最近20年,高炉普遍喷吹重油,一是经济上合算,二是喷油对发展高风温、富氧和脱湿鼓风技术有利.随着油价不断上涨,最近报导了无油操作的大量试验.为此索尔梅2号高炉(有效容积2185米~3)于1980年4月作了一个月的全焦操作试验.同年8月底开始正式转入全焦工业性操作.由于为配合全焦操作所作的研究工作以及炉料质量的改善,高炉自1980年10月以来获得了全焦操作的极好成绩:最好月份平均利用系数
In the recent 20 years, blast furnaces generally blow heavy oil, one economically advantageous, and second, fuel injection is beneficial for developing high wind temperatures, oxygen enrichment and dehumidification blasting techniques. As oil prices continue to rise, a large number of oil-free operations have recently been reported Test.Therefore, the Somer 2 blast furnace (effective volume of 2185 m ~ 3) made a full-scale operation test in April 1980. In the same year the end of August officially transferred to full coke industrial operation. The work done by the coke operation and the improvement of the quality of the charge resulted in an excellent result for the all-coke operation since October 1980: the best monthly average utilization factor
