摘要
以重载齿轮钢检验退火态带状组织的技术要求为基础,研究带状组织的形成机理,从控制元素偏析、促进元素扩散等方面着手改善钢的带状组织,并从成分优化设计、连铸工艺及轧制工艺方面进行生产工艺优化,生产的重载齿轮钢(CrMo、CrNiMo)退火态带状组织均控制在2.5级以下,满足了技术要求。
Based on the technical requirements for the annealed banded microstructure of heavy-load gear steels,the formation mechanism of banded microstructure was studied,and the banded microstructure was improved from aspects of controlling the element segregation and promoting the element diffusion,the production process was optimized from aspects of composition design,continuous casting and rolling processes.And then,the annealed banded micorstructure of heavy-load gear steels(CrMo,CrNiMo)was controlled below 2.5,which meets the technical requirements well.
