Description
Technical field
The present invention relates to the copper strips technological method for processing, especially a kind of copper steel is laminated with uses the copper strips technological method for processing.
Background technology
At present; It is a kind of product that steel and copper are laminated with that copper steel is laminated with band; Copper steel is laminated with the characteristics that material has merged two kinds of metals; Having advantages such as rotproofness, mouldability, extensibility, electric conductivity, weldability and the color of non-ferrous metal be attractive in appearance, also possess the good intensity of carbon steel, is the splendid product of instead of copper carrying material.This material is the substitute of the nonferrous materials of part industry use at present, and material cost can reduce by 50%.Copper steel is laminated with material, because of intensity is high, indeformable, excellent conductivity, can strengthen the arc extinguishing ability, has effectively improved the combination property of electrical equipment and decorative product.It is the performance that adopts copper, the price of steel that copper steel is laminated with band, so very by the market approval, the market copper steel is laminated with is with demand bigger.And that copper steel is laminated with in the band used copper strips is very high to performance, surface, template and quality of edges requirement; Tensile strength, hardness and grain size all exceed common copper alloy national standard scope; Therefore, copper steel is laminated with the production difficulty of copper strips very big, and production technology is difficult to control and stable.
The general soft attitude national standard of H65 brass band is tensile strength Rm>=290N/mm
2Percentage elongation A11.3>=40%; Hardness HV≤90; No grain size requirement.Copper steel is laminated with copper strips very high to performance, surface and quality of edges requirement, and tensile strength, hardness and grain size all exceed the national standard scope, tensile strength Rm≤270N/mm
2Grain size>=0.05mm; Percentage elongation A11.3>=30%; Hardness HV≤65 will reach this performance, production process be difficult to control, particularly finished product annealing process and annealing way difficulty grope because material is soft partially, must control template well, otherwise shearing is prone to cause copper strip surface to occur creasing, shearing can't be carried out.Copper strip surface requires tighter, will be rolled after copper strips and steel are laminated with, and finally makes copper strips thickness roll 0.02mm, like copper strip surface any defective is arranged, and copper steel is laminated with the back operation of rolling copper strip surface bleed-out will occur, makes copper steel be laminated with band and scraps.
