The raw materials for cemented carbide 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 wear degree of mining tools is different, and the average grain size and cobalt content of WC are also required to be different. Today, let’s take a look at the types of cemented carbide geological mining tools and their outstanding advantages.
In addition to the high purity of the raw materials, the materials of cemented carbide for mining are generally coarser in WC and Co particles, 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 molding 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. Rock drilling tools are subject to complex effects such as impact and wear, and the working conditions are harsh. There are at least four types of wear in mining rock drilling, namely: thermal fatigue wear, 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 is not reduced.
As a common part of mining tools, carbide-toothed drills can replace 4 to 10 steel-toothed drills, and their drilling speed is doubled. Perforation rate. For cemented carbide tooth drill bits, the teeth are required to adapt to various rock characteristics, fast perforation speed, wear resistance, and impact resistance, so as to achieve long service life. The down-the-hole drill has become the main tool for high-efficiency perforation. At present, cemented carbide geological mining tools have broad prospects for perforating 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, and the straight drill bit is a widely used high-efficiency drilling tool in changing rock formations. The cross-shaped bit alloy sheets are vertically welded to each other, and it is suitable for drilling soft or broken rocks. The X-type drill bit has a higher drilling speed, a rounder piercing hole, and a tapered connection and a threaded connection, which can be used for mechanized drilling.Click here for more details on KoneCarbide.
