Effect of toughness on brown corundum abrasives:
If the brown corundum abrasive has a certain toughness, it will ensure its own service life, brown corundum abrasive will be subjected to a certain impact and vibration during processing, and having toughness can make it absorb the huge energy brought by impact vibration, so as to ensure that the abrasive is not damaged, and can be used twice or even multiple times.
At the same time, toughness also has a great impact on the self-sharpening of brown corundum, the stronger the toughness, the less likely brown corundum is to break, but it is easy to passivate, the grinding force is reduced, and the two functions are mutually exclusive. Of course, there is also a measure of the toughness of brown corundum abrasives, which cannot be extended indefinitely, because of the contradictory properties of brown corundum toughness and self-sharpening, so it is necessary to determine the balance of toughness and self-sharpening according to its own needs.
Factors related to the toughness of brown corundum abrasives:
1. The content of alumina, generally speaking, the lower the amount of aluminum, the worse the toughness. But if it is understood that the higher the aluminum content, the better the toughness, then it can be considered that the higher the aluminum content of white corundum, why its toughness is worse, this is not true, so this point is limited to brown corundum.
2. Carbon content, the less carbon content of brown corundum abrasive, the better its toughness, generally low-carbon brown corundum toughness is better.
3. Whether it is fired at high temperature, brown corundum fired at high temperature not only removes a lot of carbon, but also removes a lot of magnetic substances, so the toughness of brown corundum fired at high temperature is very good.
