ABSTRACT:
A channel bag and a one piece spout sock and channel bag assembly for casting metal ingots. The channel bag includes diverter strips along upper portions of the sides and a diverter panel in the bottom of the channel bag positioned to be beneath a downspout during a casting process. The diverter strips and panel deflect poured molten metal and reduce turbulence during the casting process thereby reducing the formation of oxides and other impurities. In the one piece spout sock and channel bag assembly, the spout sock is utilized to receive and properly align a downspout. An ingot casting procedure utilizing the apparatus of the present invention reduces or eliminates the use of skimmers and ingot scalping.
