Abstract
The creation of metallurgical microworks intended for processing metal scrap to specialized bar iron at an annual output of 50 000 to 100 000 tons is a topical matter. In terms of loading the rolling mill with special kinds of rolled metal used at the regional level, the organization of making grinding balls (bodies) at a microworks fits within its process system almost ideally. This study provides the results of industrial tests aimed at making the end-to-end quality assessment of concast billets, derived rolled stock, and grinding balls at an integrated specialized metallurgical microworks. It is shown that the comprehensive solution of technology-related matters allows making high-quality finished rolled stock. In particular, the optimization of process parameters for making grinding balls of 60 mm in diameter allows reliably attaining hardness group V when using grade 75 steel teemed in jets protected against secondary oxidation.
