What is an Open Hearth Furnace? - wiseGEEK

Open hearth furnaces are furnaces that are often used in the production of steel.Designed with a somewhat shallow hearth and roof that is lower than other furnace designs,the open hearth furnace creates an environment that aids in the removal of impurities from the pig iron that is used in the steelmaking process.US1736023A - Open-hearth-furnace construction - GoogleUS1736023A US30589628A US1736023A US 1736023 A US1736023 A US 1736023A US 30589628 A US30589628 A US 30589628A US 1736023 A US1736023 A US 1736023A Authority US United States Prior art keywords furnace air pressure hearth fuel Prior art date 1927-05-16 Legal status (The legal status is an assumption and is not a legal conclusion.US1736023A - Open-hearth-furnace construction - GoogleUS1736023A US30589628A US1736023A US 1736023 A US1736023 A US 1736023A US 30589628 A US30589628 A US 30589628A US 1736023 A US1736023 A US 1736023A Authority US United States Prior art keywords furnace air pressure hearth fuel Prior art date 1927-05-16 Legal status (The legal status is an assumption and is not a legal conclusion.
