TWI253360B - Feed opening adjustment of segments for continuous casting systems - Google Patents

Abstract

The invention relates to a method and device for adjusting the feed opening of segments for continuous casting device, especially position-controlled segments for slab and thin-slab continuous casting devices which comprise a strand guide (1) with segments (2) for a predetermined guidance of a cast strand using measuring and control signals, wherein the measuring and control signals are processed in at least one system unit (14) directly on the respective segment (2) and the set values are fed to the segment (2) by a superordinate control system (10) via a field bus (11), for example a profibus and, and a power supply (12). Actual values are returned to the control system (10) via the field bus (11) as the result of control or as a process status. The system units (14) present on the segment (2) are supplied with segment-specific data, such as rigidity coefficients, roller diameter, control parameters, feed opening basic settings and adjustment quota. The invention also relates to a device for carrying out the method.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method and apparatus for adjusting the gate width of a segment of a continuous casting apparatus, particularly for use in a position adjustment of a steel sheet-and thin steel sheet continuous casting apparatus. The invention comprises a strip guide 1 having a segment for guiding a cast strip, which is adjusted in the case of measuring and adjusting signals. Furthermore, the invention relates to a device for carrying out the method. In the background art, there are position- and pressure-regulated segments (fragment cylinders) in a continuous casting apparatus. Here, in particular, for the Softreduktion (SR) program and the Liquid_Core-Reduction (LCR) program, the segment is adjusted by the hydraulic cylinder and the associated measurement - adjustment and control elements. Typically, the adjustment and control elements required for this purpose are located in the remote switching device of the continuous casting apparatus. This regulation and/or control action is destroyed together when the transmission element or transmission line fails. German Patent No. DE 100 28 304 A1 discloses a method and a device for decentralizing measurement data obtained by means of a sensor on a continuous casting ingot in a program computer of a continuous casting apparatus. Casting data processing. The purpose of this prior art is to electronically process the casting data measured by the sensor in an efficient manner and thereby simplify the apparatus for this purpose. To this end, the measurement-and control data is collected in the cooled field busbar module on the continuous casting equipment and becomes a confluence 1253360 row signal sent to a *busbar line, and at least 5 hailian I buy 纟Stored in, and/or processed in, the control device of the stomade equipment. Thus the data path is greatly shortened and the device is simplified. Another advantage of this technique is that the data varies depending on the ingot mold, for example, regarding the thickness of the copper plate, the degree of consumption, the state of the thermal sensor, the state of the thermal sensor and/or the resistance sensor, And the maintenance cycle can be stored in a field busbar module on the continuous casting ingot mold in a callable manner. Document International Patent Publication No. WO 99/46071 discloses a method for adjusting a roller segment hand for a continuous casting apparatus, the roller segment having a segment inlet side, a segment exit side, and a pair of roller carriers, the roller The sub-porters each carry at least two rollers extending over a support range. These roller carriers are mutually adjusted relative to each other via an adjustment unit provided on the inlet side of the segment and on the exit side of the segment. Each adjustment unit adjusts a single two hydraulic cylinder unit, which is arranged on both sides of the support area. The main point of the adjustment method disclosed here is that the hydraulic cylinder unit can be adjusted according to the position and pressure. Through the hydraulic cylinder unit, the roller can be moved to a metal strip guided by the roller according to the position. And if the pressure in each hydraulic cylinder unit reaches a threshold, the hydraulic cylinder unit can be switched from the position adjustment operation mode to the pressure adjustment operation mode. The present invention is directed to these background art, the object of which is to directly mount a decentralized control and adjustment system with associated modules on a segment or directly on a hydraulic cylinder, thus creating a "smart" (Intelligent) ) Fragment, this smart segment ensures that the job continues even if the communication data fails.
