Description
Technical field
The utility model is related to a kind of welding equipment, more particularly to a kind of anode steel claw quickly repairs bonding machine.
Background technology
Anode steel claw is the running stores of aluminum electrolysis industry, and its effect is control anode block and conveys electric current.Due to sun
Pole steel pawl operating ambient temperature contains higher NaF liquid, electrolytic process more than 1000 DEG C, and in Bath
HF gases are discharged, anode steel claw is in the situation of high-temperature oxydation and HF gas attacks, and anode steel claw bottom about 100mm position is got over
Come thinner, it is shorter and shorter, until steel pawl can not be used.Because anode steel claw defect part only accounts for 15% or so of whole steel pawl,
Remaining stands intact, therefore each enterprise is in order to pursue economic benefit, will again be used after the broken parts reparation of steel pawl, with
Extend its service life.Specific way is to cut off anode steel claw broken parts, then with one section of isometric new rod iron using electricity
The method of arc-welding human weld is welded together, completes the reparation of steel pawl, then is used.
What the reparation welding of anode steel claw was used now has two kinds of welding methods.A kind of is manual electric arc welding's welding rod iron
Method.Another is the method that molten cast welding regenerates steel pawl defect part.
The method of manual electric arc welding's welding rod iron is to cut the part of anode steel claw corrosion oxidation scaling loss with oxygen-acetylene
Machine is cut off, by equal length with diameter rod iron to squeezing on the cut surface of steel pawl, by manual control arc welder or two
Carbonoxide protects outer rim of the welding machine along two rod iron places of connecing face to be welded to together.It is relatively enough strong in order to ensure to be welded with
Degree, will typically be welded two to three times.This welding method repairs speed relatively fast due to simple to operate, advantage of lower cost
Used by most enterprises, but the steel pawl of this method reparation has service life short, and the low shortcoming of conductance is difficult to overcome.
The method of founding weldering regeneration anode steel claw defect part is a kind of anode steel claw reparation about occurred before 5 or six years
Technology.The technology is by anode steel claw corrosion oxidation scaling loss Partial Resection, using small intermediate frequency heating furnace, by the sensing of heating furnace
Tubbiness pot is made in circle, is fixed on anode steel claw deleted areas, and wherein steel pawl cut place about 50mm part is contained in tubbiness pot, bucket
The hanging rod iron in shape pot top, the rod iron in body of heater is heated melt when induction furnace is begun to warm up, until molten steel filling is full
Whole body of heater, the part that steel nail-press is sliced off is full of with molten steel, after molten steel solidification after body of heater cooling, removes tubbiness pot, a steel
The Regeneration and Repair work of pawl is completed.The characteristics of this technology is the relatively preferable of welding fusion.Welding portion intensity is higher, repairs
The rod iron life-span afterwards is relatively long, but there is also manipulation difficulty greatly, repair time is long, and power consumption is big to wait fatal defects without by not
Received by enterprise.
The method of manual electric arc welding's welding rod iron is although simple and easy to apply, is used by most enterprises, but also have following fatal
Shortcoming：
A. steel pawl service life is short.Because two rod irons can only be welded in the outer rim of its contact surface, even if welding two
To three times, it is welded, and meat thickness is also very limited, and under the collective effect of high-temperature oxidation and corrosion gas, weldering meat is thinning quickly, welding
Rod iron up easily comes off, and the steel pawl come off can only return to salvage shop and carry out repairing welding again.According to our investigation,
The steel pawl service life of this method welding only has one to two electrolysing periods, and an electrolysing period is generally 28 days.Therefore it is big
The steel pawl of amount, which repairs welding job, turns into the burden of each enterprise.
B. conductance is low.One important function of steel pawl is conductive, because this method is only carried out in contact surface outer rim
Welding, that is, its area of part that steel pawl is really welded together only have 10 or so of rod iron sectional area, as leading
Its conductive cross-sectional area of electric body is had a greatly reduced quality, and this just increases resistance, causes its conductance also to be had a greatly reduced quality.
C. consumption of materials is big.Due to each steel pawl different, heap everywhere after it comes off that welds rod iron length up
Put, be difficult to find suitably sized correspond to weld when repairing welding again, reused, therefore general enterprises are not
The rod iron come off in reuse, this results in very big waste.Oxygen, acetylene, dioxy repaired for steel pawl simultaneously necessary to
The consumption for changing the materials such as carbon gas, various wldings is also extremely surprising.
D. it is artificial to waste big.Investigated through us, by taking 50 steel pawl heads of daily reparation welding as an example, including steel nail-press is cut, rod iron
Cut, steel pawl welding etc. needs 30 people to divide double-shift work to complete.It is small that each electric welder's welding completes a steel pawl head needs 1
When or so time, therefore it is artificial waste very big, efficiency is very low.
The major defect of founding weldering regeneration steel pawl technology is as follows：
A. time-consuming.This method welds a steel pawl head, and even dress band is unloaded the time of 60 minutes or so that needs, time-consuming oversize.
B. power consumption is big.This method is welded a steel pawl head power consumption more than 300 and spent, and often spends electricity by 0.45 yuan of calculating, only electric
Take a yuan of needs 135, cost is too high.
