Constructions of cylindrical electric resistance furnaces for hardening heat treatment of metal products of various purposes have been developed. Their characteristics and features are presented.
Keywords: electric furnace, hardening heat treatment, thermal oxidation, oxide covering, functional properties, thermal covering.
Steel casting
- Semicontinuous casting of solid and hollow steel ingots for engineering industry. Anikeev, V.V., 9
The results of launching the technology of semicontinuous casting of steel ingots to produce forged pieces are presented. The data of ingot quality and cost-effectiveness is given.

Quality of metal products
- Influence of impurities in low-hardenability steel on spring plate quality. Karpov, A.A.; Zubarev, M.G.; Vasin, E.A.; Burmasov, S.P.; Belikov, S.V.; Ryzhkov, M.A.; Zhilyakov, A.Yu.; Gudov, A.G.; Kleonovskiy, V.B., 18
Based on metallographic studied, influence of non-ferrous metal impurities as well as sulphur, nitrogen and oxygen on a characteristic of structural transformations during a hardening of spring plates made of low-hardenability steel has been estimated. The study results are presented.
Keywords: low-hardenability steel, impurity, spring plate, hardening rate, structural transformation, austenite, martensite.
Modelling of metallurgical processes
- Electromagnetic and thermal processes in laboratory of super-power arc steel-making furnaces. Part 1. Bikeev, R.A.; Cherednichenko, V.S.; Kuzmin, M.G., 24
Analysis of physical processes in a laboratory of super-power arc steel-making furnaces has been carried out, a onnection of electromagnetic and thermal parameters and their dependence on instantaneous values of operating currents in plasma and in the furnace has been determined.
Keywords: arc steel-making furnace, plasma, arc discharge, current density, electromagnetic process, magnetic field strength, heat exchange, heat flow, simulation.
- Interaction model of components of metal melts and slag systems, taking into account their cluster structure. Venets, Yu.S., 31
A cluster structure of liquid metals and slag systems has been thermodynamically described on an electron level of unit elements. Using the model developed on this base, dependences of nitrogen solubility in steel were studied and dynamic viscosity and electric conduction of manganese ferroalloy systems were calculated.
Keywords: melt, thermodynamics, interaction, component, electron configuration, element, model, cluster structure.
Resource saving
- Remelting features of scrap and aluminum alloy ingots in dc arc furnaces and resistance furnaces. Kolistratov, M.V.; Farnasov, G.A., 38
Various furnaces for utilization of industrial scrap and domestic waste have been studied. The conclusion was drawn that is reasonable to use a combined plant with a resistance and dc arc heating for aluminum-bearing scrap remelting.
Keywords: electric furnace, aluminum alloy, remelting conditions, melting rate, metal yield, skull, carbide.
- Opportunities of intensive energy-saving in electric steel-making process. Platonov, I.V.; Kartavtsev, S.V., 42
Application of the secondary energy- resource, namely liquid steel heat, is useful to melt metal scrap in electric steel-making. Possibilities of melted scrap use in an electric steel-making process are considered.
Keywords: energy intensity, intensive energy-saving, resource-saving, electric metallurgy, scrap metal.
Information materials
- Models of metallurgical processes and systems (based on an international symposium CSSCR 2013). , 46
