30 ton electric slag remelting furnace
A 30 ton electric slag remelting furnace is a versatile and multi-faceted piece of equipment used in the iron and steel manufacturing industry. The furnace is designed to melt slag, a by-product from the production of iron and steel, to form a more homogenous product. The furnace works by melting the slag at extremely high temperatures in an oxygen free environment. The resulting molten slag can then be poured into molds to form usable materials like cast iron or pipes.
The electric slag remelting furnace is composed of several main parts. The main vessel contains the combustion chamber which is lined with bricks. Temperature and pressure readings are monitored through thermocouples and pressure gauges. Slag and fuel are fed into the chamber, and the chamber is heated with burning electric arcs. These arcs heat a furnace roof to around without evaporating the slag or melting the bricks. A second vessel, called a refractory crucible, is placed at the base of the chamber to protect the material from heat and oxidation. The molten slag is drained into molds where it solidifies.
Compared to traditional methods of remelting slag like open hearth furnaces or induction furnaces, the electric slag remelting furnace offers several advantages. The process is far more efficient, melting approximately three times the amount of slag compared to the other methods in the same amount of time. The process is also far cleaner, with nearly no smoke or particulate matter being released. In addition, the electric arcs create a much more uniform temperature inside the furnace, yielding a better quality product. The entire process is also more cost effective as the electricity used to power the arcs is much cheaper than fuel used in conventional furnaces.
The electric slag remelting furnace has become an essential piece of equipment for all types of iron and steel production, from small scale operations to large enterprises. With a wide range of sizes and capabilities, the electric slag remelting furnace is an invaluable tool for providing the highest quality products at the most cost-effective price.
