Abstract
A sealing structure is disposed between a metal-casting ingot mold bottom portion and a bottom plate to prevent the leakage of molten steel between the mold and plate. A clay rope disposed in a closed configuration corresponding to the bottom of the ingot mold is affixed to the cardboard sheet with an adhesive system. Overlapping portions of the cardboard sheet are grasped to position the clay rope directly under the ingot mold, and the mold is lowered onto the bottom plate. Hot glue (or pressure sensitive adhesive tape and/or white glue) holds the clay rope on the cardboard sheet. The clay rope is offset at a central portion of the sheet to allow folding of the sheet for transport.
Claims11
A method of providing a seal between a hot metal-casting ingot mold of metal and bottom plate, the metal ingot mold having a circumferentially extending bottom portion, and utilizing a cardboard sheet, an elongated flexible sealing element, and an adhesive system, said method comprising the steps of:
- (a) placing the elongated flexible sealing element on the cardboard sheet so that the sealing element assumes substantially a closed configuration on the sheet corresponding to the circumferentially extending bottom portion of the mold;
- (b) affixing the sealing element to the cardboard sheet solely with the adhesive system, steps (a) and (b) being practiced so that at a central portion of the cardboard sheet the sealing element is offset so that it still conforms to the general configuration of the ingot mold circumferentially extending bottom portion, but so that the cardboard sheet may be folded without the sealing element overlapping itself;
- (c) folding the cardboard sheet at the central portion thereof;
- (d) transporting the cardboard sheet in folded configuration to the ingot mold site;
- (e) unfolding the cardboard sheet;
- (f) placing the cardboard with affixed sealing element on the bottom plate with the sealing element in alignment with the ingot mold circumferentially extending bottom portion;
- and
- (g) lowering the ingot mold onto the bottom plate.
A method of making a sealing structure adapted to be disposed between a hot metal-casting ingot mold of metal and bottom plate, the metal ingot mold having a circumferentially extending bottom portion, and utilizing a cardboard sheet, an elongated flexible sealing element, and an adhesive system, the method comprising the steps of:
- (a) placing the elongated flexible sealing element on the cardboard sheet so that the sealing element assumes substantially a closed configuration on a sheet corresponding to the circumferentially extending bottom portion of the mold;
- (b) affixing the sealing element to the cardboard sheet solely with the adhesive system, so that at a central portion of the cardboard sheet the sealing element is offset so that it still conforms to the general configuration of the ingot mold circumferentially extending bottom portion, but so that the cardboard sheet may be folded without the sealing element overlapping itself;
- (c) folding the cardboard sheet at the central portion thereof, and
- (d) transporting the cardboard sheet in folded configuration.
A sealing structure adapted to be disposed between a metal-casting ingot mold and a bottom plate, and comprising:
- a clay rope having a predetermined diameter;
- a cardboard sheet;
- and
- means for affixing the sealing element to the cardboard sheet in a closed pattern configuration corresponding to the configuration of an ingot mold bottom portion and so that said clay rope is offset at a central portion of said cardboard sheet a distance greater than the diameter of said clay rope, said affixing means consisting of an adhesive system.
