Slag processors may handle a variety of materials such as steel slag, ladle slag, pit slag, and used refractory material to recover steel metallics. These materials must be source separated, and well-defined handling practices must be in place to avoid contamination of the steel slag aggregate. The slag processor must also be aware of the general aggregate requirements of the end user.
At the studied Nordic steel plant, two types of iron ore pellet are used in the iron and steel production; one containing about 0.12% V and 0.008% P, the other 0.11% V and 0.025% P. The vanadium from the iron ore is concentrated into the hot metal in the blast furnace process. The vanadium and phosphorus distribution between slag and metal and dependencies in the metallurgical processes are ...
Ground Granulated Blast Furnace Slag (GGBS): The GBS is then ground in a rotating mill comprised of chromium-steel balls which reduces it to fine powder with surface area greater than 400 sqm/kg (finer than cement, which is around 300 sqm/kg) transforming it into GGBS.
Electric arc furnace - Wikipedia. An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc.. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.
Steel slag can be processed into a coarse or fine aggregate material for use in dense- and open-graded hot mix asphalt concrete pavements, (1,2,3) and in cold mix or surface treatment applications. (4) Proper processing of steel slag and special quality-control procedures are extremely important in

Steel Plant Training Course Section II: What is Slag? Basic Steelmaking for Electric Arc Furnaces Page 1 of 25 Introduction: A variety of lime products and blended lime products are used in the production of steel. In the electric arc furnace practice it is common to see high calcium pebble lime, dolomitic pebble lime and iron coated dolomitic pebble lime being charged over the roof in a ...
In addition, the slag from the BOS plant such as converter slag and ladle slag has useful properties once weathered to allow for expansion of the lime-bearing material. EAF slag is a strong and durable material which is highly versatile and ideally suited for use as an aggregate in many applications.

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.
