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 the aluminum-plastic panel processed by color aluminum coil peel off paint?
Generally speaking, aluminum-plastic panel will not peel off paint. If it does happen, the quality of the aluminum-plastic panel is very poor.
Q:What’s the loss rate per kg when processing aluminum coil to aluminum sheet?
Q:How to calculate the length of aluminum sheet with the thickness known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width). Ps: Keep unit the same.
Q:What does it mean to slice aluminum coil by decoiler machine?
The operating procedures of decoiler machine: 1, Select appropriate aluminum coil according to production work order requirement to be processed, paying attention to the thickness, width and material of aluminum coil. 2, Put the aluminum coil into the coil loading car with traveling crane and inch the car into the uncoiler. The aluminum coil and decoiler machine should be in the same direction. Hold the aluminum coil down with leading head, and open the auxiliary bearing. 3, Turn on the shovel head, and inch the uncoiler to lead the aluminum sheet into the leveler. Adjust the leveler according to the thickness and width of aluminum sheet to ensure the flatness. 4, Turn on the front gap bridge and back gap bridge in control main platform, inch the leveler to lead aluminum sheet into re-leveler. Adjust the re-leveler to ensure the flatness of aluminum sheet. Put it into the shear gauge and plate shearer. 5, Take back the front and back gap bridge. Inch the plate shearer to cut off the sheet head and shear the aluminum sheet according to production work order. Check the first sheet to see whether it meets the quality standard and whether there is defect in flatness, length, diagonal, and surface of aluminum sheet. If it is qualified, turn on the conveyor. Put the aluminum sheet holder on the pallet. Adjust the pallet according to the width and length of aluminum sheet. Input quantity and length on the control main platform. Then turn on the auto control to produce automatically. The production process can be observed at any time. 6, If there is aluminum coil left, unwind, package and put it into storage in reverse steps.
Q:Why the aluminum sheet crack after?
Maybe the crack existed during welding but you didn’t notice. And then it expands and becomes obvious when acted on by external force in circling process. The reason may be the welding craft. Besides, I suggest more comprehensive tests after welding, such as penetrant test.
Q:Can aluminum coil 3003H24 replace 3A21H14?
It is ok in some way as both of them are alumal. The hardness of 3003H24 is similar to that of 3A21H14 after hardening without annealing. Both have good corrosion resistance, plasticity and bad machinability. They cannot be used as load bearing parts even though small load is ok. They cannot be anodized.
Q:What is color aluminum coil?
Colored aluminum coil is that the aluminum alloy whose surface has been shaded. The surface color after special treatment will not fade within 30 years at least because of the stable performance and good corrosion resistance. The weight per unit volume of color aluminum coil is the lightest among metal materials because of the low density and high hardness. Color aluminum is a newly emerging material in the field of doors and windows. Compared with steel, the biggest advantage is unparalleled firmness, varied colors and non-toxic for which steel has always been blamed. Therefore, it is widely used in areas such as doors and windows, sunroom and balcony seal. Color coated aluminum coil has become one of the most popular decorative material which is environmentally-friendly, durable and aesthetic. As a decorative material, it has the following unparalleled advantages: uniform color, bright and clean, strong adhesion, durability, anti-acid and anti-alkali, corrosion resistance, wind and weather resistance, decay and abrasion resistance and ultraviolet proof. Products categories: polyester coated aluminum coil (PE) and perfluorocarbon coated aluminum coil (PVDF).
Q:How many companies have used aluminum coil?
Too many. All the companies who make the aluminum products you have seen in daily life have used it. So it is hard to explain.
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
