近年来,我国高炉炼铁事业,经历了一次又一次的技术革命,发展非常迅速,唯高炉的炉顶设备方面改进缓慢,与当前高炉冶炼高速发展形势不相适应,需要探索改进。目前双钟式设备,炉顶结构庞大复杂,维修困难。如炉口平台以上的高度,几乎等于炉底到炉口的高度,容积1000米。高炉炉顶设备重量约180吨(还不包括金属结构
In recent years, China’s blast furnace ironmaking business has undergone a technological revolution again and again, developing very rapidly. The improvement of blast furnace top furnace equipment is not compatible with the current situation of blast furnace smelting and rapid development. It needs to be explored and improved. At present, dual-bell equipment, large and complex roof structure, maintenance difficulties. Such as the mouth above the platform height, almost equal to the furnace floor to the height of the mouth, the volume of 1000 meters. Blast furnace top equipment weighs about 180 tons (not including the metal structure
