Q:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
Q:What are the production processes of aluminum coil and what are the functions of various industrial furnaces in the production of aluminum? The more detailed, the better. Thank you! Points!
General steps are as follows: melting - hot rolling - cold rolling - annealing – shearing – straightening – punching
Q:Why do the layers loose when taking out coil after roll of aluminum 0.14?
After rolling, the most possible reason may be poor deoiling effect. I think, for 0.14mm aluminum coil, the lining sleeve will not be forgotten. After rolling , oil ooze from aluminum layers, and the support of aluminum coil is not enough, leading to coil collapsing. The specific manifestations are that the edges of even round aluminum layers become like water ripple, and that the aluminum coils suddenly become uneven when taking out coil.
Q:Can the displacement sensor be used for real-time measurement of the aluminum coil thickness?
Yes, you can use two sensors to measure thickness, either contact sensor or laser sensor
Q:Why there is arc panel after aluminum coil straightening?
The aluminum coil can only become flat and straight after being planished on stretch bender.
Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:How to identify the quality of color coated aluminum coil and sheet?
Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
