Deformation Resistance of Alloy 2.25Cr1Mo0.25V of Heavy Cylinder for Hydrogenation Reactor
Abstract:
2.25Cr1Mo0.25V alloy steel of making heavy cylinder for hydrogenation reactor was taken as research subject. The compression experiment was carried out on Gleeble-3500 thermal simulator under different conditions of deformation temperature, strain rate and deformation degree. The relationship between deformation resistance and deformation temperature, strain rate, deformation degree was analyzed. Two different types (dynamic recovery and dynamic recristallization) of deformation resistance model were established through multiple nonlinear regression method. The relative error of deformation resistance between the calculated value and the measured value was under 10% and the maximum error of the rolling force between the calculated value and the measured value was 9.7%, which showed that this deformation resistant model was accurate and met industry requirements.
