Title:
タンデム冷間圧延機の制御システム
Document Type and Number:
Japanese Patent JP7375947
Kind Code:
B2
Abstract:
In thickness control processing, transfer processing of an entry thickness He(N) is performed (step S1). In the transfer processing, data of the entry thickness He(N) is transferred from a position P11 to a position P12 at the same speed as the speed of a material to be rolled M. Subsequently, an amount of change in a thickness ΔH(N) is calculated (step S2). The amount of the change in the thickness ΔH(N) is calculated based on data of a delivery thickness Hd(N) and data of a transferred thickness Hc(N) transferred to the position P12 at a timing when the data of the delivery thickness Hd(N) is measured. Then, a target entry thickness He(N)_tgt is calculated (step S3). Subsequently, a manipulated amount of rolling speed VR(N−2) and VR(N−k) are calculated (step S4).
