Modern metallurgical industry consists of many of supporting and main plants, which require constant material investments.
The issue of saving material resources, raw materials, etc., as well as reducing the expenditure coefficient of the metal, optimization and flexibility of production, is an important part for metallurgical companies in the conditions of economic instability in the industrial sector.
Introduction Issues related to saving material resources, raw materials, etc., as well as reducing the expenditure coefficient of metal, optimization and flexibility of production, are important components for large metallurgical companies.
