A vessel for containing high temperature molten metal, said vessel having (a) a supporting shell with side walls and a sloping bottom to form an interior for containing said molten metal, said interior of said vessel including a lining of refractory bricks, and (b) an interconnected refractory leveling assembly comprising a first plurality of high temperature refractory precast modules assembled into a first partial ring and a second plurality of high temperature refractory precast modules assembled into a second partial ring, all of said precast modules having dimensions of height, width and thickness, and wherein each precast module of each partial ring having a sloping height and a median dimension of height different from each adjacent precast module in said each partial ring.
- 8. A vessel according to claim 7 in which said interconnected refractory leveling assembly is located adjacent said bottom of said vessel.
- 9. A vessel according to claim 7 in which adjoining precast modules of each partial ring have an identical median dimension of length.
- 10. A vessel according to claim 7 in which all of said precast modules of said partial rings are essentially identical in width and length.
- 11. A vessel according to claim 7 in which each partial ring is a semicircle.
- 12. A vessel according to claim 7 wherein said vessel is essentially circular.
- 13. A vessel according to claim 7 in which said first partial ring and said second partial ring are mirror images of each other.
- 14. A vessel according to claim 7 wherein said vessel is annular.
- 15. A vessel according to claim 7 in which said first partial ring is a first semicircle and said second partial ring is a second semicircle, in which said semicircles each have a first end and a second end, and in which said first end of said first semicircle is in communication with said first end of said second semicircle and said second end of said first semicircle is in communication with said second end of said second semicircle to form one complete circle.
- 16. A vessel for containing high temperature molten metal, said vessel having (a) a supporting shell with side walls and a sloping bottom to form an interior for containing said molten metal, said interior of said vessel including a lining of refractory bricks, and (b) an interconnected refractory leveling assembly comprising a first plurality of high temperature refractory precast modules assembled into a first partial ring and a second plurality of high temperature refractory precast modules assembled into a second partial ring, all of said precast modules having dimensions of height, width and thickness, each precast module of each partial ring having a sloping height and a median dimension of height different from each adjacent precast module in said each partial ring, in which said first partial ring is a first semicircle and said second partial ring is a second semicircle, in which said semicircles each have a first end and a second end, and in which said first end of said first semicircle is in communication with said first end of said second semicircle and said second end of said first semicircle is in communication with said second end of said second semicircle to form one complete circle, and in which said heights of adjoining ends of said precast modules at adjoining ends of said first and said second semicircles are essentially identical.
- 17. A vessel for containing high temperature molten metal, said vessel having (a) a supporting shell with side walls and a sloping bottom to form an interior for containing said molten metal, said interior of said vessel including a lining of refractory bricks, and (b) an interconnected refractory leveling assembly comprising a first plurality of high temperature refractory precast modules assembled into a first partial ring and a second plurality of high temperature refractory precast modules assembled into a second partial ring, all of said precast modules having dimensions of height, width and thickness, each precast module of each partial ring having a sloping height and a median dimension of height different from each adjacent precast module in said each partial ring, further including at least one additional level of at least one leveling refractory precast module overlying said first partial ring and said second partial ring to further compensate for said sloping bottom of said vessel.
