It equipped with 1600mm color coating machine, grinder, travelling crane, pure water facility, sewage treatment facility, and exhausted gas incinerator etc. Products in this process now are wildly used in various industries of national economic construction.
Rolling Line
Sheet and strip line in SWA is composed of hot rolling line, cold rolling line and sheet line and qualified ISO9001:2000 Quality Certification System. This line can produce aluminum and aluminum alloy sheet and strip.
Mill Line
Hot rolling line: It’s put into production on 1st Jan, 1970, revamped in 1990. All aluminum and aluminum alloy sheets and strip which dimension as following: 1XXX to 8XXX series, thickness is from 2.0 to 200mm and width is from 800 to 2500mm can be produced in this line. It is the largest aluminum hot rolling equipment in china at present. Major equipments of mill line include Φ750/Φ1400×2800mm fourfold reversible hot rolling mill, Φ650/Φ1400×2800mm quaternary reversible hot rolling mill, 3 sets of ingots flat grinders, one set of acid and alkali washing machine, pusher furnace and 3 sets of radial double rifling chain electric heating furnace.
Cold rolling line:It’s put into production in Oct 1970 and revamped several times, produces cold rolling sheets and strips in strip way. This line mainly rolls the hot rolling products in normal temperature and provides the high quality cold rolling sheets for the later manufacturing process. The products, which thickness is from 0.1 to 7.0mm and width is from 800 to 2500mm, are adapted to various industries and widely used in civil use and military use from general to high end. Cold rolling line is equipped with a Φ650/Φ1400×2800mm fourfold reversible cold rolling mill and a Φ360/Φ1000×1400mm fourfold irreversible cold rolling mill.
Shear Line
It’s starting up on 1st July, 1970, revamped in 1980 and 2002. Dimension of strips as following can be sheared in this line: thickness is from 0.5 to 10.0mm; width is from 1000 from 2500 mm. and the max shear length could reach to 12,000mm (cut accuracy is ±2mm). The 1850mm thick dimension aluminum sheet shear line self-developed by SWA can provide the aluminum and its alloy sheets which thickness is from 1.0 to 5.0mm, width is from 800 to 1700mm and length is from 1000 to 6000 mm online filming and paper packaging process. The line is equipped with 2800 mm pre-shear line, 1830 mm cross cut shear and the 1850 thick dimension shear.
Sheet Final Finishing Line
It’s equipped with 2800mm calendar, 400-ton stretcher, cleaning machine, precision saw, soft sheet machine and hard sheet machine. This line was put into production on 1st July, 1970, aluminum alloy anneal sheets and quenching sheets which thickness is from 0.5 to 12.0mm could be straightened, stretched, length sheared, cleaned in this line.
Heat Treating Furnace
put into production on 1st July, 1970, revamped in 2003, mainly used for annealing, quenching and aging in sheet manufacturing processes as well as for the finished coils annealing.
Major equipments: box type annealing furnace, sheet and coil annealing furnace, salt bath furnace, aging furnace.
Withdrawal Strengthening Line
imported from U.S.A in 1988, adapt to stretch, straighten, clean the coils which thickness is from 0.15 to 2.0mm and width is from 600 to 1640mm.
Major Equipment: 1640mm continuous stretch bending straightening machine.
Gas Cushioned Continuous Heat Treat Line
imported from U.S.A in 1988, the only gas cushioned continuous heat treat line for aluminum alloy sheet and strip in domestic aluminum fabrication industry. At present, it can produce 2xxxx series quenching aluminum strips which thickness is from 0.3 to 1.0mm and width is from 1000 to 1400mm, 6xxx series quenching aluminum strips which thickness is in 2.0mm and width is 1500mm, annealing aluminum strips which thickness is from 0.5 to 3.18mm and width is from 900 to 1600mm.
