Essay

The process of cold-rolled strips. Developed and recommended ways of rolling strips in areas with transient heating of end stations, reducing the pressure in the hydraulic balancing devices, and in the non-rolled rolls. Experimental studies were carried out on cold-rolling mill NSKHP 1680, the camp in 1700, 650 and 600 of "Zaporizhstal". The regularities of changes in the terminal thickening bands, depending on: the coefficient of friction, the flow stress of the metal, speed and temperature, strain, strength, balance the work rolls. Established new patterns of change in the average normal contact stress, the kinematic parameters of the rolling process with a drive roller and the N-rolls. Changed the established notions of minimal impact on the friction force in the non-rolling rolls. Embedded item. Metallurgy and manufacture of cold rolled strips.
