In between 1954 and 1962 the Hoesch company in Dortmund, Germany built it’s third open hearth melt shop (SM-Stahlwerk III).
Two 180 ton furnaces were installed by 1956, two DEMAG 210 ton furnaces were added in 1961 and 1962. These might have been the last to be commissioned in West Germany.
Monthly output was less than 100000 tons, not enough to compete with the new BOF shop in Dortmund Hörde built in 1963  producing more than 300000 t/m.
The open hearth shop 3 was closed in 1982.
Some images of it’s remains: Stahlseite.
