This document is written to give expansive and critical idea about Iron Foundry. It also gives concepts about different sorts of furnace used as per duty.

Before understanding what Iron Foundry is, let's understand what is mean by Foundry. A foundry is nothing but a factory that generates metal casting. Metals are modified into liquid and poured in a mold. Once metal is solidified and cooled, mould is removed.

Iron foundry is commonest foundry known beside Aluminium foundry. But Steel, Zinc, Tin and Magnesium foundries are also found. There are different kinds of furnace, use of which relies upon your need and project.

Cupola Furnace

For some considerable time, cupola was the only prime technique of melting practiced in iron foundry. Reason for its wide-reaching goes to its individuality. Following are the features of cupola furnace that contributed to its wide success.

1 ) It's only "unbroken Operation" method

two ) Liquefying Rates are far above the ground

3 ) Trouble-free procedure

4 ) Rather low working cost

The cupola can be made of roughly any reasonable size. The size of a cupola is told in diameters. Generally it goes from 18 inches to 13 feet. On the whole, shape is cylindrical and the apparatus is set upright.

Cupola furnace easily catch high temperature, hence sometimes Iron and Bronze are liquified through it. However , occasionally it is used for melting of aluminium maintaining low temperature with a great care.

Reverberatory

Reverberatory is a well recognized name in the world of metallurgical. The chief duty of reverberatory furnace is to detach the processed material from approaching in communication with blaze or the fuel.

Due to its operations, functions and objectives reverberatory furnace is classified into two categories.

1 ) Liquefying or Fusion Furnace

2 ) Calcining or Wasting Furnace

Why to use reverberatory furnace?

1 ) It is very fertile

two ) Simple to utilise

three ) Hassle-free installation

four ) Total access to furnace chamber for clean-up and charging

5 ) The likelihood of rust and melt loss is least

Reverberatory furnace has following Use :

1 ) Removing

two ) Refinement

3 ) Tin, Copper and Nickel making

4 ) Melting

five ) Aluminium recycling

Electric Arc Furnace

Frequently used in commercial foundry, electrical arc furnace isn't famous and seldom employed by casters due to its heavy expenditure, breathing space issue, and wide-ranging nuisance. There are two sorts of electrical arc furnace, 1 ) Direct Electric Arc Furnace and 2 ) Indirect Electric Arc Furnace. The one difference between two is Direct Electric Arc uses three electrodes, while Indirect Electric Arc uses one electrode.

While the new electric arc furnace is a particularly proficient recycler of steel crumb, process of an arc furnace shop can have adverse ecological effects.

Electrical Induction
The electrical induction furnace is a kind of liquefying furnace that utilises electrical currents to melt metal by passing currents thru gigantic coils encircled on the crucible. The chief advantage of using this method is controlled and clean softening procedure along with the advantage of energy conservation.

So , these were the few types and techniques of furnace employed in Iron foundry for melting and casting Iron according to need and project.
