In open hearth furnace, pig iron, steel scrap etc. are melted to obtain steel. This furnace is widely used in American foundries for steel production. The hearth is surrounded by roof and walls of refractory bricks as shown in image below.

Open hearth furnaces are one of a number of kinds of furnace where excess carbon and other impurities are burnt out of pig iron to produce steel is difficult to manufacture due to its high melting point, normal fuels and furnaces were insufficient and the open hearth furnace was developed to overcome this ed to Bessemer steel, which it displaced, its main.

open-hearth furnace[′ōpən ¦härth ′fərnəs] (metallurgy) A reverberatory smelting furnace with a shallow hearth and a low roof, in which the charge is heated both by direct flame and by radiation from the roof and walls of the furnace.

The total oxygen levels in ball-bearing steels produced at Ovako Steel Hofors (former SKF steel) via the acid open hearth process () and later via an electric arc furnace and an ASEA-SKF ladle furnace followed by ingot casting are given in Figure The oxygen content in the open hearth process was on average 35 ppm inwhile when.

Open-hearth process, also called Siemens-martin Process, steelmaking technique that for most of the 20th century accounted for the major part of all steel made in the world.

William Siemens, a German living in England in the s, seeking a means of increasing the temperature in a metallurgical furnace, resurrected an old proposal for using the waste heat given off by the furnace; directing.

The charge is collected directly from an open hearth furnace, the intense arc heat keeps the charge in its molten state, and the impurities are removed in the form of slag. The high frequency furnace is based on the principle that when high frequency alternating current is applied to.

To begin the process, the basic open-hearth furnace is charged with scrap, limestone, and iron ore. This initial charge lies on an "open" hearth, where it is melted. The Siemens-Martin oven in open hearth steelmaking is also a reverberatory furnace. Reverberatory furnaces (in this context, usually called air furnaces) were formerly also used for melting brass, bronze, and pig iron for foundry work.
