Abstract
Methods,characteristics and research progress of on-line heat treatment process for U75V steel rail with 100-meter length were summarized.Effects of heat treatment cooling process parameters and spray cooling process parameters on the production efficiency,microstructure and mechanical properties of the heat treated U75V steel rail with 100-meter length were introduced.Suggestions for future research on the heat treatment process of pearlite rail with 100-meter length were proposed.It is meaningful to study the effect of cooling process parameters on the microstructure and mechanical properties of the steel rails,with the goal of shortening the required heat treatment cooling time,and optimize them.Reducing the allowable fluctuation range of alloy composition content is beneficial for improving the properties of the U75V steel rail in combination with the optimization of heat treatment process.A nozzle or air spraying process that combines heat transfer capability and uniformity is beneficial for optimizing the heat treatment process of the steel rails and improving their properties.
