Modernization of Cooling System for Mandrel of PQF Continuous Rolling Mill at JSC Tagmet

The influence of temperature on the quality of the graphite lubricant layer on the surface of the working part of a mandrel is addressed. In order to modernize the cooling system of the mandrels of a continuous mill in automatic mode so as to equalize the temperature along the length of their working part, the cooling stage of the working parts under standard conditions is analyzed, along with determining the sections where the major deformation occurs. The results of the pilot implementation of a new cooling system in the discussed tooling are demonstrated.
