If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours.

The exact roll length should be measured during winding of web or spooled goods. Winding takes place at the end of the production, or when rewinding from large rolls into small rolls, means from mother roll/tambur to rolls with vending length. This may happen at high acceleration and high speed. Contact measurement systems, such as friction ...

Work Roll Diameter. Work roll diameter and center distance in a roller leveler determine the machine's thickness capacity (see Figure 3). Minimum thickness is determined by how small of a radius the material can be bent into with a given roll size. Maximum thickness is determined by the maximum load a given roll can safely and reliably handle.
To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.
