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whereby a layer of solid abrasive material is quickly frozen (or plated) on the substrate, (3) the plated substrate is withdrawn from the molten material and (4) the solidified abrasive material is broken away from the substrate and collected for further processing to produce abrasive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.
Claims26
A process for manufacturing abrasive material comprising
- a) melting an abrasive mix in a furnace,
- b) removably dipping a relatively cool object in the melted mix in the furnace for a controlled period of time whereby a portion of the mix solidifies on the object as abrasive material,
- c) withdrawing the entire object and solidified abrasive material from the melted mix, and
- d) removing the solidified abrasive material from the object.
A process for manufacturing abrasive material comprising
- a) melting an abrasive mix containing aluminum oxide and zirconium oxide in a stationary electric arc furnace,
- b) dipping a relatively 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 object.
