机车车轮由于运行条件恶劣,受力复杂,使车轮和钢轨的磨耗及车轮轮箍的磨耗、擦伤、剥离、崩裂等故障日趋严重。国产轮箍在实际使用过程中,发生了不少的缺陷,这些缺陷的产生大部分是由于轮箍材质缺陷引起的。因此,有必要对车轮轮箍的金属材质进行研究,以延长其使用寿命。 Locomotive wheels due to poor operating conditions, the force complex, so that the wheel and rail wear and wheel wear, abrasion, peeling, cracking and other failures become increasingly serious. Domestic tires in the actual use of the process, there have been many shortcomings, most of these defects are due to the material defects caused by the wheel. Therefore, it is necessary to study the metal material of the wheel rim to prolong its service life.
