Embodiment 1

[0014] Eight tons of aluminum ingots (99.7%) are selected, and the impurity content (except silicon, iron, and copper) does not exceed 0.02% by weight, and they are melted in a circular aluminum melting furnace, and 0.045 to 0.15% by weight of zirconium, 0.02 -0.12% copper, 0.2-0.95% iron, and 0.05-0.4% rare earth as alloying elements. The alloying temperature is 730-760°C, after homogenization and stirring, refining and degassing, the refining temperature of the aluminum alloy liquid is 730-760°C, slagging and slag removal, covering the surface of the aluminum alloy liquid with a solid covering agent, and standing for 35-45 Minutes; rapid analysis of the chemical composition before the furnace, monitoring and adjustment of the element content, the aluminum alloy liquid that meets the requirements passes through the launder, the continuous degassing furnace (the temperature of the aluminum alloy liquid in the continuous degassing furnace is 700-760 ° C), aluminum slag Filter b...

Abstract

A method for producing high-intensity heat-resistant aluminum alloy line belongs to production technology field of materials applied to electrical engineering. It winnows component and content of alloy and controls technology to produce high-intensity aluminum alloy line. Select zirconium, copper, iron, silicon and rare earth with different percent of weigh and aluminum ingot into stove. The impurity content of aluminum ingot does not exceed 0.02%(besides silicon, iron, copper). Add alloying additive element and whisk, fine, component fast analyzing before entering stove. Put into continuous caster to produce aluminum alloy pole and draw into aluminum alloy line after tempered heat treatment and cooling to get production. In this method, the capability of production is satisfied the overhead designed demand for Three Gorges to serve the construct of transporting electrical power from west to east.

Description

technical field [0001] The invention belongs to the technical field of manufacturing electrical materials, specifically a manufacturing technology of high-strength heat-resistant aluminum alloy round wire. Background technique [0002] At present, the domestic technical level of manufacturing high-strength heat-resistant aluminum alloy round wire (taking a diameter of 4.2mm as an example), its mechanical and electrical performance indicators are: electrical conductivity not less than 55.0% IACS, tensile strength not less than 225MPa, this high The tensile strength of high-strength heat-resistant aluminum alloy wire cannot meet the design and use requirements of large-span power transmission and transformation lines in my country. The design requirements for the large spans of several Three Gorges crossing rivers and rivers under construction are: electrical conductivity not less than 53.0% IACS, tensile strength not less than 265MPa (taking diameter 4....
