How to control the carbon content of carbide ball reasonably?

Tungsten Carbide ball, also known as tungsten steel ball, carbide ball, is a ball or bead made of tunsgte carbide alloy. It had wide application, such as: all kinds of instruments and meters, water pumps, sealing valves, oil fields, configuration, finishing and so on. Because of the wide range of applications, we have put forward higher technical requirements for cemented carbide ball materials, and carbon content is one of the important factors affecting the properties of alloy ball. So how to reasonably control the carbon content of cemented carbide ball?

Method 1:

In the process of mixing, a small amount of carbon black is added to the powder to achieve the purpose of carburizing, but it is easy to cause carbon segregation during wet grinding and abnormal growth of WC grains during sintering.It can also adjust the amount of glue in the process of mixing the forming agent to control the degumming process in the sintering process so as to meet the requirement of carbon control.

Method 2:

W powder is added in the batching to control the total carbon of the mixture. This method has the advantages of simple process, good process stability and no special requirements on the forming agent and sintering equipment. It is an effective method to produce high-quality cemented carbide balls with stable quality.

Method 3:

Add a small amount of two-phase zone broadening agent to the powder, such as TAC, TiC, NbC, Ni, etc.It can reduce the sensitivity of cemented carbide spheres to carbon content, and rare earth will also affect the carbon content of cemented carbide spheres, because rare earth will exist in the alloy as Re2C3, adding rare earth will reduce the effective carbon content of the alloy.

In order to reasonably control the carbon content in the tungsten steel ball, the above methods are usually used in the powder preparation of ordinary alloy ball.
