Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
It is either the external or the bearing problem in designing and installing.
Q:Why does the coated aluminum coil have thickness requirement for membrane?
The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
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: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:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
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 are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:What’s the difference between aluminum tile, coil and sheet? Why?
Wood pallet is often used, which is easy to transport and can ensure the safety of products.
Q:Why does the end face of aluminum coil have grease spots?
Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
