Cemented carbide coal teeth are made of cemented carbide ball teeth brazed to alloy structural steel and are generally used in coal mining machines to cut and extract coal directly, so they are also called cemented carbide coal teeth.
Do you know why carbide coal cut off teeth fail?
Carbide coal cut off teeth are important parts of rotary drilling machine, some people say that carbide coal cut off teeth fail and are often replaced, which increases the cost of the enterprise. So what are the reasons for the failure of rotary drilling rig cut off teeth?
In rotary excavation, rotary drilling rig carbide cut off teeth in cutting hard strata undergo high periodic compressive stress, shear bending stress, periodic or sudden impact load and thermal stress, wear and other effects, although the hardness of the strata is not high, but often encounter gangue, quartz and other harder ores, cut-off teeth in the use of the process of failure, the main forms of failure are alloy fragmentation, wear and fracture.
The main failure forms of rotary drilling rig cut off teeth are wear and tear and shedding of cut off head. The main reasons for the failure of cut off rock layer teeth are insufficient bending strength of alloy, poor wear resistance of alloy and poor fatigue resistance.
