摘要
带钢的前滑值是热连轧过程中一个重要参数,对穿带过程的稳定性起着至关重要的作用。利用后计算轧制辊速比与实际轧制辊速比的偏差,分析1 880 mm热轧前滑模型预报的准确性,这种分析方法具有可行性和有效性;结合后计算与实际辊速比的偏差,适当调整了各机架的前滑系数,提高了穿带稳定性。
Forward slip is one of the most important parameters in hot strip rolling. In order to calculate the roll speed precisely,the forward slip is a precondition. Based on the difference between post calculated roll speed ratio and act roll speed ratio,it is feasible and effective to analyze the precision of forward slip model in 1 880 mm HSM. By the diffidence of roll speed ratio,forward slip coefficient is optimized; therefore the rolling stability is improved.
