Specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

A kind of production technology of the long length high-strength high-conductivity copper-chromium-zirconium contact line in the present embodiment, it includes following work Skill step：

Step one, non-vacuum melting

Carried out to standard cathode copper, copper chromium intermediate alloy and copper zirconium intermediate alloy is delivered in non-vacuum melting device in proportion The melting of Cu-Cr-Zr alloy；

The structure of the non-vacuum melting device is as shown in figure 1, it includes all-in-one oven 1, the second body stove 2 and the 3rd body stove 3, interface channel 4 is provided between the second body stove 2 and the 3rd body stove 3, the middle part of the interface channel 4 is provided with graphite wolf's fang From even device 5, the graphite mace is from the outside of interface channel 4 of the both sides of even device 5 around being equipped with hot-wire coil 6 for rod；

The top of the all-in-one oven 1 is provided with loading channel 7, the loading channel 7 and is provided with feeding device 8, described The front end of all-in-one oven 1 is provided with cover plate 9；

The all-in-one oven 1, the second body stove 2 and the top of the 3rd body stove 3 are provided with argon gas import 10 and pressure regulator 11；

The second body stove 2 and the top of the 3rd body stove 3 are provided with the carbon mouthful 12 that phosphorates；

The top of the 3rd body stove 3 is provided with upper lead conticaster, and the crystallizer 13 of the upper lead conticaster stretches into the 3rd body In stove 3；

In all-in-one oven, after feeding device adds material, the space above stove liquid（Argon gas room）It is interior full of argon gas, keep air pressure In 1.02 pressure-fireds of standard atmospheric pressure, if it exceeds 1.02 standard atmospheric pressures, pressure regulator is automatically releasable gas and adjusts automatically Section, if air pressure is less than 1.02 pressure-fireds of standard atmospheric pressure, automatic inflating device applying argon gas, by the technology, can make stove water with Air exclusion, and zirconium does not react with inert gas argon gas, so as to ensure that chromium does not react with zirconium with extraneous gas.Together When can also will be attached to aqueous vapor on copper coin and other gases blowout argon gas room.In copper coin is added completely into all-in-one oven When, close cover plate.

In 3rd body stove, phosphorate carbon mouthful can plus good phosphorus piece and wooden carbon after close, the purpose of the carbon that phosphorates makes in furnace gas Foreign gas can fully react, and reach deoxygenation, the purpose of dehydrogenation.In second body stove, it is similar to.The function phase of pressure regulator is same.

This step is in further innovation and the improvement of the basis of existing three bodies stove, because all-in-one oven and the second body stove pass through After electromagnetic agitation, internal alloy composition distribution is still uneven, showing the characteristics of not only disperse but also gather, the alloy of a part The concentration of composition is high, is distributed in jujube core shape many places, and the concentration of a part of alloying component is low, as shown in Figure 2；Cause this jujube core formula The reason for distribution is the i.e. metal bond energy in stove liquid between the metal cation of solvent because the viscosity of alloying furnace liquid solvent is big Height, the resistance of the diffusion of alloy elements of addition is big, and alloying element is not easy uniform diffusion, just as adding sesame in oil, though So by stirring, but still can not uniformly spread, it is different from soluble in water uniformly the diffusion like that of sodium chloride and forms the molten of stabilization Liquid.For solve the problems, such as alloying element uniformly spread, using stove water by the second body stove and the 3rd body stove interface channel when, increasing Plus the vortex that hot-wire coil is produced is sufficiently stirred for, and by graphite mace from even device when, because graphite mace is from even Under multiple spines effect on device, the alloying element stove water of jujube core formula can be broken and redistribute, and make addition alloying element equal Homogenize.

Step 2, continuous up-casting

Cu-Cr-Zr alloy is prepared using Continuous Up casting mode and continuously casts bar；

Step 3, on-line continuous solution strengthening

Using on-line continuous solution strengthening device between 960 ~ 1000 DEG C on-line continuous solution strengthening 0.5 ~ 2 hour, so Room temperature is cooled to using on-line continuous granulating unit afterwards；

As shown in figure 3, the on-line continuous solution strengthening device includes the first outer cylinder body 14, in first outer cylinder body 14 Bell-type electromagnetic heater 15 is provided with wall, first outer cylinder body 14 is provided centrally with the first rotation steel cylinder 16, described The upper and lower part of one outer cylinder body 14 is respectively arranged with the discharging opening 18 of first charging aperture 17 and first；

The top of first outer cylinder body 14 is additionally provided with argon gas import 10 and pressure regulator 11；

Cu-Cr-Zr alloy is continuously cast bar and is wound on the first rotation steel cylinder from after first charging aperture entrance, after solution strengthening again From the first discharging opening out；

The application uses bell-type electromagnetic heater, and unsuitable electricity consumption hinders heating, because resistance wire can not contact copper bar, Rubbed with the copper alloy bar on the steel cylinder of rotation, resistance wire can be damaged, heat transfer can only be carried out by gas, and as guarantor The argon gas heat transfer property for protecting gas is extremely low, so that heating effect extreme difference；

During another advantage of bell-type electromagnetic heater is heat treatment process, temperature can be controlled in certain limit, But because the heat conduction of air is stronger, cross-ventilation can be formed, so as to cause heat skewness, so as to cause to be heated element Heating is uneven, so that it is uneven to be heated component temperature（Although copper alloy is the good conductor of heat, this non-uniform temperature Phenomenon still protrude）, and the surrounding that device heating can be in heating element heater is utilized, along with the copper alloy on steel cylinder casts bar Do not stopping rotation, copper alloy bar can be made uniformly to heat；

Make protection gas additionally, due to using argon gas, because the thermal conductivity of argon gas is low, can greatly reduce due to gas The heat skewness weighing apparatus phenomenon that convection current is produced, so as to improve the uniformity of element heating；

The method that the copper bar of whole disk is carried out resistance heating by this device contrast tradition in a fixed manner, with greatly excellent Gesture.

As shown in figure 4, the on-line continuous granulating unit include the second outer cylinder body 19, the top of the second outer cylinder body 19 and Bottom is respectively arranged with delivery port 21 and water inlet 20, and water-cooling circulating system 22 is provided with outside second outer cylinder body 19, The water-cooling circulating system 22 is connected with water inlet 20 and delivery port 21 respectively by pipeline, in second outer cylinder body 19 Portion is provided with upper and lower two mesh plates 25, and upper and lower two mesh plates 25 are located between water inlet 20 and delivery port 21, described The second rotation steel cylinder 26 is provided between upper and lower two mesh plates 25, second charging aperture 23 is provided with second outer cylinder body 19 With the second discharging opening 24, the discharging opening 24 of the second charging aperture 23 and second is located between upper and lower two mesh plates 25, and described the Two charging apertures 23 are located at the top of the second discharging opening 24；

Continuous uniform water cooling, if not using mesh form, middle current can be more very fast than the water velocity at edge, so Copper bar water cooling will be formed uneven, so that there is larger difference in copper alloy internal organizational structure, if adopting mesh-structured water Cooling, middle water velocity is not in laminar flow phenomenon, so as to reach the effect of continuous uniform water cooling, so that copper alloy Dry uniform cooling so that copper copper chromium zirconium inside group even structure.
