摘要: 萊鋼特鋼廠20CrMnTiH鋼材成分波動較大,淬透性帶HRC8~10,范圍較大,制約了齒輪鋼質量的進一步提高.通過研究,發現鑄坯中心偏析尤其是碳偏析為主要問題.通過工藝優化采取各項措施,尤其增加電磁攪拌后,中心碳偏析得到明顯改善;C控制在0.19%~0.20%的爐次達到了95.6%;淬透性帶控制在HRC6內的達到了92.1%;在HRC4內的達到了86.2%;提高了產品質量,滿足了用戶需求.

Abstract: The component fluctuation of 20CrMnTiH steel in Laiwu Special Steel Plant was large,the-hardenability bands belt was HRC 8-10,this constrained the further improvement of gear steel quality.Based on the research,it was found that center segregation especially carbon segregation in blooms was the major prob-lem.By taking measures,especially the increase of electromagnetic stirring,the center carbon segregation was markedly improved;C control between 0.19%~0.22% reached 95.6%;hardenability bands belt control in HRC 6 reached 92.1% and in HRC 4 reached 86.2%.The quality of products is improved and the needs of users are met.
