AI Technical Summary

Problems solved by technology

The current problem of the reaction casting method is that the content of ceramic hard abrasive in the magnetic abrasive is low and the particle size of the hard abrasive is difficult to control

Although this method solves the problem of poor compatibility between the iron-based phase and the abrasive phase, the magnetic abrasive prepared by this method is subjected to the high temperature of the plasma flame, and the sharp cutting edge of the abrasive grain phase is passivated, resulting in a significant reduction in grinding efficiency. , its grinding ability is even inferior to that of magnetic abrasives prepared by other simple methods
