Below in the embodiment of the preparation method of the compound ingot bar of penetration type silver-bearing copper, and the compound ingot bar of silver-bearing copper based on preparation
The preparation method of band is further provided for, is specifically comprised the following steps：
(1) the compound ingot bar being made of using the splicing of the method for penetration type silver-bearing copper dissimilar metal
After copper bar, silver bar and copper frame is prepared, the copper bar of half, silver bar and copper frame are deoiled and surface burnishing part
Then two kinds of different raw material of processing mode are fabricated to composite billet by reason, the other half copper bar respectively without surface treatment
Material, the i.e. compound ingot bar of penetration type silver-bearing copper.
(2) it is 70% cold combined processing to carry out deflection to above-mentioned compound ingot bar using four-roller roller group solid-phase composite rolling mill
(rolling) forms penetration type silver-bearing copper side and answers band；The latter made product of materials statement surface treatment is bonded in operation of rolling median surface,
The product not being surface-treated cracks in operation of rolling median surface.Surface treatment can significantly improve the bond strength of product.
(3) the latter made product of (2) step Central Plains material surface processing is rolled, rolling side answers band and exists
Diffusion annealing is handled under protective atmosphere；
In the present embodiment, 750 DEG C of annealing temperature, protective gas is hydrogen (air pressure is more than atmospheric pressure in stove), and throughput is
0.4~0.6m3/ h, annealing time are 4 hours.
(4) material strip is answered into the side after diffusion annealing and carries out four-pass rolling on four-roller reversable cold-rolling machine, in the present embodiment,
12%, total deformation controls between 50% every time deformation amount controlling.
(5) soft annealing that the band after (4) step is processed carries out controlled atmosphere is handled, it is desirable that annealing temperature 600
DEG C, atmosphere is hydrogen (air pressure is more than atmospheric pressure in stove), and throughput is 0.4~0.6m3/ h, annealing time are 4 hours.
(6) band after the completion of (5) step is finished on four-roller reversing finishing mill, final thickness is
0.1mm does not leak copper, and properties meet drawing requirement by material strip is examined by cubing.
The utility model is effectively reduced opening for product by using improved four-roller solid-phase composite rolling mill roll system
The deviation with silver layer is split, improves production efficiency.Because four-roller solid-phase composite rolling mill roll system forms material certain squeeze
Pressure and position-limiting action increase the interface cohesion of material, reduce the side extension of material, greatly improve the lumber recovery of product；
Conventional technique is compared simultaneously, is produced using four-roller solid-phase composite rolling mill roll system, the product of substance bigger can be produced,
Improve production efficiency.
In the prior art without using four-roller solid-phase composite rolling mill roll system roll, material during deformation, due to
Material upper surface is different with the transverse spreading of lower surface so that and staggered floor occurs for positioning silver layer, meanwhile, the energy that equipment applies material
Amount part can be consumed by the extension of width direction, it is not easy to effective molecule is formed in interface and is combined, leads to bond strength
It is deteriorated.
Therefore, the above-mentioned improved four-roller solid-phase composite rolling mill roll system of the utility model, the effective material that solves are opened
The deviation with silver layer is split, greatly improves production efficiency.
In summary embodiment, the preparation for carrying out answering band in penetration type silver-bearing copper side using the utility model, can effectively subtract
Phenomena such as few band cracking and silver layer deviation, while the bond strength of copper silver in material strip is obviously improved, shorten production week
Phase greatly improves production efficiency.
In the utility model foregoing description, it is to be understood that term " on ", " under ", "front", "rear", etc. instructions
Orientation or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of the utility model and simplify description,
Rather than instruction or imply signified device or element must have specific orientation, with specific azimuth configuration and operation, because
This is it is not intended that limitation to the utility model.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
