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.

综合专业冶金微厂产品质量的端到端评估

摘要

创建用于将金属废料加工成年产量为 50 000 至 100 000 吨的专用棒铁的冶金微厂是一个热门话题。在向轧机装载区域级使用的特殊类型的轧制金属方面，在微工厂制造磨球（体）的组织几乎完美地适合其工艺系统。本研究提供了工业测试的结果，旨在对集成的专业冶金微厂中的连铸坯、衍生轧件和磨球进行端到端的质量评估。结果表明，技术相关问题的综合解决方案可以制造出高质量的成品轧件。特别是，
