SECONDARY METALLURGY

LF The Ladle Furnace (LF) is the fundamental secondary metallurgy solution for improved productivity, ˜exibility and uality. Tenova Ladle Furnaces are usually designed to increase the melt temperature up to 5 C/min. They are euipped with either a direct-or an.

Effect of Slag Chemistry on the Desulfurization Kinetics …

During the secondary refining process, slag chemistry is very important since sulfur is removed via slag-metal reactions. Typically, the CaO-SiO 2-Al 2 O 3 -based slags are used and MgO is added to prevent excessive corrosion of the MgO-C-type ladle lining.

Properties and Uses of Steelmaking Slag

 · Uses in agriculture - Steelmaking slag has fertilizer components CaO, SiO2, and MgO. In addition to these three components, it also contains components such as FeO, MnO, and P2O5, so it has been used for a broad range of agricultural purposes. Its alkaline property neutralizes soil acidity.

Secondary aluminum (REKAL)

K+S recycles salt slag from the secondary aluminum industry completely residue-free. By this we mean: completely, one hundred percent. Our specially developed REKAL® plant extracts the reusable aluminum from the slag. The process is rounded off by the separated substances potassium chloride, aluminum oxide and ammonium sulfate.

Steel

 · An open-topped cylindrical container made of heavy steel plates and lined with refractory, the ladle is used for holding and transporting liquid steel. Here all secondary metallurgical work takes place, including deslagging and reslagging, electrical heating, chemical heating or cooling with scrap, powder injection or wire feeding, and stirring.

Precious metal recoveries in secondary copper smelting …

 · The residual aluminum in secondary copper feed entering the furnace will have an influence on the slag properties and, therefore, on the success of the entire copper smelting process. The black copper smelting process includes reduction and oxidization smelting stages carried out in either order at the same furnace or consecutive furnaces, such as Ausmelt TSL (top submerged lance) [ 8, 9 ].
