Title: Operation method of blast furnace
Inventor: IWAI YUKI
IPC: C21B7/24
Filed: 2019-12-06
Abstract: To provide a blast furnace operation method capable of suppressing variation in gas flow distribution in a blast furnace by adjusting a bell-less pattern according to a change in grain size of a raw material.SOLUTION: In a bell-less blast furnace, coke and ore are alternately charged into the furnace by means of a revolving chute placed on top of the furnace. The grain size of either or both of coke and ore is measured by using an on-line grain-size measurement instrument installed in a conveying path to a furnace top bunker of the blast furnace. A mathematical model automatically incorporates the measured grain size and the bell-less pattern at that time. By using the mathematical model, the piling geometry and radial gas flow distribution in the blast furnace are predicted. The distribution of the charged materials is adjusted to suppress fluctuations in the gas flow distribution due to the change in grain size of the charged materials.SELECTED DRAWING: Figure 2
