The correct choice of carbide mining tool grade is one of the most important factors in ensuring the effective use of carbide.
In the selection of carbide grades, for very hard rocks and impact power of heavy rock drills should focus on the toughness of the alloy, choose a higher cobalt alloy grade; for hard and brittle, and corrosive rocks, should focus on the wear resistance of the alloy, choose a slightly lower cobalt alloy grade; for medium-hard and medium-hard rocks below, should choose a lower cobalt content, higher hardness alloy grade; for heavy-duty use under the The main use of mining carbide for coal miner's cut-off teeth is to reduce the cobalt content and improve the grain size so that the bending strength and impact toughness of the alloy can be greatly improved; for pillar teeth, crosses and three edged brazing heads, the carbide with lower cobalt content is used. The following points should also be noted.
1.The physical and mechanical properties of the rock formation, such as hardness, friction, etc. and its shape characteristics. The principle generally adopted is that the harder the rock being chiselled, the better the toughness of the chosen alloy piece should be, but not too soft. Note that the wear resistance should not be too low, as too soft will increase the consumption of the alloy and at the same time reduce the efficiency of the chiselling. For rock formations with many cracks, regardless of their hardness and the type of rock drill used, a cross-shaped bit should be used.
2.The type of rock drill, e.g. light, heavy, etc.
3.Method of breaking the rock (cutting, shearing, crushing, striking, etc.)
4.Equipment capacity (high or low wind pressure)
Hunan Jetvision Industrial Co.Ltd offer kinds of tungsten carbide products for mining, such as carbide button, carbide insert for mining, carbide coal button, carbide PDC substrate, etc. With top quality and low factory price.
Tungsten carbide components manufactured by Hunan Jetvision for the drilling and mining industries. Tungsten carbide may be strong, but it can also be pressed into various shapes and sizes. The hard compound is mixed with binding agents and then pressed with a high amount of pressure and heat to take the required shape.
How is tungsten carbide mined?
Open-pit mining methods are used when the tungsten minerals are found in the earth's surface, not requiring digging underground. The areas where open-pit mining occurs are usually referred to as quarries. These quarries or large pits are expanded until no more useful minerals can be extracted.
Where can I find tungsten carbide?
Tungsten Carbide is an inorganic chemical compound (WC) containing equal parts of tungsten and carbide. Its most basic form is that of a fine grey dust and is generally mined in China
When do We Need Carbide Button?
Carbide buttons are used in a wide range of applications in cutting tools and mining machinery, road maintenance and coal mining tools. Cemented carbide insert are used in mining as quarrying and mining tools as well as in tunnels and civil construction. Carbide button are so versatile that they are a key component in carbide manufacturers' production.
