废旧锻钢支承辊的再利用技术

Reuse technologies of worn forged backup rolls

由于支承辊辊身局部剥落或使用到设计临界尺寸使其报废,造成很大浪费。本文采用热处理再机械加工、大直径改小直径及镶套修复等技术对废旧锻钢支承辊进行二次利用,为企业节约成本,也符合可持续发展、节能降耗的国家政策。

Since the abandonment of forged backup rollers due to the local spalling of its surface or the surface worn to the critical size caused a great waste, a reuse scheme is proposed in this paper. Three kinds of technologies about the recycling of worn forged backup roils are introduced. They are heat treatment and then machining, big diameter rolls machined to small ones, and repairing with sleeve. The reuse technologies reduced the cost and saved a lot of money.
