Description
Technical field
The utility model relates to a kind of electrolytic aluminum ladle aluminum pipe sucking, belongs to electrolytic aluminum field.
Background technology
In recent years, rapidly, electrolytic aluminum output hero occupies first place in the world China's aluminum i ndustry development, and aluminium production technology reaches in many aspects or close to advanced international standard, especially large prebaked cell for aluminum-reduction is widely applied, and the smelting level of aluminium has had large increase.Two-maing ladle is visual plant in Aluminum Electrolysis Production process, and it mainly carries the task of the sucking-off of high temperature aluminum liquid, transhipment from electrolyzer.And to inhale aluminum pipe be that all kinds are two-mand ladle (comprising uncovered two-maing ladle and vacuum ladle) indispensable important feature.During work, inhale aluminum pipe and insert in the aluminium liquid of aluminum electrolytic tank, utilize siphon principle, during aluminium water is inhaled into and two-mans ladle.And the temperatures as high 1300 ~ 1400 DEG C of aluminium water, and have ionogen fluorochemical.What this just required to inhale aluminum pipe wants high temperature resistant 1400 DEG C with material, and anti-oxidant under 1400 DEG C of high temperature, cold-heat fatigue property all will be got well, and can bear 1400 DEG C of high temperature aluminum liquid and electrolytically wash away and corrode.
In order to extend the work-ing life of inhaling aluminum pipe, a lot of electrolysis of aluminum worker and researcher improve the material inhaling aluminum pipe, but all inhale aluminum pipe inwall based on protection.But suction aluminum pipe bottom is immersed in high temperature aluminum liquid, Working environment is extremely severe, and the problem such as oxidation, high temperature corrosion, electrolyte corrosion of inhaling aluminum pipe easily causes the pitting corrosion, perforation, corrosion etc. inhaling aluminum pipe to lose efficacy and directly affects the work-ing life of suction aluminum pipe.
Electrolysis of aluminum worker and researcher are studied and improvement the behavior of lengthening the life of inhaling aluminum pipe, but published achievement is also few.Existing published patent " graphite aluminum absorption sleeve " (200920319079.9), are made up of graphite sleeve, areole and suction aluminum pipe, have used the feature such as high temperature resistant, corrosion-resistant of graphite fibre well.But this patent has just installed the device that a graphite is made additional in suction aluminum pipe bottom, erosion and the problem of oxidation of inhaling aluminum pipe itself are not but resolved, and meanwhile, the fragility of graphite is larger, below suction aluminum pipe, directly adopt the graphite tube without other propping materials, easily cause the situations such as fracture.Have producer to utilize graphite as material recently, made the anti-oxidant suction aluminum pipe of overall graphite, although this graphite inhales the oxidation-resistance of aluminum pipe, solidity to corrosion and good in thermal shock, cost is too high, promotes extremely difficult.Patent " high strength composite sucking aluminum pipe " (200520118707.9); graphite blank is built; use lathe precision work again; also just protection has to a certain degree been carried out to suction aluminum pipe inside; but the strength of joint of its graphite blank and external metallization waits further raising; also long term operation is under the severe environment such as easy oxidized, corrosion to consider to inhale aluminum pipe outside, and meanwhile, its technological operation difficulty is relatively large.And the method that aluminum pipe employing extrusion molding inhaled by bimetal can not ensure the intensity that metal connects, graphite protective sleeve is inhaled aluminum pipe and is then difficult to overcome the frangible characteristic of graphite.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of high temperature resistant, corrosion-resistant and electrolytic aluminum ladle aluminum pipe sucking that cost performance is high.
The technical solution of the utility model is as follows:
A kind of electrolytic aluminum ladle aluminum pipe sucking, being made up of the two portions be up and down connected as a single entity, its top is carbon steel tubing, and bottom is carbide reactor welded tube, and described carbon steel tubing and carbide reactor welded tube adopt bead-welding technology to be connected.
Electrolytic aluminum ladle aluminum pipe sucking of the present utility model, top is common suction aluminum pipe, and employing material is carbon steel.
Described carbide reactor welded tube is formed by D802 welding rod, YD856 welding rod or other type hard alloy overlay welding.
The length of described carbide reactor welded tube is greater than the height of electrolyzer.
The premium properties of cheap and corrosion-resistant, the heat-resisting resurfacing welding material of carbon steel combines by the utility model, bead-welding technology is adopted to connect, effectively can not only extend the work-ing life of inhaling aluminum pipe, simultaneously, its manufacture craft is simple, the cost of material is low, and therefore this built-up welding suction aluminum pipe has very high cost performance.
Accompanying drawing explanation
Figure 1 shows that embodiment 1 indication the structural representation of suction aluminum pipe.
In figure, 1 is carbon steel tubing 2 for carbide reactor welded tube 3 is thin-wall ceramic pipe.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of electrolytic aluminum ladle aluminum pipe sucking, being made up of the two portions be up and down connected as a single entity, its top is carbon steel tubing, and bottom is carbide reactor welded tube, and described carbon steel tubing and carbide reactor welded tube adopt bead-welding technology to be connected.
Electrolytic aluminum ladle aluminum pipe sucking of the present utility model, top is common suction aluminum pipe, and employing material is carbon steel.
The material of described common suction aluminum pipe is carbon steel.
Described build-up welder is formed by D802 welding rod, YD856 welding rod or other type hard alloy overlay welding.
The length of described build-up welder is greater than the height of electrolyzer.
The working method of electrolytic aluminium vacuum bag aluminum sucking pipe of the present utility model is:
1, utilize prior art, produce normal carbon steel pipe, as the upper part of inhaling aluminum pipe.
2, thin-wall ceramic pipe external diameter being equaled carbon steel tubing internal diameter inserts carbon steel tubing, using thin-wall ceramic pipe as support, annular built-up welding is carried out around thin-wall ceramic pipe with D802 welding rod, YD856 welding rod or other type Wimet, produce heat-resisting, corrosion-resistant build-up welder, as the lower part of inhaling aluminum pipe.The length of described build-up welder is greater than the height of electrolyzer.
For improving built-up welding effect and increasing strength of joint in aforesaid method, thin-wall ceramic pipe is supported as built-up welding inwall, and carries out annular built-up welding around it, after shaping, vitrified pipe is taken out.
The premium properties such as corrosion-resistant, heat-resisting of the cheap of carbon steel and D802 welding rod material (YD856 build-up welder) combines by the utility model, effectively can extend and inhale aluminum pipe work-ing life.Meanwhile, build-up welder length is generally only 10-20mm, and manufacture craft is simple, and the cost of material is low, and therefore this built-up welding suction aluminum pipe has very high cost performance.
