Description
Technical field
The invention belongs to the preparation field of double metallic composite material, specifically the method for double metallic composite material is prepared in copper material solid-liquid composite casting and drawing combination, particularly a kind ofly prepares the method for double metallic composite material by drawing group technology after solid-liquid composite casting.
Background technology
Along with the development of modern industrial technology, more and more higher to the requirement of material combination property, under a lot of working condition, the metal material of single constituent element has been difficult to meet the demands.Double metallic composite material makes by various complex technique metal composite a kind of advanced composite material (ACM) of preparation together that two kinds of performances are different.Compared with the metal material of single constituent element, double metallic composite material can fully utilize two kinds of metal materials physicochemical characteristics separately, obtain the combination property that single constituent element metal can not have simultaneously, the fast development of industry and science and technology can be met preferably for the more and more higher requirement of material.Copper material is due to its excellent conduction, heat conductivility, and good mechanical property, by development and application widely in individual industrial circle.Find through investigation, the bimetallic material that between copper material with other materials prepared by compound is same receives increasing attention.As Cu-Al bimetal composite combines the light weight of the high conduction performance of copper alloy, high thermal conductivity, low contact resistance and aluminium, the advantage such as anti-corrosion.Cu-Al bimetal composite can be issued to the high connductivity very nearly the same with copper material, thermal conductivity in the prerequisite alleviating 40% weight, and price only has 60% of copper material simultaneously.Current Cu-Al bimetal composite products mainly contains: cuprum-cladding-aluminium composite wire, Copper-Aluminum compound joint material and Copper-Aluminum compound strip.Cu-Al bimetal composite has been widely used in the fields such as electric power, electronics, electrical equipment, automobile, the energy.In addition, along with the fast development of economic construction, it is also maximum copper resource importer that China has become copper products producing country maximum in the world, needs the copper resource that import is a large amount of every year, and the continuous rising of copper processing have impact on the economic benefit of domestic enterprise.The use of generic double metallic composite material can be optimized allocation of resources very well, increases economic efficiency, and has boundless application prospect.
When using traditional welding method to prepare double metallic composite material, due to physical property between copper alloy and aluminium alloy as fusing point, specific heat capacity, linear expansion coefficient etc. differ greatly, the thermal conductivity of two kinds of metals is all fine simultaneously, so often there is a series of problem such as oxide slag inclusion, air-breathing, hot tearing, component segregation in welding process.Through finding the retrieval of prior art, the method that between copper aluminium, compound is common except welding method can be divided into solid-liquid compound, admittedly compound and liquid liquid compound according to the difference of materials behavior.For being admittedly solidly connected method, as drawing, production efficiency is higher, but because copper and aluminium are all very easy to oxidation under atmospheric environment, especially under hot conditions, all can form fine and close oxide-film between two kinds of metals, the existence of oxide-film seriously can hinder the interaction between two kinds of metals, worsen quality of connection, be not easy to form good metallurgical binding.Connect for liquid liquid and be then often subject to the restriction of equipment, have very strict requirement for the profile of material, size, this also limits the promotion and application of Cu-Al bimetal material to a certain extent.Solid-liquid compound is little by form factor constraint, process equipment requires simple, but easily on interface, generates thicker intermediate compound when pouring temperature is higher, affects bond strength and the physical property of Cu-Al bimetal composite.Each method has its distinctive advantage, but has certain limitation.
Find prior art retrieval further, researcher begins through two kinds of complex methods and combines and prepare Cu-Al bimetal composite to overcome the deficiency of single method.Chinese patent CN102626854A discloses a kind of method that blast adds the full copper-clad aluminum composite bar of Rolling Production.The method that this technology utilizes explosive welding to add rolling combination has prepared Cu-Al bimetal composite, two kinds are utilized admittedly to be solidly connected method in technique, surface does not have specially treated, so two kinds of metal interfaces can exist oxide-film, simultaneously higher for the shape requirement of material.Chinese patent CN101364459A discloses a kind of production method and equipment of copper-clad copper bus bar.This technology utilizes the method for extruding and hot rolling combination to prepare Cu-Al bimetal composite; but owing to being utilize two kinds to be admittedly solidly connected method; and in order to avoid the impact of oxide-film, in heat treatment process, introduce inert gas shielding, require higher for equipment and preparation condition.
Summary of the invention
For defect of the prior art, the object of this invention is to provide a kind of copper material solid-liquid composite casting and the method for double metallic composite material is prepared in drawing combination, solving when existing complex technique connects copper material and other material often causes calmodulin binding domain CaM to form the problem of oxide slag inclusion, air-breathing, hot tearing, component segregation, the existence simultaneously solving oxide-film and intermediate compound has a strong impact on a series of problems such as the performance of interaction between two kinds of metals and double metallic composite material is lower, make to form metallurgical binding between two kinds of alloys, there is excellent mechanical property.
