辊压机辊子表面耐磨层磨损严重时,需要进行堆焊修复。按规定应进行离线堆焊,但离线堆焊时间长,费用高,因此,在实际生产中,有时也采用在线堆焊的方法。本文以我公司CLF140/65辊压机辊子的几次堆焊修复为例,对辊子在线堆焊修复及相应的工艺调整作一介绍。1前期准备及修复时间估算1)清空恒重稳流仓内物料及杂物,以免仓内富集的含铁物料及杂物进入新辊面,造成辊面损伤。2)拆除辊压机进料装置中的进料支架、侧挡板和
Roller roller surface wear layer wear serious, the need for surfacing repair. Off-line welding should be carried out according to regulations, but off-line surfacing a long time, high cost, therefore, in actual production, sometimes also used online surfacing method. In this paper, my company CLF140 / 65 Roller roller several surfacing repair, for example, on-line roller surfacing repair and the corresponding process to make an introduction. 1Pre-preparation and repair time estimation 1) Clear the constant flow warehouse material and debris, so as not to enrich the warehouse of iron-bearing materials and debris into the new roller surface, resulting in roller surface damage. 2) Remove the feed holder, side baffles, and rollers in the roll press feed
