Iron Steel - US EPA

“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 of other iron-bearing materials to produce new steel. The scrap metal used ...

Flux metallurgy Britannica

Flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.

Lime in the Steel Industry Graymont

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.

Converter Steel Production

The main charge materials – liquid hot metal and solid steel scrap – are put into the converter together with fluxing agents. Then oxygen is blown in through the upper hole, via a water-cooled injection lance, which leads to oxidizing melting at a high temperature, the final product of which is crude steel. During blowing, the majority of the charge carbon content burns out, and silicon ...

Flux Basics What is Flux

A good wetting agent leads to the flux being more efficient. You end up using less flux to solder an area than if there was no wetting agent. Less flux means that cost goes down and that should make everyone happier. Alternatively, excessive application of flux can result in poor control of soldering conditions because the volume of flux will vary from part to part. Heavy applications are ...

Lime, an essential component in the steel industry

Secondary Steel making can be divided into 3 main phases: Fusion. This is normally carried out in electric arc furnace (HAE or EAF). At this stage lime is once again added as fluxing agent to help, on the one hand, with the formation of slag (precipitating silicates) and on the other, to remove phophorus from the steel. In the end the ...
