Abstract
The invention provides a graphite crucible which is mainly composed of a graphite pocket block and a graphite side wall arranged on the graphite pocket block. The graphite pocket block is of an integrated structure. The graphite side wall is built by a plurality of layers of graphite bricks. Front faces and back faces, opposite to each other, of the graphite bricks are designed to be curve and the curvature of the front faces and the curvature of the back faces are identical. An upper layer of the graphite bricks and a lower layer of the graphite bricks are built in an interlaced mode. According to the graphite crucible, the size of raw material graphite is reduced so that processing cost of the graphite crucible is reduced, and good intensity, refractoriness and electrical conductivity are guaranteed.
Description
Technical field
The present invention relates to a kind of graphite crucible, particularly for electroslag furnace slag graphite crucible.
Background technology
At present, in large-size electroslag furnace, change slag and adopt the three-phase alternating-current powered mode more, because the electroslag furnace body is single phase poaer supply, must build in addition a coverization slag station in order to change slag, namely must provide in addition one road three phase mains.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 graphite crucible is overall structure in traditional large-size electroslag furnace, and required graphite raw material volume is large, and difficulty of processing is high, involves great expense so that it can not be used widely.Therefore, solving founding station slag subject matter is the cost problem of crucible.
Summary of the invention
The object of the invention is to overcome the problem and shortage of using the existence of traditional integral graphite crucible in the founding station slag process and provide a kind of investment low, the graphite crucible that difficulty of processing is little.
Graphite crucible of the present invention mainly is comprised of graphite brick cup and top graphite side wall thereof, and the graphite brick cup is overall structure, and graphite side wall is built by laying bricks or stones by some layers of graphite brick and formed.
Graphite brick front and back opposite face is designed to curved surface and curvature is identical, and with the mutual interlock of graphite brick curved surface before and after the layer, the levels graphite brick is staggered builds by laying bricks or stones.
Use the present invention 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 graphite crucible.The present invention is applied in the founding station slag electroslag furnace, through evidence, 15 tons of electroslag furnaces have guaranteed intensity, refractoriness and the electric conductivity of crucible with the crucible after improving, reach good change slag purpose, compare with traditional using integral graphite crucible electroslag furnace, the expense of saving 4/5ths has reduced production cost.
Description of drawings
Fig. 1 is that the present invention uses state diagram.
Fig. 2 is the graphite brick top 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 binding material, 7 is that bolt, 8 is slag notch among the figure.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present invention is described in further detail:
The application of embodiment the present invention in founding station slag electroslag furnace
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, binding material 6, bolt 7, and slag notch 8 forms.
Graphite brick cup 4 is positioned in the circular hole of body of heater 2, using mineral carbon brick 5 is built crucible wall by laying bricks or stones, graphite brick 5 is placed on the graphite brick cup 4 begins to build by laying bricks or stones, bond with the binding material 6 with electric conductivity between graphite brick 5 and the graphite brick cup 4, with the mutual interlock of layer graphite brick 5 curved surface, fill with binding material 6 in the slit, successively build by laying bricks or stones successively, levels graphite brick 5 usefulness binding materials, 6 bondings and staggered building by laying bricks or stones, tamp with filler 3 in space between crucible and the body of heater 2, 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 5.8 sides in the sidewall of crucible upper end of slag notch, sidewall of crucible upper ends flange 1, fixing by bolt 7, intensity, refractoriness and the electric conductivity of assurance crucible.The form of building by laying bricks or stones of the present invention can be widely used in various types of crucibles.
