摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present invention is drawn to sealing structure for use in guiding molten metal from a metallurgical vessel and the seal thereof. The sealing structure includes first and second generally tubular refractory components one of which extends coaxially within the other with a clearance established therebetween. One of the components also has an annular groove therein confronting the other component at a sealing location. An open-ended elastically deformable spring ring is disposed in the annular groove and is self-biased into sealing engagement with a surface of the component that the annular groove confronts. The spring ring has a semi-annular main body and overlapped end portions extending from the main body.

摘要： An apparatus for mounting a gas washing sink in a centered manner within an opening through a perforated brick in a wall of a metallurgical vessel and for removing the sink from the perforated brick includes a support assembly to be fixedly mounted on the exterior of the wall of the metallurgical vessel adjacent the opening in the perforated brick. A fastening assembly supports the sink and is mounted with respect to the support assembly for movement relative thereto between an operating position, whereat the sink is pressed into the opening throgh the perforated brick in a centered manner, and a maintenance position, whereat the sink is withdrawn from the opening through the perforated brick. Structure moves the fastening assembly relative to the support assembly to the operating position. A withdrawal apparatus moves the fastening assembly relative to the support assembly from the operating position to the maintenance position.

摘要： A tap spout, particularly for allowing molten metal to be discharged from oxygen-steel converters, includes a replaceable unit including a tubular wear lining and a jointing layer secured thereto. An inner lining of the tap spout may thus be repaired with relatively simple maintenance work by removing the inner lining and subsequently inserting the replaceable unit into an outer lining of the tap spout to form a new inner lining of the tap spout. The replaceable unit is adapted to facilitate either a press fit, and in particular, a fit ensured by axial compression of the jointing layer, or an expansion fit with the outer lining to secure the replaceable unit therein.

摘要： An apparatus is disclosed for use in replacing a worn pouring pipe by moving a pouring pipe from a waiting position to a pouring position beneath a discharge opening of a metallurgical vessel, and for use in adjusting flow of molten metal from the metallurgical vessel through the discharge opening. For this purpose, slide rails are provided beneath the metallurgical vessel for supporting head plates of pouring pipe in the waiting position, the pouring position and a discharge position. Also, a linear actuator is provided for pushing the pouring pipe from the waiting position to the pouring position, and can be detachably coupled to the head plate of the pouring pipe so that it can move the pouring pipe in opposing direction to adjust the flow of molten metal through the discharge opening between zero flow and full flow. A base plate can be optionally provided between the metallurgical vessel and the head plates of the pouring pipe, and a second linear actuator can be provied for sliding the base plate relative to the discharge opening of the metallurgical vessel and/or relative to the head plate of the pouring pipe in the pouring position.
