【摘要】 本文报导了钢中喂线法新工艺的试验结果,在100 kW中频感应炉进行脱硫与脱氧,改变钢中夹杂物及工艺的研究。结果表明,Ca-Si线喂入最1.5～3.5 kg/t,平均脱硫率61.8 ％。最高脱硫率达到91 ％。钢中硫含量可降到O.002 ％。 同时取得了脱氧和改变钢中夹杂物的良好效果, 钙的收得率可达到27 ％。更多还原

【Abstract】 The experimental results of wire feeding into steel is reported in this paper. Desulphurization, deoxidation and inclussion modification were studied with a 100 kW HF furnace. The results show that, at a feeding rate of 1.5-3.5 kg/t, the average desulphurization ratio is 61.8 %. The maximum ratio reaches 91 %, and the minimum sulphur content can be reduced to 0.002 %. Deoxidation and inclusion modification are observed simultaneously, the yield of calcium can reach 27 %.更多还原
