一、前言1980年全国各类铁合金产量为99.2万吨。估计耗电49亿度,占全国当年用电量的2%左右。其中,75%硅铁占整个铁合金产量的30%,能耗占60%左右。所以,研究硅铁合金用焦,更有实际意义。目前,我国硅铁合金生产所用炭质还原剂大多为冶金焦。因其反应性能差,比电阻
I. Preface In 1980, the output of various types of ferroalloy in China was 992,000 tons. The estimated power consumption is 4.9 billion kilowatt hours, accounting for about 2% of the national electricity consumption in the same year. Among them, 75% ferrosilicon accounts for 30% of the total ferroalloy output, and its energy consumption accounts for about 60%. Therefore, the study of ferrosilicon alloy coke, more practical significance. At present, most of the carbonaceous reducing agents used in the production of ferrosilicon alloy are metallurgical coke. Because of its poor response, specific resistance
