Abstract
The present invention discloses a fusion casting and welding method for an aluminum mother plate, and decontamination, oil removal and oxide film removing treatment are carried out on the surface to be welded of the aluminum mother plate. Scaling powder is coated on the surface to be welded of the mother plate, and according to the shape and the requirement of a joint, fire resistance flame retardance materials are made into a fusion casting chamber on the position of a welding joint; the aluminum mother plate is preheated, after the temperature of the aluminum mother plate reaches to 100 to 200 DEG C, aluminum and an aluminum alloy which are prepared to a scale are heated and melted by a smelting device, and fused aluminum alloy liquid is cast in the fusion casting chamber; mother plate metal is melted by using the high temperature of fused metal, and meanwhile, a welding line is filled, so a welding method for welding is realized. The welding method solves the puzzle of the welding of an aluminum bus in a strong magnetic field, a damaged bus of an aluminum cell can be electrically welded ceaselessly, and thus, the production of electrolytic aluminum can not be affected.
Description
Technical field:
The present invention relates to a kind of fusion casting and welding method of aluminum mother plate.
Background technology:
In Aluminum Electrolysis Production, for improving the output of current efficiency and aluminium, the current strength of aluminium cell is in rising trend, and the current strength of present domestic aluminium cell has reached 320KA.So big DC current makes electrolytic cell and has produced high-intensity magnetic field on every side, and magnetic field intensity surpasses 150GS.Conductive aluminum bus regular meeting's accidental damage aborning of electrolytic cell; the main at present direct current metal argon arc welding machine that adopts carries out REPAIR WELDING, but this welding method is very responsive to magnetic field, when magnetic field intensity surpasses 20GS; because strong arc magnetic blow can not normally be welded.For can REPAIR WELDING aluminium busbar, have only the back that will whole electrolysis preface series has a power failure with direct current metal argon arc welding REPAIR WELDING, electrolytic cell preface series has a power failure and has not only caused bigger economic loss, the ordinary production of aluminium cell is caused to have a strong impact on simultaneously.So technical barrier anxious to be solved of the aluminium busbar solder technology aluminium electroloysis industry always in the high-intensity magnetic field.Some relevant enterprises are for solving this difficult problem both at home and abroad, a lot of tests and exploitation have also been carried out, as the direct current metal argon arc welding under magnetic field cancellation and the magnetic field shielding, Laser Welding, ratio-frequency welding, thermofussion welding, thermit welding etc., but these methods all have some defectives, drop into practical application seldom.
Summary of the invention:
The objective of the invention is to: a kind of welding method that solves an aluminium busbar welding difficult problem in the high-intensity magnetic field is provided, realizes that aluminium cell damages the welding that do not have a power failure of bus, to address the above problem.
The present invention is achieved in that
The founding welding technique of aluminium busbar is:
1, aluminum mother plate position to be welded processing is neat;
2, according to the shape of mother metal needs welding point to be welded, make the founding chamber in joint location.The founding chamber is to make anchor clamps by steel plate.In anchor clamps, put into fire resistant flame retardant materials such as asbestos board.The fire resistant flame retardant material is the mixture or the asbestos cord of asbestos board, waterglass and asbestos wool.
Behind the last clamper, again place, the slit between steel plate and the aluminum mother plate to be welded is filled out the mixture or the asbestos cord of waterglass and asbestos wool, thereby make its sealing, can not spill aluminium liquid.The shape in founding chamber can be cuboid or terrace with edge.
Why will add the fire resistant flame retardant material at surface of steel plate, be because these materials have heat insulating ability and elasticity preferably, can make the founding chamber insulation of making, and go up the seepage that does not have aluminium alloy behind the clamper between the steel plate and aluminum mother plate to be welded.
3, mother metal to be welded surface is removed contamination, oil removing, smeared scaling powder, removes oxide-film and handle.
4, weld mold is installed, is checked the sealing of mould, guarantee can not spill aluminium liquid;
5, join casting and use aluminium alloy, according to its weight proportion: silicon 5-15%, copper 1-10%, aluminium 94-75% calculates the consumption of various raw materials, and the weight of weighing aluminium alloy guarantees that the composition of alloy meets the welding point needs.
6, aluminium alloy is carried out melting, casting is 500-600 ℃ with the fusing point of aluminium alloy, and aluminum alloy melt is heated to 800-1300 ℃ always.
7, to being carried out preheating by the weldering aluminum mother plate, preheat temperature is 100-200 ℃.
8, with aluminum alloy melt from the cast on top of weld mold in welding founding chamber, because of the fusing point of aluminium is 600-630 ℃, thereby cools off with aluminum alloy melt again after will the aluminum mother plate fusing and finish welding procedure.
9, after connector temperature to be welded is lower than 50 ℃, take off weld jig.
The present invention compared with prior art has the following advantages:
1, overcome in cell room, since strong arc magnetic blow, the difficulty that can not normally weld.
2, owing to the continuity of Aluminium Electrolysis, it is very big to the influence of production to have a power failure.The present invention has realized the welding that do not have a power failure to aluminium bus of electrolyzer, has produced very big economic benefit.
Description of drawings:
Accompanying drawing 1 is a process chart of the present invention.
The specific embodiment:
Embodiment one:
The electrolysis plant aluminium busbar is welded:
1, aluminum mother plate position to be welded processing is neat;
2, according to the shape of mother metal needs welding point to be welded, make the founding chamber in joint location.The founding chamber is to make anchor clamps by steel plate.In anchor clamps, put into fire resistant flame retardant materials such as asbestos board.The fire resistant flame retardant material is the mixture or the asbestos cord of asbestos board, waterglass and asbestos wool.
Behind the last clamper, again place, the slit between steel plate and the aluminum mother plate to be welded is filled out the mixture or the asbestos cord of waterglass and asbestos wool, thereby make its sealing, can not spill aluminium liquid.The shape in founding chamber can be cuboid or terrace with edge.
Why will add the fire resistant flame retardant material at surface of steel plate, be because these materials have heat insulating ability and elasticity preferably, can make the founding chamber insulation of making, and go up the seepage that does not have aluminium alloy behind the clamper between the steel plate and aluminum mother plate to be welded.
