Abstract

An exemplary embodiment relates to a fireproof ceramic bottom in the connection region to at least one wall of a vessel for handling high-temperature melts.

First claim

The invention claimed is:

1. Fireproof ceramic base in a connection area to at least one wall ( 52 ) of a vessel ( 50 ) for treatment of a high temperature melt, with the following characteristics:
a) the fireproof ceramic base features at least two layers ( 10 , 20 ), namely
b) a lower layer made of a fireproof ceramic permanent lining ( 10 ) comprising at least one monolithic fireproof mass, and
c) an upper layer made of a fireproof ceramic wear lining ( 20 ), wherein
d) the permanent lining ( 10 ) features a surface ( 10 o ) which is adjacent to the wear lining ( 20 ), which is sloped by at least 2° to 25° compared to the horizontal,
e) this surface ( 10 o ) features a three dimensional design including at least one step ( 13 ), and
f) the wear lining ( 20 ) consists of at least 60 M % of fireproof ceramic solid bricks ( 21 ), wherein at least 60% of the solid bricks of the wear lining ( 20 ) are identical, wherein at least 70 M % of said solid bricks feature a rectangular or polygonal profile in a top view, and wherein at least 75% of the solid bricks ( 21 ) of the wear lining ( 20 ) being laid in a single layer,
g) the permanent lining ( 10 ) and the wear lining ( 20 ) feature at least one inconsistency for integration of at least one common discharge opening ( 30 ) for the high temperature melt.

2. Base according to claim 1 , whose permanent lining ( 10 ) is a premade element which has been made out of at least one monolithic fireproof mass.

3. Base according to claim 1 with at least one separate element ( 14 , 30 ) which is built into the permanent lining ( 10 ) and the wear lining ( 20 ).

4. Base according to claim 1 , wherein the solid bricks ( 21 ) of the wear lining ( 20 ) are at least partially laid as pre-assembled segments consisting of multiple solid bricks.

5. Base according to claim 1 , whose wear lining ( 20 ) consists of at least 80 M % solid bricks ( 21 ), which have their largest extension in a vertical direction.

6. Base according to claim 1 , wherein the solid bricks ( 21 ) of the wear lining ( 20 ) consist of at least one material, wherein the material is Magnesia, Alumina, Magnesia-Carbon, Doloma, or Magnesia-Chromite.

7. Base according to claim 1 , wherein pendentives ( 23 )
between the solid bricks ( 21 )
between the solid bricks ( 21 ) and the at least one wall ( 52 ) of the vessel ( 50 )
between the solid bricks ( 21 ) and the permanent lining ( 10 )
between solid bricks ( 21 ) and a separate element ( 14 , 30 ) in the base are at least partially filled with a fireproof ceramic mass.

8. Base according to claim 3 , wherein pendentives ( 23 )
between the solid bricks ( 21 )
between the solid bricks ( 21 ) and the at least one wall ( 52 ) of the vessel ( 50 )
between the solid bricks ( 21 ) and the permanent lining ( 10 )
between solid bricks ( 21 ) and a separate element ( 14 , 30 ) in the base are at least partially filled with a fireproof ceramic mass.
