Abstract
The invention discloses a high temperature resistant superconductive copper wire which is prepared by the following components comprising, by weight, 80-200 parts of copper, 30-80 parts of aluminum, 5-20 parts of cupric oxide, 1-5 parts of nickel, 10-15 parts of chromic oxide, 5-10 parts of magnesium, 1-10 parts of iron trioxide, 1-6 parts of manganese, and 2-10 parts of silver. The high temperature resistant superconductive copper wire provided by the invention has extremely high conductivity, and is safe and harmless; a preparation method of the copper wire is very simple, and the copper wire is especially suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of metal alloy, particularly, relate to a kind of high temperature resistant superconduction copper cash and preparation method thereof.
Background technology
The copper that needs the mass consumption high conductivity in the power transmission is mainly used in the power Shen.Line cable, omnibus bar, transformer, switch, interconnecting devices and unitor etc.In the transmission of electricity process of electric wire, owing to resistance heating wastes electric energy.Consider from energy-conservation and economic angle, promote " " best cross-section of cable " " standard at present in the world.The standard of pop over, merely from reducing the angle of one-step installation investment, in order to reduce the cross-section of cable as far as possible, with under the rated current of design requirements, unlikely appearance is dangerous overheated, determines the minimum permission size of cable.By the cable of this standard laying, though mounting cost is low; But in the life-time service process, the resistance energy consumption is bigger." " best cross-section of cable " " standard is then taken into account these two factors of one-step installation expense and power consumption, suitably amplifies cable dimension, to reach the purpose of energy-conservation and best overall economic efficiency.According to new standard, the cross-section of cable often adds than old standard and is twice abovely, can obtain the energy-saving effect about 50%.
In for some time, supply falls short of demand owing to steel, considers that the proportion of aluminium has only 30% of copper, once taked in wishing the aerial high-voltage power transmission line of weight reduction with the measure of aluminium for copper in the past in China.Consider from environment protection that at present aerial transmission line will transfer to and lay cables underground.In this case, aluminium is compared with copper, has the bigger shortcoming of poorly conductive and cable dimension, and proves definitely inferior.
Be used for large-capacity steam turbine generator rotor slot wedge, large-size machine conducting ring, electrode welder, mould of plastics and transfer mold
The Cu alloy material of directions such as tool should have high strength, high conduction, thermotolerance etc., over-all properties is had relatively high expectations, at present, main still the employing contains beryllium copper at home, but contain elements such as beryllium, cobalt in the beryllium copper, make that the production cost of material is very high, higher beryllium element can cause the pollution of environment and the harm of the person in the alloy production process.All seeking the substitute material of beraloy both at home and abroad, serial copper alloys such as CuNi2SiCr, CuNi9Sn3 been have successively have been researched and developed, the partial properties index of these materials has reached the berylliumbronze level, but still there is a big difference for integrated performance index, how to improve the over-all properties of berylliumbronze substitute material, be still the problem that the copper alloy field remains further research.
