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： 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.

摘要： An apparatus repairs a perforated brick employed in a wall of a metallurgical vessel and having an opening into which is to be fit a gas washing sink for introducing gas into molten metal within the metallurgical vessel, during which gas introduction the inner end of the gas washing sink and the perforated brick around such area become worn. The apparatus includes a casing having an outer contour corresponding to the outer contour of the gas washing sink and to be inserted into the worn opening of the perforated brick upon removal therefrom of the worn gas washing sink. The casing thus forms a template defining the contour of the opening to be repaired in the worn portion of the perforated brick. A repair material feed pipe extends through and is guided by the casing for supplying therethrough repair material for repairing the worn portion of the perforated brick. A spray head is attached to the inner end of the feed pipe for directing the repair material toward the worn portion of the perforated brick.

摘要： A tapping pipe is provided for a melt vessel having a predetermined melt maximum bath level X.sub.m. The tapping pipe defines a flow passage therethrough which has a discharge zone having flow cross-sections approximately the same as the cross-sections of the flow profile of a free flowing stream of the melt from a melt bath level X.sub.0 between 30% and 70% of the maximum melt bath level X.sub.m. The discharge zone can be provided by a brick defining the discharge zone, together with additional bricks defining a feed zone and a transition zone between the feed zone and the discharge zone. In making a number of replacements of the tapping pipe in a converter, the length of the brick defining the transition zone can be gradually reduced so as to compensate for the wear of the converter lining.

摘要： 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.

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 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.
