Document Type and Number:
WIPO Patent Application WO/2012/111448
Kind Code:
A1
Abstract:
The present invention provides a casting mold used when manufacturing Cu-Ga alloy slabs by a melting and casting method. A casting mold (100) includes a casting body (1) and a sloped member (2). The sloped member (2) has a sloped surface (21), wherein the more the sloped surface (21) extends inwards from an opening (11) of the casting body (1), the more said sloped surface (21) approaches the bottom surface (12) of the casting body (1).
