Abstract
The invention relates to a production method of a copper coated steel plate (strip). The production method comprises the following steps of: raw material pre-processing, powder composite rolling, diffusing heat treatment, cold rolling, annealing, smoothing, slitting, surface treatment, packaging and the like, and the method provided by the invention is a new process method developed based on the adsorption of other production process methods of composite materials. According to the invention, metal powder rolling can be used for not only realizing powder-powder compounding, but also realize powder-plate compounding, one-side compounding and two-sided compounding, and the thickness of a composite layer can be freely controlled; and the composite layer cannot produce brittleness materials and can be fully subjected to deformation processing, the thickness of the composite plate is not limited, and the copper coated steel combination rolled by metal powder belongs to metallurgical atom combination, thus the copper coated steel plate (strip) produced by the method has the advantages of high bonding strength, wide application range and various varieties.
Description
Technical field
The present invention relates to the production method that a kind of copper covers steel plate (band).
Background technology
The production method of aluminum current steel composite material is generally blast+rolling complex technique, hot rolling or cold rolling complex technique etc.Wherein, blast+rolling complex method can only the compound spiral-plate of production binary single face, can not produce the strip volume of two-sided compound and polynary compound thickness less than 4mm; And hot rolling or cold rolling complex method can only be produced strip.
It must be noted that the strip that above complex technique can only be produced with conventional metallurgical technology is as composite.
Summary of the invention
The purpose of present technique is to overcome the defective of above-mentioned prior art, and the production method that provides a kind of copper to cover steel is promptly covered the technological production of copper of steel plate (band) with metal-powder rolling copper and covered steel plate (band).Copper covers steel plate (band) and is meant bimetallic plates (band) product that metallic copper powder and steel plate (band) is synthesized two kinds of metals through rolling technique one.The performances such as mechanical strength of the existing steel of this product have the property of metallic copper again.
For reaching above purpose, the present invention adopts a kind of new technology to produce aluminum steel composite plate (band), adopts following production stage:
1, raw material pre-treatment.
To composite rolling with raw material-steel plate (band), copper powders may---be rolled pre-treatment.
2, powder composite rolling.
Steel plate (band) gets into the powder milling train after operations such as uncoiling, leveling, guiding, correction.
Copper powders may gets into the powder milling train through distributing device.
Both carry out composite rolling.
In the operation of rolling, the increase of contact area is because the distortion of metal surface jut causes, and then is the distortion simultaneously of parent metal and protrusion of surface part subsequently.Along with constantly breaking of pure surface; Crackle constantly broadens and is inserted parent metal, has reduced hardenability, and two kinds of intermetallic spaces are more and more littler; The oxygen of the inside has been used up soon; Therefore pure surface has been retained, and has formed weldering nuclear along with breaking of pure surface, and bonding region is constantly expanded.Simultaneously, because under the effect of pressure, rolling up of crackle caused vacuum at intermetallic, the pure surface of metal can directly be contacted, thereby metal is combined with each other.
3, diffusion heat treatments.
Through the atomic heat diffusion process between the metal constituent element, make two metal phase counterdiffusion increase bonded area, to improve bond strength.And make the metal of work hardening realize recovery and crystallization again, and eliminate residual stress, improve plasticity, help further processing.
4, cold rolling.
Breaking down copper is covered steel plate (band) be rolling to the finished product required thickness.
5, annealing.
Make finished product reach desired mechanical property.
6, smooth.
Smooth effect following points:
(1) reaches the required thickness requirement of finished product.
(2) sealed porosity, the surface densification of realization composite.
(3) eliminate the yield point elongation that cold-strip steel annealing back exists, improve the cold-strip steel institutional framework, regulate the mechanical property of cold-strip steel.
(4) improve the glacing flatness of cold-strip steel.
(5) make the cold-strip steel surface have certain roughness.
7, slitting.
Its effect is band steel board or the band coil of strip that is cut to the band steel branch after smooth various width and substance.
8, surface treatment.
By demands of different to finished surface polish, wire drawing etc. is final handles.
9, packing.
According to demands of different finished product is packed.
Above-mentioned whole process flow is following:
Above-mentioned metal-powder rolling goods mainly are plate and band.Its operation of rolling is that metal dust is constantly carried powder to the gap of roll by distributing device, through nip pressure it is compacted into continuous base material.The base material through solidifying sintering and follow-up rolling and heat treatment, obtains qualified goods again.It follows rolling front and back powder quality invariance principle.
In sum, the present invention is on other process for producing composite material method basis of absorption and the new process of development.Metal-powder rolling both can realize that powder-powder was compound, can realize that also powder-plate is compound; Can single face compound, also can be two-sided compound; The thickness of composite bed can arbitrarily be controlled.Composite bed does not produce the short iron aluminide, fully can deformation processing.The thickness of composite plate is unrestricted.The aluminum steel of metal-powder rolling is compound to be belonged to metallurgical atom and combines.Therefore the aluminum steel joint product bond strength of this method production is high, applied widely, wide in variety.
The exploitation of metal-powder rolling Study on Technology for adopting the product that conventional production technology can not be produced or production cost is high at present, has been found out a new production outlet.Domestic blank has been filled up in the appearance of this technology, for the development of enterprise with new vitality is provided transition.
The specific embodiment
The present invention foundes the production method that a kind of new copper covers steel plate (band), promptly uses metal-powder rolling copper powder+steel plate (band) method production of copper to cover the steel plate band, adopts following production stage:
1, raw material pre-treatment.
(1) with the steel strip surface descaling machine to the matrix steel band eliminate rust, degreasing, oil removing, texturing handle.
(2) raw material complex copper powder is carried out classification, proportioning, annealing, dried.
2, powder composite rolling.
(1) steel band by the uncoiler uncoiling after, through operations such as leveling, guiding, corrections, make the matrix steel band steadily get into distributing device and powder milling train by uncoiler.
(2) with distributing device factors such as the flow of complex copper powder, cloth evenness, composite bed thickness are controlled.
(3) breaking down composite band gets into winder behind transfer.
3, diffusion heat treatments.
Select different heat treating regimes for use according to different steel bands and copper powders may material, the breaking down composite band is carried out diffusion heat treatments.
4, cold rolling.
Breaking down copper is covered steel plate (band) be rolling to the finished product required thickness.
5, annealing.
Make finished product reach desired mechanical property.
6, smooth.
According to the requirement of different product, the composite band after selecting for use rational flattening process to diffusion heat treatments is carried out smooth processing.
7, slitting.
According to demands of different, be cut to the band steel branch after smooth the band steel board or the band coil of strip of various width and substance.
8, surface treatment.
By demands of different to finished surface polish, wire drawing etc. is final handles.
9, packing.
According to demands of different finished product is packed.
