摘要

GH2132合金（1.90%～2.30%Ti）重熔过程中Ti烧损量大（Δ[Ti

]

0.37%～0.57%）

重熔中、后期钢中Ti含量仅为1.83%～1.89%。通过采用（%）CaF

:Al

:CaO:TiO

=75:15:5:5渣系替代原CaF270%+Al

30%渣系

控制渣中不稳定氧化物（SiO

+FeO）≤0.6%、冶炼过程熔速控制从原6.1～6.3 kg/min降至5.3～5.6 kg/min等工艺措施

电渣锭各部位的Ti含量为2.06%～2.21%

Ti烧损量Δ[Ti

]

降至0.19%～0.34%。电渣锭锻造开坯后取样对夹杂物进行检验

发现通过工艺调整后夹杂物也有明显改善效果

D类细系夹杂物控制在0.5级以下

符合供货要求。

Abstract

The GH2132 alloy (1.90% ~2. 30%Ti) has the problems of large loss of Ti element ( A[Ti

]

0. 37% ~ 0. 57% ) in ESR process

the Ti content in steel is only 1. 83% ~ 1. 89% in ESR middle and last period. By adopting (/% ) CaF： Al

： CaO： TiO

=75： 15： 5： 5 slag system to replace original CaF270% + Al

0% slag system

the unstable oxide (SiO

+ FeO) in the slag is controlled to be less then 0. 6%

and die controlled melting rate of the smelting process decreases from 6. 1 -6. 3 kg/min to 5. 3 -5. 6 kg/min

etc technological measures

as a result

the Ti content in steel at ESR ingot each part is 2. 06% ~2. 21%

and the Ti burning loss A[Ti

]

decreases to 0. 19% ~0. 34%

ESR ingots are sampled to check the inclusions after forging

and it is fo

und that the inclusions have also been significantly improved after the process adjustment. The class inclusions of D fine system is controlled below rating 0. 5

which meets the requirements.
