Abstract

802,010. Altering physical structure; working at specified temperatures; rolling. BOCHUMER VEREIN FUR GUSSSTAHLFABRIKATION A.G. May 31, 1957 [June 6, 1956], No. 17422/57. Addition to 798,652. Class 83 (4). An improvement or modification of the process claimed in the parent Specification is characterized in that with the electrical current supplied through the roll, the direct electrical resistance heating in the roll gap to temperatures of just below AC3 is effected with the simultaneous use of water as a direct coolant for the outside of the roll, so that a slight film of water, possibly just changing into steam, is provided between the roll and the material being rolled.
