摘要
莱钢采用UHP电炉冶炼—LF精炼—连铸—热送—轧制短流程开发生产 2 0CrMnTiH齿轮钢 ,采取了应用精料、加强脱氧、全过程保护浇注等工艺措施 ,使生产出的产品具有末端淬透性带窄、氧含量低、夹杂物少、晶粒细小的特点 ,较好地满足了当前汽车工业对高质量齿轮钢的要求。
The 20CrMnTiH high property gear steel is developed at Laigang adopting process of electric arc furnace short route. By using refined raw material, strengthening deoxidization and total process protective casting etc., the product has the characteristics of narrow Jominy hardenability, low oxygen content, low inclusion content, small grain size, which meets the need of requirement of high property gear steel in automobile industry.
