Optimization-based feedforward control of the strip

2018年4月1日  In tandem hot strip rolling mills, the roll speed of the mill stands is synchronized to ensure a uniform mass flow. A uniform mass flow is desirable to keep the strip tension constant and thus avoid large movements of the loopers which are located between the mill stands in order to control the strip tension. This also improves the

Parameter Estimation for the Tension Model in Hot Strip Mills

2001年9月1日  A hot strip mill is composed of a roughing mill, a finishing mill, and a coiler. In the roughing mill, the reheated slabs are reduced to a thickness of 25-50 mm and narrowed to the desired width. The resulting sheet bar is then transported to the finishing mill, where it is further reduced to the final thickness of 1-20 mm.

Hot Strip Mill Scheduling Under Consideration of Energy

2014年1月1日  Abstract. In steel industry hot rolling is an energy-intensive process as steel slabs need to be heated to about 1,250 \ (^\circ \) C before being rolled on the hot strip mill. Due to time-dependent piecewise energy demand, the total energy consumption for heating is determined by the hot rolling schedule. However, there is no modeling approach ...
