How to calculate the weight of aluminum coil for sale?

The weight of aluminum coils is related to the quotation and price. How to calculate the weight of aluminum coil for sale? This might be something that many people are annoyed with. Then today we will tell you about the standard calculation formula for wall thickness of aluminum coil.

When slitting aluminum coils, we often encounter that the machine does not have a meter counter, so the weight cannot be obtained. At this time, we need to obtain the wall thickness of the required weight. R is the radius of the original aluminum coil, r is the radius of the sleeve or hollow, and R1 is the radius when the weight of the aluminum coil is obtained. Set two more variables: y = the total number of rolls, x = the number of rolls you want to get. (For example, if you want to divide this aluminum coil into 5 coils, then y=5 at this time; if you want to find the wall thickness of 4/5 of this aluminum coil, then x=4 at this time.)

Method/Step

R1=√(x(R²-r²)/y+r²)

(This check mark-like symbol is the square root, which means you have to take the square root.)

Find the radius first, then the wall thickness.

Aluminum coil wall thickness=R1-r

Assume that the radius of the coils is R=55cm, the radius of the hollow without sleeve is r=25cm, and the weight is 2420kg. The client wants 1/5 of the total weight, and the remaining 4/5 is left, and I have to find this position, which is the wall thickness of the aluminum coil when the coil weighs 4/5. At this time x=4, y=5. Bring in the formula as R1=√(4*(55²-25²)/5+25²), and then subtract the hollow radius r from the result, the wall thickness when the weight of the coils is 4/5 is 25.44cm.

Precautions:

It is more troublesome to open the square root, if there is a scientific calculator on the mobile phone, it will be no problem.

So this is how to calculate the weight of aluminum coils. Now have you learned the formula we showed you above? If you want to know the quotation of Haomei aluminum coil for sale, please send us an email. We will then offer you coils with transparent and reasonable price!
