PRODUCTION OF SINTERED ORE

摘要

PURPOSE: A process for preparing sintered ores by using micro-pore material to improve quality of sintered ores while improving air permeability during absorption by a large blower after discharging compounding raw materials containing a large quantity of iron ores of various coal dusts is provided, which increases productivity and enables to obtain stable quality of sintered ores. CONSTITUTION: In the process for manufacture of sintered ores by burning sintering compounding raw material containing powdery iron ore, side material and heat source on a sintering pallet truck(106), 1 to 5% by weight of micro-pore material is added to the sintering compounding raw material at a level of 50 to 300mm from the upper part of a sintering layer on the sintering pallet truck.
