A high blast temperature is an effective measure that improves pulverized coal injection(PCI)and energy consumption,decreases the cost of blast furnaces(BF).Apart from using technology such as the increased vault temperature of the hot-blast stove,the increased temperature of the waste gas,the preheating of combustion air and gas, and fully closed mixed air valves,other measures,such as using an oxygen-enriched blast stove,burning high heating value converter gas,increasing the number of stove changes to reduce the time needed for stove blasts,were taken to increase the blast temperature of the 2500 m~3 BF in recent years.The blast temperature of the 2500 m~3 BF was continuously increased in these years.The monthly average temperature of the 2500 m~3 BF reached 1158℃,with the highest blast temperature reaching 1195℃in 2006.This technique of increased blast temperatures has reached an advanced level in China.
