在四辊轧机上热轧厚板,在初轧机上热轧板坯,在钢坯轧机上热轧薄板坯以及在型钢轧机上热轧扁钢等,轧制压力一般较大。若不能正确估算轧制力不是发生断辊,就是常常不能充分发挥轧机潜力。为了充分发挥现有轧机潜力和正确设计新轧机,必须制订合理的压下规程。这就需要可靠而迅速的估算轧制压力。 Rolling thick plates on four-high mill, hot-rolled slab on the first rolling mill, hot-rolled thin slab on the billet mill and hot-rolled flat steel on the section rolling mill. The rolling pressure is generally large. If you can not correctly estimate the rolling force is not the occurrence of broken roller, it is often not able to fully develop the rolling mill potential. In order to give full play to the potential of existing rolling mills and to design new rolling mills correctly, it is imperative that a reasonable reduction rule be established. This requires reliable and rapid estimation of the rolling pressure.
