Customized Mining Tools Rock Drilling Parts Tungsten Carbide
Buttons
Application
Tungsten carbide is the best material for drill tooth in medium and
high pressure down hole hammer drilling industry.
Tungsten carbide buttons has superior wear resistance and impact
toughness, it has a higher rate of drilling and digging compare
with similar or competing products. The drill bit of tungsten
carbide buttons by passivating treatment has a longer service
cycle, its service life is 5 to 6 times than the same diameter of
drill bit, it is conducive to save unproductive time and reduce
manual labor of workers and speed up the project. Tungsten carbide
buttons mainly used in Oil drilling, snow plough equipment, mining
machinery, road maintenance and coal drill tools, and other fields
for quarrying, mining, and mining tools in tunnel and civil
construction, it also as a drill part for heavy-duty rock drill or
deep hole drill tools parts.
According to different oilfield drilling machinery, such as a cone
bit, down-the-hole drill bit, geological drilling tools, tungsten
carbide buttons is divided into different type: type B, type E,
type P, type Q, type S, type Z and rests.
When used, when choosing tungsten carbide grade for tungsten
carbide buttons, we should according to the characteristic of
material and the working conditions to choose the right grade, to
meet specific application requirements.
Technological process of production of our tungsten carbide
buttons: powder process → formula according to the use requirements
→ wet grinding → mixing → smash → dry → sieving → add binder → dry
again → get the mixture after sieving → pelletize → pressing →
forming → sinter-hip → forming (blank) → blanks checking →
passivating treatment → cylindrical grinding (according to the
customer request) → cleaning → inspection of the finished product →
packaging → entering warehouse.
