随着我国钢铁工业的迅猛发展,炼钢生产需要更多的锰铁。几年来,我厂在255立米锰铁和生铁高炉生产中,使用石灰代替石灰石做熔剂,使炼铁焦比大幅度下降,产量显著提高。为了给高炉提供优质价廉的冶金石灰,增产更多的锰铁和生铁,遵照毛主席关于“综合 With the rapid development of China’s steel industry, steelmaking needs more ferromanganese. Over the past few years, I plant in 255 cubic meters of ferromanganese and pig iron blast furnace production, the use of lime instead of limestone flux, the iron-making coke ratio dropped significantly, the output increased significantly. In order to provide high-quality low-cost blast furnace metallurgical lime, increase production of more ferromanganese and pig iron, in accordance with Chairman Mao on the ”comprehensive
