Abstract
Be problem such as solve copper pipe, the cost height of copper facing pipe, manufacturing efficiency is low, environmental pollution is big, the present invention realizes that a kind of is the novel metal pipe and the manufacture method of raw material with copper and bimetal copper-steel.The copper base-steel bi-metal pipe adopts copper strips to coat steel and makes through technologies such as rolling, volume type, solderings.Be applicable to the pipe of using of telescopic antenna sleeve pipe, condenser for refrigerator pipe and other purposes.The copper-clad-steel bimetallic tube cost is low, and copper material, economic benefit and obvious social benefit are polluted, saved in manufacturing efficiency height, minimizing.
Description
The invention belongs to novel metal pipe and manufacture method thereof in the metallurgic product.
Copper-clad-steel bimetallic tube is used for wireless telescopic antenna sleeve pipe, condenser for refrigerator pipe, decorates with pipe and other purposes pipe.
Common employed copper pipe has plenty of with the copper facing pipe and replaces.The cost of raw material height of copper pipe, processing productivity low, manufacturing efficiency is low.And the electroplating technology of copper facing pipe is big for environment pollution, the quality instability, and anti-corrosion performance is poor.
The objective of the invention is to realize a kind of bimetal tubing and manufacture method thereof with copper-clad steel in order to address the above problem.
Task of the present invention realizes as follows: make a kind ofly based on the steel layer, inside and outside tube wall is covered with the bimetal tube of copper layer, and its manufacture method is the copper strips that surface treatment is clean, be pressed into "
" type; coat to handle clean steel; being rolled into needs 1.5～2 times of pipe thickness; be cut into band and be rolled into tep reel, carry out cold rollingly after the pickling, be rolled to 0.75～1 times of required pipe thickness; carry out bright annealing; finish rolling becomes the thickness of required tube wall, carry out bright annealing again, then the pipe band that to become required tubing format diameter be width of the bimetallic strip slitting after the annealing.The both sides of base band rolling domatic overlap joint mouth, cans, cutting to length carry out soldering again, cool off, come out of the stove, align in soldering oven.
Advantage of the present invention is:
1, smooth, the cleaning of the outer wall surface of copper-clad-steel bimetallic tube, corrosion resisting property are good.
2, the intensity height of tubing, its technical performance index all reach and surpass the technical order of copper pipe and copper facing pipe, and its use value can replace copper pipe or copper facing pipe fully.
3, the raw material overall cost is low, productivity is high, and the manufacturing efficiency height is saved copper material, energy saving, reduces the pollution of environment.
4, the thickness of body inner and outer diameter dimensional accuracy and multiple copper layer is controlled constant product quality easily.
5, copper-clad-steel bimetallic tube can also be processed into single-walled pipe and double wall pipe, economic benefit and the obvious social benefit of different size.
Fig. 1 is a copper clad steel bimetal single-walled pipe viewgraph of cross-section of the present invention.
1 for covering the copper layer among the figure, and 2 is the steel layer, and 3 is sloping type overlap joint mouth.
Fig. 2 is a copper clad steel bimetal double wall pipe viewgraph of cross-section of the present invention.
Fig. 3 is a copper-clad-steel bimetallic tube manufacturing process diagrammatic sketch of the present invention.
One embodiment of the present of invention:
1, as shown in Figure 1: based on the steel layer, inside and outside wall is covered with the single-walled pipe of copper layer, or double wall pipe as shown in Figure 2.
2, its manufacture method is as shown in Figure 3:
(1) pickling, scratch brushing etc. in hydrochloric acid solution carry out surface treatment copper strips and steel.
(2) will handle clean copper strips be pressed into "
" heating of shape coating steel, when being 880～900 ℃, temperature carries out hot rolling.
(3) the copper clad steel bimetallic strip is rolled to needs 1.5～2 times of thickness of pipe wall, be curled into dish.
(4) carry out cold rollingly after pickling processes, be rolled to 0.75～1 times of required pipe thickness, produced in the bell-type furnace of hydrogen, nitrogen protective gas by ammonia decomposition device, temperature is 700～750 ℃ and carries out bright annealing.
(5) finish rolling becomes the thickness of required tubing wall, and the required thickness tolerance is ± 0.006 millimeter, and plate shape Roughness is no more than 0.25 millimeter in one meter.
(6) carry out bright annealing.By the width of required pipe diameter, slitting becomes the pipe band of copper clad steel bimetal single-walled pipe or double wall pipe again.
(7) be processed into 8～12 domatic soldering overlap joint mouths of spending in the both sides of pipe band.Be coated with lubricant oil.
(8) place plug and be curled into the individual layer or double-deck multiple copper base-steel bi-metal cast, cutting to length.
(9) pipe that is rolled into type is put into the soldering oven that is reducing atmosphere,, in 1120～1160 ℃ of temperature, carry out soldering with Elema heating.
(10) brazed tubes is cooled off in stove.When reducing to 80～100 ℃, temperature comes out of the stove aligning, integer, packing.
(11) through the copper-clad-steel bimetallic tube of lead welding and shaping, can also carry out drawing process again, be processed into the more copper-clad-steel bimetallic tube of minor diameter.
