我厂有一座28m~3小高炉,承担冶炼锰铁生产任务。随着冶炼强度的逐渐提高,每天炉料入炉量达200吨左右,工作量很大。原料是高炉生产的基础,如何认真对待入炉原料的处理,对冶炼水平关系极大。我厂炼锰铁时间虽不长,但也深感“精料、大风、高温”是小高炉冶炼锰铁的高产经验。我厂冶炼水平七五年比七四年好,七六年又比七五年好(主要经济指标见表),除了高炉操作水平的提高,风电机等设备的相应增加以外,入炉原料、燃料的认真处理有很大作用。
I plant a 28m ~ 3 small blast furnace, assume the task of smelting ferromanganese production. With the gradual improvement of smelting strength, the daily charge of the furnace up to 200 tons, a heavy workload. Raw materials are the basis of blast furnace production, how to deal with raw materials into the furnace seriously, the relationship between the level of smelting great. Although not long time for refining ferromanganese plant, but also deeply “concentrate, gale, high temperature” is a small blast furnace ferromanganese production experience. The level of smelting in our factory is better than 74 in 1975, 756 more than in 1975 (the main economic indicators are shown in the table). In addition to the increase of blast furnace operation level and the corresponding increase of wind turbines and other equipment, Serious fuel handling has a big role.
