Tungsten carbide round bars are materials made from metal elements such as cobalt, tungsten, carbon, and carbides through high-temperature sintering, possessing high hardness, wear resistance, and corrosion resistance. In the industrial field, tungsten carbide round bars are widely used in cutting tools, grinding tools, stamping molds, and other areas.

The processing technology of tungsten carbide round bars mainly includes the following aspects:

1. Raw material preparation: First, high-quality tungsten carbide powder and other additives need to be selected, and then mixed evenly according to a certain ratio. The mixture is then pressed into a blank with a certain shape and size.

2. Sintering: The blank is placed in a high-temperature sintering furnace for sintering treatment, allowing the metal elements and carbides to react fully, forming a dense tungsten carbide material. The control of sintering temperature, holding time, and atmosphere has a significant impact on the final material properties.

3. Precision machining: The sintered tungsten carbide round bars need to undergo multiple precision machining processes, including turning, milling, grinding, etc., to ensure their dimensional accuracy and surface quality.

4. Surface treatment: The surface of tungsten carbide round bars usually requires coating treatment, with common coatings including TiN and TiCN, to enhance their wear resistance and corrosion resistance.

5. Heat treatment: The final performance of tungsten carbide round bars can also be further improved through heat treatment, with common heat treatments including tempering and low-temperature annealing.

In addition to the main processing technologies mentioned above, tungsten carbide round bars may also require other customized processing technologies depending on the application field to meet specific needs.

In summary, the processing technology of tungsten carbide round bars is a comprehensive process that needs to combine the characteristics of the material and application requirements, using appropriate processing methods and equipment to ensure that the final product's quality and performance meet the requirements. During the manufacturing process, attention should be paid to controlling process parameters and quality control in production stages to ensure the processing quality and yield of tungsten carbide round bars.
