Furnaces (BOF) plants relying mainly on primary raw materials. “Such distortions cannot last longer if we are serious about climate change and want to move towards a circular economy, in particular as Europe is resource-rich when it comes to steel scrap, which is not the case for iron ore”, Burnand commented.

Recycling and environmental issues of metallurgical slags

2004-1-18 · steelmaking slags are volume-stability and leaching of heavy metals such as Cr and V. The high free CaO leads to hydration and causes cracking in structures8. The stress leads to aggregate deterioration and ultimately pavement failure. Thus reuse of steelmaking slag as a high-quality asphalt aggregate is hampered by the hydration of free lime.

The Basic Oxygen Steelmaking (BOS) Process – …

A 250 ton BOF today needs about 20 tons of pure oxygen every 40 minutes. Despite its high cost, oxygen was used in Europe to a limited extent in the 1930’s to enrich the air blast for blast furnaces and Thomas converters. It was also used in the U.S for scarfing, and welding.
