Abstract
The utility model discloses a repaired structure for a working lining at the middle part of a vertical vacuum refining furnace, and belongs to the technical field of metallurgical furnaces. The repaired structure adopts the scheme that magnesite-chrome slurry (6) is filled on the back of a first ring skew block (7) which is wholly replaced; three to five circles of flat-laid magnesite-chrome bricks (2) for permanent layer are arranged on the surface of the skew block (7) upwards in a position close to an erosion surface (4); the gap between the magnesite-chrome bricks (2) and the erosion surface (4) is filled with the magnesite-chrome slurry (6); and the gap between the top layer of the magnesite-chrome bricks (2) and working bricks (5) are filled with dry magnesite-chrome slurry (1). The utility model has the advantages of reasonable design, simple structure and easy implementation. In addition, the waste of refractory material is avoided, the manufacturing cost is saved, the normal work requirements are met and the service life of the furnace is prolonged.
Description
Technical field
The utility model belongs to the metallurgical furnace technical field, is specifically related to a kind of structure that vertical type vacuum refining furnace middle part working lining is repaired.
Background technology
In the prior art, when the middle part working lining of vertical type vacuum refining furnace uses the about 1600 stove left and right sides, be carried out in accordance with regulations the middle part and repair entirely, promptly remove all middle part permanent layer and working lining, build reduction then on request by laying bricks or stones.Removing heavily the shortcoming of building like this is: when the middle part working lining uses the about 1600 stove left and right sides, mainly be that following 1-6 ring corrodes more serious, though 1-6 ring operational layer brick is residual thick not enough below this, can not work on, but the residual thick instructions for use of still satisfying of the 6 above operational layer bricks of ring can continue to use.Complete removal is heavily built, and has caused the significant wastage of refractory material, has increased the cost of producing of anti-the material.
The utility model content
Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of vertical type vacuum refining furnace middle part working lining preparing structure, this preparing structure can satisfy the operate as normal of vacuum refining furnace, improve the service life of vacuum refining furnace, thereby saved production cost, stopped the waste of refractory material.
The technical solution of the utility model vertical type vacuum refining furnace middle part working lining preparing structure is: fill the magnesium chrome mud at the first ring skew block back side that all changes, on the close position of erosion surface on the skew block table top, the flat permanent layer magnesite-chrome brick of building of 3-5 ring upwards is set, fill the magnesium chrome mud in the space between magnesite-chrome brick and erosion surface, fill dried magnesium chrome mud in the space between last layer magnesite-chrome brick and working brick.
The utility model is reasonable in design, and is simple in structure, implements easily, and production cost has been saved in the waste of having stopped refractory material, and can satisfy normal work requirements, improves the service life of stove.
Description of drawings
Accompanying drawing acceptance of the bid keep the score state as follows: the dried magnesium chrome mud of 1-; The 2-magnesite-chrome brick; 3-permanent layer brick; The 4-erosion surface; The 5-working brick; 6-magnesium chrome mud; The 7-skew block.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.Be the middle part working lining preparing structure of vertical type vacuum refining furnace as shown in drawings, in diagram, omitted substructure.In the prior art,, to carry out the middle part in accordance with regulations and repair entirely, promptly remove all middle part permanent layer and working lining, build reduction then on request by laying bricks or stones when vacuum refining furnace work during to 1600 stoves.Observation and research according to the applicant, recognize that actual conditions are, most of furnace lining of this moment still can work on, the 1-6 ring corrodes more serious just, therefore preparing structure of the present utility model is provided, undermost skew block 7 is all changed, (this point is the same with prior art) built and filled and led up in the back side of skew block 7 by laying bricks or stones with magnesium chrome mud 6, the upwards flat 3-5 of block layer permanent layer magnesite-chrome brick 2 on the table top of skew block 7, fill magnesium chrome mud 6 in the space between magnesite-chrome brick 2 and erosion surface 4, between the superiors' magnesite-chrome brick 2 and working brick 5, fill dried magnesium chrome mud 1.After vacuum refining furnace middle part working lining adopts preparing structure of the present utility model, look middle part working lining erosion condition and can carry out 1-2 such maintenance, can make the middle part working lining re-use the 300-500 stove, make the middle part repair the life-span entirely and bring up to about the 1900-2100 stove, save anti-material expense greatly by 1600 stoves.
Claims (1)
1, working lining preparing structure in the middle part of a kind of vertical type vacuum refining furnace, it is characterized in that: fill magnesium chrome mud layer (6) at first ring skew block (7) back side that all changes, on the close position of erosion surface (4) on skew block (7) table top, the flat permanent layer of the building magnesite-chrome brick (2) of 3-5 ring upwards is set, fill magnesium chrome mud layer (6) in the space between magnesite-chrome brick (2) and erosion surface (4), filling dried magnesium chrome mud layer (1) in the space between last layer magnesite-chrome brick (2) and working brick (5).
