A research object is the modes of deformation at the cold rolling of thin bars. A research purpose is an increase of efficiency of the modes of deformation at the cold rolling of thin bars. Research methods are theoretical and experimental researches of the modes of deformation at the cold rolling of thin bars. Theoretical and practical results of research: the numeral and regressive mathematical models of force of the cold rolling of thin bars is developed; on the basis of experimental information the sufficient degree of authenticity of the developed mathematical models is confirmed; the power affecting is analysed bearings of workings rollers; the program is developed for the automated planning of the optimum modes of preloads. Novelty of research results - the developed mathematical models take into account the real character of distributing on length of hearth of deformation of mechanical properties, geometrical parameters, and also coefficient of external friction. Research efficiency: practical recommendations are given for the increase of firmness of bearings of workings rollers; the optimized mode of preloads is developed at the cold rolling of thin bars on a continuous rolling mill. A sphere of the use is continuous and reversible figures of the cold rolling of thin bars.
