Description

Technical Field

[0001] The utility model belongs to the technical field of slide plate installation of a ladle, and more specifically relates to a slide plate installation structure of a ladle and the ladle. Background Art

[0002] The sliding nozzle mechanism of the ladle is a pouring mechanism installed at the bottom of the ladle and used to control the opening and closing of the molten steel flow nozzle and quantitative throttling. The main structure consists of two parts: the mechanical part and the refractory part. With the increasing number of large-capacity ladles in China, the requirements for the precise installation of refractory materials are also getting higher and higher. Figure 1 As shown, on the B3-2 mechanism, a tightening mechanism 6 is used to tighten the slide plate 4, the purpose of which is to position the refractory material better and more accurately in the mechanism, and to prevent it from moving during use. At present, the tightening mechanism 6 of the positioning slide plate 4 of the B3-2 mechanism is all at the lower end of the mechanism, that is, when the ladle is in a tilted state, the bottom plate 1 of the ladle stands upright, at this time the tightening mechanism 6 is at the lower end of the slide plate cavity 2, and the slide plate 4 is above the tightening mechanism 6; when in use on site, steel slag or fire mud slag will fall in, causing the internal structure of the tightening mechanism 6 to get stuck, and the slide plate 4 cannot be tightened, and then a safety accident will occur. At the same time, since the slide plate 4 weighing about 15 kilograms is above the tightening mechanism 6, the operating force is large, and it is more laborious when tightening. The tilting state of the ladle refers to that during the normal use of the ladle, such as when the ladle is hot-repaired online, the ladle only tilts in one direction, and it is in a tilting state after tilting.
