Abstract

The invention discloses Al-Fe-Mg-Zr aluminum alloy used for coal mine cables. The Al-Fe-Mg-Zr aluminum alloy comprises 0.2 percent-1.1 percent of Fe, 0.01 percent-0.4 percent of Mg, 0.001 percent-0.2 percent of Zr, 0 percent-0.1 percent of Si, 0 percent-0.2 percent of B and the balance being Al and impurities, wherein the resistivity of the aluminum alloy is not larger than 0.028164 omega*mm<2> / m, the elongation at break is not lower than 10 percent, and ninety-degree fatigue bending frequency is larger than or equal to thirty. The aluminum alloy material is smelted, cast and rolled, so that an aluminum alloy rod is obtained; afterwards, the aluminum alloy rod is subjected to pulling, bunch stranding and softening, so that an aluminum alloy cable core is formed; next, the cable core is subjected to extruded insulation, cabling, sheath extrusion or armoring, so that an aluminum alloy cable is manufactured. The manufactured aluminum alloy cable has the advantages of being high in strength, high in electric conductivity, good in bending performance and the like, and therefore the requirements for cable performance in the field of coal mines can be satisfied.

Description

technical field

[0001] The invention relates to the technical field of coal mine cables, in particular to an Al-Fe-Mg-Zr series aluminum alloy and an aluminum alloy cable for coal mine cables. Background technique

[0002] Due to the complex environment, harsh working conditions, frequent movement, and short service life of cables used in coal mines, the area where gas accumulates is very dangerous. Abrasion resistance and resistance to external tensile properties are very high. Therefore, cables for coal mines are products with high technical content in the cable industry.

[0003] Ordinary cables use copper core conductors. With the over-exploitation of copper resources, copper resources are becoming increasingly tense and on the verge of scarcity. Therefore, it is necessary to use other materials to replace copper core conductors to meet market demand. Among metal materials, aluminum has the characteristics of good electrical conductivity, light weight, and low price. I...
