ABSTRACT:
The hot top utilizes an integral angle iron structure connected to the hot top for avoiding seal leaks of molten metal through the space between the bottom portion of the hot top and the top of the mold wall. By providing the angle iron structure with a plurality of holes which allow the cooling ingot metal to tear out portions of the structure as the ingot contracts, such structure also allows the cooling ingot to move downwardly in the mold and to separate from the structure, thereby preventing hanger cracks from occurring.
