Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:Can kerosene lubricate and cool aluminum coil when continuous punch?
Yes, because water and oil are not solute, but they will emulsificate.
Q:Why does fillet appear when rolling aluminum coil?
How thick and wide is it when there is such problem? Which is the rolling pass? And what is the type of the rolling mill? The simple 4 rollers or CVC and HC rolling mill with roller control. Does the filler appear in rolling or out of roller? Different thickness will lead to different analysis.
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:How much cube is the 0.9mm aluminum rolling?
This is a common problem. Anyone who had received high school education can calculate it very quickily. One way is to calculate sectional area with circular area, then times the thickness of the aluminum rolling. Another way is to use the outer diameter circular area to subtract the core area and then times the thickness of aluminum rolling.
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
Q:What’s the difference between natural cooling and slice cooling?
Cooling with furnace means after thermal insulation, stop heating furnace and make the parts in the furnace cool slowly to the room temperature with the furnace. Natural cooling is a kind of cooling method utilizing fluid circulation based on the fact that density varies with temperature to remove hea
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: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?
It is either because of wrong filling material for welding or bad welding quality. It doesn’t crack after welding, but cracks when the increasing tension in circling process exceeds the internal stress of the weld.
