Description
Technical field
The utility model belongs to charcoal piece technical field, relates in particular to a kind of aluminum electrolyzing cell used special-shaped lateral part charcoal piece.
Background technology
In recent years, China's non-ferrous metals industry is fast-developing, and wherein electrolytic aluminum industry occupies very big proportion, and China's aluminium output occupies first place in the world for years.Aluminium cell is the main equipment of electrolysis of aluminum.Electrolysis of aluminum is the fused salt electrolysis process with severe corrosive, and charcoal piece erosion resistance is high, electroconductibility and thermal conductivity are good, and therefore building electrolyzer by laying bricks or stones, to adopt the charcoal piece be inner lining material always.Bottom of electrolytic tank is used to be bottom charcoal piece, and as the negative electrode conduction current, therefore claims cathode carbon pieces again; The electrolyzer sidepiece is built by laying bricks or stones with side wall carbon block.Existing lateral mass is that rectangular parallelepiped is plate, pricks solid between lateral mass and sole piece with ramming paste.But lateral mass that rectangular parallelepiped is plate and sole piece are wasted time and energy with stick with paste pricking to build by laying bricks or stones admittedly, and solidness is general, and erosion resistance and abrasion resistance are relatively low, and these factors all can reduce the work-ing life of electrolyzer.Bad like abrasion resistance, can in aluminium liquid, mix impurity, cause the primary aluminum quality to descend.On thermal equilibrium, the steady running of electrolyzer should be incubated sidepiece heat radiation again by furnace bottom.Therefore, press for the SF that structure is advanced rationally, intensity is high, side wall carbon block that heat conductivity is good increases electrolyzer work-ing life and electrolysis production, improve aluminium manufacturer's primary aluminum quality and output.
The utility model content
The technical problem that the utility model will solve just provide a kind of build by laying bricks or stones time saving and energy saving, can reduce cold smash stick with paste consumption, prevent aluminium liquid seepage, anti-ly wash away, corrosion resistant aluminum electrolyzing cell used special-shaped lateral part charcoal piece.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise the side wall carbon block body; The said side wall carbon block upper part of body outside is provided with terraced groove; Ladder groove place is provided with the intensive aspect that the silicon nitride combined silicon carbide piece constitutes, and the bottom transverse of side wall carbon block body is provided with the seat support that the plane is a ramped shaped.
Its additional technical feature is: the medial surface of said seat support is provided with seepage-proof trough; The xsect of said seepage-proof trough is waviness or profile of tooth; Described intensive aspect is rectangular-shaped or the halfpace shape.
A kind of aluminum electrolyzing cell used special-shaped lateral part charcoal piece that the utility model provided compared with prior art is provided with terraced groove in the plate side wall carbon block upper part of body of the common rectangular parallelepiped outside, and terraced groove place is provided with the intensive aspect that the silicon nitride combined silicon carbide piece constitutes.Because of the silicon nitride combined silicon carbide bulk strength is high far beyond the charcoal piece, improved intensity, the especially compressive strength of lateral mass.The bottom transverse of side wall carbon block body is provided with the seat support that the plane is a ramped shaped; Aluminum electrolyzing cell used special-shaped lateral part charcoal piece is integral structure up and down; Pre-baked carbon block intensity is high, build by laying bricks or stones time saving and energy saving, electrolyzer is sturdy and durable, fast, even, regular, the anti-thermal shock good stability of stove group's formation speed; The pre-baked carbon block heat conductivity is good, and it is all right to dispel the heat during the electrolyzer operation, helps electrolyzer and under the processing condition of stability and high efficiency, moves production; The charcoal piece of a part in the former ramming paste after by roasting replaces, and the pre-baked carbon block resistance to corrosion is strong, anti-to be washed away, thermal conductivity is good; The consumption of ramming paste reduces greatly, the release of bitumen flue gas has improved the working conditions when electrolyzer is built by laying bricks or stones when having reduced roasting before building groove and starting with the new groove of electrolyzer, has reduced energy consumption and environmental pollution that the new groove of electrolyzer starts preceding roasting.The medial surface of this special-shaped lateral part charcoal piece seat support is provided with seepage-proof trough, can prevent the negative electrode sole piece of aluminium liquid seepage damage electrolyzer bottom.By the aluminium cell that this special-shaped lateral part charcoal piece is built by laying bricks or stones, the primary aluminum steady quality of production has improved the work-ing life of electrolyzer and the SF of electrolysis production.According to demands of different, the xsect of seepage-proof trough is waviness or profile of tooth, and intensive aspect is rectangular-shaped or the halfpace shape.

Embodiment
Explain further details below in conjunction with the structure and the use principle of accompanying drawing to the aluminum electrolyzing cell used special-shaped lateral part charcoal of the utility model piece.
Like Fig. 1, shown in 2; The aluminum electrolyzing cell used special-shaped lateral part charcoal of the utility model piece comprises side wall carbon block body 1; The upper outside of side wall carbon block body 1 is provided with terraced groove 2; Ladder groove 2 places are provided with the intensive aspect 3 that the silicon nitride combined silicon carbide piece constitutes, and the bottom transverse of side wall carbon block body 1 is provided with the seat support 4 that the plane is a ramped shaped, and the medial surface of seat support 4 is provided with seepage-proof trough 5.The xsect of seepage-proof trough 5 can be profile of tooth as shown in Figure 3, also can be shapes such as waviness.Intensive aspect 3 can be as shown in Figure 1 rectangular-shaped, also can be halfpace shape as shown in Figure 2.
When a kind of aluminum electrolyzing cell used special-shaped lateral part charcoal piece that the utility model provided uses; As shown in Figure 4; Build aluminum electrolyzing cell used special-shaped lateral part charcoal block body 1 by laying bricks or stones electrolyzer 6 bottom surfaces and side intersection, 1 of negative electrode sole piece 7 and special-shaped lateral part charcoal block body are pricked solid with the cold paste 8 of smashing.This aluminum electrolyzing cell used special-shaped lateral part charcoal piece is an integral structure, and pre-baked carbon block intensity is high, build by laying bricks or stones time saving and energy saving, electrolyzer is sturdy and durable, fast, even, regular, the anti-thermal shock good stability of stove group's formation speed.The medial surface of seat support 4 is provided with seepage-proof trough 5, can prevent the negative electrode sole piece of aluminium liquid seepage damage electrolyzer 6 bottoms.According to demands of different, the xsect of seepage-proof trough 5 is waviness or profile of tooth, and intensive aspect 3 is rectangular-shaped or the halfpace shape.
