SIMULATION OF THE LIQUID METAL FLOW AT THE END OF A ROTATING CONSUMABLE ELECTRODE IN THE ESR PROCESS

The article presents the process and results of cold modeling of the electroslag remelting process with the technology of the consumable electrode rotation. Optimal rotation speeds for electrodes with different diameters are found

On the Issue of Nitrogen Solubility in Chromium-Nickel Grades of Steels

The article presents a comparative analysis of the solubility of nitrogen in chromium-nickel grades of steels. It is revealed that the existing theoretical calculations on the solubility of nitrogen in chromium-nickel steels can be applied only to austenitic grades of steels

Investigation of the Effect of Dispersion Strengthening of Iron-Carbon Melts on their Resistance to Local Impact

A technological method for obtaining metallic materials by disperse hardening of a crystallizing melt with tungsten carbide microparticles is presented, which makes it possible to produce materials with increased resistance to local impacts with a stable type of destruction.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-33-90101

HARDWARE AND SOFTWARE COMPLEX FOR EVALUATING THE SURFACE ROUGHNESS OF SUBSTRATES

The necessity of developing a software and hardware complex, which makes it possible to evaluate the surface roughness of ceramic substrates, is described. These substrates will be used in experiments to study the wettability of refractory carbides / oxides and iron-carbon melts

ENGAGING NUMERICAL MODELING TO ANALYZE METALLURGICAL AND CASTING PROCESSES

This theses present the numerical modeling of direct current electroslag remelting process and hardening dispersed carbides injection in centrifugal casting process. The computer soft-ware for modeling this processes has been described

Hydrodynamics of the Motion of the Liquid Droplet of Electrode Metal in the Molten Slag

The results of mathematical modeling of liquid metal droplet hydrodynamics in the slag bath during ESR in the field of centrifugal forces are presented. The size of the bead affects its trajectory, the time of stay in the slag bath and the temperature of heating when passing the slag bath
