What is the electrical aspect of a furnace?

The electrical aspect deals with the furnace power requirement to make it functional. A blast furnace performs basic melting (of iron ore) operation to get pig iron, cupola furnace is used for getting cast iron and an electric arc furnace is used for re-melting steel.

What is electric smelting furnace (ESF)?

.Electric Smelting FurnacesESF technology is a well-known and long-established electric melting technology in the nonferrous metals industry. These m lting units can be engineered using two different fundamental designs: The so-called six-in-line EAF, with its rectangular shell design, and the round ESF. Both are widel

What is a furnace used for?

Index Terms— electric heating, mechanical electrical components, melting, heat distribution. furnace is an equipment used to melt metals for casting or to heat materials to change their shape during the processing of the product (e.g. rolling, forging) or to enhance properties of the processed components (heat treatment).

What is an electric furnace?

This furnace can be described as a furnace heating charged materials by the way of an electric arc. The first electric furnaces came into being in 1907, at the hands of Paul Heroult of French origin. The commercial part of these furnaces was established in the USA.

Why do people use electric furnaces?

Electric furnaces are used where more accurate temperature control is required. Melting of metals, glass, and other materials has been a vital manufacturing process for several thousand years, producing molten liquids that can be poured and solidified into useful shapes.

How does an electric furnace work?

An electric furnace in which the heat is developed by the passage of current through a suitable internal resistance that may be the charge itself, a resistor embedded in the charge, or a resistor surrounding the charge.
