Abstract
The utility model provides a graphite crucible for an electroslag furnace. The graphite crucible mainly comprises a flange, a shell, a graphite crucible lining, a slag outlet and bolts. The graphite crucible lining is made of a graphite pocket brick and a side wall arranged on the graphite pocket brick, wherein the graphite pocket brick is formed by a whole graphite block and the side wall is formed by bricklaying of graphite bricks. The front and rear surfaces of each graphite brick are designed as curved surfaces and have the same curvatures. Therefore, the curvature of the crucible's side wall can be freely changed and the graphite bricks can keep a tight grip with each other. Upper and lower layers of the graphite bricks are laid in a staggered pattern. By the adoption of the utility model, processed dies are saved, processing difficulty is reduced, the volume of the material graphite for the crucible is decreased, the cost is minimized, strength, refractoriness and electrical conductivity are guaranteed, and good slagging can be achieved. In addition, it is proved through a test that the improved crucible for a 15 ton electroslag furnace can be used to save 4/5 of the cost and reduce the production cost in comparison with a traditional crucible.
Description
Technical field
The utility model relates to a kind of plumbago crucible, and particularly a kind of electroslag furnace is used plumbago crucible.
Background technology
At present, in large-size electroslag furnace, change slag and adopt the three-phase alternating current power supply mode more,, must build a coverization slag station in addition, promptly one road three-phase supply must be provided in addition in order to change slag because the electroslag furnace body is a single phase poaer supply.This form not only increases the gross investment of engineering, and wastes the existing single phase poaer supply of founding.And adopt founding station slag, and the plumbago crucible lining is one-piece construction in traditional large-size electroslag furnace, and required graphite raw material volume is big, and difficulty of processing is high, and involving great expense makes it not use widely.Therefore, solving founding station slag subject matter is the cost problem of crucible.
The utility model content
The purpose of the utility model is to overcome the problem and shortage of using the existence of conventional graphite crucible in the founding station slag process and provides a kind of investment low, and the little novel electroslag furnace of difficulty of processing is used plumbago crucible.
The utility model electroslag furnace mainly comprises flange, shell, plumbago crucible lining, slag notch, bolt with electroslag furnace with plumbago crucible.It is characterized in that; Plumbago crucible lining by the graphite brick cup with and top sidewall constitute; Plumbago crucible lining sidewall is built by laying bricks or stones by the several layers graphite brick and is formed, and monoblock graphite brick cup is positioned in the circular hole at outer casing bottom center, and the plumbago crucible lining that is combined into one is built in the shell.
Graphite brick front and back opposite face is designed to curved surface and curvature is identical, and with the mutual interlock of layer graphite brick curved surface, the levels graphite brick is staggered builds by laying bricks or stones.
Use the utility model and not only save processing mold, reduce difficulty of processing, and reduced the raw materials used graphite volume of conventional graphite crucible, thereby reduced the cost of plumbago crucible.The utility model is applied in the founding station slag electroslag furnace; Through evidence; 15 tons of electroslag furnaces have guaranteed intensity, refractoriness and electroconductibility with the crucible after improving, and reach good change slag purpose, compare with the whole plumbago crucible electroslag furnace of conventional use; The expense of saving 4/5ths has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the graphite brick vertical view.
1 is that flange, 2 is that body of heater, 3 is that filler, 4 is that graphite brick cup, 5 is that graphite brick, 6 is that bond, 7 is that bolt, 8 is a slag notch among the figure.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain:
As shown in Figure 1: electroslag furnace is mainly by flange 1, body of heater 2, filler 3, graphite brick cup 4, graphite brick 5, bond 6, and bolt 7, slag notch 8 are formed.
Graphite brick cup 4 is positioned in the circular hole of shell 2, and using mineral carbon brick 5 is built crucible lining sidewall by laying bricks or stones, graphite brick 5 is placed on the graphite brick cup 4 begin to build by laying bricks or stones; With 6 bondings of the bond with electroconductibility, with the mutual interlock of layer graphite brick 5 curved surface, fill with bond 6 in the slit between graphite brick 5 and the graphite brick cup 4; Successively build by laying bricks or stones successively; Levels graphite brick 5 usefulness bonds, 6 bondings and staggered building by laying bricks or stones, tamp with filler 3 in the space between crucible lining and the shell 2, guarantees the intensity and the electroconductibility of crucible.
Graphite brick 5 front and back opposite faces are designed to curved surface and curvature is identical, to reach the purpose that can freely change the crucible wall curvature and make interlock consolidation between the graphite brick 5, guarantee that crucible has good refractoriness and electroconductibility.
8 sides of slag notch in the crucible wall upper end, crucible wall upper ends flange 1, fixing through bolt 7, the intensity of assurance crucible.
