Why do I need to clean the coil?

In the cold rolling process of aluminum coil, because of the friction and rolling between the roll and the surface of the aluminum plate, the surface of the fine aluminum oxide powder will fall off and adsorption, rolling oil and its accompanying suspended components will remain on the surface of the aluminum coil, resulting in adverse effects on the composite aluminum coil, coating and other finished products processing. During the stretching and straightening process, due to the severe bending deformation of the strip on the roll, part of the tension exerted on the strip is converted into the pressure of the strip on the tension roll, and finally the friction force is formed to drive the roll set. If the surface of the alumina roll is not cleaned, the alumina powder falls off when it is deformed, and the oil is attached to the roll surface of the tension roll together, so that the roll surface is worn and the aluminum plate is slightly injured, so it must be cleaned by a special cleaning device.

Alumina coil

Aluminum coil cleaning is to use pressure pump to pressure the cleaning medium, non-contact spray washing or contact brushing on the strip surface, so that the aluminum powder oil on the surface of the material dissolves and falls off into the cleaning medium, and then dry by extrusion roll and high-pressure air purge, and even high temperature air drying, in order to obtain clean and dry aluminum coil. At the same time, through the continuous supplement of cleaning medium and online circulation filtration system used at the same time, so that the cleaning medium to maintain sufficient and clean, and greatly save the heat energy and cleaning medium. At present, the commonly used cleaning medium of the stretching and bending straightener in the aluminum coil processing industry is cleaning agent (or solvent oil), softening hot water and chemical solvent. Foshan Andli provides aluminum coil cleaning, passivation, anodizing, wire drawing and other surface treatment processing.

How do those aluminum sheets bend?

The bending of the aluminum plate, according to the state of the aluminum plate in accordance with the full hard, half hard, soft state to carry out the difference, usually the soft state is the key refers to the aluminum plate O state, the actual effect of the hard bending is basically not very line, in the aluminum plate state in general H18, H19, H38 are all hard, half hard state of the aluminum plate is usually able to fold, H24 is half hard.

Measures to prevent oxidative corrosion of aluminium coil

After the arrival of aluminum rolls, it is suggested to consider the temperature difference, air, and other reasons before making the disposal decision. For example, if the temperature difference between the two places is large, it is recommended to open the package within three days after the arrival of goods. In this way, aluminum coil surface corrosion caused by day and night or air can be avoided.

Different forms of aluminium - aluminium rods

Aluminum rod formation is about three steps, batching, melting, casting. According to the production needs, calculate and match different alloy components and various raw materials; Then put the good material into the smelting furnace to melt; Then the refined liquid aluminum is forged into different forms of aluminum rods.
