Abstract Scope |
Smelting reduction ironmaking process can use non coke coal powder and iron ore powder to smelt hot metal. It has the advantages of short process flow, less production investment and low energy consumption. It is a cutting-edge ironmaking technology in contemporary iron and steel industry. In this paper, the "upper space" combustion model of iron bath smelting reduction furnace is established by using numerical simulation method. the effects of different top oxygen lance position and oxygen enriched flow inlet angle on the combustion characteristics of furnace are studied. The temperature of flame increases with the increase of top lance position; With the increase of oxygen enriched gas flow rate, the temperature of combustion flame decreases. When oxygen enriched gas flow rate is 0.2kg/s, the temperature of upper space of furnace is the highest; The oxygen lance inlet angle is 10° The temperature increases from the furnace wall to the furnace. |
