摘要/Abstract

摘要： 建立了底吹喷吹石灰石粉的冷态模型:用水模拟钢水，用浸盐的空心Al2O3模拟石灰石粉，用真空泵油模拟炉渣，研究了复吹转炉底吹喷粉的重要参数粉剂分布和粉剂穿透比.考察了不同底吹布置条件下的粉剂分布，利用图像处理法确定了最佳的底吹布置方式.在最佳底吹布置方式条件下，考察了不同固气比和粉剂粒度对粉剂穿透比的影响；结果表明穿透比随固气比和粉剂粒度的增加而增加，确定了实验条件下最佳固气比为30~40，粉剂粒度为0212~0380mm.

关键词: 转炉, 底吹喷粉, 粉剂分布, 粉剂穿透比, 固气比, 粉剂粒度

Abstract: A cold model of top and bottom blown converter with bottom powder injection was established to investigate the powder distribution and penetration ratio in melt bath. Water， saltcoated hollow alumina particles and vacuumpump oil were used to simulate liquid steel， limestone powder and slag， respectively. The powder distribution under different bottom blowing arrangements was studied by using the image processing method to find out the optimum bottom tuyere arrangement. With the optimum bottom tuyere arrangement， the effects of solid/gas ratio and powder particle size on powder penetration ratio were studied. The results show that the powder penetration ratio increases with the increase of solid/gas ratio and powder particle size. Under the laboratory conditions， the solid/gas ratio of 30~40 and the powder particle size 0212~0380 mm are suggested.

Key words: steelmaking converter, bottom powder injection, powder distribution, powder penetration ratio, solid/gas ratio, powder particle size
