The volatilization of zinc in the electric arc furnace dust–CaCl2 and ZnFe2O4–ZnO–CaCl2–C reaction systems was investigated. Experiments were conducted under an N2 atmosphere infrared lamp heating furnace, activation energy rate determined by Ozawa method. system 123 ± 27 kJ/mol; when dust decarburized, reduced to 84 4 kJ/mol. Further, simultaneous carbothermic reduction carbon contained chlori...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

This paper illustrates how systems requirements (i.e., safety) are decomposed to define manufacturing process requirements and design. Steelmaking is an energy intensive process; utilizing vast amounts of electricity, oxygen, and natural gas to liquefy scrap steel. While the electric arc furnace process is used extensively around the world to melt steel, it is inefficient. Hot gases are lost to...

The in-plant recycling routes of several side streams produced in Electric Arc Furnace (EAF) steelmaking remain under-explored. In article 2100472, Abdelrahim and co-workers characterize eight use them to produce seven different briquettes. Briquettes are assessed for their suitability be used EAF through a series mechanical high-temperature tests, reflecting intended use.
