Q:Which companies will use aluminum sheet and coil?
Plants to make auto parts such as exhaust pipe thermal baffle, muffler thermal baffle and front thermal baffle.
Q:How much is the 25mm aluminum coil at current market?
You must mean 25-wide aluminum coil. The price consists of the aluminum ingot price and processing charges. For example, if the processing price is 4500 yuan, it is relatively cheap. 25mm-wide aluminum coil is very narrow, so it will be much complicated to strip.
Q:How to pull the aluminum coil purchased into aluminum sheet?
You can use decoiler machine, but after decoiling, the embossment of embossed aluminum sheet will become very shallow.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:How to calculate the dosage of paint for aluminum coil coating? If the weight is 1 ton, the density 2.71 and the thickness 0.12mm, how much paint is needed?
Coating surface area S*0.12(thickness)*ρ(density) / solid(paint solid)=actual paint consumption brush and roller paint: 100% spray paint: calculated value*70%
Q:How many 1220mm*2440mm aluminum sheets can one-ton aluminum coil be sliced to? Thank you.
If it is 1.0mm thick, the coil can be sliced into 124 pieces. For other thickness, please use 124 divide the thickness.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
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)
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
That depends on how tight the aluminum coil is. If it is very tight, aluminum will stick together, thus no water can get in.
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
Perhaps there is something wrong in the position controlling the working roller tilt and bend positive and negative convexity, making the working roller out of order and rubbing against the backup roller.
