Quality requirements on coke for blast furnaces operating with coal-dust fuel

Analysis of the CSR values of coke corresponding to specific consumption of coal-dust fuel—on the basis of operational data for furnaces in the United States, Canada, Belgium, Germany, France, Italy, Spain, and South Korea—permits the estimation of the mean CSR value of coke required when the coal-dust injection is 120, 130, 150, 180, and 200 kg/t of hot metal. This information is used in the construction of systems based on coal-dust fuel at OAO Severstal, OAO NLMK, OAO NTMK, and OAO ZSMK.
