Abstract—For rolling of balls, one of the main parameters for both calculating passes and developing a model for a roll is the roll spacing at the crossing point (zones where the edges of the rolls are as close as possible to each other) in addition to the roll diameter, the roll body length, and the section length. A method is developed to calculate the roll spacing at the crossing point. The calculation results are used to analyze and choose rational tuning parameters of rolls for rolling balls at the EVRAZ NTMK ball-rolling mill. The analysis is carried out on new rolls and rolls after the first, second, third, and fourth remachining of screw ball-rolling grooves. The data are systematized to plot point curves for tuning indicators, and the graphical data are used to make a polynomial approximation. Equations are derived for the functions of the tuning parameters.
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.
