我国锰系铁合金除高炉锰铁外,都是用电炉生产的,其产量约占全国铁合金总产量的50％,耗电量占铁合金工业耗电量的26％,相当于全国发电量的0.5％。因此,研究用省能型工艺生产锰系铁合金,对缓和铁合金用电紧张状况和发展铁合金生产都是有利的。 1.以高炉转炉为主体设备生产锰系铁 合金 近几年来,国内外相继涌现了铁合金用氧气转炉,高炉二步法冶炼优质碳素锰铁和 China’s manganese ferroalloy in addition to blast furnace ferromanganese, are produced by electric furnace, the output accounts for about 50% of the total output of ferroalloy, power consumption accounted for 26% of the ferroalloy industry power consumption, equivalent to 0.5% of the country’s power generation, . Therefore, the study of energy-saving process for the production of manganese-based ferroalloy, ferroalloy mitigation of tension and the development of ferroalloy production are beneficial. 1. To blast furnace as the main equipment for the production of manganese ferroalloy In recent years, at home and abroad have emerged in the iron alloy with oxygen converter, two-stage blast furnace smelting quality carbon ferromanganese and
