Product Description
ø9mm Tungsten Carbide Silver Gray Buttons For Low Air Pressure DTH, Rock Drilling In Medium Hard Rock Layers
Features:
This type of button, usually called bullet nose (BN) buttons, are mainly used in quarrying, excavating, water well drilling, and oil & gas industry. It has been made of fine grain size of raw material-mixture of tungsten and cobalt powders and 100% virgin materials. 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 can be divided to ball shape and parabolic shape. The ball-shaped ones have good compressive strength and wear resistance properties, and suited to mostly hard rocks. The parabolic shaped ones are relatively good compressive strength, usually used in medium hard conditions, but has high excavation efficiency. 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 not be sintered on the shelves.
Workshop:
HIP sinter furnace with tons of capacity in a month
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.
