| 摘 要： | 阐述了武钢一炼钢通过开发完善钢包吹氩工艺，从而在吹氩站实施造渣、调渣、钙处理及温度控制等原来由LF所完成的精炼过程；并将其应用在部分冷墩钢的实际生产中，在获得好的钢水浇铸性能的同时，还降低了生产成本。分析结果表明，采用优化的吹氩工艺生产冷墩钢的熔渣渣况和钢中夹杂物的控制与原LF工艺生产的基本一致，甚至略优于原工艺。

| Abstract: | The present paper introduces the development and improvisation of the overall process of argon blowing in the NO. 1 Steel-making Plant of WISCO, in which the refining processes including slag-formation, slag modification, Ca-treatment and temperature regulation originally carried out in LF are currently accomplished in the Argon Blowing Station. Very satisfactory castability has been achieved and the production cost remarkably cut down in application of the new technology. Analytical results show that the slag melting and inclusion control in steel in refining the cold heading steel by application of the optimized argon blow technology are similar to and even superior over the original LF process. |
