Abstract
The object of the invention is a metallurgical furnace (1), the wall of which comprises an external steel structure (5) and a refractory lining (3) inside the steel structure, the lining (3) consisting of at least one course of bricks (4) in the direction of thickness of the wall of the furnace (1), and that essentially horizontal, ledge-like cooling elements (6) are arranged in the brick lining (3) of the wall of the furnace (1 ), extending to a length (L) from the outer surface (20) of the brick lining (3) of the furnace (1) towards its inner surface (9), the length (L) in the area of the molten material (2) of the furnace (1 ) and its vicinity typically being from 50 to 100% of the thickness (D) of the brick lining (3) and, elsewhere, typically from 20 to 100% of the thickness (D) of the brick lining (3), the cooling elements (6) being attached to the external steel structure (5) of the furnace (1 ) by fastening members (13).
Claims (15)
1. A metallurgical furnace (1) comprising a wall that has an external steel structure (5) and a refractory brick lining (3) inside the steel structure, the lining (3) consisting of at least one course of bricks (4) in the direction of thickness of the furnace (1), characterized in that essentially horizontal ledge-like cooling elements (6) are arranged in the brick lining (3) of the wall of the furnace (1), extending to a length (L) from the outer surface (20) of the brick lining (3) of the furnace (1) towards its inner surface (9); the length (L) in the area of the molten material (2) of the furnace (1) and its vicinity typically being from 50 to 100% of the thickness (D) of the brick lining (3) and, elsewhere, typically, from 20 to 100% of the thickness (D) of the brick lining (3); and the cooling elements (6) being attached to the external steel structure (5) of the furnace (1) by means of fastening members (13).
2. A furnace (1) according to Claim 1, characterized in that the cooling ele-ments (6) extend to a length (L) from the outer surface (20) of the brick lining (3) of the furnace (1) towards its inner surface (9); the length (L) in the area of the molten material (2) of the furnace (1) or its vicinity preferably being from 55 to 100% and, elsewhere, from 25 to 100% of the thickness (D) of the brick lin-ing (3), and most preferably, in the area of the molten material (2) or its vicinity from 60 to 100% and, elsewhere, from 30 to 100% of the thickness (D) of the brick lining (3).
3. A furnace (1) according to Claim 1 or 2, characterized in that the height (H) of the cooling elements (6) in the elevation of the furnace (1) is typically from 40 to 120mm, preferably from 50 to 110mm and most preferably from 60 to 100mm.
4. A furnace (1) according to any of the preceding Claims, characterized in that the distance (E) between the cooling elements in the elevation of the fur-nace (1) in the area of the molten material (2) is typically about 75 to 305mm and preferably about 150 to 230mm.
5. A furnace (1) according to any of the preceding Claims, characterized in that the distance (E) between the cooling elements (6) in the elevation of the furnace (1) in areas other than that of the molten material (2) is about 230 to 610mm and preferably about 305 to 460mm.
6. A furnace (1) according to any of the preceding Claims 1 to 5, charac-terized in that, in the cooling elements (6), there are channels (18) provided for the circulation of cooling liquid and members (19) for feeding and discharging the cooling liquid.
7. A furnace (1) according to Claim 6, characterized in that the channels (18) of the cooling elements (6) are located on the level of the outer surface (20) of the brick lining (3) of the furnace (1) or outside the same.
8. A furnace (1) according to Claim 6, characterized in that the channels (18) of the cooling elements (6) are located inside the brick lining (3) of the furnace (1) and they extend to the midpoint of the brick lining (3) at the maximum.
9. A furnace (1) according to any of the preceding Claims 1 to 8, characterized in that the cooling elements (6) form an essentially continuous ring around the furnace (1) in the area of the molten material (2) and its vicinity.
10. A furnace (1) according to any of the preceding Claims 1 to 8, character-ized in that the cooling elements (6) form an essentially continuous ring or a discontinuous ring around the furnace (1) in areas other than that of the molten material (2) or its vicinity.
11. A furnace (1) according to any of the preceding Claims 1 to 10, character-ized in that the cooling elements (6) are replaceable.
12 12. A furnace (1) according to Claim 11, characterized in that the steel struc-ture (5) of the wall has an essentially horizontal projection (16), which is di-rected towards the inside of the furnace (1), provided above the cooling ele-ment (6), supporting the brick lining (3) during the replacement of the cooling element (6), and that, in the brick (4) above the projection (16), there is a corre-sponding recess (17).
13. A furnace (1) according to Claim 12, characterized in that the inwards-directed projection (16) of the steel structure (5) of the wall is a continuous cir-cular structure or a discontinuous circular structure.
14. A furnace (1) according to any of the preceding Claims 1 to 13, character-ized in that the essentially horizontal projections (14, 15) of the steel structure (5) of the furnace (1), which are directed outwards, form a continuous or a dis-continuous ring around the furnace (1).
15. A furnace (1) according to any of the preceding Claims 1 to 14, character-ized in that the cooling elements (6) are made of copper or some other material that has a good thermal conductivity.
