发明名称 PROCEDE ET APPAREIL DE FABRICATION DE PIECES A USINER METALLIQUES,ANNULAIRES OU TUBULAIRES
摘要 Metal annuli formed of chill cast metal for subsequent conversion into finished products are produced between at least one pair of inner and outer rollers forming between them a roll-pass, the outer one of which is driven and the inner one, of less diameter than the open central area of the annulus being formed and eccentrically positioned in said open central area, is free turning. Provision is made for moving the axis of rotation of the annulus being formd as the overall diameter increases in such manner that the relation between place of delivery of the hot strip with respect to the winding apparatus remains constant. Preferably the annulus forming apparatus is combined with a continuous casting apparatus whereby the formation of the strip and the forming of the annulus take place at the same speed.
