Description
Technical field
The present invention relates to a kind of special form brick, more particularly to a kind of flue wall special form brick and building method, in the flue wall of aluminium anode production field open-type anode roasting furnace.
Background technology
In aluminium anode production process, green anode briquet will make the main physical and chemical index such as its ratio resistance, real density, mechanical strength reach requirement of the aluminum electrolysis technology to conductive anode by high-temperature roasting.This high-temperature calcination process is realized by anode-baking furnace, during anode-baking, with the rising of sintering temperature, in certain temperature range, substantial amounts of high heating value fugitive constituent effusion is had in anode block, these high heating value fugitive constituents are also one of main energetic of generation high temperature in anode-baking.
Existing anode-baking furnace, reserves hollow vertical brickwork joint when substantially being built by laying bricks or stones by flue wall, that is, found seam and do not beat the passage that mud enters quirk burning as fugitive constituent.In recent years, substantial amounts of research work has been made in terms of for how reasonably to set these passages and building method, the combustion utilization efficiency of high heating value fugitive constituent is greatly improved, but still there are following several respects：1st, the fugitive constituent passage of seam is found using adjacent bricks because the quantity by brick is limited, the requirement of fugitive constituent escaped quantity can not be met in some cases；2nd, the fugitive constituent passage for founding seam using adjacent bricks is affected by human factors in building process causes channel size error larger, and the loss of smooth or negative pressure is not excessive into the passage in quirk to cause fugitive constituent；3rd, fugitive constituent is not smooth into the passage of quirk, causes the fugitive constituent in hopper to escape boiler face, is degrading the operating environment of calcination department；4th, this vertical brickwork joint is not struck sparks the flue wall masonry structure of mud, causes flue wall bulk strength to decline, and reduces the service life of flue wall；5th, the structure that closed channel is set inside brick causes the anti-folding of monolithic brick and the compression strength substantially to reduce, and influences the bulk strength of flue wall.6th, the structure that closed channel is set inside brick increased the manufacture difficulty of brick, reduce product qualified rate, it is impossible to realize continuous batch production.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of flue wall special form brick and building method, purpose is that solution fugitive constituent channel size error is big, limited amount, fugitive constituent effusion boiler face pollution environment, fire tunnel wall structure intensity difference influence quirk service life, the pressure-proof and snap-resistent intensity difference of the quirk brick of inner passage, manufacture difficulty are big, qualification rate is low, cannot mass production problem.
It is including the brick body up to a kind of above-mentioned purpose flue wall special shaped brick of the present invention, fugitive constituent channel groove is provided with the top and/or bottom of brick body, the bottom land of fugitive constituent channel groove is fugitive constituent passage, and low temperature filler is provided with fugitive constituent passage.
The thickness of fugitive constituent channel groove insertion brick body.
The upper surface of brick body is provided with boss, and the lower surface of brick body is provided with groove.
The lower surface of brick body is provided with boss, and the upper surface of brick body is provided with groove.
It is the length of boss and groove insertion brick body.
The weight of brick body is 2~20 ㎏；The height of brick body is 50~200 ㎜；The length of brick body is 100~500 ㎜；The thickness of brick body is 70~150 ㎜.
Low temperature filler is made of paper, fibrous or wooden material.
Top or bottom fugitive constituent channel groove are 2-8.
The cross sectional shape of fugitive constituent channel groove is rectangle, trapezoidal or polygon；The ㎜ of height 15~100 of fugitive constituent channel groove, width be 2~10 ㎜, adjacency channel apart from size range be 10~200 ㎜.
The cross sectional shape of boss is semicircle, rectangle, trapezoidal or triangle, and when boss is for semicircle, radius is 3~100 ㎜.
The cross sectional shape of groove is semicircle, rectangle, trapezoidal or triangle, and when groove is for semicircle, radius is 3~100 ㎜.
A kind of building method of flue wall special form brick, it is characterized in that first filling low temperature filler in the fugitive constituent channel groove of brick body, then built by laying bricks or stones, it is engaged with the groove of adjacent brick body when the boss of brick body is built by laying bricks or stones, with the bosses snap of adjacent brick body when the groove of brick body is built by laying bricks or stones, vertical between brick body all makes mud in being sewn on building process, and fugitive constituent channel groove is closed with chamotte.
Advantages of the present invention effect：The fugitive constituent passage being located in brick body is conducive to fugitive constituent in hopper smoothly to enter participation burning in quirk.Because fugitive constituent passage is located in brick body, influence of the temperature change to fugitive constituent channel cross-section width can be prevented effectively from, it is ensured that fugitive constituent passage stablizes indeformable.Be conducive to making full use of for fugitive constituent, reducing energy consumption improves the energy-saving effect of anode-baking furnace.Can obviously reduce pollution of the pernicious gas caused because fugitive constituent can not enter quirk burning to environment.Because all brickwork joints of quirk walling make mortar, the bulk strength of flue wall will be increased substantially after high temperature sintering, extend the service life of roaster.The channel design is simple, it is easy to be manufactured, and is capable of achieving the continuous batch production of special form brick.The passage does not influence the integrated performance indexs such as the compressive resistance and rupture strength of brick body.Solve anode-baking quirk due to stand seam it is hollow cause flue wall bulk strength poor, vertical and lateral deformation is serious, service life is short and production process in produced fugitive constituent under suction function into quirk passage not smooth, part fugitive constituent escape boiler face through inserts coating and the problems such as pollute the fugitive constituent in workshop condition, quirk and import skewness.
