Advanced technology and application of large-scale CDQ
JP Steel Plantech Co. constructed 200 t/h and 185t/h large-scale CDQs, through technological improvements and scaling up of the CDQ facility, which was introduced from the former Soviet Union in 1972. Up to now, these CDQs have kept up a yearly operating ratio of 95% even after operation for 25 years, and 18 years respectively. In order to achieve these high operating ratios, I introduce the facilities technology which makes these factors realizable and which need to be taken into consideration.

Advanced technology and application of large-scale CDQ
After it operates, the former maintains both high utilization rates of 95% to large-scale CDQ of 200t/h and 185t/h that our company constructed with the calendar day base though the latter has passed 15 years for 22 years. The boiler is maintained in these CDQ, and moreover, it accompanies, they are made to generate electricity, and the utilized capacity for power generation also maintains 95%. It introduces the factor and the equipment technology to achieve these high utilization rates and availability.

Maximizing Sintering Plant Heat Recovery
There is WHRS that collects the rejection heat generated when the baked high temperature sintering ore is cooled in CDQ and the sintering equipment to collect the rejection heat generated when scorching coke is cooled in TRT and the coking furnace using the blast furnace top pressure and the temperature of exhaust gas by steam/electric power by steam/electric power in the blast furnace as a waste heat recovery technology of exhaust gas in the pig iron making process. This paper introduces the waste heat recovery technology of the sintering equipment and the effect.
