摘要
莱钢股份炼钢厂4#矩形坯连铸机通过采用S7-400系列PLC,应用钢坯位置跟踪分段配水技术,优化二冷水配水控制,改造火切机系统,实现连铸机系统的全自动控制,简化了操作步骤,提高了控制精度、设备稳定性、产品质量和产量,中型线H型钢年产稳定在104.7万t左右。
Through adopting S7-400 series of PLC, applying steel billet location tracking section water technology, optimizing the secondary cold water distribution control, reforming fired cutting machine system in 4# rectangular billet continuous casting machine of Laiwu Steel steelmaking plant, automatic control of the continuous casting machine system was realized and it simplified the operation steps, improved the control precision, stability, product quality and yield, medium line of H-beam was stabilized in about 1.047 million tonne annual.
