一、前言 武钢一米七冷连轧机和单、双平整机是我国生产冷轧薄板及带钢的重要设备,冷轧工作辊的有效层深达75～125毫米,而直径方向的淬硬层深度一般只有30毫米,所以做好冷轧工作辊的中间修复工作,是一项十分紧迫的任务,具有极其重要的经济意义和现实意义。 为了正确制定冷轧工作辊的中间修复淬火工艺,摸清修复工艺对冷轧工作辊质量及使用性能的影响,我们利用引进的双频淬火机、强制循环台车炉和冷处理设备,对130根直径使用掉30毫米的冷轧工作辊进行了一系列修复工艺的试验,初步找出了冷轧工作 I. Foreword WISCO one meter seven cold rolling mill and single and double flattening machine are the important equipment for producing cold rolled sheet and strip in our country. The effective layer of cold rolling work roll is 75 ~ 125mm deep, while the diameter direction hardened The layer depth is generally only 30 mm, so doing a good job of repairing the middle of a cold-rolled work roll is a very urgent task with extremely important economic and practical significance. In order to correctly develop the middle of the cold-rolled work roll repair quenching process, find out the repair process on the quality of cold-rolled work roll and the use of performance, we use the introduction of dual-frequency quenching machine, forced circulation trolley and cold processing equipment, 130 A diameter of 30 mm using the cold-rolled work roll for a series of tests to repair the process, initially identified the cold-rolled work
