Abstract:The main characteristics of ironmaking in China are high costs of the hot metal and the low circulation utilization rate of the solid waste resources. For instance,the coke dry quenching dust,which was produced in the coking process,has not utilized effectively for a long period. Thus,the injection of coke dry quenching dust in blast furnace not only could reduce the smelting costs,but also could relief the short of the anthracite and benefits to the environment protection. The technical feasibility to use the coke dry quenching dust replace some high cost anthracite was analyzed by analyzing the burnout rate,grinding performance and coal ignition point,while the industry experiments were conducted in the blast furnace in Jiusteel. In addition,some measurements for injecting the coke dry quenching dust were proposed. The study could contribute to reduce the costs of hot metal,improve the utilization of waste resources as well as the energy conservation and emission reduction.
