First, according to the specifications, size, shape and other requirements of the required nuts, the overall structure of the four-station tungsten carbide nut mold is designed, including the specific functions and shapes of each station. For example, some ...

The carbide mold itself has the characteristics of hardness and brittleness. If it is used for large-surface shrinkage and drawing, it is easy to cause the mold to break and scrap due to the stress it can withstand. Even the best mold will be damaged and fail under long-term work and high temperature. If the mold su...

1. Raw material preparation: • Powder selection: Select tungsten carbide powder and binder powder. The binder is usually cobalt powder (a small amount of other hard phases or alloy elements can also be added as required). The particle size, particle size...

Safety in production has a positive impact on the quality of cemented carbide production in many aspects. Only by ensuring safety in production can high quality, high efficiency and sustainable development of cemented carbide production be achieved.Emphasize the correct operation methods of tungsten carbide sinterin...

YG15 and YGH30 cemented carbides have high hardness and can withstand high pressure during cold rolling without deformation. This helps to ensure that the rollers maintain good shape accuracy during long-term use, thereby ensuring the dimensional accuracy and surface quality of the cold-rolled products.

• High hardness and high strength: The hardness of cemented carbide material is much higher than that of ordinary steel, which makes the mold have strong wear resistance and deformation resistance, and can maintain good precision and stability during long...

Metallographic testing is a method for observing the metallographic microstructure of tungsten material products, involving a metallographic method for observing the microstructure of tungsten products by chemical corrosion. It includes grinding, grinding and polishing the surface of tungsten material products.Metal...

• Main metal content: For example, for tungsten carbide cobalt cemented carbide, it is necessary to ensure that the content of tungsten carbide and cobalt is within the specified range, because the ratio of these two main components directly affects the performance of cemented carbide.

Tungsten carbide hot forging die use steel and other materials as the matrix or supporting structure of the mold. These materials should also have good mechanical properties and thermal stability, and can work well with cemented carbide. The selection of steel...

The roll is a component that directly TC Rollscontacts the rolled material and causes it to undergo plastic deformation. Its surface quality, dimensional accuracy and material have a great influence on the quality and accuracy of the rolled product. For exampl...

The Tungsten carbide cold heading process of stainless steel screws requires that the tungsten carbide cold heading die has sufficient strength to ensure the forming accuracy and quality of the screws. The high hardness and high strength characteristics of the carbide die just meet this requirement.

The room temperature hardness of cemented carbide can reach 86-93HRA (equivalent to 69-81HRC), which is much higher than that of ordinary metal mold materials. This enables the mold to resist the wear and scratch of the workpiece material during use, maintain good shape and dimensional accuracy, and can easily cope ...
