  • Open hearth furnace Wikipedia

    The openhearth process is a batch process and a batch is called a "heat". The furnace is first inspected for possible damage. Once it is ready or repaired, it is charged with light scrap, such as sheet metal, shredded vehicles or waste metal. The furnace is heated using burning gas. Once the charge has melted, heavy scrap, such as building, construction or steel milling scrap is added, together with pig iron from blast furnaces. Once all the steel has melted, slagforming agents suBlast furnace Definition, Temperature, Diagrams, & Facts,1998720· Modern blast furnaces range in size from 20 to 110 metres (70 to 360 feet), have hearth diameters of 6 to 15 metres (20 to Features of FASTMET Process KOBELCO,steel mill waste or iron ore fines, into metallized iron in a rotary hearth furnace (RHF) using solid carbon sources, such as coal, as the reductant.
