iron slag recycle

The recycling and reuse of steelmaking slags — A review

Slag is a mainly non-metallic by-product that is made up of silicates, alumina silicates, calcium aluminum silicates, and iron oxides (Joulazadeh and Joulazadeh, 2010) During the BOS process a proportion of the molten iron cannot be recovered so elemental iron is often observed in the slag (Yildirim and Prezzi, 2011) Slags can be classified.

slag

Basic Oxygen Furnace Steel Slag (BOF or Steel Furnace Slag) This slag Is formed when molten Iron, scrap metals and various fluxes, such as lime, are oxidized by injecting large amounts of pure oxygen into the molten iron mix to create molten steel and molten slag Slow cooling of the molten slag produces a dense rock material Principal uses.

Slag: From By-product to Valuable Construction Material

Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse.

Creating Iron

If you want to do anything with it, you have three options First, you can melt it, mix it with slag and hammer it out to eliminate most of the carbon (down to 03 percent) and create strong, malleable wrought iron The second option is to melt the pig iron and combine it with scrap iron, smelt out impurities and add alloys to form cast iron.
