在使用逆流渣的试验装置上分15次进行了2640分钟的试验,表明渣钢逆流法有极高的精炼效率:能去除99.8％的磷和87％的硫,终点磷可低达0.001％,并能方便地应用气化脱硫反应。同时,还得到了原材料消耗少、热效率高、炉衬侵蚀速度小等效果。计算证明,上述精炼效果尚远未达到理想状态值。因此,本法不仅有助于连续冶炼工艺的发展,而且特别适用于高纯和超纯钢的生产。
In the test device using the countercurrent slag 15 minutes for 2640 minutes of the test showed that the slag countercurrent reflux method has a very high refining efficiency: to remove 99.8% of the phosphorus and 87% of the sulfur, the end point of phosphorus can be as low as 0.001% And can easily apply gasification desulfurization reaction. At the same time, it also has the advantages of less consumption of raw materials, high thermal efficiency and small lining erosion rate. Calculations show that the refining effect is far from reaching the ideal state value. Therefore, this Law not only contributes to the development of continuous smelting process, but also is especially suitable for the production of high-purity and ultra-pure steel.
