Characteristics of carbide Button

What is tungsten carbide button?

Tungsten carbide button is a kind of alloy material with high hardness and high strength, which is made of tungsten carbide powder as the main raw material, plus other precious metals and bonding powders, which are pressed and sintered by metallurgical methods.

One end of the cemented carbide button is a ball head (working part), the other end has a 18° chamfer, and the middle is a cylinder. It is mainly used for inserting ball tooth drill bits. The carbide ball tooth adopts centerless grinding technology with high dimensional accuracy, which is convenient for users to carry out precise welding and is not easy to drop teeth. The buttons are pressed into the hole of the drill with an interference fit, and once in, cannot be removed, ensuring the effectiveness of the drill. Typically, each drill requires a total of 20 buttons including 10 side teeth and 10 middle teeth.

With the development of the petroleum industry, the demand for oil well drilling tools has also greatly increased, especially the cemented carbide buttons.

Material of tungsten carbide button

Tungsten carbide (WC) is an inorganic compound containing equal amounts of tungsten and carbon atoms. In layman’s terms, tungsten carbide is usually referred to simply as carbide. In its most basic form, it is a fine gray powder, but it can be pressed into shapes for use in industrial machinery, tools, and abrasives.

In 1923, Germany’s Schrotter added 10% to 20% cobalt to tungsten carbide powder as a binder, and invented a new alloy of tungsten carbide and cobalt. The hardness is second only to diamond, which is artificially produced in the world. into the first cemented carbide.

Cemented carbide is a powder metallurgy product made of high-hardness refractory metal carbide (WC, TiC) micron-sized powder as the main component, cobalt (Co) as the binder, and sintered in a vacuum furnace or a hydrogen reduction furnace. .

What are tungsten carbide buttons for?

What are tungsten carbide buttons for?

Carbide buttons are widely used in oil drilling, mining machinery, civil construction, water well drilling, road maintenance, tunnel excavation, cutting tools and coal drilling tools. In addition, it is also used as a drill accessory for heavy rock drills or deep hole drill tool accessories.

1. Carbide buttons are widely used in oil drilling and snow removal, snow plow machines and other equipment.

2. Used for shearer drilling tools, mining machinery tools and road sweeping snow removal and road maintenance tools.

3. Tools used in quarrying, mining, tunneling, and civil construction.

 

According to different oilfield drilling machinery, such as roller cone bits, down-the-hole drill bits and other geological drilling tools, cemented carbide teeth are divided into different standard styles: including spherical teeth, conical teeth, wedge teeth, spoon teeth, flat top teeth, Parabolic teeth, etc. LMM specializes in the production and processing of various types of hard alloy teeth to meet the different needs of customers, and has cooperative supply for cutting tools, oil drilling, cutting tools, mining machinery, road maintenance and coal drilling tools.

What are the advantages of tungsten carbide buttons?

Tungsten carbide button has superior wear resistance and impact toughness, and has a higher drilling speed than similar products. The passivation service period of the button series bit is long, and its non-grinding life is about 5-6 times of the grinding life of the bit with the same diameter, which is conducive to saving auxiliary working hours, reducing physical labor and speeding up the project.

Our product advantages:

1. High wear-resistant and durable made of raw materials

2. Overpressure sintering to increase the density of alloy teeth

3. Quality Assurance

4. Can be customized according to customer requirements
