Nannan Aluminum is the first to be equipped with the world's widest hard alloy sheet heat treatment production line

According to the bulk non-ferrous net reprint: At present, the development and production of the domestic aluminum-alloy body panel (Body-in-White) is still in its infancy, and there is still a big gap from abroad. Then, in addition to the production process technology and experience, the hot plate production line at the hot spot, air-cushion continuous heat treatment production line is also very important.

Air-cushion continuous heat treatment furnace, referred to as "air-cushion furnace", is an essential heat treatment equipment for aluminum alloy automobile plate production.

South South Aluminium introduced Austria 2800mm air-cushion continuous heat treatment production line with continuous annealing, solid solution, air-cooled quenching, water-cooled quenching, tension and straightening, cleaning, trimming, pre-aging, passivation, electrostatic coating and other functions to meet aviation Aerospace and automotive industry demand for a variety of high quality, high value-added aluminum alloy sheet products. It is the first to be equipped with a 2800mm air-cushion continuous heat treatment line that can produce the world's widest 2650mm hard alloy sheet.

Compared with the traditional box furnace, the air-cushion continuous heat treatment production line has unparalleled advantages, mainly reflected in:

(1) The entire heat treatment process can be carried out continuously, the heat treatment time is short, the production efficiency is high, and the degree of automation is high;

(2) A variety of heat treatment processes such as annealing, solution quenching and pre-ageing can be realized, with wide adjustable range and high temperature control accuracy;

(3) It can achieve uniform structure, good formability, small anisotropy, excellent mechanical properties, and is higher than the conventional index by more than 10%. The homogeneity of each index is within 5%.
