States existing railway single turnout guide curve radius, mostly circular curve. For the guide curve speed limit basic parameters Hebei coal mine turnout, using the value of the countries are quite different railways. Fixed frog is generally straight, but also curved portion of the guide into the frog form. Germany, France, widely used curved frog. Thus the number of frog numbers in the same conditions, can increase the conductivity curve radius. In the transformation of the existing line of coal mine turnout, widely used in the former Soviet Union 1/11 P65 rail turnouts (fast type) frog mainly high manganese steel casting the entire structure. France except for the high-speed Shinkansen lines are made of high manganese steel frog entire cast coal mine turnout manufacturer to optimize the material and casting process, while improving the design through structural analysis. United States, Britain and the former Soviet Union exploded frog surface hardening. Statistics show that the use, extend the life of 30 to 50%. National Day Research, Austria, France and other high-manganese steel and carbon steel with chrome base by 20mm long media into segments of welding technology.
