The calculation of temperature increment during the cross roll piercing operation

The article presents formulated mathematical model for calculating the temperature increase of the the tick-walled hollow shell, during the cross roll piercing operation, depending on the initial temperature of the round as well as the electric energy consumed for drive of the work rolls. On the basis of the measured essential parameters, the formulated mathematical model for energy transformations during the piercing process was validated.
