【Abstract】 The authors analyzed working characteristics and failure type of the bearings of heating mill for thin plates and discussed the effects of Al?Mn?Zn elements on alloy type, microstructure texture and properties in this paper. The optimum component of the alloy was determined .By quenching at 820 ℃/1 h mechanical properties of the alloy with optimum component can be raised remarkably, lifetime of the bearing made of the alloy increases from 32 h to 72 h.更多还原
