The Thomas Steel Works in Liege-Ougree

 Thomas Steel mill Cockerill-Ougree
With the construction of three new steelworks at the end of the 1950s, the Thomas steel making process (Basic-Bessemer) experienced its technical peak and a final blossoming.
Between May 1958 and August 1959, HADIR in Differdange, Phoenix Rheinrohr in Duisburg and Cockerill-Ougree in Liege commissioned a total of 13 converters with tapping weights between 50 and 70 tons.
All of them had been planned and built by DEMAG in Duisburg.

The Thomas steel plant in Liege-Ougree, with its futuristic façade at that time,
will remain the last new construction of its kind in the western world.
Five 56 t Thomas converters and two 1500 t hot metal mixers were put into operation on 4 August 1959 and were supplemented by a 60 t LD-AC converter in 1962.
In December 1975 the Thomas steel works in Liege were shut down.
5 years later the use of the basic bessemer process in the western hemisphere was finally terminated.

  1. OBM Réhon – possibly the most short-lived steel plant ever built. Had the pagoda roof, too.

  2. Are you aware that much of the building and equipment from this Thomas Steel plant at Seraing/Ougree when it closed in 1975 was transferred to Providence, Usine de Réhon and used up until the closure of the Réhon works in 1987.

    “…Le locotracteur Cockerill No 2 dans le secteur démoulage des lingots. L’ensemble des voies étroites de l’aciérie était desservi par trois locotracteurs télécommandées, dont un en réserve pour les dépannages. L’aciérie OBM de Réhon a été construite en récupérant à Ougrée le charpente et les ponts roulants d’une aciérie Thomas arrêtée. Egalement récupérés les cars de coulée en lingotières et les locotracteurs. (Fusion 1982/1)…”
