某厂冷轧带钢用的ＧＣｒ１５钢轧辊是外购坯料自己加工制作而成，轧辊使用寿命偏短，辊耗较高。研究表明，其主要原因与轧辊崩块剥落有关。本试验拟就轧辊崩块剥落的原因及其他影响轧辊使用寿命的原因进行分析，并提出改进措施。１试验内容１１崩块剥落断口观察ＧＣｒ１... GCr15 steel roll used in a cold-rolled steel strip is purchased from the processing of their own blank, roll life is short, higher roll consumption. The research shows that the main reason is related to the spalling of roll block. This test intends to roll off the collapse of the collapse of the reasons and other factors affect the roll life of the reasons for analysis and propose improvements. 1 Test Content 1  1 collapse block fracture observation GCr1 ...
