摘要
介绍轧机梅花接轴的梅花瓣部位磨损后,采用新焊补材料和预热接轴进行堆焊,而后低温回火加缓冷的新修补方法,达到减少工作磨损、使用寿命提高一倍、经济效益显著的效果。
When the rolling mill spline axis wore out, it could be repaired by welding with the new weld fill material after the axis was pre-warmed up, then the repaired axis was backfired in low temperature and under tardiness cooling. This new repair method could reduce the working abrasion of the axis, and make its service life longed double. A remarkable economic benefit was achieved.
