Abstract

This invention relates to an improved ingot mold. The only alteration in design involves the outside surface of the ingot mold. The invention involves recesses cast or cut into the outside surface of ingot molds for the specific purpose of accommodating steel reinforcement bands. These recesses allow air spaces to exist between the mold surface and the steel reinforcement bands for the purpose of reducing thermal conduction and to bridge any irregularities in the iron mold surface. They can further allow the band to be applied in such a way that the band does not extend beyond the furthest outside surface of the ingot mold exterior wall. The benefit of this is that the steel band is protected from any abuse that may occur as a result of handling the mold. The further benefit is achieved of protecting the band from molten steel that may splash from the top of the mold during teeming (pouring) or transportation. The band is set deeply enough into the mold surface that any molten steel will drip down the outside of the band rather than between the band and the mold wall.

Claims3

Dependent claims

An improved ingot mold, having vertical faces with vertical corner edges there between, and a reinforcing band placed around the mold over the vertical forces and the vertical corner edges;

the improvement which comprises:
each face of said mold having at least one vertical recess defined therein, each recess being at approximately the same latitude and of a height greater than the width of the reinforcing band used to reinforce and repair said mold,
each recess being separated from adjacent recesses by a less recessed portion defined in
each vertical corner edge, said less recessed portion being located therein at approximately the same latitude as the recesses in the faces of said mold, each less recessed portion being of a depth at least as great as the thickness of the reinforcing band, and of a height at least as great as the width of said reinforcing band;
the reinforcing band being placed around the mold over the face recesses and the less recessed portions, contacting the mold only at the less recessed portions, thereby reducing heat conduction to said reinforcing band, said reinforcing band not protruding outward beyond the vertical corner edges of the mold, thereby protecting said band from damage should the corner edges of said mold contact another object.
