Joseph A. Perri - Coraopolis PA

Assignee:

Insul Company, Inc. - East Palestine OH

International Classification:

C21C 544

US Classification:

266281

Abstract:

A liner for a molten metal receiving tundish in the form of appropriately sized and shaped inserts formed of insulating and/or exothermic containing materials is assembled on a supporting frame which may be reusable or expendible and positioned in the tundish where the liner acts to fully protect the tundish interior from molten metal contact or penetration.

Filed:

Jul 6, 1987

Appl. No.:

7/070057

Inventors:

Micheal D. LaBate - Ellwood City PA
Joseph Perri - Coraopolis PA
Jeffrey Towns - New Waterford OH

Assignee:

Insul Company, Inc. - East Palestine OH

International Classification:

C21C 548

US Classification:

266100

Abstract:

Refractory erosion detection devices are positioned in the refractory lining of metallurgical vessels, such as ladles and refractory stirring plugs incorporated in such vessels through which stirring gas is directed, comprise metal rods positioned in the upper or outer portions of the refractory bodies with their inner ends spaced from the opposite surfaces of the refractory body so that molten metal introduced into the metallurgical vessels erodes the refractory bodies and the metal rod to a point where the complete erosion and absence of the metal rods visually indicates the pre-determined thickness of the remaining refractory bodies indicating the need of replacement of the same.

Filed:

Jul 30, 1990

Appl. No.:

7/559835

Inventors:

Joseph A. Perri - Coraopolis PA

Assignee:

Insul Company, Inc. - East Palestine OH

International Classification:

C21C 546

US Classification:

266217

Abstract:

This invention provides an apparatus for automatically connecting a gas supply to a vessel employed to contain molten metal whereby gas, such as argon, is injected into the molten metal in a selected interior portion of the vessel, such as a ladle. The ladle is positioned on a tilting structure so that it can be tipped to flow out slag on the top on the molten metal, the slag and other impurities in the metal being directed to the top thereof by the upwardly flowing argon gas. The apparatus comprising an upstanding male connection mounted on the tilting structure so as to be engageable in a downwardly facing female connection mounted on the ladle. The connections are shaped to insure a substantially gas tight connection whereby gas in a desired volume at a desired pressure are introduced into the ladle.

Appl. No.:

7/193566

Inventors:

Joseph A. Perri - Coraopolis PA

Assignee:

Insul Company, Inc. - East Palestine OH

International Classification:

C21C 548

US Classification:

266266

Abstract:

A device for introducing stirring gas into a mass of molten metal in a container by way of an opening in the container and a pocket block having a plurality of metered passageways extending therethrough, the pocket block forming a portion of a refractory lining in said container, the plurality of passageways being defined by a plurality of metal tubes arranged in a spiral configuration in circumferentially spaced relation to one another in fixed position in the pocket block which is formed of a suitable refractory, preferably vitrified. The plurality of metal tubes communicate with the single tube which extends through the bottom of the container and communicates with a supply of gas, such as argon.

Filed:

Appl. No.:

5/727281

Inventors:

Joseph Perri - Coraopolis PA

International Classification:

B22D 706

US Classification:

249106

Abstract:

The use of hot tops on ingot and similar molds in which steel, steel alloys and other molten metal are teemed and cooled to a solid state is avoided and the use of topping compounds in such operations eliminated or substantially reduced by the provision of a removable and reusable cover covering the top of the mold cavity wherein the cover comprises elements combined into a single unit arranged to be set atop the mold and completely cover the metal, at least one of said elements having a heat-reflecting surface over the undersurface thereof for reflecting heat downwardly onto the metal in the mold to retard the cooling of the metal while the space or spaces between the elements provide insulation. At least the lowermost reflective element in the assembly may slope downwardly and inwardly toward the center of the cover, that is, they diverge upwardly from a central area toward the side walls so that radiant heat will be deflected downwardly and outwardly to retard cooling of the metal near the top from the sides toward the center.

US Patent:

Filed:

May 6, 1985

Appl. No.:

6/731011

Inventors:

Michael D. LaBate - Ellwood City PA
Joseph A. Perri - Coraopolis PA

Assignee:

Insul Company, Inc. - East Palestine OH

International Classification:

B22D 4110

US Classification:

266272

Abstract:

A device for the separation of slag and its retention in a tapping converter, such as used in the steel industry, consists of a closure having a specific gravity lower than that of the steel produced in the converter, but higher than that of the slag, provided with an elongated guide member depending from the closure, the tip portion of the guide member having a configuration including pockets for the molten steel and an exterior shape against which the molten steel flowing into the tap hole of the converter engages to accelerate and align the guide member and the closure into registry with the tap hole.
