SYSTEM AND METHOD OF FEEDBACK CONTROL IN MINIMILL PROCESS

摘要

feedback control apparatus and method of the mini mill process is provided. Feedback controller of the mini mill process according to feedback control apparatus for mini mill process for adjusting the casting speed of the thin plate according to the rolling speed degradation due to operation of the finishing mill accident, the strip speed and the strip for the strip to be rolled by the finishing mill measuring the first measurement unit, by multiplying the measured speed of the strip and the strip cross-section, and the mass flow calculating section for calculating a first mass flow of the finishing mill, the cross-sectional area of sheet metal that is cast by the casting facilities for measuring the cross-sectional area 2 and a measuring section, based on the second mass flow of the casting facilities including a cross-sectional area of the first mass flow and the measured sheet for finishing mill, by a control unit for controlling the casting speed of the thin plate, the rolling quality and productivity can be prevented from being lowered. ;
