Carbide geological mining tools

Time : 2024-02-29 Hits : 6

The raw materials for making cemented carbide geological mining tools are basically WC-Co alloys, and most of them are two-phase alloys, mainly coarse-grained alloys. Often depending on the different rock drilling tools, rock hardness, or the wear degree of mining tools at different parts of the drill bit, the average grain size and cobalt content of WC will be required to be different. Today let’s take a look at what types of carbide geological mining tools there are and what their respective outstanding advantages are.

The material of mining cemented carbide requires high raw material purity, WC and Co particles are generally coarse, and there are strict requirements for WC total carbon and free carbon. Carbide geological mining tools have formed a relatively stable and mature production process. Paraffin is commonly used as a molding agent for vacuum dewaxing (and hydrogen dewaxing) and vacuum sintering.

 

Carbide geological mining tools are responsible for important tasks such as engineering geology, oil exploration, mining and civil construction. Carbide geological mining tools are traditional mining rock drilling tools. Rock drilling tools are subject to complex effects such as impact and wear, and the working conditions are harsh. There are at least four forms of wear in mining rock drilling, namely: thermal fatigue wear and impact wear. , impact fatigue wear and abrasive wear.

 

Compared with general geological mining tools, cemented carbide geological mining tools have higher hardness, strength and toughness. Carbide can better adapt to changing rock drilling conditions, and the wear resistance of the alloy is further improved without reducing the toughness.

 

As a common component of mining tools, carbide-tooth drill bits can replace 4 to 10 steel-tooth drill bits, and their drilling speed is doubled. At the same time, carbide-tooth drill bits require less drill bit replacement, which improves production efficiency. Perforation rate.

For cemented carbide tooth drill bits, the teeth are required to adapt to various rock properties, have fast penetration rates, be wear-resistant, and impact-resistant, so as to achieve long service life. Carbide gear cone drill bits and down-the-hole drill bits have become the main tool for efficient drilling. At present, cemented carbide geological mining tools have broad prospects for drilling holes in large and medium-sized open-pit metal mines, especially large-scale non-ferrous metal open-pit mines.
