Designing and reclaiming of deformation modes on the mill 280 of State Unitary Enterprise "Casting Rolling Plant"(STE CRP), Yartsevo
At designing of deformation modes and engineering of roll grooving for small-section mill 280 established at the STE CRP, the new calculation principle is used, when base circles were set and then, on the specified dependences offered by A.I. Tselikov counted off oval intermediate section by the iteration method. The given result was corrected by adaptive coefficients, which were defined by the practical data. Commercial operation of mill has shown high accuracy of the designed deformation modes. The universal calibration, which allows rolling strips with different geometrical parameters in the same grooves, was developed for reduction of rolls park, and also decrease roll changing quantity.
