    Abstract: 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.

    Abstract: A refractory plate for a sliding gate valve at the outlet of a vessel containing molten metal has a polygonal external shape and has a longitudinal axis, on both sides of which at least two side surfaces, disposed at an obtuse angel (.gamma.) to one another, extend and serve as clamping surfaces of the plate in a metallic frame (11) or the like. The shorter side surfaces are arranged to extend at an angle (.alpha.) of between 20.degree. and 50.degree. to the longitudinal axis while the longer side surfaces are arranged to extend at an angle (.beta.) of between 10.degree. and 30.degree. to the longitudinal axis. The refractory plate can thus be optimally clamped and an increased service life is thus consequently achieved.

    Abstract: 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.

    Abstract: 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.

    Abstract: A refractory wear part for use in a sliding closure unit for a metallurgical vessel has therethrough at least one flow-through opening. The wear part is formed of a combination of gas permeable material and gas impervious material. The wear part includes at least one gas flushing zone formed of the gas permeable material and opening on a surface of the wear part. A gas duct connects the flushing zone with an external gas inlet connection. The gas duct and the flushing zone are formed as a unitary, homogeneous gas permeable structure from the gas permeable material, and such gas permeable structure is formed within a gas impervious base structure formed of the gas impervious material.

    Abstract: A gas washing device for supplying gas through a metallurgical vessel to molten metal therein includes a gas permeable sink positioned to extend through a wall of the metallurgical vessel. The sink has an inner end to be exposed to the molten metal and subject to wear thereby and an outer end. A gas inlet supplies an operational flow of gas from a gas supply to the outer end of the sink. A device is operatively mounted with respect to the sink and is responsive to a temperature rise indicative of a predetermined extent of wear of the inner end of the sink by the molten metal, to reduce the flow of the gas to a reduced flow less than the operational flow upon the inner end of the sink being worn or eroded to the predetermined extent. A detector detects or measures the reduced flow of gas.

    Abstract: An annular space is formed between the opening of a refractory lining in a metallurgical vessel and a shaped element to be joined to the refractory lining in the opening. A joint packing is provided to be packed in the annular space. The joint packing is an annular, deformable, prefabricated packing adapted to the volume or the shape of the annular space. The joint packing is fixable in position in either the opening of the refractory lining or on the shaped piece when the joint arrangement is assembled. Preferably, the joint packing comprises a packing compound provided in a sleeve.
