  • Description
  • The open-hearth process of steel making was first developed in Europe by Siemens in England and Martin Brothers in France. The process was introduced to the United States in 1868. Jones & Laughlin Steel Corporation first went into open-hearth production in 1895 when it constructed two 40-ton basic furnaces. Once the steel inside the furnace was ready, it was tapped from the side opposite to the charging side by knocking a tap hole in the side. The steel was poured out into a ladle and a crane, which filled the molds as in the Bessemer process, manipulated the ladle. This type of furnace could be built more cheaply and run more efficiently than Bessemer converters since it could use the scrap steel that resulted from the Bessemer process. The open-hearths shown in the photograph were at Jones & Laughlin Steel Corporation's Pittsburgh Works.
