Description
The invention belongs to the clad metal sheet field of making in the rigidity structural detail.Mainly be applicable to the manufacturing composite metal plate, be specially adapted to make continuously coiled composite metal.
Composite metal plate as the composite plate that normal carbon steel plate and corrosion resistant plate, copper coin or titanium plate are composited, has obtained using comparatively widely.The application of composite metal plate is mainly based on economy and economizing on resources.For example, require to possess the pressure vessel of resistance to corrosion, more suitable with the manufacturing of employing stainless steel, but the cost height; Composite plate that get is made this class pressure vessel if employing common straightcarbon steel and stainless steel are compound, and the thickness of corrosion resistant plate only is 2～10% of integral thickness, like this, has not only kept the corrosion resistance of container, and has reduced cost widely.In addition, it is more rare resembling the expensive material heat-resisting, corrosion-resistant and that can conduct electricity of copper, nickel and chromium and so on, if use bilayer and 3-layer composite material, then can help to save resource.
The manufacture method of existing composite metal plate mainly contains two kinds: the one, and it is compound to explode; The one, hot rolling is compound.
Exploding compound is that basal plate is placed on the smooth firm work anvil, normally on the cement plate, complex laminate is placed on the top of basal plate with certain angle, explosive is placed on the complex laminate top, in order to prevent that thin complex laminate from damaging, usually between explosive and complex laminate, fill up the buffer board of last layer metal or other material.Pass through explosive charge, produce one extremely strong impulsive force, make complex laminate produce extremely strong angular impact to basal plate, the interface that makes two plates of the energy foot of this collision produces metallurgical the connection, promptly the interface of two plates reaches interatomic combination, reaches the composite with certain shear strength.The compound advantage of exploding is to prepare difform composite, as compound slab, compound end socket, multiple tube or the like.
Hot rolling compound normally earlier with the composite surface of basal plate and complex laminate with suitable straight of machine-tooled method processing, keep clean; And the face that will process is superimposed relatively, and welded perimeter vacuumizes then, seals the interface of two plates again, prevents to treat the surface oxidation of composite surface; After the sealing, the two superimposed plate that is superimposed sent in the heating furnace heat, after waiting to be incubated certain hour, carry out hot rolling, rolling roll-force (depressing power) and amount of pressure can be determined according to the thickness of basal plate, complex laminate and final composite plate; After the hot rolling, superimposed plates promptly becomes required composite plate composite.
The manufacture method of above-mentioned two kinds of composite plates all exists some common shortcomings and shortcoming separately:
(1) above-mentioned two kinds of complex methods all can not serialization production, can only single-piece production, and production efficiency is very low.
(2) the compound area of their composite is restricted, and is only limited to the area of individual composite or composite elements, so production cost is also high.
(3) the compound influence factor of blast is a lot, the selection of angle during as the model of explosive and quantity, complex laminate and basal plate and basal plate placement and spacing, padded coaming etc.
Therefore, be difficult to expect the influence of (or prediction) each factor, therefore, also be difficult to standardization control explosion cladding process, promptly be difficult to produce greatly.
