Abstract: A refractory gas permeable injection device for introducing gas into a metallurgical vessel containing molten metal has a surface to be exposed to and progressively worn away by the molten metal during operation of the vessel. The device includes an outer body and an inner body within the outer body, at least the inner body being formed of a fireproof refractory material. A gas permeable space extends through the device in the direction of wear thereof, and the space has a plurality of different geometric shapes spaced in such direction. Upon the metallurgical vessel being emptied, and with the device still relatively hot, gas is caused to flow through the space such that the gas will create on the surface an optically recognizable image in a particular geometric shape as a function of the relative degree of wear of the device.

Abstract: A ceramic part to be used in a high temperature environment and that is preheated prior to use is manufactured by a process including shaping the part and subjecting the part to a heat treatment operation. The heat treatment operation is performed at least partially on location at a position of use of the part in the high temperature environment by a heating device that also is operated to perform the preheating of the part.

Abstract: A composite assembly includes a ceramic inner member and an outer shell member fit around the inner member. The outer shell member is heated and expanded, the two members then are mutually located at predetermined positions relative to each other, and the members are cooled such that the outer shell member shrinks onto the inner member. Heating of the outer shell member is achieved by an inductive heater to result in the predetermined temperature, after which the inner member is moved to the predetermined position thereof relative to the outer shell member, while the outer shell member is maintained at such predetermined temperature.

Abstract: A gas washing sink for use in introducing gas through a metallurgical vessel into molten metal therein includes a gas permeable refractory inner brick portion and a gas impermeable refractory outer brick portion surrounding the inner brick portion. The inner and outer brick portions define a first sink end to be exposed to the molten metal. The outer brick portion has an end face defining a second sink end to be directed away from the molten metal. A gas distribution chamber has a first end open to the inner brick portion and a second end opening onto the end face of the outer brick portion and defined thereat by an opening. A sealing surface extending concentrically of the opening has pressed thereagainst, at a pressure sufficient to achieve a seal therebetween, a closure member for closing the second end of the gas distribution chamber and having a gas inlet connection for introducing gas into the gas distribution chamber.

Abstract: A safety-type gas washing sink for use in introducing gas through a metallurgical vessel and molten metal therein includes a refractory wearable brick portion defining a first sink end to be exposed to the molten metal and becoming worn during use, such wearable brick portion having therethrough gas flow paths for the passage of gas into the molten metal, and a refractory safety brick portion defining a second sink end to be directed away from the molten metal and through which the gas can be delivered to the gas flow paths in the wearable sink portion. The safety brick portion has a higher thermal conductivity than the wearable brick portion, and the gas flow paths continue into the safety brick portion. Thus, any molten metal that breaks through the wearable brick portion to the safety brick portion will be caused to solidify at the safety brick portion due to rapid dissipation of heat thereby.
