Studies on the Application of the Heated-Roll Concept to Hot Rolling Metals.
Abstract
The report describes a study conducted to determine the application of the heated-roll concept to hot rolling various metals. Superalloy roll surfaces were induction heated to as high as 1500 F. The mill operation was satisfactory inasmuch as (1) the roll surface target temperature could be attained after a ten minute heat-up time, (2) heating the rolls by induction produced a very localized heated zone, (3) a steep temperature gradient could be maintained without ill effects to the rolls or bearings by proper water cooling. Relatively thin strip could be rolled on the mill but foil thicknesses could not be fabricated because of the large (8-inch) work roll diameter. Rolling trials were continued on tungsten, beryllium, TD-Cr-Ni alloy, Ti-6Al-4V alloy, 8670 steels, and two superalloys to develop processing parameters using heated rolls. (Author)
