Abstract

A new expression for definition rolling efficiency in different roll sequences passes accounting roll passes shape influence and correlation between contact resistance in cross and longitudinal direction was obtained. It was determined that the smallest coefficient of effectiveness takes place in rolling sectional bars with free spreading and it rises with increasing of roll pass walls inclination angle.
