Slag From Byproduct to Valuable Construction Material

Slag From Byproduct To Valuable Construction Material

Jul 29, 2014 Slag is a by-product of the metallurgical smelting process. Slag has a double role it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.

Electric Arc Furnace Carbon Steel Slag Eaf

Production and Processing. An Electric arc furnace EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added as flux combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.

Jun 29, 2017 Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers current waste footprint.
