摘要
为防止氮等离子体弧加热钢液而引起的钢液吸氮,用100kW直流等离子体炉研究了TixO-B2O3-Na2O系保护渣对钢液吸氮的影响。结果表明,保护渣尤其是渣中的TixO及B2O3能有效地减缓氮等离子体弧作用下钢液吸氮。另外还对熔渣的作用及成分的选择作了热力学及动力学分析,所得参数对保护渣的选择有一定意义。
In order to restrict the nitrogen absorption, the test was carried out by using DC nitrogen plasma torch (100 kW) and Ti xO B 2O 3 Na 2O system slag as protecting media. The results showed that the slag is effective to provent nitrogen pickup. Thermodynamic analysis and principle of selecting protecting slag are given.
