Abstract. In this paper, experience of mastering grinding balls from billet obtained in conditions of a shaped-casting shop, instead of a continuously cast billet, is presented in order to reduce costs and time for development of new steel grades. The experiment was carried out on alloyed steel grade Sh-11, with the production of ingot with cross section of 300´380 mm - identical to continuously cast billet, and then rolling it into a round billet and balls with a diameter of 120 mm. Further experiments in development of new steel grades under conditions of shaped-casting shop are expedient when improving methods and modes of casting billets, and bringing them closer in parameters terms to continuous casting machine.
