“Hot metal is supplied to Chertal from the six blast
furnaces of the Esperance-Longdoz plant at Seraing,
some 14 miles distant on the other side of Liege. In
order to provide transport on the lines of the Belgian
National Railway, it was necessary to design special
torpedo-type ladle cars. These cars can carry 165
tons of hot metal, but because of the heavy weight
of the refractories, the total car weight is about 330
tons. In order not to exceed the maximum permitted
railway load limit, it was necessary that the length
of the ladle cars be 31 meters. However, the mass of
hot metal is concentrated in the central part of the
torpedo ladle with the largest cross-section so as to
minimize the heat loss.” (1/1964, JOURNAL OF METALS)
The cars where manufactured by German DEMAG company.

The Rothe Erde GmbH was founded in 1855 in Dortmund under the name Paulinenhütte. Main product was railroad equipment.In 1861 the Rothe Erde steel company from Aachen purchased the mill an gave it it’s final name. From 1926 on Rothe Erde was part of the Vereinigte Stahlwerke, the second largest steel producer worldwide. After rebuilding the destroyed works in the 1950ies Rothe Erde became part of the Hoesch steel group in 1966 and started to built up a modern ring rolling mill at their Dortmund works.
After the takeover of Hoesch by the Fried.Krupp steel company in 1993 Rothe Erde finally became part of the ThyssenKrupp group in 1999.Nowadays the Dortmund works are one of the largest ring rolling mills in Europe producing rings up to 8 meters.Further processing of rings to bearings or turntables is done in Dortmund and Lippstadt.
