Abstract
The invention relates to a production technique, particularly to a copper alloy strip production technique which is a horizontal continuous casting-high precision cold rolling method. The production technique sequentially comprises the steps of material preparation, horizontal continuous casting, surface milling, cold rolling and cogging, annealing, finish rolling, washing, straightening, shearing, coiling, annealing of finished products and packaging. The production technique used for producing high-quality copper alloy strips has the advantages of short technological process, high yield, low energy consumption, small construction investment, short construction cycle and the like.
Description
Technical field
The present invention relates to a kind of producing and manufacturing technique, especially a kind of processing method of production of copper alloy sheet strip, i.e. horizontal casting-High Precision Cold method.
Background technology
The copper material demand of China just increases with annual 15%～20% speed, and this being increased in is resource consumption to a great extent.The best outlet that solves this predicament is to adopt less without skiver's technique, and active research exploitation copper material new variety, improve constantly quality product and be and meet the national economic development, reduce high-precision copper material import, strengthen the important measures of competitiveness in international market.And the semicontinuous casting-hot rolling of traditional production of copper strip-high finish rolling method technical process complexity, yield rate is low, energy consumption is large, environmental pollution is serious.
Summary of the invention
The present invention is intended to address the above problem, and a kind of processing method of production of copper alloy sheet strip is provided, i.e. horizontal casting-High Precision Cold method, and its technical scheme adopting is as follows:
A processing method for production of copper alloy sheet strip, horizontal casting-High Precision Cold method, is characterized in that, its step is followed successively by:
A) batching: more than 99.95% high-purity negative electrode no-oxygen copper plate and the alloying element that will add carry out proportioning by a certain percentage;
B) horizontal casting: adopt high-frequency electromagnetic heating to make copper coin fusing, keep charcoal to cover in castingprocesses, add in proportion alloying element; Cast continuously, prepare Copper Alloy Blank;
C) milling face: the oxide compound that mills Copper Alloy Blank surface with milling cutter;
D) cold rolling cogging: the blank of a upper operation is rolled with duo mill;
E) annealing: the work in-process of a upper operation are sent in the annealing furnace of nitrogen protection and annealed, annealing temperature 150-250 ℃, is incubated 15 minutes;
F) finish rolling: the plate after annealing is carried out to high precision rolling with duo mill and go out certain thickness copper alloy plate strip;
G) clean: copper alloy plate strip is cleaned with clean-out system;
H) aligning: the copper alloy plate strip after cleaning is aligned;
I) batch rolling: by curling copper alloy plate strip rolling;
J) finished products: the copper alloy plate strip of rolling is sent in the annealing furnace of nitrogen protection and annealed, annealing temperature 100-150 ℃, is incubated 30 minutes;
K) packing.
Tool of the present invention has the following advantages: the advantages such as technical process is short, lumber recovery is high, less energy consumption, construction investment is few, the construction period is short that it has are a kind of processing methodes of producing high-quality a large amount copper alloy plate strip.
Accompanying drawing explanation
Fig. 1 is production technological process of the present invention.
