Abstract

Un lingote se provee en una línea de paso entre un empujador y un tapón, y el lingote se avanza y se atrapa entre una pluralidad de rodillos inclinados. Por lo menos cuando el lingote atrapado entra en contacto con el tapón y cuando La perforación y el laminado alcanzan un estado estable, la velocidad de avance del lingote no es menor a la velocidad de avance del lingote cuando se realizan La perforación y el laminado sin empujar el lingote hacia delante por el empujador en el estado estable. A través de este método de fabricación, pueden restringirse los defectos de la superficie interior en el extremo de la punta de la coraza hueca.
