卷取机转矩控制技术优化卷形

Torque Control Technique of Coiling Machine to Optimize Coil Shape

优化卷筒转矩控制和夹送辊转矩控制,消除钢卷错层和塔形,提升钢卷质量。首先,通过钢卷错层和塔形出现的位置分析产生的原因;其次,优化卷筒张力和设定转矩,防止精轧末机架抛钢瞬间卷筒失张;其三,优化夹送辊负转矩控制,保证卷筒与夹送辊之间有合适的带钢张力。最后,对调整后的卷形效果进行分析和评价。

The optimizations of mandrel torque control and pinch roll torque control remove the staggered--floor and telescoping to promote the quality of the coil. Firstly, the reasons of causing for staggered--floor and telescoping are analyzed by the position of the staggered--floor .Secondly, the mandrel tension and the torque reference are correc- ted to prevent the mandrel from losing tension when the strip leaving the last stand of finishing mill. Thirdly, the negative torque of the pinch roll is corrected to ensure the suitable strip tension between mandrel and pinch roll. Fi- nally, the adjust effects are analyzed and evaluated.
