摘要： A refractory assembly includes a refractory outer member having therein an opening defined by an inner surface and a refractory inner member having an outer surface. The dimension of the outer surface of the inner member is greater than the dimension of the inner surface of the outer member by an amount of from 0.05 to 0.15 mm. The outer member is heated to at least 1000.degree. C. to thereby increase the dimension of the inner surface. The inner member then is inserted into the opening in the outer member, and the outer member then is cooled to room temperature. As a result, the inner surface of the outer member shrinks against the outer surface of the inner member to thereby form an interference shrink fit joint between the members.

摘要： A slide gate valve having a cementless joint between the valve and a metallurgical vessel containing molten metal is provided for facilitating the replacement of worn refractory components in the valve. The slide gate valve generally comprises a fixed refractory plate having a flow opening disposed generally in alignment with a tap opening of the metallurgical vessel, a movable refractory plate having at least one flow opening, an air cylinder for reciprocally moving the movable plate with respect to the fixed plate to control the overlap of the flow openings in order to modulate a flow of molten metal through the valve, a spring assembly for pressing the movable plate against the fixed plate to provide both static and dynamic seals between the plate, and a cementless joint between the flow tap of the metallurgical vessel and the fixed refractory plate formed by joint surfaces on the flow tap and the fixed plate which are compressively engageable to form a molten metal tight joint therebetween and compression means, which may be a spring arrangement, for sealingly compressing the mutually-engageable joint surfaces to create a joint without the need for extraneous adhesives or cement. In the method of the invention, the compression means of the joint preferably acts on the fixed plate when the plate is laterally slid away from the flow tap incident to a replacement operation to wipingly clean the joint surface of the flow tap of the metallurgical vessel.

摘要： Techniques are disclosed for renovating sliding gate valve plates or for adapting conventional plates for use with problem-beset metals. Stationary plates (1) have their orifices (2) bored out to downwardly-tapering form and correspondingly tapered prefabricated refractory insert rings (3) are then cemented in place, the rings having axial depths equal to the plate thicknesses. An orificed plate (7) furnished with an integral depending nozzle (12) has its flow passage (13) bored out such that an upper bore portion extending through the plate (7) and part way along the nozzle (12) is transversely larger than the following downstream bore portion. A prefabricated refractory insert ring (9) is cemented into the upper bore portion, ring (9) being substantially as deep axially as the said bore portion. The downstream bore portion is lined with cementitious, metal-reinforced material (14). Materials for the insert rings (3, 9) and cementitious lining (14) are chosen to suit the pouring conditions and metals to be poured.

摘要： An improved device used for teeming liquid metal out of a metallurgical container comprises an efficacious cross section which is formed by the surface of the discharge channel available for the outflow of the metal during the progressive opening of the upper outflow passage. This efficacious cross section is initially kept small and over at least a noticeable part of its length the discharge channel is provided with an active passage portion showing a shaped cross section. This shaped portion stretches down to the lower extremity of the channel and has a form comparable to that one of a star with three to four branches, whereas the grounds of these branches extend axially in the direction of the outflow and serve as guides to the metal during its discharge.
