Influence of rail grinding process parameters on rail surface roughness and surface layer hardness

摘要

An important part of rail maintenance is rail grinding. To ensure an economically reasonable rail life cycle and to extend the time period between repair tasks, grinding processes should not induce damage in rails, such as cracks or an increase in hardness. On the other side, high productivity of rail grinding, which tends to induce damage, is crucial to reduce repair disruptions and delays.
