“…To study the effect of the amount of ligature on the impact strength and the contamination index for non-metallic inclusions of steel grade 12HGFL, laboratory research was conducted using the AEM. The results of the experiments are shown in Figure 1 [17,18]. As seen from Figure 1, the impact strength's dependence on the shield's flow rate in the entire temperature range (from plus 20 to minus 80 ° C) has an extreme character.…”

“…By cleaning steel from harmful impurities, REM improves its casting properties, fluidity, feeding conditions, and crack resistance of castings, as well as reduces the anisotropy of the mechanical characteristics of steel. The high efficiency of the effect of REM on the properties of steel is due to their favorable effect on the composition, type, shape, quantity, and uniformity of the distribution of the formed HB, a significant improvement in the macro-and microstructure of the workpiece, reducing its physical and chemical heterogeneity, providing increased density and dispersion of the crystal structure in all areas of the cast workpiece, including small cross-section [10,[13][14][15][16][17][18]20].…”

The problem of increasing the competitiveness of technology today is largely determined by the quality of manufacturing large-sized cast billets for their supporting systems. Many factors are involved in forming the service properties of a casting. Each factor is important and affects the quality of the resulting casting. The presence of "cold" slag does not allow refining processes to be fully realized during the induction melting of steel. Therefore, attempts to achieve the same results for induction melting steel without additional furnace treatment as for electric arc melting steel do not always lead to success. In recent years, various methods of out-of-furnace steel processing have been developed, which make it possible to eliminate certain disadvantages of induction melting. One of them is the modification of steel in the bucket with rare earth metals (REM). Additional modification of steel in the ladle along with REM also allows for further improvement of steel quality. Currently, REM, with a high affinity for oxygen, sulfur, nitrogen, non-ferrous metals, and other impurities, are widely used in the steel production. Studies have been carried out to improve the technology of out-of-furnace steel processing and its mechanical properties. The effect of alkaline earth and rare earth master alloys on impact strength and the contamination index with non-metallic inclusions of cold-resistant steel is shown.

“…The knockout of the mixture was mainly evaluated by many experts on the compressive strength of the samples, first heated to high temperatures and then cooled. However, many works do not explain the reasons for the chosen heating temperatures, i.e., does not explain the increase in the samples' strength when preheated to one temperature and the change in strength when heated to another temperature [7][8][9][10].…”

The article presents the technology for manufacturing molding and core sands for producing synthetic cast iron and also describes the scheme of the molding-pouring line. The composition and properties of core mixtures are reflected. Shows the process of preparing the molding sand using a mixing runner.The relevance of the topic lies in the fact that the increase in cargo transportation in the world places increased demands on cast iron used to manufacture railway parts and sets new challenges in the field of metallurgy, while reliability and durability are the most important of them. The fulfillment of these requirements determines the competitiveness of products in the corresponding segment of the railway transport market.
