Abstract
To meet the demand for increased production, higher productivity has been carried out based on the following targets at Chiba No. 4 Sinter Plant of Kawasaki Steel Corp.:1) Maintenance of high bed height operation by ensuring stable permeability in the sinter bed, 2) Cost saving sinter production through improvement of sinter yield, and3) Maintenance of low SiO2 operation.The following results were obtained from the implementation of various countermeasures.(1) A highly productive operation of 1.8 t/hm2 without adding any binders.(2) The total amount of return fine has been decreased from 400–450 to 260–300 kg/t-sinter.(3) Sinter production cost has been decreased and the minimum cost per unit has shifted to a higher output.