C. welding success rate is low.The steel pawl that this method is repaired is big due to solder side fusion difficulty, is difficult to control, after use
Easily come off, repair rate is high.
D.. efficiency is low：One such machine needs 5 to 6 people nurse.7 to 8 steel pawls, efficiency pole can only be repaired within 8 hours
It is low.
Therefore due to above major defect, this equipment enters behind market, eliminates idle by each enterprise quickly, then use
The method reparation welding of human weld.
The reparation of anode steel claw is welded in aluminum electrolysis industry due to no more advanced reliable welding equipment of appearance, and
Production is generally maintain using the method for manual electric arc welding's REPAIR WELDING.The steel pawl service life that this method is repaired is short, repeats
Reparation amount is big, and greatly, artificial mechanism consumption is big for consumption of materials, and it is tired very that the shortcomings of steel pawl volume of traffic is big turns into each aluminium electrolysis enterprise
Tired stinker, and cannot solve well for many years, this seriously constrains the technological innovation and development of enterprise.Therefore I
Invention anode steel claw quickly repair welding machine be exactly in order to can solve problem above, be that the development of enterprise is added enthusiasm.

Technique effect
As it was previously stated, the method that human weld repairs steel pawl, simply in two rod iron contact surface outer rims, with electric welding or dioxy
Change carbon protection weldering, built-up welding twice three times, its area being really welded together only has 1/10th or so of rod iron sectional area, its
Intensity and its limited, the steel pawl after reparation is in the environment of electrolytic cell high temperature high corrosion, and the weldering meat of Electric Welding Buttering Technique is oxidized quickly
Erode, can only use 1~2 month；Steel pawl is used as conductive conductor in a cell simultaneously, tens of thousands of amperes
Electric current passes through from rod iron junction, because the sectional area being really welded together is 1/10th of rod iron sectional area, therefore leads
Electric sectional area is had a greatly reduced quality, and then its conductance is also had a greatly reduced quality.Further, since repair machine service life is short, steel pawl needs anti-
Multiple repair is welded, the rod iron required for reparation welding process, oxygen-acetylene, carbon dioxide, and the material such as welding rod welding wire is caused
Greatly waste, while also resulting in greatly artificial waste.A kind of anode steel claw for making founding weld that in the market occurs in recent years
Regeneration techniques, also due to manipulation difficulty is big, performance is unstable and withdraws from the market.
By the experimental study of nearly 2 years, the anode steel claw that we design quickly repair bonding machine it is extraordinary solve with
Upper problem.It has following feature, existing analytic explanation.
A, speed of welding are fast.It is real there was only 90~180 seconds with the time in welding between, count in handling and pressurize when
Between, averagely welding a steel pawl head only needs 10 minutes, 8 hours solderable nearly 50 steel pawl heads of a machine-team, with obvious
Speed advantage.
B, the steel pawl service life repaired are long.This welding manner is that two rod irons are integrally welded together, that is,
The sectional area of bonding area and rod iron is equal.High temperature oxidation corrosion resistance ability and rod iron are one in itself in use for it
Sample, said from this angle, the steel pawl life-span of this mode REPAIR WELDING and new steel pawl are the same.In addition, we are grinding
During studying carefully, the steel pawl being welded is placed on forcing press shear pressure experiment is carried out to weld seam, by the experiment number of more than 200 times
According to display, the anti-shearing pressure of weld seam is all more than 250 tons, and this has been more than the 90% of steel pawl mother metal anti-shear ability,
This absolutely proves that this mode welds the superiority of steel receiving grab.
C, conductance are high.The critical function of anode steel claw in use is used as conductor, conductance
Height be anode steel claw an important indicator.As it was previously stated, the steel pawl of this welding manner welding, bonding area and steel pawl
Sectional area is identical, that is, the conductive cross-sectional area as its commissure of conductor is identical with steel pawl conductive cross-sectional area, therefore weldering
Other position conductances are consistent to conductance at seam with steel pawl.This conductance compared with the weld seam of Manual electric welding built-up welding has
Absolute advantage.
D, material consumption are low.Because the steel pawl service life of this method REPAIR WELDING is improved, the repetition reparation of steel pawl
Number of times is greatly reduced, rod iron necessary to steel pawl is repaired, welding material such as welding rod welding wire, carbon dioxide, cutting of steel pawl
Must the material such as oxygen-acetylene gas substantially reduce.This welding manner is that mother metal is directly welded simultaneously, is not consumed
The materials such as welding rod welding wire, carbon-dioxide protecting gas, by we and aluminium industry related personnel's statistical analysis, this welding manner with
Original human weld's mode is compared, and can save about 80% material consumption.
E, manpower consumption are low.By taking the aluminium electrolysis enterprise steel pawl salvage shop of Gansu as an example, the workshop amounts to 25 production people
Member, point double-shift work, the steel pawl completed daily repairs task average out to 50 or so, and steel pawl 2 is repaired per capita.The steel that we design
Pawl repairs bonding machine and only needs to 3 operators, and daily weldable steel pawl 50 or so adds the cutting rod iron cutting of steel pawl
3 workmans and the management people of support personnel 1 are needed, altogether 7 people, steel pawl is repaired per capita more than 7, therefore man efficiency is very
Substantially.
