轧制时接触变形区长度是计算轧制力的一个比较重要的参数之一。对它确定的是否正确,将对轧制力的计算结果有直接影响。在确定接触变形区长度时,即使是热轧,也必须考虑轧制时轧辊弹性压扁的影响。因为,就是在热轧普通碳素钢板带 The length of the contact deformation zone during rolling is one of the more important parameters for calculating the rolling force. Whether it is correct or not will have a direct impact on the calculation of rolling force. In determining the contact deformation zone length, even if the hot-rolled, rolling roll must also consider the impact of elastic crushing. Because, is hot-rolled ordinary carbon steel plate
