Automotive Aluminum Plates Technology and Equipment

Jun 14, 2016

Automotive aluminum production core technology is in a continuous annealing heat treatment and surface treatment, furnace, hot rolling mill, coiling machine, cold rolling mill and continuous heat treatment furnace air cushion. Modern production line of a hot rolling mill generally comprises a reversible breakdown mill and a finishing mill followed by high-speed, single-stand cold rolling mill is usually reversible. Melting, hot rolling and cold rolling process no significant difference with conventional aluminum production process, so the appropriate equipment without special requirements.

Continuous annealing process selected air furnace equipment including decoiler, degreasing tank, oven, district heating, district cooling, coiling machines, static and dynamic airflow furnace like matted strip propped up the board, while achieving heating or cooling. Aluminum plate floating in the furnace stable at a certain height uses the speed of the airflow to ensure high-speed aluminum plate heat exchanger. By controlling the speed of the aluminum plate in the furnace, the furnace temperature furnace suffered tension and pressure to achieve the solution treatment of the aluminum plate.

Air furnace hot zone furnace temperature accuracy of overseas high-level solution treatment can be controlled to ± 1.5 , the corresponding sheet temperature at ± 2 , while domestic air furnace temperature control accuracy of ± 3 . Currently Chinese manufacturers of equipment can not meet the production of automotive sheet required precision, the entire automotive sheet production line equipment to be imported.

Most of the domestic automobile industry, aluminum plate production companies do not have the background and related technology base, still in imitation stage abroad, the theoretical mechanism and technically at a disadvantage. But most of the domestic aluminum manufacturers and domestic brands of car manufacturers have a good basis for cooperation, the price also has certain advantages, but workable, it can be tailored according to the actual needs of automobile manufacturers.
Whether from the demand of the national strategic level, or the strength of domestic manufacturers of technology, the automotive the aluminum plate volume applications are no doubt. Domestic market demand is amazing, which is the foreign-related enterprises entered reason. In order to meet the needs of automotive lightweight, it will evolve many alternative materials, including aluminum long-term challenge is a strong opponent of steel. Aluminum large number of applications is limited by raw materials and manufacturing costs are high, the industrial structure, recovery and management factors, along with the development of technologies that will limit the breakthrough.
