Abstract

Relevance. Today, despite the slowdown in the consumption growth per year, the ideas of a metallurgical mini-plant continue their development.Objective. The research is aimed at developing the concept of the metallurgical mini-plant using secondary steel as a raw material. Methods Applied. The paper presents an overview of the state of mini-plants in the Russian Federation and in the world, as well as the classification of these factories. The research provides for development of the idea for the mini-plant. In the course of the research, it was decided to choose used rails as raw materials, and the products would include reinforcing steel and/or grinding balls. The manufacturing process under consideration included the following operations: heating rails for rerolling, rerolling rails into a billet and rolling billets into finished products. Several heating types were analyzed, and the most favorable one was selected subject to the criteria. A process flow chart was developed for such heating type, indicating its special features. Rerolling was considered with a process of rail separation into 2 or 3 parts. There was a schedule of the rolling mill section, its composition and technical characteristics. Result. The data were used to design a preliminary equipment layout at the industrial site for the specified mini-plant. Practical Relevance. The resulting production line is highly environmentally friendly, because electric current from hydroelectric power stations is used as a main source of energy, and the technology of secondary scrap remelting is not used. The developed technology has a favorable prospect of implementation in the current economic conditions, especially for areas with many railroad tracks.
