Types of slag

Slag is a valuable resource for any steelmaker. Steelmakers sell blast furnace slag to the cement industry.

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; it is highly versatile and ideally suited for many applications use as an aggregate.

The slag derived from stainless steel production presents particular challenges, it is owing to the handling of fines in its cooled state. Our great wall group will process Electric Arc Furnace (EAF) and Argon-Oxygen Decarburization (AOD) slag, from austenitic or ferritic grades of stainless steel. Great wall also has solutions for complying with the most environmental regulations; it requires additional precautions when handling stainless slag owing to the risk of airborne dust emissions.

The steelmaker benefits from slag recycling by avoiding the cost of landfill. Slag is a man-made mineral; therefore its use as an aggregate in place of a natural aggregate product avoids the environmental footprint from quarrying.
