Title:
PRODUCTION OF COMPOSITE CASTING
Document Type and Number:
Japanese Patent JPS5933064
Kind Code:
A
Abstract:

PURPOSE: To produce inexpensively a composite material having an optional shape and size, by casting molten metal and carbide powder having the specific gravity larger than the specific gravity of the molten metal into a casting mold and making only the composite phase of the composite phase with the metallic phase generated by a difference in specific gravity into a product.

CONSTITUTION: Carbide powder P is charged from a charger 7 into a hopper 4, and molten metal M' is charged from a ladle 6 into the hopper 4, from which the powder and the molten metal are cast into a casting mold 1 consisting of upper parts 1.1 and a lower part 1.2. Since the particles P have the specific gravity larger than the specific gravity of the molten metal M', a casting body C consisting of a metallic phase part C.1 and a composite phase part C.2 is formed in the mold 1. Such body C is removed and is cut along a line (a) to make the composite phase part into a product. The casting weight ratio between the metal M' and the powder P is set at (2:1)W(5:1) and the volume ratio between the metal M' and the powder P of the composite phase part C.2 at (1:1)W (1:3). Iron or the like is used for the metal M' and WC, W2C, etc. are used for the carbide P.
