保淬透性齿轮钢20CrMnTiH的工艺实践

PRODUCTION PRACTICE OF 20CrMnTiH GEAR STEELWITH GUARANTEED HARDENABILITY

介绍了河钢宣钢采用“150t转炉—LF精炼—连铸—热轧”短流程生产窄淬透性带20CrMnTiH齿轮钢工艺实践。通过对转炉、LF精炼、连铸工艺参数的合理控制，能够批量生产出符合GB/T5216-2004要求的20CrMnTiH齿轮钢。

This article introduced the production processes of 20CrMnTiH gear steel by 150 t converter-LF-CC-hot rolling short route. According to controlling the process parameters of converter and LF refining and billet continuous casting reasonably, it was achieved that the batch production of 20CrMnTiH Gear Steel meeting GB/T 5216-2004.
