Pre-melt refined slag (calcium aluminate, desulfurizer) is a kind of compound deoxidization and desulfurization material, which is a must used in steel and steel refining process.The chemical composition of calcium aluminate is homogeneous, the melting point is low, the melting speed is fast, and the smelting time can be shortened.No fluorine, no erosion furnace lining and ladle;Dense ...
Primary steelmaking uses mostly new iron as the feedstock, usually from a blast furnace. Secondary steelmaking is performed in an electric arc furnace and uses scrap steel as the primary raw material. Refining consists of purifying an impure metal. Wrought iron and refined iron are products of pig-iron refining.
A process is disclosed for refining an iron product containing not more than about 10% by weight oxygen and not more than about 10% by weight sulfur, comprising providing an electrolyte of a slag containing one or more of calcium oxide, magnesium oxide, silica or alumina, providing a cathode of the iron product in contact with the electrolyte ...

The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal known as finers metal or refined iron.

carbon injection, slag basicity and MgO content. Ladle refining is probably the most important part of steelmaking since it is here where the hot iron units from the furnace are changed into a salable high quality steel product. Ladle refining implies the following: • .
The first stage of the scrap-based steel industry production generates EAF slag (EAFS) and a second stage is performed to refine the molten steel. The slag produced in the LF (LFS) is the result from steel refining and, therefore, it is generally a heavy metal carrier such as chrome, lead or zinc (CEDEX – Ministerio de Fomento, 2018).

Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 (fluxing oxides). As oxygen is blown into the furnace, the principal flux (FeO) is generated. The "slag balance" now starts to shift and the slag becomes more liquid.
