重庆巴县白市驿铁厂自七○年以来,矿山采矿和矿石准备处理过程中产生大量粉矿(约占矿石产量的27％,其中含有5％左右的固定炭),近几年来曾采用平地吹生产自然碱度烧结矿。但这种烧结矿氧化亚铁一般大于30％,最高达49％,高炉配用量最多只能使用15％,因此矿粉有增无减,堆积如山。而熔剂单耗和焦比分别高达1.122吨和1150公斤。 Since 1978, a large number of fines have been produced during the preparation and processing of mines and mines (accounting for about 27% of the ore production, which contains about 5% of fixed charcoal) and has been used in recent years Flat ground production of natural alkalinity sinter. However, the sinter iron oxide is generally greater than 30%, up to 49%, the blast furnace with the amount can only use up to 15%, so the flour mines unabated, pile up. The flux consumption and coke ratio were as high as 1.122 tons and 1150 kg.
