ENERGY TRANSFORMATION DURING THE PIERCE PROCESS IN THE PRODUCTION OF SEAMLESS PIPES

Abstract


In the line for production of seamless pipes the pierce and pilger method, also known as the Mannesmann process, are used for the production of seamless tubes. Following the cross roll piercing operation, the tick-walled hollow shell is rolled out in the same internal energy in the pilgering stand, in which the tick-walled hollow shell is elongated to the finished tube dimensions by the discontinuous forging action of the pilger rolls on a mandrel located inside the hollow shell. On the basis of the measured essential parameters, the formulated mathematical model for energy transformations during the piercing process was validated. The model allows the calculation of temperature increment of the rounds depending on the temperature rounds before piercing and consumed electricity of electric motor for drive of the stand rolls.
