Introduction Open hearth furnace is the oldest method of melting pig iron to produce steel.Steel,which has a high melting point,cannot be melt using the commonly used fu rnace.Using the regenerative firing method,upto 1600°C of heat can be produced that is required melting pig Iron for steel.Open Hearth Process - Steel MuseumAn open hearth furnace has a lining of refractory and a low,arched roof that covers the hearth,which is open directly to flames that melt the charge.This process uses about equal amounts of iron and scrap.Steel is produced in an open hearth furnace by the following steps:.1.A machine dumps limestone and scrap steel (the charge) into the furnace.Open Hearth Process - an overview ScienceDirect TopicsDifferent from converters,open hearths and electric furnaces suited well for further refining of the crude steel.The charge could be heated for a longer period to make deoxidation,desulfurization,and alloying in the furnace.Initial oxidizing slag was raked off and a new strongly basic slag was formed.
Open-hearth furnaces are one of several kinds of furnace in which excess carbon and other impurities are burnt out of pig iron to produce steel.Since steel is difficult to manufacture owing to its high melting point,normal fuels and furnaces were insufficient and the open-hearth furnace was developed to overcome this difficulty.Compared to Bessemer steel,which it displaced,its main Open hearth furnace Article about Open hearth furnace by Open-hearth furnaces are called acid or basic,depending on the nature of the refractory materials lining the melting chamber.Magnesite,magnesite-chromite,and chrome-magnesite bricks are used to line basic open-hearth furnaces,and magnesite powder is used to fettle the hearth.Open hearth furnace synonyms,Open hearth furnaceSynonyms for Open hearth furnace in Free Thesaurus.Antonyms for Open hearth furnace.1 word related to open-hearth furnace furnace.What are synonyms for Open hearth furnace?
