摘　　要：济钢连铸机采用结晶器液压振动技术,由基础级和过程级两级计算机控制系统,实现了对结晶器液压系统的控制,各类位置、压力、温度等传感器信息通过线路传到PLC系统,然后通过工业以太网络连接到基础级(L1级)。通过可视化的操作界面和简便的参数优化,能够及时发现振动中存在的问题,减少漏钢事故,有助于改善铸坯表面质量。Jinan Steel adopted mould hydraulic oscillating technology in the continuous casting machine and used two-level computer control system, that is, basic level and process level, which achieved the control of the mould hydraulic system. Every kind of sensor information such as position, pressure and temperature were input into PLC via many cables and then was transferred to basic level by industry Ethernet network. Operator could find the question by the visual HMI and optimizing parameters simply, reducing breakout accident, improving the surface quantity of slab.
