A PROCESS FOR FASTER SINTERING OF IRON-ORE AND SYSTEM / APPARATUS TO CARRY OUT SUCH PROCESS

摘要

A faster process of sintering and improving quality of sinter product and a system apparatus/ to carryout such process. More particularly, the process is directed to faster iron ore sintering process that would improve sinter quality in terms of sinter strength, reduction degradation index (RDI) decreased from existing 33.1 to 23.3, increased air filtration velocity due to increased permeability, increased heat capacity of ambient air by preferred injection of steam at selective pressure and controlled quantity over desired region of bed length, humidity adjusted to about 80gm/Nm3, decrease in sinter fines in sinter product. Importantly, the process and apparatus is adapted to reduce the coke rate and the carbon monoxide emission in sinter exhaust gases and also reducing exhauster power consumption by about 5%. A solenoid valve interlocking with sinter machine drive , stops steam supply when the machine is stopped. The present process and system thereof to carry out the process, is therefore adapted to improve quality with reduced RDI and higher reducibility of sinter in a faster way, having wide industrial application in steel plants.
