摘要
A method of improving the productivity of the sintering machine by air injection at a specified location, preferably where combustion zone thickness is high such that this increases the air filtration velocity. The selective location of air injection during the sintering process, reduces the combustion zone thickness at the sinter discharge end (SDH) and increase the hot zone permeability for high FeO sintering operation and thereby favouring elimination of the resistance offered by the high temperature zone. Air is injected from the top of the sinter bed from a hood (AIH) in the location 65-80% of the length of the machine from raw mix charging hopper (RMH) side. Sintering proceeds from top surface to the bottom of the bed. The extension of hot zone width is restricted by the fabricated hood. Air injection from top through the hood enhances the rate of reaction and sintering speed, favoring improvement in productivity of the sintering machine. Specific productivity of sintering machine is increased from existing 1.20 to 1.28 t/m2/hr.[IN-KOL-2007-00318A]
