Hot rolling and rolling defects - nptel.ac

1. Hot rolling and rolling defects: 1.1 Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can reduce roll diameter, or reducing the friction.
