Before the aluminum coil is rolled, some pretreatment sections are required to ensure that the surface of the aluminum coil is clean. Lest there is residual grease and smoothing agent on the surface, which will affect the painting and application. Therefore, the aluminum coil should be pre-treated in the following aspects before forming.

In the process of making aluminum coil, in order to help change its shape, we need to heat it at high temperature. In the state of high temperature, it will be softer, and its shape is easier to change. After the shape is adjusted, its temperature can be reduced to maintain a certain hardness. Aluminum coil will have some curling problems, what is the reason?

At present, the amount of aluminum coil in China has been gradually increasing, and it is already a very important part of the aluminum industry. Aluminum coil has the characteristics of low density, long service life and beautiful appearance, and is an indispensable product for pipeline insulation in power plants and chemical plants. In order to make better use of aluminum coil and extend the service life of aluminum coil, there are also strict requirements for the storage environment of aluminum coil.

Aluminum coil is a metal product for flying shear by casting and rolling machine after calendering and drawing Angle processing. Aluminum coil is an important component in the production of various industrial, commercial and consumer products. Air conditioning, automobiles, aircraft, furniture, structural parts and many other products can be involved in the use of aluminum coil. The wound aluminum sheet is easier to store and transport than many stacked boards.

Honeycomb panel is a new type of high strength environmental protection building composite material developed according to the bionics principle of honeycomb structure The reason why it is called honeycomb board is because it is a plate made of honeycomb core for the base.The honeycomb aluminum plate is a metal composite plate product series developed by combining the composite honeycomb panel technology of the aviation industry.Honeycomb sandwich structure is adopted, which is a composite plate made of high strength alloy aluminum plate coated with decorative coating with excellent weather resistance as the surface, bottom plate and aluminum honeycomb core through high temperature and high pressure. This plate will greatly enhance the structural integrity of the original aluminum plate, so that it is not easy to bend, the scale can be larger, and the flatness will be better.

Galvanized aluminum and magnesium steel plate is an alloy-coated plate among coated steel products. The mass fraction of metal elements in the coating is: 53% aluminum, 43% zinc, 2% magnesium, 1.5% silicon and other elements. The surface of the galvanized magnesium steel plate has a fine zinc flower texture formed by crystallization. The neatly arranged fine zinc flowers make the appearance of the coated product more natural and delicate. Galvanized aluminum and magnesium steel plate is a new type of highly corrosion-resistant coated steel plate. Its coating composition is mainly zinc, which is composed of zinc plus 1.5%-11% aluminum, 1.5%-3% magnesium and trace amounts of silicon (different manufacturers have proportions slightly different).

Aluminized steel plate is a steel plate plated with a layer of pure aluminum or an aluminum-silicon alloy containing 5% to 10% silicon on the surface of carbon steel. Aluminum plating methods include: hot plating, electrophoresis and vacuum evaporation, among which hot plating is the most widely used. Aluminized steel plates have good resistance to high-temperature oxidation and will not discolor for a long time at 450°C. The maximum use temperature can reach 750°C. It also has good resistance to atmospheric corrosion, especially corrosion resistance to SO2, H2S, CO2 and other gases. The corrosion resistance is 3 to 6 times that of galvanized steel plates. It is mainly used in automobile exhaust systems, heat-resistant appliances, beverage cans, etc.

Aluminum tube as a kind of high-strength duralumin, can be strengthened by heat treatment, in annealing, hardening and hot state of plasticity medium, spot welding weldability is good, with gas welding and argon arc welding aluminum tube has a tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve the corrosion resistance. Can also be used as a mold material.

More Detail

Aluminum tubes have the characteristics of corrosion resistance and light weight, and are widely used in all walks of life, such as: cars, ships, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home furnishing, etc. Aluminum tubes are now everywhere in our lives.
