Cast iron metallography - vermicular nodularization rate

By heat treatment, the long strips of carbide in the iron are turned into granular carbides.

Use a microscope to take a metallographic image (500 times) to calculate the percentage of carbide particles that meet the aspect ratio.

It can also calculate and analyze the depth of decarburization layer after heat treatment.

Spheroidization rate detection software (FOS)Using artificial intelligence methods to improve the accuracy of wire balling rate determination, and based on the principle of simple use and output, it reduces the burden on inspection personnel, improves the yield rate of product wire drawing and plastic processing, also enhances the company's industrial competitiveness, and ensures quality and products Delivery date.

  1. Real-time identification of wire balling rate;
  2. Record the digital spheroidization rate identification results with one click;
  3. One-click output of digital spheroidization rate report;
  4. All identification results can be recorded digitally.

Decarburization layer depth detection software (FOC)Removing human and subjective judgment methods, in accordance with the following international standards, the software intelligent function is used to objectively and accurately automatically determine the depth of decarbonization.

  • The benefits of spheroidization rate software for subsequent processing:
  1. Reduce wire hardness and deformation resistance.
  2. Increase wire ductility and cold forging material formability.
  3. Stable spheroidization rate,Product yield is improved.
  4. Avoid brittle fracture of screws.
  5. Reduced failure rate,Production costs are reduced.
  6. Reduced wear on the drawing die,Production efficiency is improved.
  7. It can effectively enable buyers and sellers to decide on acceptance criteria.
