Abstract
The post-war restoration of the mining and metallurgical complex of Ukraine is one of the most urgent tasks of developing Ukraine's industrial potential and strengthening its economic independence. Solving this task lies in the development of competitive products, which would be such both in terms of quality and in terms of the consumption of materials, resources and energy for their production. In the production of railway rails, an optimal technological scheme of high-quality steel smelting is established, which is based on the functional chain "installation for out-of-furnace processing of cast iron - melting unit - complex installation of out-of-furnace steel proofing or "bucket-furnace" installation, as well as a vacuum cleaner - machine for continuous pouring of steel". On the basis of world experience, the technological features of production and continuous pouring of railway steel are considered and analyzed. Recommendations are presented regarding technological measures that must be implemented at "KAMET-STEEL" PJSC for the effective production of railway rails in the post-war period, taking into account world experience. It is recommended to implement in steelmaking production of multi-level oxygen lances, which will allow to increase the share of scrap metal in the charge by 10-15%, and when using a gas powder lance, it is possible to achieve almost 100% of the share of scrap metal in the charge. At the stage of continuous casting, it is recommended to observe rational temperature and speed regimes of casting in accordance with world experience.
