Rendering of a ladle furnace, a variation of the electric arc furnace used for keeping molten steel hot. For steelmaking, direct current (DC) arc furnaces are used, with a single electrode in the roof and the current return through a conductive bottom lining or conductive pins in the base. The advantage of DC is lower electrode consumption per ...
A submerge-arc furnace's shell or casing is fabricated from steel. The lower part is lined with hard blocks of strongly calcined carbon, and the upper part with firebrick. The floor and lower section of the furnace are water-cooled. Three electrodes are placed at the angles of an equilateral triangle with rounded corners.
With an investment of around Rs 185 crores, a 45 MW Sub-merged Arc Furnace with a production capacity of around 90,000 tonnes of High Carbon Ferro Manganese or 70,000 tonnes of Silico Manganese is under construction. It is expected to be completed by 2015. With an investment of 38 crores, a 4 MW (furnace gas based) Power Plant is also envisaged.
The indirect arc electric furnace of the Stassano type, in its final configuration, is made from a cast iron cylindrical structure lined internally with refractory bricks. The structure is divided in two separate sections: an upper section where the electrodes are placed, and a lower crucible where the burden is loaded and fused into steel.
To supply its mills, Nucor uses electric arc furnaces and continuous casting to melt scrap steel as opposed to blast furnaces to melt iron. In 2023, the company produced and sold approximately 18.5 million tons of steel and recycled 18.4 million tons of scrap. [1] None of Nucor's mills are unionized and the corporate culture is opposed to trade ...
The company said it had ceased operations of Blast Furnace 5 at the south Wales site as part of its restructuring programme. Steel giant Tata shuts down one of two blast furnaces at Port Talbot ...

A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy ; processing metals with heat is even its own engineering specialty known as pyrometallurgy .
