Steel mill slag produced from electric furnaces or open hearths typically contains one-third to one-half non-hydrated lime (primarily CaO with some MgO). The lime is added as a fluxing agent during steel production. Lime can absorb water through hydration for many years after the slag has been created.

A fluxing process for removing inorganic deposits from equipment used to produce base metals from ores by inclusion of alkali metal silicates, preferably as liquids or hydrates, as at least 10% of the fluxing agent, thereby improving effectiveness of the fluxing process.
In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals …

The cooling and fluxing agent consists of iron scale 70-90 wt%, steel smelting mud 5-25 wt% and sodium silicate as adhesive 1-5 wt%. It is produced by mixing the material in certain proportion, crushing into grinding machine to 32 mesh below fineness and pressing into pellet product. Compared with available technology, the cooling the fluxing ...
Mill scales generated in the hot rolling step of steel produced by electric arc furnace, EAF, together with reducing agent and fluxing material were used as raw materials. Sieve analysis, chemical composition, and XRD examination of mill scale were carried out.

"Integrated" steel mills use a blast furnace to produce iron from iron ore, coke, and fluxing agents. A basic oxygen furnace (BOF) is then used to convert the molten iron, along with up to 30% steel scrap, into refined steel. "Minimills" use an electric arc furnace (EAF) to melt steel scrap and limited amounts
located at or near steel mills to take advantage of the availability of a variety of iron-bearing raw materials, coke fines, and slag. Recently, some major iron producers have incorporated flux into pellets, and the fluxed pellets are transported to iron producing centers. ...
The production of steel in an EAF is a batch process. Stages include charging, melting, refining, slagging, and tapping. During the charging stage, scrap metal is introduced into the EAF. The charge can also include carbon and lime, a fluxing agent. Direct reduced iron (DRI) or other
"Integrated" steel mills use a blast furnace to produce iron from iron ore, coke, and fluxing agents. A basic oxygen furnace (BOF) is then used to convert the molten iron, along with up to 30% steel scrap, into refined steel.
Fluxes are used in blast furnaces, basic oxygen furnaces (BOP), electric-arc furnace (EAF) and other types of steel mills. The type of furnace and amount used depends on the quality of steel being made. For example, more limestone is needed to make high-quality stainless steel than ordinary hot-rolled steel.
Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces. Lime removes impurities (silica, phosphorus, sulfur) from the steel being manufactured. The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel.
Steel Manufacturing The largest utilization of lime products across the globe is for the production of Steel . Our lime removes impurities, acts as a fluxing agent, all while improving the overall quality of the steel.
The selective laser melting (SLM) is a method characterized by the application of metallic powder materials free of binders and fluxing agents, and the heating to melting temperature by a laser beam in such a way that the layer of metallic powder is fully molten throughout.
Fluxing. The acid-cleaned steel object is submerged in a flux solution comprising zinc ammonium chloride and is typically run at 50-70 °C. After acid cleaning, the flux solution eliminates any oxide layer that accumulates on the steel surface, preventing further oxidation before galvanizing and activating the surface. Without fluxing, the steel would be protected by an oxide layer which ...
