摘　　要：从宝山钢铁股份有限公司2050热轧卷取G辊道速度控制原理出发,指出原速度控制方法不足,分析了薄带钢尾部在G辊道"飘"起从而导致在卷取夹送辊前出现拱钢、断尾现象及尾部松卷等问题的原因,设计了G辊道新的带钢尾部滞后速度控制方法,通过对G辊道速度模型的优化,使带钢能够平稳地通过G辊道,避免了带钢尾部"飘"起的发生。Based on principles of G roller table speed control in the coiler area for Baosteel 2 050 mm hot rolling mill, the drawbacks of the original speed control method are pointed out. The reasons of the faults such as strip humping up, tail fracture and coil loose due to the strip tail ＂floating＂ are analyzed.A new method of the thin strip tail lag speed control on G roller table is presented. With this optimized G roller table speed control model, the thin strips are allowed to pass G roller table smoothly without the occurrence of tail ＂floating＂.
