Title:
METHOD FOR PRODUCING SINTERED ORE
Document Type and Number:
Japanese Patent JP2021042436
Kind Code:
A
Abstract:
To achieve high yield even with a high content of pisolite ore in raw material for sintering.SOLUTION: The present invention relates to a sintered ore production method that produces sintered ore by blending pisolite iron ore at a rate of over 50 mass% to all the iron ore in raw material for sintering. In order that the rate (Wp) of pisolite iron ore to all the iron ore and the coke segregation (dC) meet the relation of "dC=-0.02 Wp+2.0±0.2 Wp", the raw material for sintering is charged into a sintering machine.SELECTED DRAWING: Figure 3
