Rolls for Section Mills
To determine the correct roll material for the profile-steel rolling mills one has to compare the specific rolling mill conditions and the material properties of the roll. The following essential points have to be taken into consideration:
Roll Factory Conditions:
- Type of Stand
- Type of roll product
- Mechanical demands (rolling pressure, driving torque and stock-reduction)
- Roll calibration (initial pass and finish pass, bite angle and max. depth of pass)
- Temperature demands (rolling temperature, -speed, roll cooling)
Properties of the roll material
- mechanical properties (tensile- and bending strength, high thermal strength, modulus of elasticity)
- surface hardness - radial hardness drop
- wear resistance
- Fire-crack resistance
- Gripping capacity (Friction coefficient)
- Oxidation stability
Please take note of our roll material overview and material recommendations on the right.
