鞍钢从1971年起先后在四座高炉上进行汽化冷却实践.由于汽化冷却是一项新技术,设计、管理和操作都没有成熟经验,相继出现一些问题,特别是1976年投产的6~#高炉汽化冷却效果最差,运行仅一年另七个月,冷却设备就严重损坏,生产两年多被迫停炉中修,造成了很大损失.因此高炉汽化冷却至今没有全面推广.1974年11月9日投产的2~#高炉,汽化冷却运行了近六年时间,产铁314万吨.该炉开炉后就不断强化,到中修停炉前.有效容积利用系数还保持在2.0吨/米~3·日以上,中
Since 1971, Ansteel has carried out vaporization cooling practice on four blast furnaces. Since evaporative cooling is a new technology, there is no mature experience in design, management and operation, and some problems have appeared successively, in particular the 6 ~ # blast furnace gasification put into operation in 1976 Cooling effect is the worst, only one year running another seven months, the cooling equipment is severely damaged, production was forced to shut down more than two years of repair, resulting in a great loss, so the blast furnace gasification cooling has not fully promoted. On the 9th, 2 ~ # blast furnaces were put into operation, and the gasification and cooling operation lasted for nearly six years, producing 3.14 million tons of iron, which was strengthened continuously after being fired, and the effective volumetric utilization factor remained at 2.0 tons / Rice ~ 3 · day or more, in
