摘要
对Cr12MoV大型矫直辊进行了热处理试制生产。矫直辊预处理工艺为锻后余热淬火及回火,最 终热处理采用1030℃整体保护加热淬火和230℃两次回火,辊身表面硬度和变形量均达到技术要 求。
The straightening rollers made of Cr12MoV steel have been treated by special process. Pre-heat treating process of the straightening rollers is quenching from forging heat and tempering. The final heat treating process is quenching from 1030℃ and tempering twice at 230℃. The results show that the hardness and the deformation of the rollers have met the specification.
