我厂在实际装入量为4.5吨的CG—3型3吨电炉上,使用二级高铝砖(含Al_2O_370％,荷重软化点1498℃)砌炉盖,并用粘土砖砌电极孔,由于砖质量较差炉盖寿命一直不高,1962年平均为44.8炉,1963年平均为44炉,为了解决这个问题,我们观察分析了许多次炉盖的侵蚀形状,经过研究,于1964年一季度采用了两项措施后,炉盖寿命大有提高,1964年平均寿命达191次,而其下半年已稳定在225次以上,1965年元月份又跃进到256次,这样给提
I plant in the actual loading of 4.5 tons of CG-3-type 3-ton electric furnace, the use of two high-alumina brick (containing Al 2 O 3 70%, load softening point 1498 ℃) built furnace cover, and with clay brick electrode hole, The poor quality of the lid life has not been high, an average of 44.8 furnaces in 1962, an average of 44 furnaces in 1963, in order to solve this problem, we observed and analyzed many erosion patterns of furnace cover, after research, adopted in the first quarter of 1964 After two measures, the life span of the furnace cover greatly increased, reaching an average of 191 times in 1964, while its stability in the second half of the year was more than 225 times. In January 1965, it leapt to 256 times again,
