实现初轧机压下量自动控制的系统分析

Analysis of the Automatic Control System of Blooming Mill Press

介绍以PLC为核心的初轧机压下量自动控制系统，重点叙述压下量由手动控制改为自动控制的实现过程及需要解决的若干问题。并揭示了如何通过轧制规程表的分析而建立调节规律的数学模型的方法，从而有利于实现PLC对轧机压下量调整，系统投入运行后，产品尺寸偏差较小，完全满足生产要求。

This paper introduced the automatic control system of blooming mill press, especially emphasized on the realization of press quantum from manual to automation and the problem to be solved, Also it discussed the method of etablishing the regulation rule model through analysis of the rolling rules tables, which is benefit for realization of PLC regulation the Prees quantum. With the system being Put into practice,the bias of the product size is smaller and the Production requirements are met.
