ABSTRACT:
A plug for closing the opening in the bottom of a top pouring ingot mold is comprised of a preformed plug body having top and bottom ends and an outer peripheral surface providing a contour generally corresponding with that of the mold opening to be plugged. The lower portion of the outer peripheral surface is provided with a coating of a thermally curable sealing composition having a heavy paste-like consistency, and the plug body and coating are enclosed in a heat shrinkable plastic film. In use, the plug is pushed into a plug opening in the bottom of an ingot mold which generally is hot from a previous casting operation, the plastic film disintegrates, the sealing material is squeezed so as to spread and fill the space between the mold opening and plug body, and the heat of the mold cures the sealing material to secure the plug in place and seal the peripheral space between the plug body and mold opening.
