摘　　要：某钢厂原奥钢联连铸机建成时间较早,设备和自动控制系统已经不能满足企业的实际发展需要,严重制约了企业连铸生产自动化的自我提升。本文主要介绍了连铸机SIMATIC C7控制系统停产和原设计存在的问题,并利用铸机控制系统升级的机会,对原SIMATIC C7控制系统进行了完善和改进。采用了全新的硬件配置和网络通讯方式,保证了铸机的稳定运行。系统投入生产运行后,取得了满意的控制效果,达到了企业连铸生产高速化、全自动化的目的;提高了安全生产条件和设备运行效率,具有显著的综合效益。Due to the early completion of the original Vai continuous caster in a steel plant,the equipment and automatic control system can not meet the actual development needs of the enterprise,which seriously restricted the self-improvement of enterprise continuous casting production automation.The problems existing in the production of SIMATIC C7 control system of continuous casting machine and the original design are introduced,and the original SIMATIC C7 control system by taking advantage of the upgrade opportunity of the casting machine control system is improved.The new hardware configuration and network communication method ensure the stable operation of the casting machine.After the system is put into production and operation,the satisfactory control effect is achieved,and the purpose of high-speed continuous casting production and full automation is achieved.It improves safety production conditions and equipment operation efficiency,and has remarkable comprehensive benefits.
