Embodiment 1

[0028] Embodiment 1, a kind of aluminum alloy cable belt and production method thereof

[0029] 1. Product ingredients

[0030]

[0031] 2. Production method

[0032] (1) Melting Add scraps and remelted aluminum ingots that meet the above requirements into the flame reverberatory furnace, heat to melt and stir thoroughly, stirring for 15 minutes each time, and stirring again at intervals of 20 minutes to prevent local overheating of the melt, and then carry out slag removal ;Take samples when the temperature is adjusted to 750±5°C. When sampling, pay attention to stirring the melt thoroughly to ensure uniform composition. According to the results of pre-furnace analysis, adjustments are made in the melting furnace according to the proportion of alloy components. The additives added during adjustment, such as Fe agent, Al-Si ingots, etc., must meet the requirements of national standards. When the melt temperature is measured, the thermocouple thermometer should be placed i...

Abstract

The invention relates to an aluminum alloy cable strap material and a production method thereof. The aluminum alloy cable strap comprises the following components in percentage by weight: 0.60 to 0.80 percent of Si, 0.20 to 0.40 percent of Fe, less than or equal to 0.05 percent of Cu, less than or equal to 0.03 percent of Mn, less than or equal to 0.03 percent of Mg, 0.02 to 0.03 percent of Ti and the balance of Al and inevitable impurities. The production method comprises the following steps of: smelting, refining in a standing furnace, refining crystalline grains, online degassing, filtering, continuous casting rolling, cold rolling, foil rolling, slitting and annealing. The tensile strength of the aluminum alloy cable strap is 90 to 105MPa and the percentage elongation is more than or equal to 23 percent. When the aluminum alloy cable strap is compared with the traditional product, the tensile strength is reduced, the percentage elongation is improved and requirements of clients are met to a greater extent. The production process is simplified; annealing for one time is required in the production process; and the product with low tensile strength and high percentage elongation can be obtained without adding any process in the subsequent processing process. By the method, the production cost can be saved, and the production efficiency and the yield are improved. The method is easy to popularize and has obvious economic and social benefits.

Description

[0001] technical field [0002] The invention relates to an aluminum alloy material, in particular to an aluminum alloy cable belt and a production method thereof. Background technique [0003] At present, the cable belts produced in China mainly include 1060, 1145, and 8011 series aluminum alloy products. Since the cable belts produced by the 8011 series aluminum alloy have good surface quality and high elongation, there is a tendency to gradually replace the former two. However, the main components of 8011 series aluminum alloy are Si and Fe, and the content is generally Fe>Si. Due to the characteristics of Si and Fe and the influence of unavoidable impurities in them, the strength of the produced 8011 "O" state cable tape is relatively hard. , can not meet the requirements of customers (tensile strength 90~110MPa, elongation ≥ 20%); and the cable products produced by ordinary 8011 alloy, the strength is generally 105~115MPa, elongation ≥ 18%, if you want to reduce it ...
