Calculate steel coil weight

To calculate the weight of a steel coil, it is necessary to consider its width, external diameter and internal diameter. Using the correct formula, it is possible to obtain the weight accurately. Let's explain how to do this calculation:

Calculating Coil Weight

The formula for calculating the weight of a steel coil is:

𝑃 = ( 𝜋 × ( 𝐷 𝑂 two − 𝐷 𝐼 two ) × 𝐿 × 𝜌 4 × 1000 )

Where:

  • 𝑃 is the weight of the coil in kg;
  • 𝐷 𝑂 is the outer diameter of the coil in mm;
  • 𝐷 𝐼 is the internal diameter of the coil in mm;
  • 𝐿 is the coil width in mm;
  • 𝜌 is the density of the steel, assumed to be 7.85 g/cm³.

For example, suppose we have a steel coil with the following values:

  • External diameter (OD) = 1000 mm;
  • Inner diameter (ID) = 500 mm;
  • Width (L) = 1500 mm.

Substituting these values ​​into the formula, we obtain:

𝑃 = ( 𝜋 × ( 100 0 two − 50 0 two ) × 1500 × 7 , 85 4 × 1000 )

Calculating, we have:

𝑃 = ( 3 , 1416 × ( 1000000 − 250000 ) × 1500 × 7 , 85 4 × 1000 )

𝑃 = ( 3 , 1416 × 750000 × 1500 × 7 , 85 4 × 1000 )

𝑃 = ( 3 , 1416 × 1125000000 × 7 , 85 4 × 1000 )

𝑃 = ( 27787740000 × 7 , 85 4 × 1000 )

𝑃 = ( 218280890000 4000 )

𝑃 = 54570222 , 5 g

Converting to kilograms, we have:

𝑃 = 54570 , 22 kg

Therefore, the weight of the steel coil is approximately 54570.22 kg.

With the correct formula and appropriate values, it is possible to calculate the weight of a steel coil accurately. This calculation is essential for several industrial processes that involve the handling and transportation of steel coils.
