Abstract
The utility model relates to compound conductive connector made of casting steel, aluminium and copper, which is used in an electrolytic aluminum industry and is composed of a steel plate, a copper plate and an aluminium plate, wherein, a copper plate layer is wrapped and sealed between a steel plate layer and an aluminum plate layer, and the copper plate and the aluminum plate are cast and manufactured on the steel plate in sequence. The utility model has the characteristics that connection is tight, electricity conducting performance is good, energy consumption is less, anti-pull strength is big, service life is long, the utility model is safe without pollution, accident incipient fault does not exist, etc. When the utility model is used industrially, the production cost for the electrolytic aluminum industry can be reduced, and normal proceeding for producing is ensured.
Description
The utility model relates to a kind of steel aluminium and copper founding composite conducting joint, is the positive contact of aluminum electrolysis industry.
Usually, the used conductive contact of aluminum electrolysis industry is to adopt the compound welder of exploding to plant to make by steel plate and aluminium sheet to form.Compound weldering is enhanced to the weld strength of two kinds of different metals though explode, and does not form the congruent melting state at composite surface, causes it to have shortcomings such as poor electric conductivity, energy consumption height, tensile strength be low.In the actual production use, because the complexity of temperature changes, the coefficient of linear expansion of two kinds of metals is bigger, still has to separate the appearance of sealing-off phenomenon, has brought accident potential to safety in production.And the useful life of this conductive contact is short, energy consumption is high, causes production cost to increase, and has influenced economic benefit.
At present, copper aluminium founding composite conducting joint and steel aluminium founding composite conducting joint have appearred again in the sector.Wherein, because the joint face of copper aluminium founding composite conducting joint is a copper, can't satisfies with the steel plate that is connected of graphite and connect, so can not be applied to aluminum electrolysis industry as positive contact.And for steel aluminium founding composite conducting joint, the fusing point of invar aluminium differs greatly, and two kinds of materials can't be welded together.Now still adopt the method for mechanical connection founding, thereby the defective of the compound weldering of exploding exists still.
The purpose of this utility model is to provide a kind of conducting electricity very well, and energy consumption is low, and tensile strength is big, long service life, safe and reliable steel aluminium and copper founding composite conducting joint.
Steel aluminium and copper founding composite conducting joint described in the utility model is made up of steel plate, copper coin and aluminium sheet three ply board, and copper coin, aluminium sheet are poured into a mould on steel plate successively and made.
Between steel, aluminium, add transition bond---copper, carry out the bianry alloy binder course that chemical reaction generates respectively, three kinds of metals are combined securely by copper coin and steel plate, aluminium sheet.Fundamentally solved the seam difficult problem of two kinds of heterogeneity metals and because of welding insufficient poor electric conductivity that produces, energy consumption height, defective that tensile strength is low, safe and reliable, the useful life of having improved conductive contact greatly.In industrial application, can reduce the production cost of aluminum electrolysis industry, guarantee ordinary production, increase economic efficiency.
For fear of the pollution of copper, the copper coin layer can be encapsulated between steel plate layer and the aluminum layer.
Below in conjunction with drawings and Examples the utility model is further described.
The structural representation of Fig. 1, the utility model embodiment.
As shown in the figure, steel aluminium and copper founding composite conducting joint described in the utility model is made up of steel plate layer 1, copper coin layer 2 and aluminum layer 3, and copper coin layer 2 is encapsulated between steel plate layer 1 and the aluminum layer 3, and copper coin 2, aluminium sheet 3 are poured into a mould on steel plate 1 successively and made.
During making; basic unit selects steel plate 1 for use; put into mould after treatment; under the protection of inert gas, copper water is cast in the capaciting material groove of basic unit's steel plate; then aluminium water is cast on copper coin and the aluminium sheet; in the process of cast copper water, aluminium water, form steel copper binary alloy layer between the contact-making surface of basic unit's steel plate 1 and transition binder course copper coin 2 like this, formed copper aluminum binary alloy-layer between the contact-making surface of transition binder course copper coin 2 and multiple layer aluminium sheet 3.Successively basic unit's steel plate 1, transition binder course copper coin 2, multiple layer aluminium sheet 3 are connected into an integral body securely by steel copper binary alloy layer and aluminum bronze binary alloy layer, can be made into the steel aluminium and copper founding composite conducting joint of different size again by compacting and machine work.
From this, the utility model can not only satisfy the electrolytic aluminium anode instructions for use, as joint, also has connection tightly Close, good integrity conducts electricity very well, and energy consumption is low, and tensile strength is big, and long service life is safe and reliable, pollution-free etc. Characteristics, zero defects hidden danger. In industrial application, can reduce the production cost of aluminum electrolysis industry, guarantee normally advancing of production OK, increase economic efficiency.
