Abstract

A continuous process for casting a molten oxide such as an aluminous oxide abrasive is provided wherein two thin metal belts 10, 12 are brought into face-to-face relation and the molten oxide is poured into the nip between the belts as they come into face-to-face relation. The freezing abrasive maintains the belts slightly spaced apart on the order of some small fraction of an inch (e.g. 0.015 cm) and the back surfaces of the belts are flooded with copious quantities of cooling fluid (e.g. water) to maintain the belts below red heat. The belts are held in closely spaced relation for a sufficient time to permit the abrasive to be cooled below red heat. The belts are then separated and the abrasive is discharged from between the belts. At this point the abrasive is no longer affected by contaminants in the air. In a preferred embodiment the top belt can be considerably wider than the bottom belt. <IMAGE>
