- 1954: Founding of Concast. Concast was founded in 1954 by Irving Rossi and Dr. Heinrich Tanner with the aim was to launch the new continuous casting technology on the European market. This earned Rossi his place in history: he was the first person to transfer the casting process from non-ferrous metals to steel. Plant operators were thus able to achieve considerably better productivity than before – a revolution in the steel industry in the middle of the 20th century.
