马钢120 t转炉冶炼洁净钢时
采用≤0
002%S深脱硫铁水、冷料比17%
使用[S
]
≤0.020%低硫优质废钢
应用烟气分析动态控制技术
转炉终渣碱度3.2~3.5
出钢过程加活性灰600 kg
使终点[S
≤0.008%
提高了终点[C
和温度的命中率
终点钢水活性氧为556×10

吹损喷溅下降
石灰等散装料消耗为≤90 kg/t
钢铁料消耗≤1104 kg/t。
As the cleanliness steel was melted by 120 t converter at Masteel
with using ≤ 0.002% S deep-desulphurizing hot metal
cold charge ratio 17%
using[S
≤0.020% low sulphur quality scrap steel
applying off gas analysis dynamic-state controlling technique
controlling converter end slag basicity 3.2~3.5 and adding active lime 600 kg
during tapping
it ensured the end [S
≤ 0.008%
the percentage of hits for end [C
and temperature increased
the end active oxygen content in steel was 556×10
the blowing melting lose and splashing decreased
the lime etc slag-making material was ≤ 90 kg/t and the charge of iron and steel was ≤ 1104 kg/t.
