Filed:

Feb 17, 1977

Appl. No.:

5/769496

Inventors:

Frederick S. Lukac - New Kensington PA
William P. Zbryski - Tarentum PA

Assignee:

Allegheny Ludlum Industries, Inc. - Pittsburgh PA

International Classification:

B08B 310

US Classification:

134104

Abstract:

A strip is continuously passed through a molten salt bath in a main tank having a central longitudinal baffle providing passageways at each end thereof. A sink guide roll is provided for the strip at the exit half of the tank. A heating tank is located along one longitudinal side of the main tank at the entry end thereof and has front and rear connecting openings with the main tank. An agitator is positioned at the front end of the heating tank. A forward tank section located along the other side of the tank has a bottom opening connecting therewith. An intermediate tank section has upper and lower compartments, the upper compartment serving as a sludge settling basin. A rear tank section has an agitator therein and is connected to the forward tank section through the lower compartment. Small openings adjacent the top of the upper compartment open into the main tank and to the rear tank section. The bath is continuously circulated from the rear tank section back around the baffle, forward into the rear end of the heating tank, through the heating tank and across the front end of the main tank into the forward tank section and then back into the rear tank section.

Assignee:

Allegheny Ludlum Industries, Inc. - Pittsburgh PA

International Classification:

B08B 304

US Classification:

134 64R

Abstract:

In treating certain types of steel strip, it passes through a plurality of processes including a salt bath having a driven sink roll therein. In order to by-pass the salt bath means are provided to raise and lower the sink roll and its drive while maintaining them horizontal. This permits changing from one type of strip which is subject to the salt bath to another type of strip which is not subject to the salt bath without rethreading the entire line. A guide roll at the exit end of the salt bath tank is below and out of contact with the strip which has been in the salt bath, but is raised into contact with strip which by-passes the salt bath. A baffle is provided to cover the guide roll in its lower position and uncover it in its upper position.
