从辊间接触总压力保持不变和辊间接触单位宽压力保持不变二方面讨论了轧辊变形随轧件宽度变化的规律,而且在变形计算中是基于辊间接触应力相等的原则进行的。通过对轧辊变形规律的讨论,认为对于设计一套适合于中厚板生产的辊型,有必要引入压力加权系数和板宽加权系数参入设计计算。经实际生产应用表明,按此轧辊变形规律和思想设计出的辊型明显地改善了轧辊磨损和板凸度。
The relationship between the deformation of the roll and the width of the rolling stock is discussed in terms of the total pressure of the contact between the rolls and the pressure of the contact unit between the two rolls. In addition, the calculation of the deformation is based on the principle that the contact stress between the rolls is equal. Through discussing the law of roll deformation, it is considered that it is necessary to introduce the pressure weighting coefficient and plate width weighting coefficient into the design calculation for designing a set of roll shape suitable for plate production. The actual production and application shows that according to the roll deformation law and design of the roll shape significantly improved roll wear and plate crown.
