摘　　要：万能轧机装配精度的影响因素主要为平辊系统、立辊系统以及导卫系统,较大的精度偏差会导致偏头、型钢尺寸失真、翼缘尺寸厚薄不均、划伤以及堆钢的缺陷,通过对工装精度的标准、偏差以及修复措施进行优化,可有效提高万能轧机的工装精度,使因工装精度低而产生的缺陷废品数量大幅度降低,成材率提升0.5%。Influence factors of universal mill assembly precision mainl y are horizontal roller system, vertical roller system and guide system. The large deviation will cause bending, steel size distortion, uneven thickness of flange size,scratching, and steel-heaping. By optimizing the standard, deviation and repair measures of assembly precision, the precision of the universal mill is effectively improved. The number of defective waste produced by the low assembly precision is greatly reduced, and the yield of the material is raised by 0.5%.
