Abstract The primary process in an electrical arc furnace (EAF) during industrial steelmaking results tons of black slags which cause pollution to the environment. In this work, iron oxides generated EAF from SIDERPERU plant, Peru was reduced via carbothermal reaction. reduction slag α-Fe is demonstrated by X-ray diffraction, Mӧssbauer spectroscopy and magnetometry. However, phases with calcium...

In the present study, viscosity of CaO–SiO2–FeO–Al2O3–MgO slag system was measured for recovery FeO in electric arc furnace (EAF) process using Al dross. Considering MgO-saturated operational condition EAF, composition at 1823 K with varying and Al2O3 concentrations. An increase decreasing temperature observed. The activation energy evaluated, change thermodynamically equilibrated phase conside...

The European steel industry produces about 70 million tons/year of by the electric arc furnace (EAF). slag consists 15% weight produced steel, thus from perspective circular economy, it has a high potential as co-product. This research aims to assess an innovative reuse EAF filler in different polymer matrixes: thermoplastic (polypropylene), thermosetting (epoxy resin), elastomeric (nitrile but...

Steelmaking in the electric arc furnace (EAF), either scrap-based or based on hydrogen direct reduced iron, will future contribute substantially to reduction of CO2 emissions iron and steel industry. However, there still be need introduce carbon into EAF process carburize create foaming slag improve energy efficiency melting process. So, reach emission goals set around world, it necessary subst...

The effect of the curing in a carbonated ambient of the solids obtained after the stabilization/solidification (S/S) of metallurgical waste using geopolymerization technology is described in this paper. The electric arc furnace (EAF) dust used to stabilize contains hazardous metals such as Pb, Cd, Cr or Zn. Different geopolymeric agents as potassium hydroxide, potassium silicate, metakaolin and...
