synopsis-in this research, possible usage of eaf dust on cement is investigated. therefore, effects of addition of different percentages of eaf dust on the most important properties of cement such as hydration heat, water coefficient, viscosity, initial and final setting times, strength development and leachability of heavy metals were studied. results showed that eaf dust alters the characteri...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

The selective removal of lead and chlorine with minimizing zinc loss from electric arc furnace (EAF) dust is very important in the process for recovering high purity zinc from the EAF dust by high temperature metal recovery (HTMR) processes. In this study, the volatilization reaction of lead contained in the EAF dust was investigated at reaction temperatures between 973 and 1223K in air. The ma...

Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required ...

This study investigated electric arc furnace dust (EAFD) reuse as a raw material in concrete mixes. A comprehensive experimental program consisting of two phases of testing was carried out. The first phase included the replacement of ordinary Portland (Type I) cement by unsieved dust with the percentages of 0, 2.5, 5, 7.5 and 10%. The second phase included the replacement of quartz (filler) by ...

A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...
