发明名称 SCHRAEGWALZWERK ZUR HERSTELLUNG VON RUNDPROFILEN
摘要 The invention relates to a method of manufacturing solid metallic materials having a circular cross section by employing a rotary mill. A three or four roll cross-type rotary mill is employed, with cross and feed angle setting selected so as to meet specific conditions. The method permits efficient production of metallic materials without internal cracks or internal fracture initiated from porosity. In one version of the method the material being worked is rotated. In another version the material is not rotated and the roll housing is rotated around the former. Where the latter version is employed, it is possible to work the material as produced by a continuous casting machine and without cutting.
