when is slag produced
Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces.The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.igure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant. The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag.
