The specific embodiment
The specific embodiment below in conjunction with embodiment is described in further detail foregoing of the present invention again:
A kind of continuous production technology of novel high-precision section copper strip may further comprise the steps:
A, melting: selecting copper for use is main raw material(s), selects for use natural crystalline flake graphite to carry out oxygen barrier and covers, and carries out melting then, and the copper alloy temperature is controlled in 1080 ℃ ± 10 ℃ the scope during melting, makes copper alloy; For satisfying the performance of high power device, copper is the copper material of elite composition or is the copper material of TFe 0.1 (KFC) for the copper alloy trade mark.Further improve a kind of novel elite composition copper material alloy of this process using of conductance of material, the copper material of described elite composition, its composition is by mass percentage: Cu:97～98%, Sn:0.05～0.20%, Fe:0.01～0.05%, surplus is an impurity.The copper material of this elite composition is better with respect to TFe0.1, and because of having removed P (phosphorus), conductance reaches 92%IACS, and intensity is 350～400Mpa, and the hot mastication point reaches 420 degrees centigrade.
B, on draw copper bar continuous casting: the copper alloy of melting among the step a is adopted draws copper bar continuous cast method and be cast as the copper alloy copper bar that diameter is the same diameter of Φ 16mm, and the take-up of copper alloy copper bar is discoid, the hauling speed of copper alloy copper bar is controlled at 0.5～0.55m/min; The weight of every dish plate-like copper bar is 2600～3400kg, preferred 3000Kg, and living again to produce for the big volume of serialization ensures that the finished product of all different sizes all is the copper bar with same diameter in the technology, has not only reduced cost and has improved production efficiency again.
C, continuously extruded: the copper alloy copper bar among the step b is sent in the extruder, carry out continuously extruded by the mould in the extruder to copper alloy copper bar, be the continuous band embryo of beveled rectangle (as shown in Figure 2) in the little extruding of 700 ℃ hot conditions for cross section, water-cooled is to the bright state in the income drum then; This is shaped as technological requirement and sets different gradients, and the requirement that explained hereafter is not only satisfied in this cross section has reduced the loss of mould again.
D, cogging: with the ratio of the continuous band embryo among the step c according to the featheredge and the webbing of the thickness of product specification designing requirement, grinding goes out the pass of the corresponding degree of depth on roll, ratio until featheredge that is rolled into the next process requirement and webbing makes continuous band.
E, the annealing of strong convection formula: continuous band in the steps d is put into the well vacuum stove carry out annealing in process, send into the protective gas that keeps temperature unanimity in the well vacuum stove for the uniformity that guarantees material adopts blower fan; The temperature of annealing in process is 500～600 ℃, and annealing time is 4 hours, annealing back insulation 2 hours; Protective gas is a carbon dioxide.
F, continuously gradient is rolling: gradient control and the mode of the light reduction rolling back of carrying out continuous multi-pass of the continuous band after strong convection formula annealing in process among the step e by breaker roll taken in the drum, made the copper strips that is web-like; The gradient scope is at 1～3 °; This operation is the committed step that guarantees material high accuracy size in the whole technology, because frame material has high gauge requirement, and tolerance ± 0.01, existing domestic material is owing to the restriction of equipment, and the material of production goes out to reach requirement at thin copper.
G, expansion continuous bright annealing: electronic material requires very strict to the fineness on surface, traditional annealing way is because the cross section particularity of special-shaped band is easy to generate scratch, so adopt the expansion bright annealing, the copper strips that is web-like among the step f is unreeled by unreeling machine on one side, be that the high temperature furnace of 20m is annealed by length then, and by the outlet water seal carry out anti-oxidation processing, and then carry out rolling once more by the winder of another side, be equipped with the protection paper tape that improves the quality of products during rolling between the copper strips, inject protective gas during annealing; The temperature of annealing in process is 800～1050 ℃, and the linear velocity of unreeling machine and winder is 5～20m/min, and protective gas is a nitrogen hydrogen.
H, finishing are rolling: for precision and the roughness that guarantees material adopts hard alloy roll to be rolled the copper strips of handling through the expansion continuous bright annealing in the step g.
The limit is cut in j, location: frame material requires very high to the linear symmetric degree of section copper strip, and traditional limit of cutting can't be satisfied and wanted ball, adopts the accurate roller of three-point fix formula to cut the copper strips after rolling positions the arrow limit and handles through finishing among the step h; Described three-point fix formula is meant when cutting the limit location, thick copper place with copper strips, locatees at the beginning of being chosen in the first two point of some fine positionings of roller scissors and roller scissors during the location.
K, degreasing passivation: adopt the ultrasonic wave oil removing to carry out ungrease treatment to the copper strips of cutting behind the limit through the location among the step j, coat copper protective agent on the surface of copper strips then and carry out Passivation Treatment;
L, packing warehouse-in.
