补充资料：轧辊磨损
轧辊磨损
roll wear
Zhagun mosun轧辊磨损(roll wear)车L棍在轧制力作用下将发生不同程度的磨损。轧辊磨损的机理很复杂，铸铁轧辊中的共晶碳化物倾向于疲劳磨损，基体则倾向于磨粒磨损;锻钢的冷轧工作辊和支承辊倾向于粘着磨损，高温下还伴有氧化磨损;冷却和润滑介质可能引起不同的化学磨损包括腐蚀磨损;无水冷的热轧辊还有受塑性支配的磨损机制。至今尚无综合评定轧辊抗磨性的统一指标，即使有些磨粒磨损试验数据也因组间偏差而达不到满意的统一性。鉴于轧辊硬度易于测量，并在一定条件下可以反映耐磨性，所以一般就用径向硬度曲线来近似地表述轧辊的耐磨指标。生产中习惯用轧辊每磨损lmm的轧制量或每修磨一次的轧制量来考核轧辊的质量。 (范坚祥)
