    • A disadvantage during the operation of a change converter unit (1) of an oxygen steel-making plant, wherein converters (4a) that have become unusable due to the wear and tear of the fireproof material are removed from the steel-making stand (2) for repair, and wherein a converter (4b) provided with fireproof material is added in exchange to the steel-making stand (2), is that the connection between the converter vessel and the carrier ring first must be separated, and then either a change carriage provided with a lifting device must be used, or the implementation is limited, or restricted, by the crane capacity when changing AOD converters in stainless steel plants. In order to eliminate said disadvantages, the invention proposes that, for the change process, the worn converter (4a), including the entire converter unit (3a), comprising not only the converter (4a), but also the converter carriage (7), carrier ring (6), tilting drive (5), bottom flushing device (9) and, if present, a carrier ring cooling device (10), is moved out of the steel-making stand (2) into an empty delivery and waiting stand (12s) for repair, and that, at the same time, a further structurally identical complete converter unit (3b), comprising a repaired, ready-to-use converter (4b), is moved from a further delivery and waiting stand (12b) into the steel-making stand (2).
    • 一种用于操作氧气炼钢设备的变换器单元的方法,其中,对于改变过程,包括整个转换器单元的磨损转换器不仅由转换器构成,而且还包括转换器托架,承载环 ,倾斜驱动,底部冲洗装置,如果存在的话,将承载环冷却装置从炼钢机架移出到空的送货和待机台进行修理,同时,进一步结构上完全相同的完整转换器 由修理的即用型转换器组成的单元,从进一步的交付和等待站移动到炼钢站。
