Variation Mechanism and Its Solution of Decoupling Technological Parameters for the Combined Shape and Gauge Control System in Hot Strip Mills

摘要: 通过对建立的耦合关系模型的分析,指出 Mp,Mw,Q,Kp和 Kw是决定工业轧机板形板厚综合控制系统耦合特性的参数.它们随实际轧制生产条件的变化而改变.采用有限元模型,结合工业轧机系统实测数据,给出 1700 mm热连轧机耦合特性参数的求解方法,该方法为板形板厚解耦设计的工业应用提供了切实可行的途径.

Abstract: Since decoupling technological parameters, Mp, Mw, Q, Kp and Kw, of the combined shape and gauge control system vary widely as the rolling condition by theoretical analysis of developed mathematical models and industrial experiment on the production mill, this paper develops mathematical models by FEM for calculating decoupling technological parameters of 1 700 mm hot strip mill. The calculated parameters are applied in the proudction mill and proved to be effective.
