摘要
通过对φ520 mm 9Cr2Mo钢主动支承辊粗车后正火、调质、中频淬火等热处理工艺的分析研究,确定了该类轧辊的热处理工艺参数。经工艺验证,参数可靠,应用于批量生产。
The initiative supported roller for Ф 520 mm 9Cr2Mo steel is analyzied after rough by heat treatments like normalizing, quenching and tempering, midfrequency hardening etc. The process parameters of heat treatment for this kind of miler are definited and confirmed, and are reliable and can be applied to mass production.
