A production process of 8011-o cable belt

Abstract

The invention relates to an 8011-O cable belt production craft in the cable belt field. The 8011-O cable belt production craft utilizes two strips of steel belts to assist cooling and meanwhile cancels an intermediate annealing procedure but utilizes finished product one-time annealing. The 8011-O cable belt production craft can not only produce products which meet requirements, but also effectively improve production efficiency and reduce production cost.

Description

【Technical field】 [0001] The invention relates to the field of cable tapes, in particular to a production process for producing 8011-O cable tapes. 【Background technique】 [0002] It is well known that the cable tape is an aluminum tape product used to wrap the appearance of the communication cable for protection and shielding; at present, the domestically produced cable tapes are mainly made of 1060, 1145 and 8011 series aluminum alloys, among which, Because the 8011-O cable belt produced by the 8011 series aluminum alloy is lighter in weight and has better protective shielding effect, the 8011-O cable belt has gradually replaced the 1060 and 1145 aluminum alloy cable belt; The thickness is 0.1-0.2mm, the tensile strength is 80-110MPa, and the elongation is above 20%. This aluminum strip is made of 8011 grade deformed aluminum alloy. , cover the surface of the aluminum strip with a plastic film, then cut it into several strips according to the required length, and roll the...

Problems solved by technology

[0003] However, since the 8011-O cable strips produced today are usually produced by hot-rolled billets or cast-rolled billets, although the cable strips produced by hot-rolled billets have the advantages of good elongation and moderate tensile strength, their manufacturing costs are relatively high. High, while the cable belt produced by casting and rolling blanks has a low manufacturing cost, but because the cooling rate is too fast when the casting and rolling method is used to produce the blank, there is a large internal stress and composition segregation in the slab, which leads to the cable belt. The strength increases obviously, and generally reaches 110-120MPa. At this time, in order to meet the strength requirements, it is basically to adopt secondary annealing, or increase the annealing temperature and increase the annealing time to reduce the product strength, but this will not only prolong the production of the product correspondingly. cycle, and it is very likely to cause coarse grains or orange peel inside the cable tape, which will lead to a decrease in product yield and an increase in production costs
