Continuous casting using rollers having varying radii across their width

摘要

A method of casting molten metal into an extended solid comprises casting the metal between pairs of collaborating moulded rollers in which the moulding radii vary across the width of the roller. Sections of metal are produced by being continuously cast between this pair of rotating rollers. The shape of the section produced may be for example angular or ellipsoidal and may be produced as a shape of an intermediate stage to be finished by a stage of conventional rolling. The maximum and minimum radii of the casting rollers are arranged to be respectively equal so as to minimise the strain in the metal being cast. IMAGE
