Title:
METHOD AND APPARATUS FOR CASTING ALUMINUM BY CASTING MOLD
Document Type and Number:
WIPO Patent Application WO/2003/004201
Kind Code:
A1
Abstract:
A method for casting aluminum by a casting mold, which comprises the steps of filling a cavity (25) with an inert gas, introducing gaseous magnesium into the cavity to precipitate a magnesium layer (58a) on the surface of the cavity, heating the surface of the cavity to a predetermined temperature, introducing a nitrogen gas into the cavity to form magnesium nitride (58b) on the surface of the magnesium layer, and supplying an aluminum melt into the cavity having the magnesium nitride formed to thereby produce an aluminum casting while reducing the surface of the aluminum melt (39) with the magnesium nitride. The method allows the shortening of the time required for the formation of magnesium nitride and the reduction of the consumption of nitrogen.
