日本文献称“控制炉料分布”与“控制炉缸温度与送风”为炉内控制技术.炉缸温度主要由风口理论燃烧温度与铁水温度反映出来.七十年代,日本高炉风口理论燃烧温度与铁水温度均有所提高.武钢三号高炉采用炉内控制技术,煤气利用大改善,CO_2提高到18%,CO/(CO+CO_2)提高到0.481,焦比降低到477.4公斤,综合燃料比降低到537.1公斤.
Japanese literature said “control of charge distribution” and “control of furnace temperature and air supply” for the furnace control technology.The furnace temperature is mainly reflected by the tuyere theory of combustion temperature and the temperature of molten iron.Seventies, Japan blast furnace tuyere The theoretical combustion temperature and the hot metal temperature all increased.The WISCO No.3 blast furnace adopted the furnace control technology, the gas utilization was greatly improved, the CO 2 increased to 18%, the CO / (CO + CO 2) increased to 0.481 and the coke ratio decreased to 477.4 kg, The overall fuel ratio was reduced to 537.1 kg.
