Abstract

To meet the demand for production increase, high productivity operation has been carried out based on the following targets at Chiba No. 4 Sinter Plant :
(1)Maintenance of high bed height operation by ensuring and stabilizing permeability of sinter bed.
(2) Achievement of high productivity and sinter production cost saving through improvement of sinter yield.
(3)Maintenance of low SiO2 operation under high productivity operation.
From application of coutermeasures for targets above mentioned, the following results were obtained :
(1)A high productivity operation of 1.8 t/hm2 without adding any binder was obtained.
(2)The total amount of return fine has been decreased from 400450 kg/t-s to 260300 kg/t-s.
(3) Sinter production cost has been decreased and cost minimum point has shifted to high productivity side.
