Tenova's Consteel® Electric Arc Furnace (EAF) is the efficient steelmaking process where the raw feed materials are heated and charged continuously into an EAF and melted by immersion in the liquid steel present in the furnace, while simultaneously controlling gaseous emissions.. Tenova's Consteel® EAF produces liquid steel with high …

 — In this study, granulated blast-furnace slag was treated by wet grinding to promote its reactivity (i.e. WGGBS), and carbide slag (CS), one kind of industrial wastes, was used as the alkali. CS activating WGGBS system was designed, where the replacement ratio of WGGBS by CS was less than 10%. Mechanical property of this …

Depending on the availability of the raw materials and market-specific requirements, further extenders are added to the common grinding process such as granulated blast-furnace slag. Mainly consisting of lime, silica acid, aluminum oxide, and magnesium oxide, blast-furnace slag is normally processed in granulation plants nowadays.

 — A medieval blacksmith, including a woman artisan, from 'The Romance of Alexander', c. 1340 CE. (via the Bodleian Library) The emergence of blast furnacing in 13 th century Medieval Europe heralded the medieval steel revolution.
