Improvement of Production by Decreasing Air Leak at Nagoya No. 3 Sintering Plant

Abstract

Air leak repairs were carried out to increase a production rate at the No. 3 sintering plant in Nagoya Works of Nippon Steel. 83 vol% of air leaks were found to be localized on pallet trucks and dead plates based on oxygen concentration measurement. Through deliberate repairs of such leakage, the sinter production rate was increased by 5 mass%.
