Ladle nozzle sand tank filling device

Abstract

The invention discloses a ladle nozzle sand tank filling device and belongs to the technical field of steelmaking equipment. The ladle nozzle sand tank filling device comprises a hoisting ring (1), aconnection rod (2), a locking device (3), a locking plate (4), a baffle plate (5), a material tank (6), a bell (7), a funnel (8), a bracket (9) and a refractory material (10); the hoisting ring (1) iswelded with the connection rod (2) which is tapped with outside threads; the locking device (3) is screwed on the connection rod (2); the baffle plate (5) and the locking plate (4) are sequentially welded to the manufactured material tank (6); the manufactured hoisting ring (1) and connection rod (2) penetrate through the material tank (6), and then the bracket (9) is welded to the funnel (8); and finally, each of the outer surfaces of the material tank (6) and the funnel (8) and the bottom surface of the bell (7) is coated with a layer of refractory material (10). The ladle nozzle sand tankfilling device has the advantages of simple structure, strong applicability, reliability in running, simpleness in operation, time and labor conservation, convenience in maintenance and the like.

Description

technical field [0001] The invention belongs to the technical field of steelmaking equipment, and in particular relates to a ladle nozzle sand filling material tank device, which can be used for both online ladle nozzle sand filling and offline ladle nozzle sand filling. Background technique [0002] Before the ladle receives steel, it is necessary to pour sand into the nozzle of the ladle whose internal temperature is as high as about 1000°C, so as to facilitate the smooth drainage of the nozzle of the ladle when it is poured. At present, the sand filling methods of ladle nozzles in various steel plants mainly include manual throwing, hoisting and loading assisted by cranes, and special tool filling, etc. Manual throwing will cause a certain amount of waste of sand and the effect is unstable. The latter two methods produce almost no waste. The use effect is also good, and it has a wide range of applications in actual production. [0003] The invention belongs to the catego...
