全液压矫直机工艺数据采集分析管理系统

太原重工与太原科技大学联合研制的四重式全液压可逆十一辊矫直机,其二级控制系统包含了自动化站、主操作站、监控站、工程师站、服务器集群的分布式计算机控制系统;全线二级系统与回火炉操作台的PC机相连,采集板厚、板宽、材料编号等实时板材数据。在过程计算机工程师站中设置数据库,针对不同材质、温度、板型、板宽和板厚,建立工艺模型,计算出矫正压力、矫正次数及所需压下量的理论数据,再经过试验,计算出矫直机线性弹跳、非线性机架变形、总结出所需压下量的经验数据,两者结合生成矫直机压下量工艺数据。实践证明:该系统运行良好,安全可靠。

Acquisition and analysis management system for process data of full-hydraulic straightener

The application of the secondary control system for full-hydraulic 11-roll straightener developed by Taiynan Heavy Industry Co., Ltd. and Taiyuan University of Science ＆ Technology is introduced. The control system contains automation station, main operation station, monitoring station, engineer working station and distributed computer control system, and is connected with PC on tempering furnace control console to collect the re- al-time data such as steel plate thickness, width and material serial number. The database is set in the engineer working station to establish process model aeeording to the material quality, temperature, plate cut, plate width and thickness, and calculate theoretical data of straightening pressure, number of times and rolling reduction. ＇after testing, the linear bounce and nonlinear frame deformation of the straightener is achieved by calculation, and then the empirical data of the rolling reduction is obtained. In combination with the theoretical data and the empirical data, the rolhng reduction process data is generated. The application result shows that the straightener works well.
