Eugene F Cook

US Patent:

51748355, Dec 29, 1992

Filed:

Nov 20, 1990

Appl. No.:

7/615900

Inventors:

Eugene A. Cook - King of Prussia PA
Robert J. Mieloo - Hamilton, CA

Assignee:

Selas Corporation of America - Dresher PA

International Classification:

C21D 126

US Classification:

148510

Abstract:

Strip elongation in a continuous annealing furnace is controlled by passing the strip around a first driven roll, then through a portion of the furnace, then around a second driven roll, wherein the elongation of the strip is sensed. One method is to sense the amount by which the peripheral speed of the second roll exceeds the peripheral speed of the first roll. Roll speeds are monitored by precision resolvers. Another method is to utilize a strip width measurement to determine elongation. Mechanisms are used for profiling tension throughout the furnace length.
