Abstract
The invention relates to a method for producing an aluminum-steel composite board (belt), comprising the following steps of: raw material preprocessing, powder compounding and rolling, diffusing heat treatment, leveling, longitudinally shearing, polishing, packing and the like and is a novel method developed on the basis of borrowing ideas from other composite material production methods. Metal powder rolling is favorable for realizing both powder-powder compounding and powder-board compounding as well as single-side compounding and double-side compounding, and the thickness of a composite layer can be controlled randomly. No brittle iron aluminide is generated in the composite layer which can be processed through deformation. The thickness of the composite board is not limited. The aluminum-steel compounding in the process of metal powder rolling belongs to metallurgy atomic union. Therefore, aluminum-steel composite products produced with the method have the advantages of high combination strength, wide application range and more varieties.
Description
Technical field
The present invention relates to the production method of a kind of aluminum steel plate composition board (band).
Background technology
The production method of aluminum current steel composite material is generally blast+rolling compounding technology, hot rolling or cold rolling compounding technology 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 compounding technology can only be produced with conventional metallurgical technology is as matrix material.
Summary of the invention
The purpose of present technique is to overcome the defective of above-mentioned prior art, and a kind of production method of aluminum steel matrix material is provided, and promptly uses metal-powder rolling aluminium (aluminium alloy) to cover steel plate (band) technology and produces aluminum steel composition board (band).Aluminum steel composition board (band) is meant two metal plates (band) product that metallic aluminium (aluminium alloy) powder and steel plate (band) is synthesized two kinds of metals by rolling technique one.The performances such as physical strength of the existing steel of this product have the property of metallic aluminium (aluminium alloy) again.
For reaching above purpose, the present invention adopts a kind of new technology to produce aluminum steel composition board (band), adopts following production stage:
1, starting material pre-treatment.
---steel plate (band), aluminium (aluminium alloy) powder---is rolled pre-treatment to the composite rolling starting material.
2, powder composite rolling.
Steel plate (band) enters the powder milling train after operations such as uncoiling, leveling, guiding, correction.
Aluminium (aluminium alloy) powder enters the powder milling train through distributor.
Both carry out composite rolling.
In the operation of rolling, the increase of contact area is because the distortion of metallic surface jut causes, and then is the distortion simultaneously of matrix metal and protrusion of surface part subsequently.Along with constantly breaking of pure surface, crackle constantly broadens and is inserted matrix metal, reduced hardenability, 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.
By the atonic heat capacity diffusion process between the metal constituent element, make two metallographic phase mutual diffusion increase bonded area, to improve bonding strength.And make the metal of work hardening realize recovery and recrystallize, and eliminate unrelieved stress, improve plasticity, help further processing.
4, smooth.
Smooth effect following points:
(1) reaches the required thickness requirement of finished product.
(2) sealed porosity, the surface densification of realization matrix material.
(3) eliminate the yield point elongation that cold rolled strip annealing back exists, improve the cold rolled strip weave construction, regulate the mechanical property of cold rolled strip.
(4) improve the planeness of cold rolled strip.
(5) make the cold rolled strip surface have certain roughness.
5, slitting.
Its effect is band steel board or the band coil of strip that the band steel branch after smooth is cut to various width and substance.
6, polishing.
Require finished product is carried out in various degree polished finish according to difference.
7, packing.
Require finished product is packed according to difference.
Above-mentioned whole process flow as shown in Figure 1.
Above-mentioned metal-powder rolling goods mainly are plate and band.Its operation of rolling is that metal-powder is constantly carried powder to the gap of roll by distributor, by nip pressure it is compacted into successive base material.The base material by solidifying sintering and follow-up rolling and thermal 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 processing method of development.Metal-powder rolling both can realize that powder one powder was compound, can realize that also powder one 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 composition board is unrestricted.The aluminum steel of metal-powder rolling is compound to belong to metallurgical atom combination.So aluminum steel composite prod bonding strength height of this method production, 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.
