New series of torches for hardening “DONMET” 227

The design-engineering bureau of “DONMET” plant at the request of PRAO “Zaporozhkran”, Ukraine, has developed a new series of torches for hardening “DONMET” 227.

The torches are designed for hardening the rolling surface of travel wheels with a diameter of 250 up to 820 mm.

  • work on a mixture of oxygen and natural gas (methane);
  • a wide range of standard sizes of heads for wheels of different sizes
  • an economically viable alternative to hardening via high-frequency current
  • water cooling of the head to prevent overheating during prolonged operation.

For higher efficiency, the torches can be used in sets of several torches simultaneously.
