In 1973, after good results with the conversion of the old Thomas (basic Bessemer) plant at Monceau, Forges de Thy-Marcinelle et Monceau ordered a new OBM-steel making shop (Oxygen-Bodenblasen-Maxhütte) from a consortium  VÖEST-Alpine–GHH-Sterkrade.The 17500 m² melt shop went into production in April,1976 and included a 2000 t hot metal mixer and three 150 t OBM-converters with 18 tuyeries each.

It was closed down in 2008 and will soon be gone.
