Cut Stress Ring to Measure Residual Stress of Roll

Abstract:

Choose ductile cast iron and chilled cast iron, bainitic cast iron three kind of roll materials, respectively, after different heat treatment process, on the roll body interception stress ring specimen, determine the roll internal residual stress. Theoretically proved that the stress ring specimen stress calculation formula is derived. Determine the stress components that exist in the roll. Test results show that the effect of processing condition to eliminate stress. Residual stress in the roll in different material and different heat treatment states difference is larger.
