摘要

对比分析了实芯钙线(99.35%Ca)和钙铁线(30.53%Ca)在160 t、230 t和300 t LF精炼过程应用的冶金效果。喂纯钙线前后平均钢水的酸溶铝、硫含量和温度分别为0.036%、0.010%、1 587℃和0.029%、0.008%、1584℃。与喂钙铁线相比

喂实芯纯钙线

钙的收得率提高10%

喂线量少50%

喂线时间缩短2～3 min

钢水温降减少3～5℃

具有明显的冶金效果。

Abstract

The metallurgical effects of solid-core calcium wire (99.35% Ca) and CaFe wire (30.53% Ca) feeding during 160 t

230 t and 300 t LF refining process have been compared and analyzed. The average acid soluble aluminium

sulphur content and temperature of liquid before and after feeding solid-core pure calcium are respectively 0.036%

0.010%

1587 ℃ and 0.029%

0.008%

1584 °C. As compared with feeding CaFe wire

with feeding solid-core calcium wire the yield of calcium increases by 10%

the feeding wire amount decreases by 50%

the feeding wire time reduces by 2 ~ 3 min and the temperature drop of liquid decreases by 3 ~5 ℃

it has obvious metallurgical effect.
