平炉用天然富矿日益不足是一普遍问题。用人造富矿代替天然富矿之不足,乃是平炉炼钢发展方向之一。近年来,鞍钢对平炉球团矿的制造与使用曾进行过多次生产性试验,但始终未能得到正常使用。1963年鞍钢缺35%的天然富矿,为解决这个问题,鞍钢以自立更生、奋发图强的精神,于年初开始即进行了一次规模较大、时间较长的生产性试验:用球团矿代替35%的天然富矿用于平炉。共统计分析1896炉资料,并选定1号及3号平炉为重点观察试验炉。同时,为了确定今后生产人造富矿的合理方案,试验了碱度不同、球状不同的五种球团矿。
It is a common problem that the open hearth is becoming increasingly deficient with natural rich ore. Man-made rich ore instead of natural rich ore shortage, but is one of the development direction of open hearth steelmaking. In recent years, Anshan Iron and Steel Furnace flat furnace pellet production and use of many productive trials, but has not been able to get normal use. Anshan Iron and Steel in 1963 lack of 35% of the natural rich ore, to solve this problem, Ansteel in order to self-reliance, work hard to strengthen the spirit of the beginning of the year that is carried out a larger, longer-term productive test: replace pellets with 35% Natural Bonanza used for hearth furnace. A total of 1896 furnaces were statistically analyzed, and the No.1 and No. 3 open hearth furnaces were selected as the key observation furnaces. At the same time, in order to determine the reasonable scheme for producing man-made rich ore in the future, five kinds of pellets with different basicities and different spheres were tested.
