Abstract
The invention relates to a production and machining method, and particularly discloses a machining method for a thick-walled seamless red copper pipe. The machining method comprises the steps of casting, extrusion, rolling, drawing, inspection and packaging. According to the method, a process flow is short, the method is high in automation degree, and the produced red copper pipe is high in strength, high in purity, excellent in electrical conductivity, high in qualified rate, performance and quality and low in impurity content and oxygen content.
Description
Technical field
The present invention relates to a kind of production and processing method, especially a kind of processing method of heavy wall seamless copper tube.
Background technology
Along with expanding economy, market is increasing to the demand of copper.But in the face of limited copper resource, copper material waste is larger in process of production for the conduction copper rod using in power system in the past, the purity of copper material is lower, and electric conductivity is poor.For limited copper resource is reasonably utilized, in prior art, there is seamless copper pipe, copper material is saved in the production of seamless copper pipe more.Due to the restriction of production technology, the electric conductivity of the seamless copper pipe of prior art needs further to improve.
Summary of the invention
The present invention is intended to address the above problem, and a kind of processing method of heavy wall seamless copper tube is provided, and the copper tube purity produced by the method is high, electric conductivity is better, and its technical scheme adopting is as follows:
A processing method for heavy wall seamless copper tube, is characterized in that, the step of described production and processing method is followed successively by:
A) founding: be that more than 99.95% Cu-CATH-1 plate adds in foundry furnace by raw material, heating makes copper coin fusing by high-frequency electromagnetic, keeps charcoal to cover in casting process, adds phosphor-copper by proportioning; Carry out semi-continuous casting, prepare the copper base of Φ 162 × 600mm;
B) extruding: the copper tube billet of Φ 162 × 600mm is heated to 840 ± 5 ℃, prepares the copper tube billet of Φ 80 × 10.5mm on 24.5MN hydraulic press;
C) rolling: the copper tube billet of Φ 80 × 10.5mm is put into core print, push in four roller planetary rollings and be rolled, prepare the copper pipe of Φ 30 × 4mm, turn/min of mill speed 45, feed 4500mm/ time, in the operation of rolling, adjusts feed and mill speed to guarantee tubing non-trimming;
D) drawing: to the copper pipe rolling out head processed, then clamp with clamp, be drawn into the copper pipe of Φ 15 × 2.5mm in the empty machine drawing of 50t;
E) finishing: the copper pipe of drawing is aligned, repairs, cleaned on finishing machine;
F) check: whether product, it is qualified to check if being tested;
G) packing: product is packed on request.
Tool of the present invention has the following advantages: method technological process of the present invention is short, automaticity is high, the copper tube intensity produced is high, purity is high, electric conductivity is better, impurity content is low, oxygen content is low, qualification rate is high, is a kind of processing method of the heavy wall seamless copper tube of producing high-performance high-quality.
Accompanying drawing explanation
Fig. 1: processing process figure of the present invention;
The specific embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described:
As shown in Figure 1, a kind of processing method of heavy wall seamless copper tube, is characterized in that, the step of described production and processing method is followed successively by:
A) founding: be that more than 99.95% Cu-CATH-1 plate adds in foundry furnace by raw material, heating makes copper coin fusing by high-frequency electromagnetic, keeps charcoal to cover in casting process, adds phosphor-copper by proportioning; Carry out semi-continuous casting, prepare the copper base of Φ 162 × 600mm;
B) extruding: the copper tube billet of Φ 162 × 600mm is heated to 840 ± 5 ℃, prepares the copper tube billet of Φ 80 × 10.5mm on 24.5MN hydraulic press;
C) rolling: the copper tube billet of Φ 80 × 10.5mm is put into core print, push in four roller planetary rollings and be rolled, prepare the copper pipe of Φ 30 × 4mm, turn/min of mill speed 45, feed 4500mm/ time, in the operation of rolling, adjusts feed and mill speed to guarantee tubing non-trimming;
D) drawing: to the copper pipe rolling out head processed, then clamp with clamp, be drawn into the copper pipe of Φ 15 × 2.5mm in the empty machine drawing of 50t;
E) finishing: the copper pipe of drawing is aligned, repairs, cleaned on finishing machine;
F) check: whether product, it is qualified to check if being tested;
G) packing: product is packed on request.
With way of example, describe the present invention above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
