Cemented carbide teeth are composed 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 cut-off teeth.
Excellent carbide teeth can be used for a long time with less frequent replacement and low chance of failure, which can improve the productivity and increase the efficiency of rotary excavator. So we all pursue high quality carbide cut-off teeth, today we will talk about how to optimize carbide cut-off teeth from the process and manufacturing aspect.
In the process of manufacturing, we should strictly follow the relevant design requirements to ensure that the dimensions between the tooth holder and the cut-off teeth match each other, so as to ensure that the carbide cut-off teeth can rotate freely and flexibly in the corresponding tooth holder and avoid the phenomenon of partial grinding during the operation of the cut-off teeth, which can also ensure the sharpness of the cut-off teeth and thus ensure the realization of the self-sharpening function.
Using the cemented carbide cut-off teeth alloy head overlay welding process, choose wear-resistant wire with relatively good wear resistance and plasticity, and overlay three layers of wear-resistant layer at the weld seam between the cut-off tooth body and the alloy head. The base body is protected from wear. In the overlay layer, the carbide size is greatly reduced and the carbide distribution per unit area is more dense, so when subjected to impact load, the impact force on a single carbide will be significantly reduced, and therefore the impact resistance of the entire overlay layer will be significantly improved.
Using the above methods to optimize the carbide cut-off teeth can make the cut-off teeth can play a good role in the specific operation process, and provide a favorable technical guarantee for the smooth implementation of coal mining work.
The market growth of rock drilling tools using cut-off teeth and ball teeth is slow.
Rock drilling tools, a mining and geological tools, belong to a kind of construction machinery, mainly refers to the tools that can be used to drill and drill the gun on the rock (or ore). Rock drilling tools products mainly include tooth wheel bits, diamond core bits, submerged drilling tools, etc.
Three tooth wheel bits are one of the representative products of rock drilling tools, which are commonly used in mining, oil drilling, infrastructure construction, etc. QYReserch forecasts that the global three tooth wheel bits market size reached USD 3.343 billion in 2020 and is expected to reach USD 4.056 billion in 2027, with a CAGR of 2.8% (2021-2027).
The use scenario of mining carbide tools is mainly mineral resources mining, oil and coal-based energy mining and infrastructure construction, and the industry market size is influenced by the amount of mineral resources and energy mining, and the amount of infrastructure construction input. since 2010, the global iron ore mining overall growth trend, the increase in iron ore mining, driving the market demand for mining carbide tools, further According to BP World Energy Statistical Yearbook, the overall trend of energy mining, mainly oil and coal, is on the rise, pulling the development of mining carbide tools market; in addition, the national "Belt and Road" and other infrastructure construction year by year, providing new development opportunities for the industry.
