AbstractMetallographic studies of annealed medium-carbon steels (45, 40Kh, and 35KhGSA) showed that there is low-temperature peritectoid carbide transformation of pearlite of these steels, in which solid solutions of ferrite and cementite form solid solution with a broad homogeneity range on the basis of ε-carbide Fe2C. It was suggested to plot the...

AbstractIt was established that the completion degree of the processes that accompany the iron ore pellets annealing on conveyor machines depends largely on the layer’s internal heat source distribution over separate zones. And the most significant role is played by the magnetite oxidation and carbonate dissociation. During the industrial research ...

AbstractThe paper outlines the process of developing a computer model to predict particle distribution during centrifugal casting using the ANSYS FLUENT 16.0 software module. There are several mathematical models developed to predict the volume distribution of particles. The majority of the models is based on a steady state assumption: these are mo...

AbstractThe formative patterns of gaps between turns of cold-rolled strips in rolls and the ways these gaps affect the stress-and-strain state (SSS) of these rolls are disclosed. The effects of surface roughness, temperature, physical mechanical properties, strain degree, and hardening of cold-rolled steel on the interturn gaps in and the roll’s SS...

AbstractThis work discusses the influence of external impact upon pouring of high strength alloyed steel into thin walled molds with external cooling and in the same molds with suspension pouring: complex impact on hardened casting. Selection of these technologies is substantiated. The casting produced in a 3D liquid glass mold was used as referenc...

AbstractA review of techniques for recycling dispersed waste of ferroalloy production is conducted. The formation and accumulation of cyclone dust (catch product of crushing or CPC), formed during the grinding and fractionation of ferroalloys is considered. The drawbacks of the known techniques of handling this dust are shown. The possibility of ob...

AbstractAnalysis of product quality after metal processing by pressure often showed that one cannot obtain high quality surface using cold rolling, running, dragging and other similar processes. It is related to the tool-billet interaction optimization without considering variable friction along with transient wave and auto-oscillatory processes. T...

AbstractThe possibility of ferrite-pearlite banding elimination and obtaining a dispersed and homogeneous ferrite-carbide structure in controlled rolling steels by means of an additional annealing of plates or finished pipes at subcritical temperature values is discussed. It has been found that the regulation of controlled rolling modes and the add...
