Abstract
The invention concerns a casting vessel having a basic lining, and usage thereof. For putting in practice the casting vessel employing basic refractories as a lining material and in order to avoid such phenomena as exfoliation or others caused by thermal stress generated in the inside of the lining, a backing between the lining and an outer shell is partially or entirely composed of cushion material having thickness within specific range, thereby to absorb said stress and save a life of the lining, and further temperature within the casting vessel is kept above determined temperature before it holds molten metal, thereby to make more efficient use of the life of the basic lining.
