提高包钢高炉渣排碱能力的试验研究

Experimental investigation on improving the capacity of removing alkali metals of Baogang blast furnace slag

配制了变碱度、变SiO2 、变MgO系列合成渣试样 ,在 145 0℃高温下 ,测定了碱金属在炉渣中达到饱和时的质量分数 结果表明 ,降低碱度 ,增加渣中自由SiO2 的质量分数 ,增加渣中MgO的质量分数 。

Complex slag samples were confected which included changing basicity,silicon dioxide and magnesia series.The mass percent of alkali metals was determined when it was saturated in the slag at 1 450 ℃.The results indicate that decreasing the basicity or increasing mass percent of free silicon dioxide or increasing mass percent of magnesia in the slag could improve the capacity of removing alkali metals of BF slag.
