steelmaking slag of mobarakeh steel company (msc) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. on the other hand, eaf slag in this company is almost free of zinc because of using more than 90 percent dri in the charge. therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. in...

This study investigates the potential to recover iron and chromium from a chromium-bearing carbon steel Electric Arc Furnace (EAF) slag. slag contains indeed about 30 wt.% Fe 2.5 Cr. However, minerals are intergrown at small scale (<100 µm) mostly contained in spinel phases which makes separation challenging. Several methods including Mössbauer spectroscopy, X-ray Diffraction, Scanning Elect...

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 purpose of this research was to study the feasibility incorporating steel slags into coarse bituminous mixtures. objective twofold: reduce dependence on natural aggregates, and provide a use for industrial by-products. studied come from manufacture carbon in electric furnaces are divided two types: Electric Arc Furnace (EAF) slag Ladle (LF) slag. mixture designed is concrete (AC22G), base c...

The gradual increase in industrial wastes allowed the utilization of these different areas. Steel slag, one wastes, is formed during reduction molten crude iron to steel basic oxygen furnaces (BOF) or scrap electric arc (EAF) and induction (IF). Removal, storage, disposal slag an important environmental economic problem. offers opportunities be used as alternative material various areas contrib...

This study aims to optimize the composition (body formulation) and firing temperature of sustainable ceramic clay-based ceramics incorporated with electric arc furnace (EAF) steel slag waste using general full factorial design (GFFD). The optimization is necessary minimize drawbacks high iron oxide’s fluxing agent (originated from furnace, EAF waste), which led severe surface defects closed por...

The foaming process is an important part of the electric arc furnace (EAF) steelmaking process. It can promote thermal efficiency and reduce refractory consumption. FeO a key material used during Unlike with other components in forming slag, amount be controlled by oxygen or carbon injection. Therefore, adjusting content most economical mode adopted for EAFs In this study, influence on physical...
