摘要
针对支重轮用40Mn2-LS圆钢末端淬透性J15硬度值高和RH真空过程中锰含量损失的问题,通过采取优化冶炼、精炼及轧制工艺,提高进RH钢水锰含量等措施,40Mn2-LS大棒材末端淬透性及其他各项技术指标均满足要求。
In view of the problems of high J15 hardness value in terms of the 40Mn2-LS section bar end hardenability for track rollers and the loss of manganese content during operation of RH vacuum process,these measures such as optimizing smelting,refining and rolling process and increasing the content of manganese charged into molten steel in RH were taken,the hardenability of the 40Mn2-LS heavy section bar end and its other technical indexes met the asked requirements.
