ANTI-CORRUGATION PROPERTY OF RAIL STEEL

Rolling contact tests using two rollers in a laboratory have been carried out under the conditions of slip ratio 9% and Hertzian contact stress 0.5 GPa with no lubrication in the air in order to evaluate the anti-corrugation property of rail steel. As a result, formation of corrugation wear was confirmed under these conditions. After completion of these tests, deformation and geometry of each specimen were quantitatively evaluated taking fractional dimension as an evaluation scale in relative evaluation. These tests revealed that low-alloy fine-perlite steel, high carbon fine-perlite steel, high-hardness bainite steel, and high-carbon common perlite steel were excellent in anti-corrugation properties in the order named. Furthermore, it has been clarified that corrugation wear formed on a specimen rail and one generated on an actual rail are similar to each other because in both cases formation tendency of corrugation wear and fractional dimensions are almost identical; anti-corrugation property does not linearly depend on anti-wear properties.
