我厂于1984年下半年开始使用进口锰矿,1985年进口矿用量占总用量的11.21％,年产量比1984年增加18955吨,入炉焦比降低115公斤/吨。为了了解其使用效果,据实际生产资料分析如下:一、块矿使用效果: 在生产条件基本相似情况下,(诸如:大气湿度、熟料比、生产水平等),使用一定配比进口矿块的效果。选择1984年3月份与1985同期加以比较。
I plant began to use imported manganese ore in the second half of 1984, imported ore in 1985 accounted for 11.21% of the total amount, the annual output increased 18,955 tons than in 1984, into the furnace coke ratio decreased by 115 kg / ton. In order to understand the effect of its use, according to the actual production data analysis as follows: First, the use of lump ore results: Under similar production conditions (such as: atmospheric humidity, clinker ratio, production level, etc.), the use of a certain ratio of imported ore Effect. Select March 1984 to be compared with 1985 over the same period.
