摘　　要：对影响双真空(VIM+VAR)熔炼30CrMnSiNi2A钢屈服强度(σ0.2)的因素进行了分析。结果表明,C,Si对该钢σ0.2影响较大,为了确保σ0.2满足技术规范的要求,C,Si含量宜控制在上限;在规定200～300℃回火温度范围内,较高的温度回火对提高σ0.2有利。The factors governing yield strength(σ02) of 30CrMnSiNi2A steel melted by VIM+VAR were analyzed The results show that the C and Si contents have significant effect on the yield strength of this steel To guarantee the yield strength to meet the requirements of the specification, the elements C and Si must be controlled to the upper limit,and the tempering temperature must be in the higher figures at 200～300℃ 
