Influence of Recycled Wastes on Slag Foaming during EAF Steelmaking

Abstract:

The potential converting the end-life product into a renewable source and replaced the conventional material found in iron and steelmaking production next tackled the world’s most problematic waste stream. Generally, integrating the waste material becomes wealth only available to certain wastes industries due to high temperature application. Recycling waste materials were introduced in order to control slag foaming in EAF steelmaking. The present paper reviews about slag foaming behaviour focused on slag droplet volume (V_t/V₀ ratio), their transformation and morphology during carbon/slag interaction using sessile-drop technique at 1550°C on polymeric (HDPE), agricultural waste (palm shell), rubber tyres and metallurgical coke as the potential carbonaceous materials in EAF steelmaking. These results indicate that partial replacement of conventional materials with recycled waste materials is efficient due to improved interactions with EAF slag.
