Abstract
Process for the manufacture of abrasive material in which (1) an abrasive mix is brought to fusion as in an electric arc furnace, (2) a relatively cold substrate is dipped into the molten material whereby a layer of solid abrasive material is quickly frozen (or plated) on the substrate, (3) the plated substrate is withdrawn from the molten material and (4) the solidified abrasive material is broken away from the substrate and collected for further processing to produce abrasive grain.
Claims8
An abrasive product consisting essentially of a thin plate of abrasive material having an ultra-fine crystal size, orientation and structure, said material being highly uniform throughout the thickness of said plate and being prepared by
- (a) melting an abrasive mix containing aluminum oxide and zirconium oxide in a stationary electric arc furnace,
- (b) removably positioning a cool substrate material in the melted mix in the furnace for a predetermined time period to deposit a coating of solidified abrasive material on said substrate,
- (c) withdrawing the entire substrate and the solidified coating from the melt, and
- (d) removing the solidified abrasive material from the substrate.
