Technical field
The present invention relates to the compound production method of a kind of bimetallic, relate in particular to a kind of production method of copper steel composite board.
Background technology
Metal material plays a leading role in producing and using as the chief component of material.Yet progress of science and technology is increasingly high to the metal material performance demands, and single metal material can't satisfy these needs.And, in production practices,, must use very expensive non-ferrous metal and other Rare Metals Materials for satisfying the needs of making the special engineering structural behaviour.In order to make metal material give play to the performance that it had to greatest extent, one of its method is exactly to make up the performance material different to process composite.
Copper/steel composite material not only has the special performance of copper, but also has the intensity and the mechanical performance of steel, thereby obtains anticorrosion, resistance to wears, electrical and thermal conductivity is good, attractive in appearance, excellent comprehensive performances such as cost is low.It makes part that arranged long service life, than single copper product higher intensity, hardness is arranged, and is not yielding, has improved bearing capacity.With copper/steel composite material Alloy instead of Copper metal, be applied to production practices, can save a large amount of copper resources, obtain remarkable economic efficiency.
Usually adopt hot rolling and cold rolling composite algorithm to prepare copper-steel composite material in the prior art.
The hot rolling composite algorithm is with under HTHP, being rolled distortion by compound metal stock, and a kind of process of being heated and with the acting in conjunction of power different metal being combined has that technology is simple, the production efficiency advantages of higher.The compound complex method a kind of commonly used that combines as solid phase of hot rolling, its technical process generally comprised for 3 steps: at first carry out the cleaning of mating surface, comprise deoil, the deoxidation film.Make and treat that faying face keeps clean; Carry out then just combining, make the constituent element metal that common plastic deformation takes place through high temperature rolling, thereby make the contact surface of two constituent element metals reach the distance that atom is asked, and then form effective binding site, can form mechanical bond between the bimetallic this moment; Carry out diffusion heat treatments at last, be called thermal sintering again, in this process through the firm metallurgical binding of diffuseing to form of atom.The advantage of hot rolling composite algorithm is less demanding to milling train, is opened composite plate easily greatly, and shortcoming is a complex process, and thickness of product and bed thickness are difficult with control.
Be the production technology of main process cold rolling compound comprising " a cold rolling compound diffusion annealing under surface treatment one normal temperature ".Compare with the hot rolling composite algorithm, the first pass deformation of cold rolling compound tense is bigger, generally will reach 60-70%; Even higher, but cold rolling composite algorithm can realize the combination of multiple constituent element, and can produce coiled composite; Size is accurate, and efficient is high, is one of present most widely used method therefore.Though cold rolling composite algorithm promptly has been used for commercial production as far back as the fifties; But when the production that is used for copper/steel composite material, do not obtain desirable effect; Its reason is that the matrix and the oxide of copper and alloy thereof all has good plasticity; Cold rolling compound tense breach do not occur though blank reaches 70% its surface through brushing and first pass deformation yet, and the result is that blank is being worn breach and the steel compound (further increasing the restriction that first pass deformation receives mill capacity again) that thin oxide-film is squeezed into steel with original table; Therefore combine very fragility, bond strength is low and unstable.
Summary of the invention
The objective of the invention is to deficiency, a kind of production method of improved copper steel composite board is provided to copper steel composite board production method in the prior art.

The Zr of 6 ~ 8 weight portions, the Zn of 25 ~ 50 weight portions,
The Al of 5 ~ 30 weight portions, the Fe of 10 ~ 40 weight portions,
0.5 the Si of ~ 1 weight portion, the Mo of 0.4 ~ 0.8 weight portion
4) rolling
Under the situation that the combination aspect of steel plate, copper coin is relative; Under hydrogen and inert gas hybrid protection gas, be heated to 460 ~ 500 ℃; Wherein the volume content of hydrogen is 0.8 ~ 2%; Be incubated 5 ~ 7 minutes then, drafts be 10 ~ 15% situation through two roll continuous rollings, mill speed is selected in 5～15mm/s;
5) annealing
Clad steel plate after rolling is carried out annealing in process, and annealing temperature is 560 ~ 580 ℃, and temperature retention time is about 1.8 ~ 2 hours;
6) clad steel plate is carried out smooth, polishing.
For 1) the removing surface process steps, pickling can be removed the oxide layer of metal surface, and alkali cleaning can be removed the grease of metal surface; In addition; Wire brush can be cleared up remaining oxide skin, carries out alkali cleaning before use earlier, adds subsidiary grease in man-hour with further removal.
For 2) the texturing processing procedure, to steel plate and copper coin treat that composite surface carries out texturing and handles, suitable roughness helps the diffusion recombination process of complex metal layer in the following process.In addition, the abrasive band that granularity is big is used for steel plate, and the less abrasive band of granularity is used for copper coin.
For 3) spraying binder course step; Contain a large amount of Zn in the binder course; Because the direct associativity of copper and iron is relatively poor, and Zn and copper, steel all have good binding property respectively, so contain the binder course of a large amount of Zn in setting; In the operation of rolling, Zn spreads in copper coin, steel plate and promotes that steel plate combines with the effective of copper coin.
And the Zr element exists with copper zirconium disperse compound form in the copper steel alloy.The copper zirconium compounds of disperse forms dispersion-strengtherning in the copper steel composite board; And the copper zirconium is a high melting compound; When annealing, hinder the answer and the recrystallization process of copper matrix, thereby reduce consequent softening, so the adding of Zr element makes the steel plate copper coin combine more firmly effectively; Improve the anti-softening temperature and the tensile strength of composite, improved the heat endurance of alloy.
In addition, add an amount of Si and Mo in the binder course, can improve the anti-oxidant and stable of binder course.
For 4) rolling step, the present invention is through experiment, and mill speed is selected in 5～15mm/s scope, and the interfacial combined function of composite board is the highest.
For 5) annealing steps, temperature has decisive role to diffusion rate.Metal diffusion is very slow under the normal temperature, but (generally at fusing point more than 1/2) metal diffusion is very fast in the high-temperature region.To consider the different diffusion temperatures of two kinds of metals when metallic composite is heat-treated simultaneously, make thermal effectiveness reach optimum state.The heat treatment optimum temperature is that the theoretical annealing temperature with two kinds of metals serves as to confirm according to adding experiment again.Except that selecting the proper heat treatment temperature, temperature retention time is also very crucial.Temperature retention time is mainly definite through testing, and temperature retention time is directly related with thickness of diffusion layer, but the two not proportional relation.The present invention finds that through a large amount of experiments optimum annealing temperature is 560 ~ 580 ℃, and best temperature retention time is about 1.8 ~ 2 hours;
