延长风扇磨煤机检修周期的试验研究

Experimental investigation on how to extend overhaul circle of fan mill

通过对风扇磨煤机叶轮材料进行理化分析和性能检测,确定了叶轮失效方式,为风扇磨煤机叶轮材料选择提供了理论依据。同时,对修复风扇式磨煤机打击轮的各种焊接工艺进行了评定,选择了焊接材料。

Rotor＇s K-R model is confirmed,through physical and chemical analysis and performance evaluation of rotor＇s material of fan mill which provide theoretical foundation for rotor＇s material.This paper also evaluates welding procedures for smash wheel restoration and selects welding material.
