摘要
针对烧结抽风机转子叶片耐磨性较低、易磨穿的现状 ,采用高铬铸铁合金块和喷熔合金粉 ,选择合理的碳弧堆焊电流和喷熔工艺参数联合进行表面强化 ,使表面强化后的叶片使用寿命较原来提高 0 75倍以上。
According to lower wear resistance and easier wear abrasion of rotor blade in sintering exhaust fan,proper electric current of carbon arc build-up welding and the technological parameters of injection welding are altogether selected for surface hardening by use of high chromium cast iron and injection welding alloy powders.Service life of blades after surface hardening is increased by 0.75 times compared with orginal ones.
