摘要

试验了Incoloy825合金电极（/%:0.01C

0.21Si

0.41Mn

0.007S

0.019P

22.33Cr

39.08Ni

3.04Mo

2.14Cu

1.17Ti

0.17Al）由3t中频炉+3tAOD冶炼

并经抽锭电渣重熔成280mm×325 mm坯（/%:0.01C

0.21~0.23Si

0.40Mn

0.005S

0.023~0.024P

22.48~22.50Cr，39.10~39.13Ni

3.05~3.07Mo

2.14~2.15Cu

1.00~1.10Ti

0.15~0.18Al）。试验表明

Incoloy825合金方坯抽锭电渣重熔过程中

由于Ti烧损

渣中TiO

含量不断增加

熔渣的粘度也不断上升

导致钢渣不易分离。通过改进抽锭电渣重熔渣系配比

采用（/%）57CaF

2，

15CaO，5MgO

15Al

5SiO

3TiO

渣系以及控制电极熔化速度680kg/h

重熔过程加0.43kg/t铝粒以控制Ti烧损

使Incoloy825合金铸坯表面质量明显改善。

Abstract

The electrodes of tested Incoloy825 alloy (/%: 0.01C

0. 21Si

0.41Mn

0.007S

0.019P

22.33Cr

39.08Ni

3.04Mo

2.14Cu

1.17Ti

0.17Al) are melted by 3t medium frequency induction furnace + 3t AOD

and the 280mmx325mm withdrawing blooms (/%: 0.01C

0.21~0.23Si

0.40Mn

0.005S

0.023~0.024P

22.48~22.50Cr

39.10~39.13Ni

3.05~3.07Mo

2.14~2.15Cu

1.00~ 1.10Ti

0.15~0.18Al) are remelted by ESR process. The test results show that during ESR bloom withdrawing process of Incoloy825 alloy

due to Ti burning loss the TiO

content in slag increases continuously and the viscosity of slag also uninterrupted increases led to difficult separation of sl

ag and steel. By improving ingredient of slag for withdrawing bloom ESR

using (/%) 57CaF

15CaO

5MgO

15Al

5SiO

3TiO

slag series and controlling electrode melting rate 680kg/h and adding aluminium shot 0.43 kg/t in ESR process to control Ti burning loss

the surface quality of casting bloom of Incoloy825 alloy improves obviously.
