| 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%,1 587℃and 0.029%,0.008%,1 584℃.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. |
