Steel in Translation Aims and scope

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.
