摘要/Abstract

摘要： 长城特钢采用 30 t EAF +VOD ESR(2～3 t锭 ) 825mm轧机试生产了 1Cr12Mo ,2Cr12NiMo1W1V等12%Cr型叶片用钢。结果表明 ,当 1Cr12Mo钢成分为 (%) :C 0.13～0.15 ,Cr 11.70～11.90 ,Ni 0.46～0.55 ,Mo 0.34～0.47,以及2Cr12NiMo1W1V钢成分为 (%) :C 0.22～0.25 ,Cr 11.30～11.68,Ni 0.67～0.95 ,Mo 0.96～0.99,W 0.96～0.98,V 0.22～0.25时 ,钢中的δ 铁素体含量δ_F ＜5 % ,满足标准要求。电极母材精炼时 ,用Ca-Si,Si-Al-Ba终脱氧有利于在电渣过程去除钢中夹杂物

Abstract: The 12%Cr type steels- 1Cr12Mo and 2Cr12NiMolW1V for turbine blades have been pilot produced by 30 t EAF+ VOD-ESR(2~3 t ingot)-825mm mill at Changcheng Special Steel.The results showed that as 1Cr12Mo steel analysis was C 0.13～0.15 ,Cr 11.70～11.90 ,Ni 0.46～0.55 ,Mo 0.34～0.47 and 2Cr12NiMolW1V steel analysis was C 0.22～0.25 ,Cr 11.30～11.68,Ni 0.67～0.95 ,Mo 0.96～0.99,W 0.96～0.98,V 0.22～0.25,the δ-ferrite content δ_F in steel was less than 5% to satisfy the requirement of standard; and the Ca-Si, Si-Al-Ba used as finishing killing agent during electrode melting was favourable for inclusion removal in steel during ESR process.
