中文摘要：

针对宝钢特殊钢事业部新建的国内首条合金板带热轧炉卷生产线热处理项目,采用Visual C＋＋6.0,Siemens的WinCC 6.2和SQL Server 2005等开发了中厚板热处理加热过程在线控制应用软件.软件主要包括人机交互界面、过程计算模型、通信软件和实时数据管理系统,详细介绍了过程计算核心模型的建模原理.在线应用结果表明,该系统与基础自动化系统结合不仅降低了操作强度,而且大幅度提高了加热工艺的控制精度和钢板的加热质量.

英文摘要：

An online control software was developed by Visual C＋＋6.0,WinCC 6.2 of Siemens, SQL Server 2005,etc.,for the new heat-treatment system of alloy plate/strip hot-rolling line in Baosteel.Mainly the software comprises a man-machine interface,process computation model,communication softwares and real-time data management system.The modeling principle is described in detail.The online running results of the software developed showed that combining the plate-reheating system with basic automation is able to not only reduce the operation complexity but also greatly increase the precision of temperature control and quality of plates in the heating process.
