Abstract
The invention discloses an electrolytic tank AB beam and a manufacturing method thereof. The AB beam comprises an upper wing plate, a web, and a lower wing plate. The upper wing plate is parallel to the lower wing plate, the web is arranged between the upper wing plate and the lower wing plate and is perpendicular to the upper wing plate and the lower wing plate, and the web is connected to the upper wing plate and the lower wing plate through twin fillet wolt. The cross section of the web is in a shape of trapezoidal waves with arc angles. Compared to the prior art, the AB beam has better mechanical performances such as higher bearing capacity, higher rigidity, better anti-twisting property, and the like. The provided AB beam has an excellent performance on resisting bending/twisting destruction and local bearing destruction which usually happens to electrolytic tank AB beams. The relationship between the cross section mechanical performances and steel using amount is greatly optimized by the provided cross section combination, and moreover the used steel materials are largely reduced compared to that of conventional AB beams.
Description
Technical field
the present invention relates to a kind of AB beam for electrolytic tank and making method, belong to the manufacture technology field that electrolyzer hangs girder steel.
Background technology
aB beam is the key member of Aluminum Electrolysis Production, and modern large-scale aluminum electrolytic cell many employings cradle-type pot shell, its underpart structure is mainly made up of pot shell and a series of bassinet stand.The long side load of pot shell mainly relies on bassinet stand to bear, and passes on basis eventually through AB beam.AB beam as one of force path generally adopts i shaped cross section, and is placed directly on concrete buttress.AB beam is the primary support member of electrolytic bath cradle bracket, bassinet stand to the very large concentrated force of AB beam effect, and due to temperature expansion to AB beam upper flange produce greatly level to frictional force.The existence of these two kinds of loads has had higher requirement to the partial pressing of AB beam, overall stability.Traditional i shaped cross section beam increases stiffener and can address this problem to a certain extent in web both sides, load place that bassinet stand transmits, but DeGrain and steel using amount is large, and construction is complicated.
Summary of the invention
the object of the invention is to, a kind of AB beam for electrolytic tank and making method are provided, to improve the shearing resistance of AB beam for electrolytic tank, bending resistance, antitorque and local load performance.。
technical scheme of the present invention:
a kind of AB beam for electrolytic tank, comprises the upper flange and lower wing plate that be arranged in parallel, is provided with web between upper flange and lower wing plate; The cross-sectional shape of web is by the trapezoidal end to end waviness formed of one group of symmetry.
in aforementioned AB beam for electrolytic tank, described trapezoidal oblique line inclination alpha is 30-80 °.
in aforementioned AB beam for electrolytic tank, described trapezoidal bending part is fillet.
in aforementioned AB beam for electrolytic tank, described web top and bottom respectively with upper flange and lower wing plate vertical welding.
the making method of aforementioned AB beam for electrolytic tank, the trapezoidal wave shape wave that steel band to be bent into arc chord angle by numerical control bender by the method along its length makes web; Cut out two pieces of rectangles as upper flange and lower wing plate with steel plate again, lower wing plate welds with its base sides, and upper flange welds with web top margin.
in preceding method, described web adopts automatic fillet welding carriage to weld with welding of upper lower wing plate.
compared with prior art, the present invention has the excellent stress performance such as high-bearing capacity, high rigidity, high anti-twisting property.Especially with local bearing failure, there is positive effect to preventing the recurrent bending of aluminium cell AB beam from destroying.Section combination of the present invention optimizes the relation of section mechanical property and steel using amount to a greater extent, than traditional AB beam form more saving steel.
