Product Description
ø9-21mm Cemented Carbide Buttons With Hardness More Than 90 HRA For Rock Drilling Under Low Air Pressure
Features:
The JK10.2 Grade of carbide buttons are mainly used in the application of quarrying, excavating, water well drilling, and even applied for oil & gas industry, such as Tricone Bits, percussion Bits, etc. All of our products are made of 100% virgin materials - powder of tungsten carbide and cobalt. The average grain size is between 1.6 to 2.0 um, with hardness ranging from 89.5 to 90.5 HRA.
The bullet shape carbide buttons are common type in drilling domain, it supplies good compressive strength, and relatively high impact strength. Generally, two types are used ordinarily. The ball-shaped ones are higher in compressive strength and wear resistance properties, are mostly used in hard rocks. The parabolic shaped ones have high excavation efficiency, are usually used in medium hard conditions. The main physical properties are as follows:
| Grade | Cobalt | Coercivity | Density | Hardness | TRS | Grain Size |
| JK10.2 | 5.2-6.0 | 11.2-13.0 | 14.86-15.05 | 89.5-90.5 | 2750-2850 | 1.6-2.0 |
Products:
The carbide buttons pressed out on shelf waiting for next process - sintering.
The bullet nose carbide buttons blanks without sintered.
The carbide button on the pallet before sintering process.
Blanks before sintering process on the shelves.
Workshop:
The grinding process of the raw materials mixing in the Ball Mill Workshop.
TAP press machine is used for carbide blanks‘ consolidation moulding.
Sinter furnace during the quick cooling stage, the temperature goes down from more than a thousand Celsius to three hundred.
HIP sinter furnace under work in the workshop of HIP sinter furnace compartment for carbide buttons sintering.
The sintering furnace is under working-vacuum sintering with 1360 Celsius.
The HIP Vacuum Sintering Furnace is under working by Ar air protection.
