摘要
转炉炼钢除尘用Ｄ７００－ １３－ Ⅱ型高速高压风机叶轮叶片因受烟气腐蚀、烟尘磨粒磨损而容易失去动平衡导致报废。采用ＥＤＺＣｒ 型高铬合金堆焊焊条和Ｎｉ－ ０２Ｃ 镍基合金粉末对风机叶轮进行堆焊与喷焊表面强化工艺，解决了风机叶轮腐蚀与磨粒磨损的修复问题，且提高使用寿命１５ 倍。
The impeller vane of D700-13-Ⅱ high speed and high pressure blower is easily damaged with losing dynamic equilibrium because it is corroded by flue gas and weared by dust in flue gas.Taking EDZCr high chrome alloy welding rod and Ni-02C nickel base alloy powder as material to do built up welding and injecting welding on the impeller of blower,the repairing question of impeller of blower is solved and the service life of impeller is increased by 1.5 times.
