Description

One kind manufacture metallurgical binding ply-metal Processes and apparatus

Technical field

The invention belongs to field of compound material, and in particular to one kind manufactures metallurgical binding ply-metal technique and sets It is standby.

Background technology

Composite metal plate can be different with the kind of facestock according to base material, are prepared into the composite plate of various materials.Including:Steel/ Steel composite board, the steel composite board of stainless steel one, the steel composite board of copper one, the steel composite board of aluminium one, the steel composite board of titanium one and aluminium/titanium, fine silver/ Noble metal composite plate such as silver alloy etc., can be widely applied to the fields such as shipbuilding, aerospace building, electronics, chemical industry, machinery.It is wide It is general to be applied to space flight and aviation, military project, atomic energy, national defence and metallurgy, building materials, ship, oil, chemical industry, power system, electronics device In many fields such as part, machinery, automobile, thermal energy conduction, pharmacy, food, information, civilian.

The production method of current composite metal plate can be divided three classes：Gu a solid phase, liquid-liquid phase and the solid phase composite algorithm of liquid one. Industrial production mainly uses compound casting, Explosion composite and composite technique for rolling.Wherein, casting combination process is by a kind of matrix (solid phase) and another matrix (liquid phase) are combined in mold, and composite is formed after solidification.In proper temperature and pressure Combined strength bination high can be obtained down, be suitable to produce the blank of some metallic composites.Current double metallic composite material is cast as Shape technique can be divided into 3 classes：Covering and casting, double fluid casting and centrifugal casting technique.Other combination process also have casting rolling method, inverse To freezing method.At present still in the laboratory research stage, without industrialized production launch.

Disclosed 1. Chinese invention patent application number is 200710011271.7 entitled systems by literature search The production method of copper clad aluminum wire is made, the production method step is cleaning copper pipe inwall, and coats layer protective layer；In inert gas Under protection, copper pipe is heated, casting motlten metal aluminium in it；Copper cover aluminum base is formed copper clad aluminum wire and be combined through rolling, drawing Strip.The method has the disadvantage that：First, pretreatment procedure is complicated, and single production copper cover aluminum blank, low production efficiency, It is difficult to form continuous prodution, production cost is high；Second, casting process is complicated under protective gas, working environment is poor；Its Three, copper cover aluminum base is cooled down again without long-time heat preservation, and phase counterdiffusion is insufficient between bimetallic constituent element, is not formed to a certain extent Good interface cohesion, reduces interface bond strength.2. Chinese invention patent application number is 200810057668.4 invention names Referred to as a kind of high-performance cooper-coated aluminum rectangle section compound conductive bus row and its preparation technology, the technique are direct using horizontal casting Composite forming copper cladding aluminum composite blank；By copper cover aluminum base by rolling, drawing, again rolling mill practice be finally made copper clad aluminum wire.This The shortcoming that technique is present is essentially consisted in：It is high to equipment requirement, copper clad aluminum wire horizontal continuous casting equipment complex structure, manufacturing cost compared with Height, so as to improve the manufacture difficulty and manufacturing cost of copper-clad aluminum composite panel belt.Chinese invention patent application number is 00806525. In x, there is provided a kind of composite sheet material for brazing, it is coated on metal base after solder bonding metal feed powder end is mixed with organic matter, Soldering flitch is made, for the controlled atmosphere soldering of aluminum device.But, the compound needle material at this coating solder bonding metal feed powder end After organic matter volatilization, solder powder has the possibility for coming off to plate, it is impossible to ensure the uniformity and of solder thickness and Mass Distribution Even property, causes welding device locally to have the possibility of solder skip or burn through, it is necessary to locally be mended to the solder skip or burn through of welding assembly Weldering, so as to increased the manufacturing cost of device weight and device.

Just at present from the point of view of domestic and international ply-metal achievement in research, the composite plate prepared by it belongs to greatly non-metallurgical junction Conjunction state, makes the material show some problems, such as lacks metallurgical binding between two kinds of materials, it will cause that coating is too early to be opened Split, greatly reduce the corrosion resistance of material；The quality control of material, such as coating thickness it is uneven, inside is likely to occur corruption Erosion, makes the mechanical behavior of material indefinite.Above mentioned problem it is short-term and it is long-term in be likely to result in serious consequence.

Pursuing resource minimal consumption, benefit maximum today for obtaining, the premium properties having by composite plate and good Good energy-conservation knot material effect is increasingly favored by people, in order to meet the market demand, improve production efficiency, it is ensured that product matter Amount, reduces production cost, improves input and output qualification rate, must just be had breakthrough in technology, and finding one kind can make life The method for producing maximizing the benefits.Therefore research and development novel dual metal composite plate manufacturing process is to realize high-performance metal composite wood Material high-quality, low cost, the key of high efficiency production.For reducing engineering cost, engineering construction quality, extension engineering knot are improved The service life of structure is significant.With wide market development prospect.
