Description
Technical field
The invention belongs to the materials processing technology field of metal clad plate strip, be specifically related to a kind of method of rolled metal complex plate strip.
Background technology
Along with the fast development of science and technology, the birth of a collection of high-new art industry, higher levels of requirement is proposed to the serviceability of material, simultaneously in order to reduce costs, saving resource, reduction energy consumption, to enhance product performance, Chinese scholars is devoted to the novel bimetallic of research and development or multi-metal composite board material and rolling new technology.Metallic composite technology can play group element material advantage separately, realize the allocation optimum of each group element material resource, save precious metal material, realize the unappeasable performance requirement of single metal, be mainly used in anticorrosion, pressure vessel manufacturing, electricity built, petrochemical industry, medicine, light industry, automobile, shipbuilding, power, the industry such as desalinization.Laminar composite has the comprehensive mechanical property far above component, and in recent years, the research of this respect becomes one of focus of domestic and international new material research day by day, and wherein comparatively active is the research of metal laminate plate.Adopt two or more metal material, the composite board made with various different process, the combination property requirement of different commercial Application can be met.In this case, the development of composite, production and application more and more show its consequence.The compound of the compound of material, especially different metal materials, the exploitation for multifunctional material provides a new technology approach.
The U.S. in 1956 take the lead in proposing the three step process of metal laminate compound, that is: surface treatment-Rolling compund-multilayer metal compound Theory and technology, layer metal composite plate production technology and the process of new technology annealing strengthening, this technology makes bimetallic Room Temperature Solid State compound obtain to develop rapidly.The research of the former Soviet Union to laminar composite starts from the thirties in 20th century, and mainly adopt the methods such as rolling, casting, explosion method to produce the composite of the Metal and Alloys such as aluminium, titanium, steel, the research especially in cold rolling compound is more deep.Also there are suitable level in English, method, De Deng developed country to the research of composite, and wherein Birmingham, GBR university has carried out comparatively systematic research in 20th century five, the sixties to solid phase compound, achieves a lot of achievement.At present, metallic composite is widely used in these countries.The research of Japan in composite is started late, but its development is very rapid, has become one of country being engaged in metal composite most study in recent years.After the nineties in 20th century, a lot of achievement is achieved to the compound research of stainless steel and aluminium, applied for multinomial patent, especially in staged heating compound and warm-rolling compound, achieve the achievement in research attracted people's attention.
The domestic research to layered metal composite material starts from early 1960s, domestic dissimilar metal clad plate mainly adopts the mode of production to have bag to water (solid-liquid combination)+roll-bonding method, Explosion composite method, diffusion composite algorithm, explosive welding+rolling (cold rolling, hot rolling) composite algorithm and roll-bonding method etc., but also has a certain distance in plate shape, bond quality.Chongqing Iron & Steel Corp. in 1958 produces stainless steel clad plate with Hot rolling and obtains successfully, and nineteen sixty-five, Shanghai Metals research institute carried out the research of cold rolling solid phase complex technique, within 1972, built up a cold rolling solid phase composite production line.The cold rolling solid phase compound that countries in the world extensively adopt has that Product Precision is high, stable performance, compound constituent element kind select the various features such as unrestricted, but also there is solid phase and combine the shortcoming that required critical deformation is large and rolling load is high, a large technical barrier of wide-thin specification composite plate rolling that Here it is.1986, Northeast China university developed gradient-heated Rolling compund new technology, for Liao Xin road is started in the rolling of wide-thin specification composite plate.But never solve the template warpage that dissimilar metal mechanical property difference causes, the problem that residual stress is large.
