Title: A review of the use of anthracite in electric arc furnace steelmaking

Abstract

The applications of anthracite in Electric Arc Furnace (EAF) steelmaking, include the adjustment of hot metal carbon content, the generation of foamy slags, and its use as a support fuel in the EAF to reduce power consumption per tonne of product. Incentives to use support fuel in EAF steelmaking include the reduction of electric power consumption without reducing plant output. As such, the concept can reduce steelmaking costs and can serve as a basis for maximizing an EAF operation`s demand side management program. The use of carbon and oxygen additions to the EAF can cause significant release of energy within the furnace. This energy can offset a portion of the electrical energy required by the system for production of steel. Reduced consumption of electricity per tonne of hot metal is the result Electrode consumption and tap to tap times can also be reduced. significant interest in the use of anthracite as EAF support fuel, as well as the other applications of anthracite in EAF steelmaking, have combined to establish the EAF steelmaking trade as a significant market sector for anthracite. This discussion is a review of key anthracite properties and production considerations, and their interplay with the requirements of themore » EAF process.« less
