Several pieces of pure aluminium sheet ingots were trially produced from identically charged molten metal by semi continuous casting process. Under the different casting conditions, particularly the height of molten metal in the mold, and casting speed, the comparative examination was made on the components and structure of thus produced sheet ingots.
The findings were as follows:
The height of molten metal in the mold is a very important factor for getting good ingot. By lowering the height of molten metal, the segregation of ingot surface can be reduced and the structure gets uniform. The effect of casting speed is much less than that of the height of metal in the mold.