Bag waters (solid-liquid combination)+roll-bonding method, the general principle of centrifugal casting is placed in (i.e. the mould) of rotation by quantitative liquid state, make it rotate around single shaft high speed, namely the material now put into is centrifuged power and forces and the nearly wall portion position being distributed in mould.Process characteristic is plate slab, the chemical composition segregation that centrifugal casting is produced is its fatal shortcoming, and the strand produced is that annular also needs cutting, heating, alignment could hot rolling, and poor product quality, production process are many, power consumption is large, processing cost is high.The general principle of Explosion composite method is the energy utilizing explosive charge to produce, and makes two pieces of metallic plates produce up to the strain rate of 106 ~ 107/s and the high pressure of 104MPa at the point of impingement, thus realize the welding compound of dissimilar metal within the Microsecond grade time; The technological advantage of Explosion composite method is, the very greatly different metallic combination of difference in material properties can be made to realize compound; The generation of brittle intermetallic thing can be avoided; Flexibility is strong, can realize the compound of various profiled piece; The bond strength of composite is high, is applicable to most ductile metal or alloy; But Explosion composite method interface bond strength is uneven, Percentage bound is low, easily crack, the defect such as shrinkage cavity and pore, in addition, this technique also exists that mechanization degree is low, working condition is poor, have certain danger, bring serious pollution to environment, Explosion composite normal plane is faced by the trend of eliminating gradually.Diffusion composite algorithm, owing to having the shortcomings such as long diffusion time, limited product size and lower interface bond strength, is not suitable for the suitability for industrialized production of large scale complex plate strip.Blast-rolling, because explosive forming is difficult to acquisition perfectly in conjunction with effect, for avoiding rolling defect, composite plate rolling breaker roll temperature, roll shape, lubricating condition, blank rotary shift time, pass reduction control overflow are strict, control badly to there will be edge crack, pony-roughing pass cladding ftractures, and template is overproof, the defects such as dimension overproof, cause blank to be scrapped; By the impact of explosion cladding process and rolling deformation technique and plied timber deformation characteristic difference, there is internal stress in composite plate in whole production procedure, produces bending, the bent or crimp of wooden dipper; Treatment of mat before blast, after blast, after rolling and product handling system all need leveling operation; The unevenness difference of cladding slab of blast causes that local, blast gap is super outstandingly affects explosive effect, and treatment of mat injustice of exploding is difficult to assembly, to cause in rolling blank can not Uniform Flow; Even if finished product sheet material leveling can not control horizontal convexity, can only the smoothing of heavy reduction brute force be strong repeatedly rectifys, cause partial fracture, the mechanical property of dissimilar metal differs greatly simultaneously, and the complex plate strip that rolling obtains wafts Qu Yanchong, and residual stress is large.
Adopt rolling mill practice to produce layered metal composite material, being better than the technique such as explosive welding (EW), diffusion welding (DW), is a kind of very economical and practical method.At present, roll-bonding method is the development trend that composite plate manufactures, and has the feature such as higher productivity ratio, low stain, low energy consumption.The general principle of roll-bonding method is under the effect of draught pressure, make two-layer or stacked conducting plate produce plastic deformation simultaneously, surface metal-layer breaks, expose cleaning and the metal activated, thus make to form metallurgical binding between plate face, in follow-up heat treatment process, by thermal diffusion, interface cohesion is strengthened and firmly further; Roll-bonding method can be divided into method hot rolling, cold rolling compound, its technique is generally divided into three steps: surface treatment, Rolling compund and heat treatment, the key of roll-bonding method technique is: clean and have the interface of certain roughness, enough large pressure and plastic deformation, suitable thermal diffusion.Process characteristic is that Rolling compund can carry out continuous seepage, and product size is accurate, and the thickness of each constituent element is even, stable performance, and the metal being suitable for Rolling compund is very many, and production cost is low, efficiency is high, is easy to realize large-scale industrial production; Method hot rolling method is that metal stock to be composite is heated to uniform temperature, applies large drafts be rolled distortion to it, while heat and power, make different metal be able to a kind of process of compound under effect; Relative to other combination process, the advantage of method hot rolling method is: roll-force is less, less demanding to milling train; Technique is simple, and cost is low; Interface cohesion is firm.Shortcoming is: when composition metal is active metal (as Al, Ti), easily forms the intermetallic compound of fragility during heating at interface; As not having Insulation during rolling, the length of clad metal sheet is restricted; The thickness of composite plate is difficult to control, conformity of production and poor stability, is suitable for producing thick composite board and slab more; The compound interface oxidation in the operation of rolling of method hot rolling method is difficult to avoid, and easily forms brittle metal compound, is easy to the interface bond strength weakening composite plate.Cold rolling composite algorithm, cold rolling combination process can become the composite wood production line of continuous-flow type production rolling in conjunction with process combination such as cleaning, brush finish, heat treatments, production efficiency is high; Before compound, the surface need polluted by method removing sheet material that is chemical or physics; Cold rollingly take a time large deformation rate, to reach the critical strain rate of metal, realize the metallurgical binding between double layer of metal atom, then realize the further diffusion between metallic atom by diffusion heat treatments, strengthen interface binding power.Roll compound Deng roller quick-coolings such as roller footpaths is first begun one's study by the U.S. the 1950's, proposes with " surface treatment+cold rolling compound+diffusion annealing " three-step production process, the seventies, asymmetrical rolling started the production for composite plate, claimed asymmetrical rolling composite algorithm, and by corresponding with quick roll for harder metal, softer metal with roller is corresponding at a slow speed, deformed area forms Cuo Zha district, increases bond strength, cold rolling compound belongs to pressure welding, the welding process that general reference metal carries out below recrystallization temperature, in principle, all metals with enough ductility can by cold rolling acquisition composite wood, and its bonding mechanism has " energy battier " and " superficial layer crack " two large class, in brief, the most metals surface in normal atmospheric environment all by which floor superficial layer covered, and they can stop the compound of metal when two surfaces contact with each other, so, make two metal rolled compounds, propose and make oxide skin(coating), search three kinds of mechanism that cap rock or pollution layer break, for two kinds of metals that yield strength difference is larger, in the operation of rolling, faying face near zone will there will be Relative sliding, therefore, the plastic deformation of these two kinds of metals is uneven, this just means, two kinds of relative superficial layers are assumed to be jointly to break as same layer be cannot stand, according to Continuum Mechanics analysis, calculate each metallic surface exposure, obviously, the exposure of the two is differentiated, bond strength then and between surface plastic deformation rate and pressure has functional relation, production low-intensity, high-ductility, oxidizable, high-precision composite plate, cold-rolling practice is adopted to be feasible.
