PRODUCTION, CHARACTERISTICS AND USE OF …

The ferroalloy separation from the lumpy slag happens in a special process, which is based on a gravity and magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 4 and 22 mm. Coarser fractio ns are handled by a heavy media separation - the DWP-method. A magnet

Electric arc furnace slag

Electric arc furnace slag. Electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace (EAF) process.In this process steel scrap with additions of fluxes (e.g., lime[stone] and/or dolomite) are heated to a liquid state by means of an electric current.

Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron. ... Electric arc furnace slag

Properties

The content of iron (Fe) in blast furnace slag (ABS/GBS) is usually lower than 0.5 wt. % since it results from a reduction process. In contrast to blast furnace slag, basic oxygen furnace slag (BOS) and electric arc furnace (EAF) slag (steel slags) are generated in an oxidizing process and therefore have iron contents that are significantly higher.
