Abstract

The invention discloses a wire conductor for heat treatment equipment and a production process thereof. The wire conductor for heat treatment equipment comprises multiple base wires made of an aluminum alloy, and the aluminum alloy contains 0.46 to 0.95 wt% of Si, 0.22 to 0.65 wt% of Mg, 0.05 to 0.15 wt% of rare earth and the rest being aluminum; the wire conductor has a tensile strength of 200 to 320 Mpa, an elongation at break of 8 to 35%, a ratio of endurance to tensile strength of 0.8 to 1.2, and a work hardening index of 0.03 to 0.15. According to the wire conductor production process, an aluminum alloy base wire is manufactured through solid solution and wire drawing, and then, through twisting, compression, aging heat treatment and annealing steps, the wire conductor is obtained. The wire conductor uses the aluminum alloy as a main component, due to addition of various metal elements and rare earth in a reasonable proportion, the temperature resistance, the tensile strength, the elongation at break and the impact resistance are significantly improved, and a wire conductor for heat treatment equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a wire conductor used for heat treatment equipment and a production process thereof. Background technique [0002] As the global temperature rises and air pollution becomes more and more serious, the country's regulations on the discharge of waste gas and wastewater are becoming more and more stringent, and the development of energy saving, emission reduction and lightweight development has become very urgent. At present, the wire conductors used for heat treatment equipment basically use copper conductor wires, but copper conductor wires are heavier in the same cross-section, and copper resources in my country are relatively scarce. [0003] In recent years, especially in the field of electric wires used in heat treatment equipment, attention has been paid to aluminum conductors, and aluminum having a specific gravity about one-third that of copper is used as a conductor for the p...
