melting and refining furnaces | daido steel
Ladle furnace (LF) The LF is the melting furnace developed by Daido Steel Co., Ltd. The LF equipment, which conducts reducing melting such as deoxidation, desulfuration, and removal of non-metallic enclosures, is indispensable to the steel making process of the arc furnace corresponding to the reduction of the scrap material quality and the needs for the product quality improvement.
ladle refining furnace - mechanical engineering concepts ...
Ladle Refining Furnaces are applied for de-sulphurising the molten metal and also for removing the impurities from molten metal. Ladle refining furnace holds the liquid metal for process of casting. Before Ladle Refining treatment there will be melting process which could be processed either in electric arc furnace or in the Induction Melting Furnaces.
refining (metallurgy) - wikipedia
The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually ...
Secondary Refining For purposes of this article, Secondary Refining or Secondary Metallurgy is defined as any post steelmaking process performed at a separate station prior to casting and hot metal desulfurizaion. It does not include normal alloying prac tice in the furnace or at the ladle during tapping.
ladle refining furnaces (lrf) | inductotherm corp.
Ladle refining of liquid metal is a proven technology to produce high quality steel. A Ladle Refining Furnace is used to raise the temperature and adjust the chemical composition of molten metal. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during refining with conventional ladles.
ladle refining [substech]
Ladle Furnace process is used for refining a wide variety of steels, in which degassing (hydrogen removal) is not required. to top. Ladle desulfurization by injection of active agents. Injection of desulfurizing agents (Ca, Mg, CaSi, CaC 2, CaF 2 +CaO) to a molten steel is the most effective method of sulfur removal.
