   procédé à sole ouverte (ou procédé Martin-Siemens)

   • The open-hearth process was widely used in the 20th century for steel production.
   • Modern steel plants have largely replaced the open-hearth process with basic oxygen furnaces.
   • The open-hearth process allows for better control of the steel's chemical composition.
