What you need to know about furnace installation begins with understanding the type of furnace that best suits your needs. Goodman company offers a large selection of furnaces designed to make the selection process simple.
Both blast and electric arc furnaces are used in industrial settings to heat and mold metal. A blast furnace is used to make steel from liquid iron, while an electric arc furnace is used to make steel from scrap material.
The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace.
The furnace uses a huge, pear-shaped steel barrel line with refractory material. An overhead crane pours a ladle of molten iron (about 200 tons) from the blast furnace into the mouth of the basic oxygen furnace. The oxygen lance (pipe) is lowered to approximately 6 feet above the surface of the metal.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being forced or supplied above atmospheric pressure.
Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals. Rapid combustion is maintained by the current of air under pressure.
