本试验有关提高碱性转炉炉衬寿命的一些基础问题。确定了镁砂和白云石的颗粒配比;确定白云石受风化作用,存放时间一般不宜超过5～6天;在原料与沥青的混拌过程中,应先将粗颗粒与沥青结合剂混拌,待拌匀后再加上细粒;机压成型砖较一般压缩空气捣固机所冲制的为优。此外又本着炉衬中残留碳的增加,试验了增碳剂,并在以下几方面进行了试验:改善烘炉方法,提高风眼材料的耐崩裂性,使用铝镁尖晶石砖等。
This test is to improve some of the basic problems of the life of the basic converter lining. Determine the proportion of magnesia and dolomite particles; determine dolomite by weathering, storage time is generally not more than 5 to 6 days; in the mixing process of raw materials and asphalt, the coarse particles should be mixed with the asphalt binder , To be mixed with fine particles to be mixed; machine pressure forming brick stamping machine than the general compressed air for the excellent. In addition, based on the increase of residual carbon in the lining, the carburizing agent was tested and tested in the following aspects: improving the oven method, improving the chipping resistance of the eyelet material, and using aluminum magnesium spinel brick.
