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. Open-Hearth Furnace an open-flame regenerative furnace for making steel of a given chemical composition and. 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 in , while 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 .
