Biodiesel is one of the most environmentally friendly and renewable fuels, as it a non-polluting fuel made from living resources, such vegetable oils. The steel industry generates variety solid wastes, including electric arc furnace slag (EAFS). synthesis biodiesel waste sunflower cooking oil was examined in this study, utilizing EAFS catalyst, which mainly contains ferric ferrous oxides, calci...

Hydrogen-based direct reduction is a promising technology for CO2 lean steelmaking. The electric arc furnace the most relevant aggregate processing reduced iron (DRI). As DRI usually added into arc, behavior in this area of great interest. A laboratory-scale hydrogen plasma smelting (HPSR) reactor was used to analyze that under inert conditions. Four cases were compared: carbon-free and carbon-...

A dynamic, first-principles process model for a steelmaking electric arc furnace has been developed. The is an integrated part of application designed optimization during operation the furnace. Special care taken to ensure that non-linear robust and accurate enough real-time optimization. formulated in terms state variables ordinary differential equations adapted data using recursive parameter ...

The feasibility of using EAF slag aggregate, fly ash, and silica fume in pavement Electric Arc Furnace Slag Concrete (CEAFS) is the focus this research. aggregate volume stable suitable for use concrete, according to findings testing. was utilized replace natural coarse aggregates CEAFS mixes. created by blending 50% crushed stone with aggregates, ash (FA) (SF) partially replacing cement at con...
