Embossed Aluminum Coil Widely Used

The embossed aluminum roll is the rolling mill after rolling and is pulled at the time of processing for the flying shear of metal products. Aluminum is widely used in electronics, embossed aluminum roll packaging, construction, machinery and other industries, while China's aluminum production enterprises are more, the production process has caught up with developed countries. But in the process of manufacturing aluminum will inevitably encounter some quality defects, embossed aluminum ring, aluminum quality of the common quality of what is the defect?

Aluminum plate roll

1, composite layer off: composite aluminum layer leaves the substrate, off the formation of irregular defects.

2, embossing: due to strip wrinkles, broken belt and other reasons lead to roll irregular rolling process, the rolling process appears irregular color.

3, wave: plate, ribbon due to uneven deformation of the formation of a variety of different phenomena in general terms. The edge of the wave is called the edge wave. The waves in the middle of the embossed aluminum roll are called intermediate waves. The middle and both sides of the wave is neither in the middle, nor on both sides. They are called two ribs. They are smaller, and the usual wave is called a circular wave.

4, Alice: After rolling or cutting, the embossed aluminum roll is tilted along the belt.

5, curved side: the longitudinal side of the band, said the curved non-flat state.

6, collapse volume: core deformation, volume is not round.

7, the wrong layer: with the surface layer and irregular movement of the layer, resulting in uneven surface

The shape of the tower: the movement between the coil and the layer, forming a tower to move.

9, loose volume: winding, embossing aluminum roll open layer and loose, serious spread to the entire volume of the layer.

10, the nest: the end of the roll has a local "V" type defects. This defect occurs in the process of bending or expanding, some will be placed for some time.

Enterprise technical requirements:

1. Work special coating roll coating application (insulation coating, flame retardant coating, super hard paint, antibacterial coating, water-based paint, etc.)

2. Aluminum environmental protection pretreatment technology (aluminum chrome passivation technology, etc.)

3. Extruded refractory technology (to meet a fire requirements)
