Determination of Particular Relative Reduction in Cold Rolling of Thin and Extra Thin Strips to Implement the Process with the Least Force

Introduction. It has been theoretically established and experimentally confirmed that the elastic deformations of rolls strips in cold rolling have a significant and, case thin rod rolling, crucial effect on all process parameters.Problem Statement. The influence elastic-plastic interaction strip with rolls, tension, temperature rate deformation, strength material shall be taken into account for developing modern theory longitudinal rolling.Purpose. Modeling forecasting parameters extra strips.Materials Methods. To solve this problem, conditions made 08kp steel different degrees preliminary metal hardening, which reflected features regularities hardening multicellular state line, modeled. partial relative reductions vary within 0.02—0.35,with initial data corresponding to most characteristic operating mills taken.Results. quantitative thickness, at entrance deformation zone, reduction during least force. For first time, range force determined. unriveted pre-hardened steel, varying rangefrom 0.1 0.30—0.35 provides realization force.Conclusions. implementation is advantageous terms energy saving manufacturability, as it allows reducing specific consumption electricity expanding smaller thicknesses indicates need determine conditionsfor such process.
