柳钢 4座高炉自 2 0 0 1年 3月下旬以来 ,全部采用高碱度烧结矿配用 15 %左右的巴西球团矿生产。高碱度烧结矿的优良冶金性能和酸性球团矿的品位高、还原性好、有害杂质少等一系列优点均得到充分发挥。高炉冶炼的各项技术经济指标显著改善 ,由于降低焦比 ,铁水产量增加 ,柳钢高 Liuzhou Iron and Steel 4 blast furnace since late March 2001, all using high alkalinity sinter with about 15% of Brazil pellet production. High basicity sinter excellent metallurgical properties and acidic pellets of high grade, good reducibility, less harmful impurities and a series of advantages have been brought into full play. The various technical and economic indicators of blast furnace smelting significantly improved due to lower coke ratio, increased production of hot metal, Liu Gang high
