摘要：

针对某轧钢厂650轧机3架横列式，在轧制Φ80～Φ160 mm圆钢时，需要向第2架、第3架轧机提供120，140，150，160和170方等坯料，因此，第1架轧机需要频繁更换轧辊用以改变孔型。当生产合同量小时，换辊频繁会严重影响生产效率。采用的优化设计方案为：由第1架650轧机提供大方坯料160方经过第2架轧机的Φ125～Φ130 mm圆万能孔型中的扁箱孔、立压孔后，进入Φ115～Φ120 mm圆料万能孔型中的扁孔型、立压孔型和椭圆孔型，最后再进入第3架轧机轧制成材。通过轧机孔型优化设计的理论验证与生产试验，证明了新孔型系统可行，可以提高生产效率并降低工人的劳动强度。

The 650 rolling milling machine of a steel mill is open train with three mills. Blanks of 120，140，150，160 and 170 cubic meters should be fed to the second and the third mill during the milling of round steel of Φ80-Φ160 mm，therefore the rollers of the first mill need to be changed frequently so as to change the pass. Frequent roller changing affects the production efficiency severely with small production quantity. The optimized design is that the big size blanks of 160 cubic meters supplied by the first 650 mill passes through the flat box hole and vertical stamping hole in the universal round hole patterns of Φ125-Φ130 mm of the second mill，and then it was fed into the flat hole, vertical stamping hole and oval hole in the universal round hole patterns of Φ115-Φ120 mm，eventually into the third mill for end rolling product. Through the theory verification and production practice of rolling mill pass optimization design，the new pass system was proved to be feasible, and it ould improve production efficiency and reduce labor intensity of workers.
