The Practice of Strengthening Pulverized Coal Injection

Abstract:

The research to increase injecting amount into blast furnace was carried out on the basis of the actual production of Longmen Steel Co., Ltd.. This paper starts with the study of pulverized coal properties of the blast furnace, combined with the experimental researches such as explosibility study of pulverized coal, the study of the effect of adding additives on combustion properties of Pulverized Coal, the factors affecting the amount of injection coal of Blast Furnace in Longmen Steel Co., Ltd. were identified and the specific measures to improve coal ratio and reduce the coke ratio were put forward by theoretical analysis and experimental research as well as practical production.
