During the construction of coal mining and cutting operations, cutting teeth are subjected to immense compressive stress and impact loads, leading to the wearing of the alloy heads and wear-resistant layers of the cutting teeth. Once worn out, the cutting teeth need to be replaced with new ones in order to continue working. As a result, cutting teeth are considered consumables and thus one of the most heavily used mechanical parts in coal mines. So, how can we enhance the wear resistance of cutting teeth effectively?
- Typically, cutting teeth manufacturers employ methods such as thermal spraying, plasma spraying, laser cladding, and overlay welding. Another method that can be used is plasma beam surface metallurgy.
- Brazing and heat treatment are also key technologies to ensure the quality of cutting teeth. Nowadays, brazing and heat treatment of cutting teeth are integrated processes. In this process, the brazed cutting teeth are heated in a vacuum furnace and directly quenched without undergoing air cooling, thus completing both brazing and heat treatment simultaneously.
SKYMECH cutting teeth have been upgraded with alloy composite coatings using a self-developed embedded deep fusion process. This process improves the wear resistance of the cutting teeth by 1.5-2 times, especially in working conditions involving extremely hard rocks.
To ensure the reliability of cutting teeth and improve their performance, it is essential to enhance their reliability and reduce the proportion of coal mining teeth consumption costs. This, in turn, effectively increases the coal machine’s operational time. Strengthening the technological advancements in coal mining teeth can greatly enhance their performance.
