A list of these cemented carbide articles makes it easy for you to quickly access relevant information. We have prepared the following professional cemented carbide, hoping to help solve your questions and better understand the product information you care about.
The hardness of the metal is the ability of the metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator to measure the degree of softness and hardness of the metal material.
The cemented carbide pulse nozzle is based on the principle of self-oscillation, relying on the self-oscillation chamber of the nozzle itself to convert the continuous jet into a pulsed jet, that is, the jet flows into the water chamber from the different flow in the upper section of the nozzle
Cemented carbide forging die is also called forging die. It has good heat resistance and fatigue resistance. It applies a certain pressing force through the closing and closing of the upper and lower dies, so that the forgings have better structure and mechanical properties.
Metal hardness is ability of a metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator of the hardness of a metal material. It can sensitively reflect the chemical composition, metallographic structure, Differences in heat treatment.
The cemented carbide rock drilling teeth violently impact the rock during rock drilling to achieve the purpose of drilling holes in the rock. During this process, the carbide teeth collide and rub against the rock, inevitably causing wear.
If you do not understand the density and influence factors of cemented carbide, it will easily lead to the wrong purchase of cemented carbide. This is a brief introduction of the density and influence factors of cemented carbide.
Cemented carbide sintering is the most basic and critical process in the production process, and it is also the last process. Sintering methods and equipment have a huge impact on the product. Conventional sintering methods include hydrogen sintering, vacuum sintering, hot isostatic pressing etc.
China's cemented carbide ball and drill has large production capacity and global competitiveness. Its production capacity still has room for expansion. The domestic and international markets have good prospects.
In a variety of sintering technology, microwave heating with heating speed, the overall heating, selective heating and non-thermal effects and other traditional heat conduction heating mode does not have the characteristics. Carbide (WC-Co) powder compact has a good coupling absorption effect on mic
