  • A.B.Moller, N.A.Gnevnov. METHODS OF OBTAINING SORBIT STRUCTURE FOR HIGH STRENGTH WIRE RESPONSIBLE PURPOSE.
    Abstract: the paper explored the ways sorbitizing wire rod of high strength and high strength.
    Keywords: rolled wire, air cooling, salt patenting, Complex Water Bath Processing, methods sorbitizing, structure, sorbit.
  • S.A.Levandovskiy, D.I.Kinzin, S.Yu. Sarancha, G.K.Rozhkov. DATABASE OF TECHNOLOGICAL PARAMETERS, AS A BASIS FOR MANAGEMENT OF SECTION ROLLING PRODUCTION.
    Abstract: modern section and wire rod mills of the new generation have got systems for monitoring technological parameters and managing product quality in off-line mode. In order to implement mathematical models of roll pass design and setting up mills on new technological objects, the next result was obtained: developted a digital form of representation of the main technological data such as calibers, rolling modes, equipment parameters and implemented this data in the section rolling production. Based on the developed databases, the regularities of the rolling and adjustment processes for a wide range of profiles in the 450, 370 and 170 mill of OJSC MMK are determined and systematized.
    Keywords: section rolling, database, technological parameters.

    Abstract. Improved the model for prediction of energy-power parameters of rolling thin strips in the finishing group of wide-strip hot rolling mill was improved.
    Keywords: wide strip hot rolling mill, thin hot rolled strip, rolling force, rolling torque, motor current.
  • D.A.Volkova, M.I.Rumyantsev. ANALYSIS OF THE KNOW DEPENDENCES FOR CALCULATION OF TORQUE WHILE HOT ROLLING SHEETS AND STRIPS.
    Abstract. Considered and analyzed are the known approaches to calculating the torque for hot rolling of sheets and strips, as well as some dependencies of the coefficient of the braking force of rolling.
    Keywords: rolling, rolling torque, lever arm coefficient, height of the roll gap, calculation error.
