Primary Mill Fabrication A gener Al di AgrAm for the production of steel from raw materials to finished mill products is shown in Fig. 1. Steel production starts with the reduction of ore in a blast furnace into pig iron. Because pig iron is rather impure and contains carbon in the range of 3 to 4.5 wt%, it must be further refined in either a basic oxygen or an electric arc furnace to produce ...

Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat's flow-shaping contour, enables recirculation patterns that extend into the furnace. Burners are typically located on the front wall or both the front and rear walls, which is typically referred to as opposed firing
