Engineering

FM®-rolls are optimally calculated and designed to the respective customer specific operating conditions using the latest computer programs and the finite element method (FEM).

Strength verification in accordance with DIN 743 Standard,

taking account of:

  • All known forces and loads
  • The core geometry with all form and surface influences
  • The material

Calculation of the required crowning of the coating

compensating roll deflection in operation and ensuring a consistent line pressure,

considering:

 

  • Radial forces and line load
  • Net weight of the roll
  • Bearing stiffness
  • Additional impact forces
