大型平炉双槽出钢的挡渣技术

SLAG RETAINING TECHNIQUE FOR LARGE OPEN HEARTH WITH DUAL TAPPING SPOUTS

高氧化性炉渣进入钢中,不但抑制钢包精炼的脱S反应,而且大大增加了钢中氧化物夹杂。本文介绍包钢对大型固定式双槽出钢平炉进行了挡渣技术的试验、研究及取得的显著效果。

The entrapment of high oxide slags in the liquid steel will not only check the desulphurization behavior in the ladle refining but also greatly increase the oxide inclusions in steel. Trials are conducted on the slag retaining technique in the large open hearth with dual tapping spouts at Baotou Iron &Steel Company and marked results have been achieved in the tests.
