45#钢焊接式空心淬火辊在实际中存在很多加工难点，经常有成品辊因为两端焊接轴头而造成辊身硬度偏低，或者焊接产生内应力而产生裂纹的境况发生从而导致成品辊报废。鉴于此，本文在分析影响产品因为焊接退火及因为焊接产生的应力的基础上，以45#钢空心淬火辊为例，介绍下该类零件的加工工艺和改进方法。
45#鋼銲接式空心淬火輥在實際中存在很多加工難點，經常有成品輥因為兩耑銲接軸頭而造成輥身硬度偏低，或者銲接產生內應力而產生裂紋的境況髮生從而導緻成品輥報廢。鑒于此，本文在分析影響產品因為銲接退火及因為銲接產生的應力的基礎上，以45#鋼空心淬火輥為例，介紹下該類零件的加工工藝和改進方法。

There are a lot of difficulties in the actual machining process of the hollow euenching roller of the 45 steel. There are often rollers with lower hardness due to the welded spindle nose at both ends or cracks because of the internal stress produced by welding, which causes the finished roll scrap. This article analyzes the factors affecting the annealing due to welding and the internal stress due to welding based on this, and introduces the processing method of such parts taking 45# steel hollow quenching roller for example.
