Estimation of Deformation Site Parameters for Symmetric and Asymmetric Rolling of a Strip Using Computer Simulation
Computer simulation of longitudinal rolling is performed for different combinations of the diameters of the upper and lower rolls: 600–600, 590–600, 570–600, and 300–600 mm. The rolling for each variant of combinations of working roll diameters has been carried out in three passes (the initial strip thickness is 2 mm; the gap between the rolls is 1.4 mm in the first pass, 0.98 mm in the second pass, and 0.66 mm in the third pass. The methods have been proposed for determining the lengths of the arc of contact and of the actual deformation site, and the lengths of external zones have been estimated.
期刊介绍:
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
