Abstract

The invention discloses a special-shaped cast alloy copper bar production process which comprises the specific steps of casting, heating, extruding, finishing, pickling, checking, stretching, straightening, cleaning, finishing, checking, and warehousing. A red copper ingot is cast through melting by a melting furnace; the ingot is heated by a heating furnace; the heated ingot is transitionally extruded by an oil press, a supporting extrusion die and a supporting punching pin; the head and the tail of the red copper ingot are sewn by a piece of sawing equipment; the red copper ingot after finishing is pickled by a piece of pickling equipment; and the tension of a tensile product is straightened on a straightening machine in a tension straightening mode. A machining process including a transitional similar extrusion method, a transitional similar stretching method and a finished product stretching method is adopted. A copper bar produced by the process has good mechanical properties and high conductivity. The process is simple, easy to operate, and convenient to control. The production cost is reduced.

Description

Special-shaped casting alloy copper bar production technology
 
Technical field
The invention belongs to alloy copper bar production technology, be specifically related to a kind of special-shaped casting alloy copper bar production technology.
 
Background technology
The purposes of copper material in electric power, communications industry is very widely, it is saturated that common alloyed copper comes low-end market, but the main dependence on import of special-shaped alloy copper bar needed for power industry high-end market, because its all technical requires strict, and belong to non complete symmetry type copper material in special shape due to special-shaped casting alloy copper bar, production difficulty is large, mostly rely on from external import, but its good performance is significantly when current Chinese energy anxiety.The current special-shaped casting alloy copper bar of China belongs to non complete symmetry type copper material in special shape, and all technical requires strict, and production difficulty is large.Except having the requirement of superelevation to the conductance of material, particularity and the tolerance of shape also have strict demand.But want the index reaching each side also very difficult with existing technology.
 
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of special-shaped casting alloy copper bar production technology is provided, easy to operate.
Special-shaped casting alloy copper bar production technology provided by the invention, concrete steps are as follows: founding-heating-extruding-finishing-pickling-inspection-stretching-aligning-cleaning-finishing-inspection-warehouse-in.Adopt smelting furnace to carry out melting and casting and become red copper ingot blank, adopt heating furnace heating ingot blank, hydraulic press and supporting extrusion die and the pecker ingot blank to heating is adopted to carry out transitionality extruding, sawing device copper base is adopted to carry out sawing end to end, adopt pickler to carry out pickling to the copper base after finishing, adopt stretcher leveling mode to carry out stretcher leveling to elongated article on straightener; Adopt the processing technology of transitional similar type extrusion, transitional similar type pulling method and finished product pulling method.
Special-shaped casting alloy copper bar production technology provided by the invention, its beneficial effect is, the copper bar satisfactory mechanical property of production, and conductance is high, and technique is simple, is easy to operation, and operation is convenient to control, and reduces production cost.
 
Embodiment
Below in conjunction with an embodiment, special-shaped casting alloy copper bar production technology provided by the invention is described in detail.
 
Embodiment
Concrete steps are as follows: founding-heating-extruding-finishing-pickling-inspection-stretching-aligning-cleaning-finishing-inspection-warehouse-in.Adopt smelting furnace to carry out melting and casting and become red copper ingot blank, adopt heating furnace heating ingot blank, hydraulic press and supporting extrusion die and the pecker ingot blank to heating is adopted to carry out transitionality extruding, sawing device copper base is adopted to carry out sawing end to end, adopt pickler to carry out pickling to the copper base after finishing, adopt stretcher leveling mode to carry out stretcher leveling to elongated article on straightener; Adopt the processing technology of transitional similar type extrusion, transitional similar type pulling method and finished product pulling method.
