Title:
METHOD FOR COMPOSING STEEL MEMBER AND ALUMINUM CASTING
Document Type and Number:
Japanese Patent JP2979492
Kind Code:
B2
Abstract:
PURPOSE: To easily manufacture a composite member by forming a layer of low melting alloy, etc., depositing with an aluminum alloy on the surface of a steel member, covering the part of the steel member in contact with molten metal with a heat insulating material, impressing high pressure after pouring the molten metal and simultaneously composing the heat insulating material and the steel member.
CONSTITUTION: The galvanized steel plate 1 is directly put on a lower die of a die for high pressure casting for tableware with the galvanized surface turned up. Then mat-shaped alumina fibers are covered over the steel plate as the heat insulating material. The molten aluminum alloy is poured into the die to cover the heat insulating material. Thereafter, the high pressure is immediately impressed to this molten metal to solidify the molten metal, then a casting is taken out by opening the die. In this process, the aluminum alloy exposing one side surface of the thin steel plate 1 and having the alloy layer 2 of the low melting alloy and the aluminum and the layer 3 composed with the heat insulating material and the aluminum alloy can be cast. By this method, the aluminum-made tableware for electromagnetic cooking and the kitchen utensil can easily be manufactured.
