The bimetal aluminum suction pipe disclosed by the utility model combines the low price of the common aluminum suction pipe with the excellent property of the heat-resistant and corrosion-resistant material, thereby effectively prolonging the service life of the aluminum suction pipe; and the bimetal aluminum suction pipe disclosed by the utility model is simple in manufacturing process and low in material cost, thereby achieving very high cost performance.
Description
Technical field
The utility model relates to the suction aluminum pipe that uses in field of aluminum electrolysis, relates in particular to a kind of bimetal and inhales aluminum pipe.
Background technology
In recent years, China's aluminium industrial development is rapid, and electrolytic aluminum output ranks first place, the world, and the aluminium production technology reaches in many aspects or near advanced international standard, especially large-sized prebaked electrolyzer is widely applied, and the smelting level of aluminium has had large increase.Two-maing ladle is visual plant in the Aluminum Electrolysis Production process, and it is mainly bearing from electrolyzer the task with the sucking-off of high temperature aluminum liquid, transhipment.All kinds (comprising uncovered two-maing ladle and vacuum ladle) the indispensable important feature of two-maing ladle and inhale aluminum pipe.During work, inhale in the aluminium liquid of aluminum pipe insertion aluminum electrolytic tank, utilize siphon principle, during aluminium water is inhaled into and two-mans ladle.And the temperature of aluminium water is up to 1300 ~ 1400 ℃, and has the ionogen fluorochemical.What this just required to inhale aluminum pipe wants high temperature resistant 1400 ℃ with material, and anti-oxidant under 1400 ℃ of high temperature, and cold and hot fatigue property all will be got well, and can bear 1400 ℃ of high temperature aluminum liquid and electrolytically wash away and corrode.
Inhale the aluminum pipe bottom and be immersed in high temperature aluminum liquid, Working environment is extremely abominable, and the problems such as oxidation, high temperature corrosion, electrolyte corrosion of inhaling aluminum pipe easily cause inefficacy such as the pitting corrosion of inhaling aluminum pipe, perforation, corrosion directly to affect the work-ing life of suction aluminum pipe.
A lot of electrolysis of aluminum workers and researcher are studied and improve the behavior of lengthening the life of inhaling aluminum pipe, but published achievement and few.Existing published patent " graphite aluminum absorption sleeve " (200920319079.9), formed by graphite sleeve, areole and suction aluminum pipe, mainly the perturbed problem that solves the aluminium liquid layer, to inhale aluminum pipe itself to be subjected to the problem effect such as aluminium corrosion be not obvious especially.Have recently producer to utilize graphite as material, made the anti-oxidant suction aluminum pipe of whole graphite, although this graphite is inhaled the oxidation-resistance of aluminum pipe, solidity to corrosion and thermal shock resistance are good, and cost is too high, promotes extremely difficult.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of high temperature resistant, corrosion-resistant and long lifetime that cost performance is high to inhale aluminum pipe.
Concrete technical scheme of the present utility model is as follows:
A kind of bimetal is inhaled aluminum pipe, is made of the two portions up and down that are connected as a single entity, and its top is that common suction aluminum pipe (1), bottom are heat-resisting, corrosion resistant material pipe (2).
As preference:
The material of described common suction aluminum pipe is carbon steel or low alloy steel.
Described heat-resisting, corrosion resistant material is Steel Bond Hard Alloy or high quality steel.
Described common suction aluminum pipe (1) be connected, corrosion resistant material pipe (2) adopts extrusion molding, welding or founding Transition Technology connect moulding.
Described common suction aluminum pipe (1) be connected, corrosion resistant material pipe (2) adopts bump type to connect.
The length of described heat-resisting, corrosion resistant material pipe is greater than the height of electrolyzer.
The working method that above-mentioned bimetal is inhaled aluminum pipe is:
1, utilize prior art, produce common suction aluminum pipe, inhale the upper part of aluminum pipe as bimetal.
2, according to the specification of aluminium cell, produce heat-resisting, corrosion resistant material pipe with heat-resisting, corrosion resistant material, inhale the lower part of aluminum pipe as bimetal.
3, with common suction aluminum pipe be connected, the corrosion resistant material pipe adopts extrusion molding, welding or founding Transition Technology connect moulding.
Two kinds of pipes of step 1 and 2 can be carried out the processing of convex-concave platform according to schema respectively for increasing strength of joint in aforesaid method, two kinds of pipes of step 1 and 2 are carried out the processing of convex-concave platform according to schema respectively, the number of convex-concave platform can be according to the practical situation adjustment.
The utility model combines the premium properties cheap and corrosion-resistant, heat-stable material of carbon steel, adopt extrusion molding, welding or founding Transition Technology to connect, can not only effectively extend the work-ing life of inhaling aluminum pipe, simultaneously, its manufacture craft is simple, the cost of material is low, so this novel dual metal suction aluminum pipe has very high cost performance.
Description of drawings
Figure 1 shows that embodiment 1 indication bimetal inhale the axial section of aluminum pipe.
In figure, (1) is carbon steel tubing, (2) Steel Bond Hard Alloy pipe.
Figure 2 shows that embodiment 2 indications bimetal inhale the axial section of aluminum pipe.
In figure, (1) is low alloy steel, (2) high alloy steel pipe.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Be depicted as the embodiment of a kind of composite bimetal pipe of the present utility model as Fig. 1, described composite bimetal pipe by carbon steel tubing and Steel Bond Hard Alloy pipe by the founding Transition Technology or be welded to connect moulding.
The present embodiment combines the premium properties such as corrosion-resistant, heat-resisting of the cheap and Steel Bond Hard Alloy of carbon steel, can effectively extend and inhale aluminum pipe work-ing life, simultaneously, its manufacture craft is simple, the cost of material is low, so this novel dual metal suction aluminum pipe has very high cost performance.
Low alloy steel (1) and (2) two kinds of pipes of high alloy steel pipe are carried out the processing of convex-concave platform according to schema respectively, adopt extrusion molding that low alloy steel (1) is connected 2 with the high alloy steel pipe) connect moulding.
As shown in Figure 2.
