Steel Slag - Material Description - User Guidelines for ...
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.
Steel Slag Aggregate - NSL CHEMICALS
Steel Slag Aggregate Steel slag is a by-product formed during the steel manufacturing process. It is a non-metallic ceramic material formed from the reaction of flux such as calcium oxide with the inorganic non-metallic components present in the steel scrap.
Steel Slag - an overview | ScienceDirect Topics
Steel slag is an industrial byproduct obtained from the steel manufacturing industry. It is produced in large quantities during steel-making operations that use electric arc furnaces. Steel slag can also be produced by smelting iron ore in a basic oxygen furnace.

Special quality-control procedures are needed during steel slag production (at the steel-making plant) and during aggregate processing to ensure that steelworks "rubbish" (furnace brick, wood, incompletely fused fragments, lime, rock, etc.) is not included as part of the steel slag aggregate.
FACT SHEET Steel industry co-products
plants often use a mix of DRI and recycled steel feeds. On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of co-products. These include slags, dusts, sludges and other materials. Ironmaking and steelmaking slags More than 400 million tonnes of iron and steel slag is produced each year.

Generation of iron and steel slag : NIPPON SLAG ASSOCIATION
Steelmaking slag is generated by the process that turns pig iron produced by a blast furnace into tough and highly workable steel. Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components from the pig iron and refine it to produce strong steel.
