Alloy steel composition frog

Alloy steel composition frog features:

1.Alloy steel centre rail of high mechanical strength, good toughness, and wear resistant;
2.A whole of life of more than 2 million tons total weight;
3.The frogs can be welded to rail lines;
4.The resulting alloy steel combination frogs meet the seamless line joint requirement between each crossing.

  Alloy steel combination turnout has been used for many years by the majority of users who welcomed its superior whole of life performance of more than 2 million tons total weight. In up to 2 million tons of lifetime use, wing rail wear caused by frog and frog damage is the main reason for replacement. As the structure requires a wing tip to central track rail width dimension of 50, the friction loading is very high, and the wear down is concentrated in the triangular area shown. This results in gauge wear, and directly affects the frog life and the smooth passage of the train .
