Mill Hollow Shaft Process Measures:

  • Molten steel secondary refining (R-H vacuum treatment)
  • Modeling using special sand, strictly control the pouring temperature and casting speed
  • Journal processing to ensure concentricity and roughness of the end surface of the mouth

Mill Hollow Shaft Quality Tests :

  • Rough casting mechanical properties and chemical composition(internal standard)
  • Ultrasonic testing after rough machining
  • Ultrasonic testing and magnetic particle testing after finishing
