Nov 12, 2013· Induction furnaces are an advanced version of the Electric furnaces. These furnaces have the ability to melt large amount metals without any trouble. This furnace save melting time compare to a traditional furnace. They also have the ability to build up heat, allowing the furnace to reach higher heat levels. This makes it perfect for […]
The proposed project is a Greenfield Steel Mill consisting of Primary Sponge Iron Plant, and Secondary Plant to produce Ingots/Rolled Products. The proposed project will consist of Rotary Kilns to process Iron-ore to produce Sponge Iron. The Sponge Iron, and M.S. Scrap will be melted in Electric Induction Furnace.
Furnace Fume Extraction Systems Induction & arc furnaces are offered to control their resulting pollution control by exctraction thro' swilling/ water cooled hoods or third hole. The extracted hot fumes & gases (often flame laden) are taken away to TECHFLOW air pollution treatment & control systems.
The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. Sponge iron manufacture is highly sensitive to raw material characteristics.

Efforts have also been made to calculated expected yield in melting furnace.
Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Alloy Recovery and Control in Steel Melting 4.1 - 3 Proceedings of 58th SFSA T&O Conf. Convective heat transfer, which is a function of bath stirring and superheat, governs shell melting. Several physical and chemical properties of alloy additions affect how the element is incorporated into the steel melt.
recovery. Certain metals such as copper and iron, as well as their oxides, will couple in an HF furnace thereby maintaining sufficient temperature to permit complete oxidation of the carbon and sulfur present in a sample. Accelerators Several metals have been used as accelerators over the years, however only a few have been adopted for routine use.
