The fields of appliation of grinding steel balls are in ore processing and the cement industry (material grinding in ball mills); large-size rolling bearings, etc. In mass machine production, for the manufacturing of axisymmetric forgings, cylindrical billets can be effectively replaced by balls. Balls are now produced by casting, die forging, and rolling. Cast grinding balls find a limited application. Hot-rolled balls are produced according to a power-consuming technology, as the ball-rolling mill employs pre-deformed (rolled) billets. The process of ball die-forging is inefficient, as it requires great power and material consumption, etc. In this paper a new technology for producing ball-shaped billets out of continuously cast ingots is presented.
