Title: Blast furnace operation method
Inventor: IIZUKA MOTOHIKO
IPC: C21B5/06
Filed: 1979-10-08
Abstract: PURPOSE: To execute effective production reduction by mixing a blast furnace gas into the blast air to the blast furnace in the reducing operation for production of the blast furnace.  
     CONSTITUTION: In the reducing operation for production, the blast air mixed with a blast furnace gas is blown into the blast furnace before the blast air is blown into a hot stove. For example, in case 1% of the entire part of the blast furnace gas is mixed, the volume of the mixed blast air at the blast furnace tuyere ends becomes 1.0003 times that of ordinary blast air. To equalize the heat balance in the lower part of the blast furnace 1.0111 times of mixed blast air is necessary. If themixed blast air is used and the furnace is operated by blowing the same blast flow rate as that in the prior art, the pig iron production is decreased by 1.1% from the formula. In the case of all coke operation, the effective operation is performed by lowering coke ratio.
