Abstract
The invention discloses a method for thermally treating an aluminum alloy cable. A cable material consists of the following components in percentage by weight: 0.01-0.3 percent of Cu, 0.01-0.6 percent of Mn, 0.02-0.5 percent of Sb, 0.01-0.2 percent of Ni, 0.001-0.2 percent of Ce and the balance of aluminum and inevitable impurities. The thermal treatment method is implemented by the following steps of: (1) pulling an alloy into a wire rod of 3-15 millimeters; (2) making the wire rod uniformly pass through a thermal treatment furnace by using a traction device, and thermally treating under the protection of nitrogen atmosphere at the temperature 523-618 DEG C for 2-3 hours; and (3) after the temperature of the thermally-treated cable wire rod is lowered below 60 DEG C, treating in an oil bath, and coating an insulating layer. The cable has high electric conductivity, heat conductivity and corrosion resistance.
Description
Technical field
The present invention relates to a kind of cable, specifically is a kind of heat treatment method of aluminium alloy cable.
Background technology
Wires and cables industry conduct and the closely-related one type of important industrial production of national economy, the application in the national economic development is more and more wider, and improve day by day the status, when bringing huge interests to the mankind, has also buried huge hidden danger to the mankind.Along with popularizing of electric power, when human mental muscle power had obtained great liberation, human normal life is increasing to have received electric restriction.And electric wire in the application of electric power transfer because technology and other reasons inevitably exist energy loss or the like problem; Human when paying close attention to electric wire; Principle for problem has had certain understanding, and also there has been certain understanding the while to the development of electric power transfer.
China is in 50～seventies of last century, and copper is as strategic resource, and the state basic policy of electrical applications aspect is exactly " with an aluminium for copper ", and copper cable can not use in civil buildings, and employed cable conductor is electrician's fine aluminium conductor mostly; To the mid-80; Aluminium conductor cable problem in use comes out; Especially the oxidation of aluminum conductor joint causes a lot of fire etc. that rise; And copper, aluminium price difference were little at that time, and copper conductor is in the superiority of aspect of performance such as electric, mechanical, durable in addition, and it is main on using, becoming gradually with copper; To 90 later years, multinomial national standard, standard also require in civil buildings, to adopt copper cable, and aluminium conductor is basic just not to have been adopted.But recent years, particularly since 2005, the copper metal price ascensional range of international market is very big.Since 2005, copper increased to 9000 dollars/ton, the economic crisis in 2008 years from 2000 dollars/ton; The copper valency is fallen from 9000 dollars/ton get back to 3000 dollars/ton; Yet 2009, the copper valency increased to 8000 dollars/ton from 3000 dollars/ton again, in by the end of December, 2010; The international copper valency records high again, and copper valency per ton is above 9500 dollars.The pressure that expands along with national currency in recent years increases suddenly, and the copper valency also has strong up-trend, and copper product shared cost in copper cable reaches more than 70%, and the price of copper cable is also being risen at the sound, thereby causes user's input cost significantly to increase.In the face of constantly soaring copper valency, and following unpredictalbe upward price trend, many clients begin to select cheap aluminium cable.Because aluminium is very high at natural content, the price of aluminum current material is equivalent to about 1/3rd of copper.Not only aspect raw material supply, there is advantage, at manufacture view, the cable of a same length, required aluminium important also lighter than copper generally can light 30-50%, therefore, in whole transportation and installation process, has also brought the effect of energy-conserving and environment-protective for the client.See with the existing market situation, become inevitable choice again for copper with " aluminium ".
Because existing electrician's fine aluminium cable be prone to produce oxidation, corrosion, thereby cause problems such as joint is on fire, need a kind of novel aluminum conductor of Application Research, improve the reliability of aluminium cable to solve this type of problem.
As alloy, be particularly useful for cable, it is because doped chemical need further improve its conductivity and mechanical performance through Overheating Treatment, and the heat treatment method of prior art is single, and alloy is different, and its heat treatment method is also different.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of performance more to be superior to the cable material of fine aluminium, this cable high strength, and be difficult for oxidation, corrosion.
A kind of aluminium alloy cable and processing method thereof that the present invention is prepared comprise the component of following weight:
Cu 0.01-0.3％
Mn 0.01-0.6％
Sb 0.02-0.5％
Ni 0.01-0.2％
Ce 0.001-0.2％
Surplus is aluminium and unavoidable impurities, and heat treatment realizes through following steps: (1) pulls into alloy in the wire rod of 3-15mm;
(2) make above-mentioned wire rod evenly through heat-treatment furnace through draw-gear then, heat treatment is the nitrogen atmosphere protection, and temperature is 523 ℃-618 ℃, and the time is 2-3h;
(3) after heat treatment cable wire is when temperature is reduced to below 60 ℃, through coated insulation layer after the oil bath.
Useful technique effect of the present invention is: at first, make treatment temperature lower through heat treatment for the wire rod after stretching, and energy-conservation, help homogenizing of element simultaneously, improve conductance; And at a certain temperature through oil bath, help soaking into, improve Corrosion Protection; Os through trace adds, and helps being homogenizing, improves lattice energy, improves conductance.
