviations or inaccuracies, not even with fluctuating temperatures in the casting operation.
  • thermo sensors can be used for the temperature measurement on the actuator of an adjusting device according to the invention, e.g. Thermal elements, semiconductor temperature sensors, integrated temperature sensors, fiber-optic temperature sensors, NTC's, PTC's, and / or infrared sensors.
  • the aforementioned correction of the adjustment path for the actuator is to be understood as meaning that if the thermal change in length of the actuator and / or parts thereof is positive or becomes greater, then this change in length from the adjustment path, the otherwise with the actuator in the direction of the pitch axis would be set, deducted or subtracted.
  • a suitable correction value that is applied to the control signal with which the actuator is controlled.
  • a temperature sensor can be attached to the outside of a narrow side of the mold. This ensures that fluctuating temperatures that occur within the mold during the continuous casting process and are also propagated to an actuator connected to a narrow side of the mold or to a part thereof, can be reliably detected or measured. In addition and / or as an alternative, it is also possible for a temperature sensor to be arranged or received in a narrow side of the mold, with the same advantages as just explained.
  • a temperature sensor can also be integrated in a position transmitter of the adjusting device according to the invention, which is in signal connection with the control device. This takes place with the proviso that such a position transmitter is arranged at least adjacent to or in the vicinity of the actuator, or can also be attached to the actuator itself.

  • uniform actuation of the two actuators 14 enables the mold narrow side 11 to move in the direction of the adjustment axes A in order to adjust the casting width for the continuous casting mold 12. If the two actuators 14 are controlled differently from one another, this leads to a change in the inclination of a narrow mold side 11 with respect to the vertical, and thus to an adjustment of the conicity of this narrow mold side 11.
