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.

Appl. No.:

5/934627

Inventors:

Eugene A. Cook - Lansdale PA
Chad F. Gottschlich - Philadelphia PA

Assignee:

Selas Corporation of America - Dresher PA

International Classification:

C23C 102

US Classification:

427321

Abstract:

Sealing means for preventing metal vapor, and in particular zinc vapor, evolution from the surface of a bath into a furnace is provided at the exit end of the heat processing industrial furnace through which a continuous metal sheet is advanced. Upon exiting the furnace the metal sheet is dipped into a bath for hot dip coating thereof. At the zone of the industrial furnace from which the continuous metal sheet exits the furnace and advances into the coating bath, there is provided therein an atmosphere having a low dew point and a relatively high hydrogen content to thereby reduce the oxidation of the metal vapor which may have migrated into the furnace. Furthermore, sealing means are provided between zones of the furnace to retain the integrity of this atmosphere, and thus isolating zones having different atmosphere compositions.
