Straightness of U75V 100m Heavy Rail under Deferent Straightening Processes
Temperature of the head, the waist, the bottom and angle of the bottom of same heavy rail lying on the cooling bed is tested continuously, time interval is 5min, which can provide the basis for prebending process. Additionally, the U75V 60Kg/m heavy rail straightening processes using the horizontal and edge roll compound straightening machine is discussed in this paper, and contrasts the cross-section dimension and straightness of heavy rail before and after being straightened, which is important to make certain of optimum straightening parameters.
