Description
Technical field
The present invention relates to a kind of working method of composite metal plate, particularly a kind of metal-powder and metal sheet composite rolling method.
Background technology
Different metallographic phase is compound to be to have utilized the characteristic that different metal had, with they compound be one, become the novel material more excellent than single metallicity.In each field of national economy, some abominable work condition environments of existence in various degree all, often single metal is difficult to be competent at, and causes its life-span short, causes very big financial loss.Metallic substance is constituted infringement, as atomospheric corrosion, oceanic climate and sea-water corrosion, the corrosion of chemicals, the infringement of high temperature oxidation, pyrochemistry corrosion, the corrosion of water and soda acid salt; Also useful single metal strength is on the low side, wear resistance deviation or weight are bigger than normal etc. do not meet working condition requirement or the like.At these different working conditions, the metallic substance of selecting superior performance just can reach raising intensity with routine with metallographic phase is compound as surface layer, improves wear resistance, reduces corrosion and improves purposes such as life-span.The manufacturing technology of matrix material and matrix material is the focus and the cutting edge technology of research in the our times scope.
At present, the manufacture method of complex plate strip mainly contains four kinds, below compound with aluminium and steel plate band be that example is illustrated:
1.1 or immersion
Hot dip aluminum plating be with the hot dipping of steel plate band in aluminium liquid, make the steel plate belt surface adhere to thickness 40-150 μ m metal aluminum or aluminum alloy; Hot dip aluminum plating the aluminum layer thickness of its surface recombination of aluminum steel matrix material be restricted, the composite layer of aluminum thickness of disposable thermal immersion plating is no more than 150 μ m, if technology is not strict, pin hole appears in surface easily, water wave, bubble, floating, situation such as slag, trachoma influences its erosion resistance, therefore must increase hole-sealing technology.This technology easily produces frangible compounds, and is unfavorable to deformation process.This technology has pollution to environment, and can only produce the strip product of thickness below 4.0 millimeters.
1.2 hot cementation process
This technology is that steel (iron) workpiece is buried with the penetration enhancer that contains aluminium powder, makes aluminium infiltrate steel piece surface through the long period at a certain temperature; Hot aluminising makes the aluminum steel composite material surface compound between friable metal occur, influence mechanical performance of products, hot aluminising workpiece extexine aluminum content generally is not more than 30%, the workpiece of not redeformation after the only suitable steel casting of this processing method or ironcasting and the aluminising, inapplicable deformable material.This explained hereafter efficient is low, the cost height.
1.3 explosion cladding process
Explosion cladding process comprises the compound and blast+rolling compound two kinds of methods of single blast.This technology is by blast or blast+rolling compound with metallic aluminium or aluminum alloy strip and steel plate (band).This technology can only spiral-plate production, and production efficiency is low, and at every turn can only single face compound.The surface recombination layer thickness is thicker, and general composite bed thickness is not less than 1.5 millimeters, the cost height.Its thickness of compound sheet material is not suitable for producing thin strip composite wood generally greater than 6 millimeters.
1.4 strip cold rolling mills or hot rolling are compound
Cold rolling and hot rolling is compound to be that two kinds of strips are combined with each other by rolling, only is applicable to the production of thin plate band, is unsuitable for the production of plate of moderate thickness band.
Need to prove that compound and the cold rolling or hot rolling of blast is compound can only produce matrix material with conventional aluminum or aluminum alloy strip of producing, and for the composite bed particular requirement and the aluminium alloy that routine can not be produced just can't be produced.
