Product Description

Detailed introduction:  ferrous sulphide ore (iron sulphidefine ore) is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.

Formation of a protective layer 
（1）The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.

4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2 
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2 

400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.

FeS2→FeS + S 
（3） It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).

（4）Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:
