摘要

2205双相不锈钢6.2 t 200 mm×1250 mm扁锭（/%:0.015~0.016C，0.15~0.16Si，1.35~1.39Mn，0

005~0.006S，0.023~0.024P，22:78~22.95Cr，5.40Ni

3.15~3.17Mo，0.193~0.194N）由20 t双极串联抽锭电渣重熔炉生产。通过采用50CaF

-19Al

-19CaO-6MgO-6SiO

液态熔渣

控制抽锭速度12 mm/min

电极熔化速度1100~1200 kg/h等工艺措施

扁锭表面质量良好

表面修磨量≤3 mm

满足轧制要求。

Abstract

The 6.2 t 200 mm x 1250 mm slab ingot of 2205 dual-phase stainless steel (/% : 0.015-0.016C

0.15-0.16Si

1.35-1.39Mn

0.005-0.006S

0.023-0.024P

22.78-22.95Cr

5.40Ni

3.15-3.17Mo

0.193-0.194N) is produced by a 20 t duplex electrode series drawing ingot elector-slag remelting unit. With the process measures including using 50CaF

-19Al

-19CaO-6MgO-6SiO

liquid slag series

controlling ingot drawing speed 12 mm/min and electrode melting rate 1100-1200 kg/h

the surface quality of slag ingot is better

the surface grinding amount is ≤3 mm to meet the requirement for rolling.