Current Problems existing:
L) the cold rolling composite plate rolling for not forming brittle intermetallic thing, can give full play to the high efficiency of milling train, working condition is good, and production specification is flexible, especially seems superior especially for thinner composite plate; By the restriction of rolling technique and condition, rolled parts is usually in the condition of high temperature under large deformation, so combined material brings serious plate shape problem because of the difference of different melting points, hardness (plasticity) difference and Thickness Ratio size; In order to reach cold rolling object, though adopt asynchronous rolling machine rolling composite plate to achieve certain success, when milled sheet changes, due to the difference (single driving machine) of upper and lower roll pressure, then composite plate combined transformation is uneven up and down, can cause thickness out-of-size time serious;
2) principle of Rolling compund is substantially similar to pressure processing, before non-compound, two metals cause the difference of plastic deformation rate from the teeth outwards because mechanical property is different, the difference of linear expansion coefficient, result in the defects such as the residual stress of land, this is different from monometallic rolling, due to the difference of the mechanical property of dissimilar metal own, its deformability is also different, the deformation extent of the metal causing resistance of deformation little is greater than the deformation extent of the large metal of resistance of deformation, therefore, distortion in deformed area is inconsistent, make to there is additional stress in the composite board band after rolling, there is additional compression in the side that deformation extent is large, there is additional potential stress in the side that deformation extent is little, make in contact in rolling, stress distribution is seriously uneven, the composite plate produced certainly leads to bent and very large residual stress of seriously wafing, cause rolling composite plate defective, easy cracking.
Publication number is a kind of method that the patent application " method of composite metal plate is prepared in engagement type vacuum rolling " of CN10327842A discloses engagement type vacuum rolling and prepares composite metal plate, the method composite billet be on the composite surface of substrate and cladding plate, process the substrate bumps that cooperatively interacts respectively and cladding plate protruding, machined is wanted to obtain, machined tooth needs to heat-treat metal in advance, otherwise machined produces tooth and has crackle, this not only adds cost, nor meet the technique of hot rolled plate composite plate base; The surface of the tooth of mach generation can because of and processing temperature high and produce metallographic structure change in metal surface and have residual stress very greatly, such tooth surface can have a strong impact on binding ability and the bond strength of composite plate multi-layer and basic unit, machined tooth on metal slabs, metal slabs size is restricted, with current tooth machining center, still can not complete, not attainable, and this dentation is concerning the steel rolling process that will produce in batches, extremely difficult processing, even cannot process intermeshing dentation; This composite billet engages on faying face, after rolling with do not slot composite plate compared with, effectively solve distortion problem of non-uniform, the serious uneven situation of stress distribution in the recombination process of the different metal of two kinds of yield strengths, certainly lead to the residual stress that serious wooden dipper is bent and very large after rolling, cause rolling composite plate defective; The dentation of this band wedge angle, fill in shape process at metal and easily produce space, known by theory analysis and test, very easily produce pipe and crackle when rolling, run counter to contact in rolling law of metal flow, the product of this method rolling simultaneously has very large residual stress, product quality can not meet existing standard, therefore this technology cannot be promoted so far aborning, does not also have any social benefit, does not possess operational feasibility.
In sum, in dissimilar metal Rolling compund problem, all there is the composite plate combined strength bination caused greatly because of different metal materials mechanical property difference low, recombination rate is low, serious warpage and the large problem of composite board internal residual stress.So make dissimilar metal interface cohesion firm, Mass accuracy is high, variety range is wide, recombination rate is high, plate shape good (do not waft song, and residual stress is little), production efficiency height is composite metal plate production problem demanding prompt solution, at present, need a kind of effective technology badly and solve these problems, widely popularize the production method of Rolling compund strip.Inventor's deformation mechanism continued to performance difference in larger metal rolled recombination process on the basis of patent applied for (license notification number CN103736728B, CN103736729B) has carried out a large amount of theoretical experimental analyses, utilize the interaction of constituent element in towing deformation theoretical qualitative analysis deformation process, instruct on dissimilar metal compound engagement face and done further research.
