摘　　要：马钢大H型钢万能轧机长年连续生产,导致横轭磨损及丝杆存在损伤变形,利用年中大修时间对设备进行探伤及更换,由于此设备为进口设备,从未进行过彻底的大修,检修难度较大。详细介绍了横轭及丝杆的更换引长过程与方法。Years of continuous operation of the H-Beam universal rolling mill of MaS-teel had resulted in wear of the cross beam and damage and deformation of the screw man-drel, so defect detection and components replacement were carried out to the equipment utiliz-ing the scheduled mid-year overhaul. As the equipment was imported and never had complete maintenance and repair, the overhaul work had some difficulties. The process and method of replacement and drawing of the cross beam and screw mandrel are introduced in detail.
