加拿大安赛乐米塔尔多法斯科钢公司通过后失效分析,发现锻钢辊断裂有两种模式:轧制诱导锻钢辊断裂和供货商制造缺陷引起的断裂。通过制造商近年的努力,锻钢辊的耐磨损性、表面和内部质量都得到很大改善。然而,轧制环境经常不稳定,锻钢辊内应力异常高。在高应力条件下,锻钢辊表 After the failure analysis by ArcelorMittal Dassisco Steel Canada, it was found that there are two modes of forging roll breakage: rolling induced fracture of forged steel roll and fracture caused by supplier’s manufacturing defect. Through the efforts of the manufacturer in recent years, forging steel wear resistance, surface and internal quality have been greatly improved. However, the rolling environment is often unstable and the stress in the forged steel rolls is abnormally high. Forged steel roller table under high stress conditions
