吹氩可以净化钢质。顶吹氩优于底吹氩。沸腾钢和一般镇静钢采用吹氮代替吹氩,将显著提高钢的质量。喷吹硅钙粉2公斤/吨,脱硫效率一般达70～90％,[O]在20ppm以下时,[S]可以脱到小于0.005％。喷入熔剂量为3.5～6公斤/吨,脱硫效率达70～95％,在渣指数为0.35时脱硫能力最高。吹氩造渣脱硫法对减少钢水中Al_2O_3等夹杂有良好的效果。喷粉的主要作用在于脱硫和控制钢中夹杂形态,对改进一些重要用途钢种的性能和质量具有重要意义。
Argon can purify the steel. Top blowing argon is better than bottom blowing argon. Boiling steel and the general use of nitrogen blowing instead of blowing nitrogen blowing, will significantly improve the quality of steel. Blowing 2 kg / ton calcium silicate powder, desulfurization efficiency is generally 70 to 90%, [O] below 20ppm, [S] can be off to less than 0.005%. The amount of flux injected is 3.5 ~ 6 kg / t, desulfurization efficiency of 70 ~ 95%, slag index of 0.35 when the desulfurization capacity of the highest. Argon blowing slag desulfurization method to reduce the inclusion of Al 2 O 3 in molten steel has a good effect. The main role of dusting is the desulfurization and control of inclusions in steel, to improve the performance and quality of some important uses of steel is of great significance.
