Description
Short description:
Learn to calculate rolling load, torque, and power in hot rolling using simplified theory and parameter-based estimations.
Long description:
This module focuses on the mechanical principles that govern hot rolling, with a particular emphasis on the forces and energy required during deformation. Learners are introduced to core concepts such as the angle of bite, rolling load calculation using simplified plane-strain theory, and estimation of torque and power required for hot rolling operations. The instructional content guides users through the factors influencing rolling force, including friction, roll diameter, and deformation resistance, and demonstrates how to evaluate the projected length of contact and pressure distribution. Interactive exercises reinforce the understanding of key equations and enable experimentation with parameter variations to predict load and energy demand.
What you will learn
- Explain the concept of angle of bite and its relation to entry conditions in hot rolling.
- Apply simplified plane-strain theory to calculate rolling load in hot rolling.
- Estimate torque and power requirements based on pressure distribution across contact arc.
- Analyze the effect of rolling parameters—such as diameter, friction, and tension—on load prediction.
- Evaluate energy distribution during hot rolling and the dominant sources of consumption.
