Abstract
The utility model provides a double-vacuum cast steel ingot middle ladle, and belongs to the technical field of large steel ingot vacuum pouring. A heat preservation layer is arranged between a steel frame and an erosion layer of the middle ladle. Pouring materials are filled in the heat preservation layer. The erosion layer is formed by a plurality of agalmatolite bricks in a building mode. Agalmatolite silica chamotte is arranged between the agalmatolite bricks. An air brick and a slide water opening device are arranged on the bottom-wrapping erosion layer. The slide water opening device comprises an upper slide plate, a lower slide plate, a water opening brick cup and a vent plug. Water openings are formed in the upper slide plate and the lower slide plate. The vent plug is arranged on the lower slide plate. A plurality of slots are formed along the longitudinal direction of the vent plug. According to the double-vacuum cast steel ingot middle ladle, spinel and other high alumina linings of the middle ladle used during vacuum pouring are replaced, the problem that a large amount of residue steel is adhered to the inner wall of the middle ladle can be effectively avoided, the slide water opening device replaces a plug rod mechanism to achieve middle ladle pouring, the problem that a plug rod is replaced each time is solved, the vent plug is arranged on the lower slide plate of the slide water opening mechanism, the refining effect is improved, and a small quantity of impurities adhered to the wall of the ladle are removed from molten steel.
Description
Technical field
The utility model belongs to large steel ingot vacuum casting technique field.
Background technology
Tundish is the key equipment of large steel ingot when vacuum pouring, it is also the key equipment that ensures vacuum, play simultaneously the stabilized steel water flow field, impel the further effect of floating of field trash, some have also installed the argon gas stopper rod additional and have been beneficial to and reach better degasifying effect when opening middle water containing opening and vacuum pouring.Current, the vacuum caststeel ingot tundish of each enterprise at home and abroad, the multiplex High-Alumina of tundish lining refractory brick or spinel, the very easily sticking residual steel residue of bulk that stays of tundish inwall, clear up residual steel and residue after needing after pouring tundish temperature is dropped to room temperature, then reconditioning cast gate again, reheat more than 800 ℃ and can reuse stopper.Stopper in tundish originally reuses inconvenience, and during the cleaning residue, labor strength is large, work under bad environment.
Summary of the invention
The purpose of this utility model is to provide a kind of pair of vacuum caststeel ingot tundish, reuses inconvenience with the stopper that solves in the original tundish of prior art, and during the cleaning residue, labor strength is large, the problems such as work under bad environment.
The utility model mainly is comprised of steel skeleton, permanent layer, air brick and erosion layer, solve technical scheme that its technical problem adopts and be steel skeleton and corrode between layer heat-insulation layer is set, heat-insulation layer is filled castable, the erosion layer is built by laying bricks or stones for some agalmatolite bricks and is formed, alabaster silica chamotte is set between every agalmatolite brick, and alabaster silica chamotte thickness is less than 1mm; On bag end erosion layer, air brick and sliding nozzle device are set, sliding nozzle device is comprised of upper lower skateboard, pocket block and porous plug, on upper and lower slide plate, the mouth of a river is set, and the top at the mouth of a river arranges pocket block, at lower skateboard, porous plug is set, the longitudinal direction of porous plug arranges some slits.
Adopting good effect of the present utility model is the characteristics of utilizing agalmatolite brick non-stick steel and slag, and when making it replace vacuum pouring, other High-Alumina liners such as spinelle of tundish used, can prevent effectively that the tundish inwall from adhering to the residue and residual steel in a large number.Simultaneously, replace the basket pouring of stopper rod winding machine with sliding nozzle device, a difficult problem of having avoided stopper rod each to change, at the lower skateboard of slide gate mechanism, porous plug being installed increases refining effect, and a small amount of impurity that adheres on the bag wall is removed from molten steel.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
Fig. 2 is the sliding nozzle device schematic diagram;
Fig. 3 is the porous plug structural representation;
In figure, 1 steel skeleton, 2 heat-insulation layers, 3 corrode layer, 4 air bricks, 5 sliding nozzle devices, 6 porous plugs, 7 lower skateboards, 8 upper slides, 9 pocket blocks, 10 mouths of a river, 11 slits.
The specific embodiment
As shown in the figure: steel skeleton 1 and corrode between layer 3 heat-insulation layer 2 is set, heat-insulation layer 2 is filled castables, corrodes layer 3 for being that 44 agalmatolite bricks are built by laying bricks or stones and formed, and alabaster silica chamotte is set between every agalmatolite brick, and alabaster silica chamotte thickness is less than 1mm; On bag end erosion layer, air brick 4 and sliding nozzle device 5 are set, sliding nozzle device 5 is comprised of upper lower skateboard 8,7, pocket block 9 and porous plug 6, on upper and lower slide plate 8,7, the mouth of a river 10 is set, the top at the mouth of a river 10 arranges pocket block 9, at lower skateboard 7, porous plug 6 is set, the longitudinal direction of porous plug 6 arranges 5 slits 11.
Unwrap when watering when the centre, pull lower skateboard, make the mouth of a river of upper and lower slide plate concentric, reach beginning to the effect of ingot mould pour steel.
Claims (3)
