Reusing the coproducts of the steel industry, Blupe Steel. The worldwide average recovery rate for slag varies from over 80% for steelmaking slag to nearly for ironmaking slag.
Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...

During the pyrometallurgical treatment of the nickelbearing laterite in the plant of LARCO, slag is produced after treatment in electricarc furnace (EAF) that contains to % Ni.
A method of operating a channel induction furnace so as to receive electric arc furnace (EAF) dust, basic oxygen furnace (BOF) sludge/dust and/or other iron and volatile metals containing materials as a feed stream on a batch, continuous or semicontinuous basis together with a ironcontaining material feed, and therefrom produce an ironcontaining hot metal or pig iron product while ...
meltin. The partition of phosphorus in the slag to phosphorus in the bath ranges from 5 to 15. Usually the phosphorus is reduced by 20 to 50 % in the EAF. Sulfur is removed mainly as a sulfide dissolved in the slag. The sulfur partition between the slag and metal is dependent on slag chemistry and is favored at low steel oxidation levels.

The slag from the upgrading step would be recycled back to the DCarc furnace at industrial scale, in order to recover the portion of valuable metals that have been reoxidized. It is possible to arrange conditions in the two process units such that an alloy containing only 30% iron is produced, even though a cobalt recovery of 80% is achieved.
Steel Steel Electricarc steelmaking: About onequarter of the world''s steel is produced by the electricarc method, which uses highcurrent electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. .

The recovery of alloying additives depends on the type of furnace and individual foundry practices. EAF operations had greater variations in final chemistry performance than induction furnace operations. Laboratory experiments showed that there is a potential for increased alloy recovery and control through argon stirring with a porous plug. Argon

Jan 01, 2003· Steel slag is produced from Basic Oxygen Furnace (BOF steel slag) and Electric Arc Furnace (EAF steel slag) in the steel making. They are about 10–15% by weight of the steel output (Proctor et al., 2000).Each year, a great amount of steel slag is produced in the different countries, as shown in Table 1.
Jul 23, 2020· The conditions that drive chemical reactions between slag and metal are impaired by insufficient intermixing of slag and metal during the process. That''s not all. There is an additional limitation. The design of an EAF is such that there is always a possibility of slag flowing out through the slagdoor early in the process.
