Recycling Rubber Tyres and Waste Plastics in EAF Steelmaking
Steel Research International, 2011AbstractElectric Arc Furnace (EAF) steelmaking uses different carbon based materials as foaming agents. Depending on cost and availability, anthracite and metallurgical coke are among the conventional injecting materials. Considering the energy and green house gas emissions requirements, alternative carbon sources are put on the spot to replace, at ...

Mill Scale - Biomass Pellet as a Charged Material for EAF Steelmaking
Key Engineering Materials, 2023With an aim to utilize the local-based waste materials, this research investigated the production of mill scale - biomass pellet (MBP) as an alternative charged material for EAF steelmaking. Rubber tree bark (RTB) is one of the major biomasses in Thailand, consisting of carbon and hydrogen as the main compositions. The carbon derived from RTB was mixed

Development Trends in EAF Steelmaking
JOM, 1986Since 1960, construction and technological improvements have enabled shorter tap-to-tap times in electric arc furnace operation. The conversion cost in arc furnace melting is primarily influenced by power consumption, electrodes and refractories. Increases in installed power capacity accelerate the melt down stage.
