Innovation in the processing of tonnage materials: examples from the steel and aluminium industries

摘要

Two developments in the processing of the tonnage metals steel and aluminium are described. In one case, the introduction of a new steel grade enabling elimination of some of the expensive manufacturing steps currently employed is makingsignificant savings in the production of forged automotive components. In the other case, the twin roll casting process for the production of aluminium sheet has been extended to higher speeds and thinner gauges, resulting in higher productivities. Someof the reasons permitting these developments are introduced and discussed.
