The general plan of the metallurgical enterprise based on the technology of liquid phase reduction of iron

The paper presents the results of the development of technical solutions for the technology of liquid-phase reduction of iron and continuous steel production aimed at creating energy-efficient metallurgical production.

The main purpose of this work is to develop a comprehensive technology for the continuous production of hot-rolled sheet based on an innovative continuous-acting steelmaking unit (hereinafter SAND), which is based on the principle of liquid-phase reduction of iron. The main task is to create a technology for off-domain continuous reduction of iron with a carbon-hydrogen mixture by purging with natural gas, which makes it possible to maximize the use of fuel energy.

Based on the installation being developed, a master plan with the location of the main equipment is proposed. It takes into account the logistics of material flows when creating a new metallurgical enterprise. Special attention is paid to the development of recycling systems for secondary energy resources and the analysis of environmental performance indicators of the process.

The scientific and practical significance of the study is confirmed by the technical feasibility of introducing alternative steel production technologies, demonstrating a significant reduction in greenhouse gas emissions compared with aglocoxodomain technology, as well as the prospects for increasing the competitiveness of metallurgical production. The results obtained can serve as a basis for the development of a feasibility study for the design of an industrial installation.
