Assignee:

ISG Technologies Inc. - Richfield OH

International Classification:

B21B037/28

US Classification:

72 91, 72 74, 72 114, 72205, 723652, 700154

Abstract:

A method for measuring and displaying the flatness of a rolled steel sheet is disclosed that includes the steps of measuring tension in the sheet at a plurality of locations on the surface of the sheet and determining a plurality of tension ranges into which the sensed tension level can fall. A color is associated with each of the tension ranges, and a representation of the sheet is produced that is made up of a plurality of regions, each region having a color corresponding to tension range into which the tension sensed at the corresponding location on the surface of the sheet falls. A device for carrying out this method is also disclosed.

Filed:

Jun 14, 1989

Appl. No.:

7/365819

Inventors:

Thomas J. Russo - Kingsville MD

Assignee:

Bethlehem Steel Corporation - Bethlehem PA

International Classification:

B22D 1104

US Classification:

164416

Abstract:

A continuous caster vibrating mold assembly having lever arms each with a pivot pin including a hollow tubular sleeve having open ends for encircling a removable load cell having strain gauges attached thereto for measuring loads on a pivot joint. When loads are placed on a pivot joint the load cell will deflect and its deflections are detected by a strain gauge which measures the axial deflection of the load cell.

Appl. No.:

7/674481

Inventors:

Thomas J. Russo - Kingsville MD

Assignee:

Bethlehem Steel Corporation - Bethlehem PA

International Classification:

B22D 4108

US Classification:

222600

Abstract:

A molten metal slide gate valve for use on a ladle or tundish. The slide gate valve uses a refractory plate or plates having a shallow groove all around the periphery of one or both surfaces of the plate. The groove surrounds the molten metal orifice in the plate. The base of the groove has a porous refractory insert connected to a source of nonoxidizing gas under pressure to provide a nonoxidizing gas seal all around the molten metal orifices in the slide gate valve and to prevent the aspiration of air into the molten metal orifices during discharge of the molten metal from the ladle or tundish.

US Classification:

222600

Abstract:

A molten metal slide gate valve for use on a ladle or tundish. The slide gate valve uses a stationary upper plate having a groove formed in its lower face around the periphery of the plate. The groove is connected to a source of a nonoxidizing gas under pressure to provide a gas seal around the molten metal orifices in the slide gate valve and prevent the aspiration of air into the molten metal orifices during discharge of the molten metal from the ladle or tundish.

Inventors:

Thomas J. Russo - Kingsville MD

Assignee:

Bethlehem Steel Corporation - Bethlehem PA

International Classification:

B22D 4114

US Classification:

266230

Abstract:

Apparatus for retaining slag in a tundish or a ladle or similar vessel containing molten metal such as used in the steel industry. A refractory nozzle member and a refractory retainer member are secured to the bottom of the vessel around the molten metal discharge orifice. A refractory plug member of a density between that of the molten metal and the slag is positioned laterally within the retainer member but free to move vertically during discharge of the molten metal from the vessel.
