由于原燃料质量差,操作制度不合理,酒钢2号高炉长期炉况不顺,技术经济指标较差。1996年后,通过加强精料工作,采用合理的装料制度和送风制度,加强中部调剂,合理控制喷煤量等措施,并坚持采用钒钛矿护炉,在入炉品位只有50％左右和炉役进入后期的情况下,成功地实现了高炉的强化冶炼,高炉各项技术指标得到改善,利用系数达到2.364,焦比降到551 kg/t,煤比达70.81 kg/t。 Due to the poor quality of raw fuel and unreasonable operation system, the long-term furnace condition of Jiuquan Iron & Steel No. 2 blast furnace is not smooth and the technical and economic indexes are poor. After 1996, by strengthening the work of fine materials, using a reasonable charging system and air supply system, strengthening the central adjustment, controlling the amount of coal injection and other measures, and insisting on the use of vanadium-titanium ore retaining furnace, only about 50% And the furnace entered the later stage, the blast furnace strengthened smelting was successfully achieved. Various technical indexes of the blast furnace were improved. The utilization factor reached 2.364, the coke ratio dropped to 551 kg / t and the coal ratio reached 70.81 kg / t.
