Abstract
The present invention provides a kind of production methods of bus duct conducting copper, comprising the following steps: goes out ingot casting using existing semi-continuous casting apparatus for casting, sawing is copper slab ingot；Copper slab ingot is heated using walking beam furnace；Clean impurity, the oxide skin of copper flat bloom surface with water；Copper slab ingot after heated carries out hot rolling in one group of pass series and deforms to obtain hot rolling base；Copper sheet base carries out surface sand-blasting process or pickling；Hot rolling blank after cleaning with water carries out cold rolling on milling train；It aligned, saw side, oil removing, obtain finished product；The present invention provides a kind of production method of bus duct conducting copper, obtained bus duct conducting copper eliminates the coarse grain of inside ingot, improves the defects of inside ingot is loose, and copper bar density reaches 8.87-8.9g/cm3(at a temperature of 20 DEG C), Tensile strength reaches 36-46kg/mm2, conductivity 97-101%IACS improves the service life of copper bar so that electrisity consumption be made to decline.
Description
Technical field
The invention belongs to field of electrical equipment, more particularly, to a kind of production method of bus duct conducting copper.
Background technique
Bus duct because have safe and reliable, capacity is big, small in size, the design and construction period is short, series matching, be convenient to mount and dismount,
The advantages that long service life, is suitable for the power supply of the places such as megastore, exhibition center, gymnasium, airport and skyscraper and uses；Mesh
The conventional machining process of preceding domestic production bus duct conducting copper are as follows: horizontal continuous-casting-slab sawing head-drawing-
Inspection-packaging；Horizontal continuous casting blank internal organizational structure is cast sturcture, coarse grains, granularity unevenness.The crystal grain of metal is big
It is small to influence whether its processing performance and service performance, it will lead to whens coarse grains that structure is not fine and close, and metal strength is low, plasticity is poor.
Also depositing again inside horizontal continuous casting billet has the defects of loose, stomata, not high consistency, and cast sturcture's bring defect eventually results in
The density of special-shaped conducting copper is only and tensile strength is lower, and service performance reduces.
Summary of the invention
In view of the problems of the above-mentioned prior art, the technical solution adopted by the present invention to solve the technical problems is to propose
A kind of production method of bus duct conducting copper, comprising the following steps:
(1) after electrolytic copper dissolves in electric furnace, go out ingot casting using existing semi-continuous casting apparatus for casting, sawing is copper slab ingot；
(2) copper slab ingot is heated using walking beam furnace；
(3) impurity, the oxide skin of copper flat bloom surface are cleaned with water；
(4) the copper slab ingot after heated carries out hot rolling deformation in one group of pass series, first existsMilling train
Five passages of upper rolling, Zhi Hou3 passages are rolled on milling train, finally obtain hot rolling base, and hot rolling general working rate reaches ε
=90%；
(5) copper sheet base is cut into, surface sand-blasting process or pickling are carried out, removes newly generated oxide skin during the rolling process
And impurity；Surface part burr, overlap are repaired simultaneously；
(6) hot rolling blank after cleaning with water is existedCold rolling is carried out on milling train；
(7) it aligned, saw side, oil removing, obtain finished product.
Preferably, in the semi-continuous casting step copper slab ingot saw size be 123-132 × 232-243 ×
1560mm。
Preferably, using 11 roller straighteners, copper bar template aligning is carried out.
Compared with prior art, beneficial effects of the present invention are as follows: the present invention provides a kind of bus duct conducting coppers
Production method, obtained bus duct conducting copper eliminate the coarse grain of inside ingot, and it is loose equal scarce to improve inside ingot
It falls into, copper bar density reaches 8.87-8.9g/cm3(at a temperature of 20 DEG C), Tensile strength reaches 36-46kg/mm2, conductivity 97-
101%IACS improves the service life of copper bar so that electrisity consumption be made to decline.
