一、高碱度烧结矿的意义我省现有的地方铁厂,由于矿山资源条件的关系,基本上都以低品位铁矿为冶炼的主要原料,所以各厂的经济技术指标长期落后(表1)。据统计,(八○年上半年、入炉焦比1000公斤以上的工厂有23家,生铁成本300元以上的有13家)。 First, the significance of high alkalinity sinter The existing iron mills in our province, due to the relationship between mine resource conditions, are basically low-grade iron ore as the main raw material for smelting, so the long-term economic and technical indicators of each plant 1).
