Description
Technical field
The present invention relates to Copper making technical field, specifically a kind of copper cash base and its production method.
Background technology
It is generally acknowledged that copper content is higher in copper cash base, copper cash base quality is better.Traditional smelting process is by Pb in copper liquid
It is down to less than 0.015%, Cu and purifies to more than 99.90%.But copper content it is higher when quality is not so good sometimes on the contrary.Due to copper
The next procedure of line base be for making cable, therefore copper cash base can drawing diameter and resistivity be quality judge mark
It is accurate.The element that resistivity is influenceed in copper cash base and the element of influence drawing are have studied based on this 2 point present invention, by trying repeatedly
Test, eventually find and add aborning some elements copper cash base is made into alloyed copper wire base, matter copper cash base is favorably improved on the contrary
Amount.The present invention was not only reduced except the time used by lead, and greatly reduced smelting expense, while also ensure that copper cash base
Product quality.
The content of the invention
In view of this, the present invention is intended to provide a kind of copper cash base.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：A kind of copper cash base, including following weight hundred

Matter.
Further, the chemical constituent of following percentage by weight is included：Copper 99.75~99.85%, lead 0.05~
0.07%th, surplus is other metallic elements and inevitable impurity.
Further, the chemical constituent of following percentage by weight is included：Copper 99.84%, lead 0.06568%, surplus are it
Its metallic element and inevitable impurity.
Further, a diameter of 7.98~8.05mm of the copper cash base.
Further, the elongation of the copper cash base is 37~42%.
Further, the resistivity of the copper cash base is 0.01703~0.01716.
Further, other metallic elements include arsenic, antimony, bismuth, iron, tin, nickel, zinc, sulphur, phosphorus, selenium or tellurium in one kind or
It is a variety of.
The invention solves the problems that another technical problem be：The production method of above-mentioned copper cash base is provided.
The production method of above-mentioned copper cash base, comprises the following steps：
(1) Copper making is obtained into copper liquid；
(2) content of the copper and lead in the step (1) in copper liquid is examined；
(3) if the content of lead is less than lower limit in copper liquid, lead is added into smelting furnace, the content of lead is met above-mentioned want
Ask；If the content of lead is more than higher limit in copper liquid, copper liquid is purified, the content of lead is met above-mentioned requirements；
(4) satisfactory copper liquid in the step (3) is even pricked into unit through copper bar continuous casting and is rolled into copper cash base.
Further, the step (1) is smelted using copper scap as raw material using reverberatory furnace.
Further, the step (1) is using cathode copper as raw material, using shaft furnace melting.
Relative to prior art, the present invention has the advantage that：
(1) copper 99.7~99.9% in copper cash base of the present invention, lead 0.05~0.08%, follow-up use that can meet copper bar will
Ask；
(2) copper cash base of the present invention for diameter 7.98~8.05mm copper cash base can meet National Electrical copper cash base T3 mark
Standard, most thin drawing can be to 0.195mm filaments；
