Electric arc furnace carbon steel slag is a by-product of the manufacture of steel by the electric arc furnace process (EAF). Production and Processing An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current.
blast furnace slag accounted for about 60% of the tonnage sold and was worth about $290 million; about 85% of this value was granulated slag. Steel slag, produced from basic oxygen and electric arc furnaces2 accounted for the remainder. There were 29 slag-processing companies servicing iron and/or steel companies or reprocessing old slag
Electric arc furnace slag is a byproduct of the production of steel in an electric arc furnace. In electric arc furnaces the charge materials (scrap iron and steel) are loaded into the furnace and directly exposed to electric terminals. The current passing through the terminals creates an electric arc that melts the charge materials.
