Cemented Carbide Geological Mining Tools

The raw materials for the production of high-quality alloy geological mining tools are basically WC-Co alloys, and most of them are two-phase alloys, mainly coarse-grained alloys. Often according to different rock drilling tools, different rock hardness, or different parts of the drill bit, the degree of wear of the mining tools is different, which requires different average WC grains and different cobalt content. Today, let’s take a look at the types of cemented carbide geological mining tools and what are their outstanding advantages.

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

Cemented carbide geological mining tools are responsible for important tasks such as engineering geology, oil exploration, mining and civil construction. Cemented carbide geological mining tools are traditional mining rock drilling tools. The rock drilling tools are subject to complex effects such as impact and wear. The working conditions are harsh. There are at least four types of wear in mine 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. Cemented carbide can better adapt to changing rock drilling conditions, and the wear resistance of the alloy is further improved under the condition that the toughness does not decrease.

Tooth bits are a common component of mining tools. Carbide tooth bits can replace 4 to 10 steel tooth bits. The drilling speed is doubled. At the same time, the number of times the carbide tooth bit is replaced is less, which improves production efficiency. Perforation rate. For cemented carbide teeth drill bits, the teeth are required to adapt to various rock characteristics, fast perforation rate, wear resistance, and impact resistance, so as to achieve a long service life. Carbide tooth roller drill bit down-the-hole drill bit has become the main tool for high-efficiency piercing. At present, cemented carbide geological mining tools have broad prospects for piercing and down-hole drilling of large and medium-sized open-pit metal mines, especially large-scale non-ferrous metal open-pit mines.

Cemented carbide drill bits are also one of the cemented carbide geological mining tools. There are many types of cemented carbide drill bits. The inline drill bit is a widely used high-efficiency drilling tool in changing rock formations. The cross-shaped bit alloy pieces are welded perpendicular to each other, which is suitable for drilling soft or broken rocks. The X-type drill bit has a higher drilling speed, a rounder piercing hole, a taper connection and a threaded connection, and can be used for mechanized drilling.
