IMPROVEMENT OF MICRO-NEGATIVE PRESSURE IGNITION FOR ANGANG SINTERING MACHINE
Sintering micro-negative pressure ignition can ensure the depth of the ignition layer and effectively reduce gas consumption.In addition,micro-negative pressure in the ignition section can maintain the initial permeability of the material layer,reduce the compaction degree of the material layer,improve the permeability of the material layer during the sintering process,which is beneficial for low-temperature sintering,the development of calcium ferrite,and the improvement of high-temperature reduction performance of sintered ore.This plays a promoting role in the smooth operation of blast furnaces.
