Significance of grinding of turnout switch rail

Significance of grinding turnout switch rail;

1. Turnout grinding can eliminate the fat edge and scale damage on the rail top, long and short wave grinding and other damages, especially grinding the point rail and the heart rail, so that the fat edge on the point rail is basically eliminated, the wheel-rail relationship between the heart rail and the wing rail is improved, and the transition of wheels from the point rail to the basic rail and the heart rail to the wing rail is relatively smooth.

2. At the same time, the outline of the rail head can be repaired according to the needs of the site in actual operation. After grinding, it is crushed by the train to form a light belt with a width of 15mm-20mm in the middle of the rail top surface, which can obtain a good wheel-rail relationship, improve the smoothness of the rail in the turnout area and effectively prolong the service life of the turnout.
