Calcined corundum abrasives advantages

1, the elimination of the aluminum oxide abrasive abnormal expansion: As in the smelting process of fused alumina abrasive containing low-cost titanium (Ti 0, TiO) and titanium carbide, titanium nitride (Tic, TiN), their 1000% to 900% of a calcined in an oxidizing atmosphere, it will further oxidation, the volume increases accordingly, the volume change of the abrasive itself beyond its normal expansion, the expansion is abnormal.
Abnormal expansion of the abrasive, the ceramic corundum grinding wheel causes the firing, the surface mesh cracks, resulting in a large waste, and the use of calcined aluminum oxide abrasive to eliminate anomalous expansion of the most effective means.
2, to improve the toughness of the aluminum oxide abrasive and grinding performance: The study found, this is due to the abrasive in the calcination process, the first corundum crystalline solid melting at the TI3 + is oxidized and cause contraction of the lattice, thereby increasing the abrasive resistance compressive strength, followed by calcination in the granulation process will make the internal stress caused.
Thus, after calcination produces a variety of abrasive grinding tools, not only durable and sharp increases abrasive grinding performance.
