本文介绍了ＬＢ－３５２液位计在连铸结晶器钢水液位测量与自动控制中的应用。用根据连铸结晶器尺寸、预先制做的长形试块，模拟连续铸钢过程中，结晶器内钢水液位的波动等方法，对ＬＢ－３５２液位计进行初步的标定和调试。在连铸热调过程中，对其进行与拉坯实际情况逐步迫近的细调试，最终达到了ＬＢ－３５２液位计与ＰＬＣ控制器、液压伺服系统联锁控制塞棒动作。调节由中间包流入结晶器钢水的流量，实现了结晶器内钢水液位在设定点达到动态平衡的目的，满足了连铸系统的高自动化要求。
This article introduces the LB-352 liquid level gauge in the continuous casting mold liquid level measurement and the automatic control application. The LB-352 liquid level meter is calibrated and adjusted according to the size of the continuous casting mold, the pre-fabricated long test block, the simulation of the continuous casting process and the fluctuation of molten steel level in the mold. During the continuous casting heat transfer process, it was gradually fine-tuned to the actual situation of the drawing process, and finally the LB-352 liquid level gauge and the PLC controller and the hydraulic servo system were interlocked to control the stopper rod movements. The flow rate of the molten steel flowing into the mold by the tundish is adjusted so as to achieve the purpose of achieving the dynamic balance of molten steel level at the set point in the mold and meeting the high automation requirements of the continuous casting system.
