The high blast temperature of blast furnace is to improve the stability of reducing coke rate and improve the direct measures of coal injection and stability of blast furnace utilization coefficient. 1200~1300 temperature is an important symbol of modern blast furnace in twenty-first Century. Wind temperature of blast furnaces in China wanders for a long time in 1050~1150, in recent years, wind temperature although improved, but compared with foreign countries, is still in the lower level of wind temperature, the wind temperature condition has become further improve the pulverized coal injection rate, improve the major obstacle for the index of blast furnace. Therefore, it is urgent and necessary to raise the temperature of blast furnace. Large blast furnace staggered parallel heat air automatic control technology is an international leading level of automation control technology, the does not change in the hot air furnace combustion conditions, improve the air temperature of 50 (No. 5 BF in WISCO), greatly reduce the consumption of coke, can greatly reduce production cost, the enormous economic benefits.
