Power quality determines the fitness of electrical power to consumer devices. .Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnace operation. Utilities are concerned about these effects and try to take precautions to minimize them. Therefore an accurate model of an arc furnace is needed to test .In this paper a...

Introduction Fast, efficient batch melting using the modern induction furnace can improve operating flexibility and production yield, as well as reduce the cost of environmental protection. The compelling advantages of induction batch melting have encouraged foundries to change the way they handle their melting operations. Among the chief advantages is cost. The operational cost of a typical in...

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...

This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

Electric arc furnace slag (EAFS) and electric dust (EAFD) are the waste materials from steel production by EAF route which implies remelting of iron scrap in furnaces (EAF). In recent years, special attention is paid on valorisation EAFS EAFD since disposing both may cause negative impacts environment. this paper, methods that use to process have been reviewed, their advantages disadvantages al...

The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidate...

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-...
