摘要：The sliding closure (20) is arranged at an outlet (15) of a converter (10)
containing a bath of molten metal and has a refractory ba plate and a refractory slide plate for the purpo of opening and closing the converter outlet. Preferably three additional refractory closure plates are alingly arranged between the ba plate (22)and slide plate (24), which closure plates are either fixedly cured to the ba plate (22)or el are displaceable together with the slide plate (24). A decisive factor in the prent invention is also that a number of closure plates (23) are provided between the slide
plate (24) and the ba plate (22) such that with the an overall plate durability is achieved which corresponds to that of the refractory sleeves (16) ud for the tap hole. During the operation of the converter (10), first of all only the slide plate (24) is displaced, while the closure plates (23) are held immovably with their flow-through openings concentric to that of the ba plate (22). When the slide plate (24) is worn, the latter is moved together with the next closure plate (23) up to open and clo the closure (20) and, when this plate is worn, the next closure plate (23) is moved, until the ba plate (22), the slide plate (24) and the closure plates (23) are all worn. By means of the coupling mec
检讨模板hanism (30) arranged in the sliding closure (20), the closure plates (23) are in each ca either coupled with or uncoupled from the slide plate (24) or el the ba plate (22). Conquently, by means of the invention considerable advantages are achieved in terms of handling and with regard to the operation of the converter compared with the u of a known sliding closure.
