| 266271000 | MEANS SEALING OR OPENING APERTURE IN VESSEL | 8 |
| 20130099432 | FURNACE REFRACTORY BRICK HEARTH TAP HOLE - A method for accommodating increasing outward pressures in the tap holes of a hearth furnace includes configuring a tap hole lining and disposing it inside a hollow cylindrical conduit such that the tap hole lining can slide in response to outward pressures and growth in the hearth brick. The tap hole lining is retained inside the hollow cylindrical conduit with a retaining ring and spring assemblies. | 04-25-2013 |

| 20080224367 | Pit Furnace Closing System - “PIT FURNACE CLOSING SYSTEM” comprising the use of two beams and several square iron bars laid across the border of the furnace and supported over said beams, and pieces of cloth wrap for high temperature are used for closing the furnace or a species box in a stainless steel screen was further developed, folded and having a ring, and filled in with remains of wraps, or even a biparted lid in a thin plate with wraps fixed to it and a cut for the upper part of the supporting device of the parts to pass, which is the “cage”-like one, and suspended inside the furnace and supported in the two beams, not resting on the floor of the furnace, and said furnace has thermopairs, which may be in contact with the part entering into the mouth of the furnace, or may be loosen ones, and their heating ends are located in the central direction of each heating zone (thermopairs bar), and for having a variant foreseen with oil heating and having a rectangular format, which is coated with refractory bricks fixed with stainless steel pins. An end of the pin is welded in the plate of the furnace and the other part is welded in a square plate, which may contain a possible movimentation of the vertical walls of the furnace, and the burners may be fed with diesel oil or with viscous fuel oil. | 09-18-2008 |
| 20090152778 | Stopper Rod - A stopper rod for controlling the flow of molten steel from a tundish has a metal carrier element partly received in an internal passageway of the stopper rod, the carrier element compressing sealing means between a frustoconical undersurface of a laterally enlarged portion thereof and a complementary seating surface of the stopper rod passageway, there being an insert threadedly engaged with one of the carrier element and stopper rod body at a position above a laterally enlarged portion of the carrier element, with further sealing means disposed between said insert and the carrier element. Preferably the insert is a nut screwed down onto a washer which compresses the further sealing means. | 06-18-2009 |
| 20090315234 | SEALING APPARATUS FOR A SLAG DOOR OF A METALLURGICAL FURNANCE - A sealing apparatus for a slag door of a metallurgical furnace, having a mounting assembly for mounting the apparatus to the furnace, and at least one closure element, moveable from an open position that is exterior of the slag door opening, to a closed position that effectively seals against the slag door and extends into the slag door opening with the rear panel of the closure element(s) being proximally aligned with the interior wall of the furnace. The apparatus may also have at least one wiping component moveable so as to sweep across the lower surface of the slag door to remove obstructions. | 12-24-2009 |
| 20110148013 | Sealing Plug for Tiltable Converters - A sealing plug | 06-23-2011 |
| 20120086158 | SEALING PLUG FOR AN OUTLET OPENING OF A CONTAINER AND CONTAINER HAVING A SEALING PLUG - The invention relates to a sealing plug for an outlet opening of a container which accommodates a liquid melt. The sealing plug has a sealing region disposed on the outer surface thereof that is configured to come into contact with a section of the delimiting wall delimiting the outlet opening in order to close the outlet opening. The sealing plug narrows from the sealing region towards a front end along the longitudinal axis of the sealing plug. The front end is configured for insertion into the outlet opening, wherein a section between the sealing region and the front end is designed to have a concave shape. | 04-12-2012 |
| 266273000 | By means injecting plugging compound, e.g., mud gun | 2 |
| 20100320654 | TAP HOLE PLUG GUN - The embodiments of the invention relate to a tap hole plug gun for metallurgical furnaces, having a pressure cylinder for receiving the plugging compound, which has a closable filling opening for the plugging compound, and having a plugging piston for pressing the plugging compound out from a mouthpiece of the pressure cylinder pressed against the tap hole of a furnace. The pivotable safety flap for closing the filling opening of the pressure cylinder for the plugging compound is equipped with a stop, which is pivoted into the cylinder chamber of the pressure cylinder upon opening of the flap to decelerate an unintentional forward stroke of the plugging piston for pre-compression and expulsion of the plugging compound, and is pivoted out of the cylinder chamber upon closing of the safety flap. | 12-23-2010 |
| 20120292836 | Clay Gun Machine Cannon for Metallurgical Furnaces - The invention relates to a clay gun machine cannon ( | 11-22-2012 |
