Description
Technical field
The utility model relates to the lower mouth of a river used when a kind of metallurgical technology field steel-making industry continuous casting is produced.
Background technology
Slide gate nozzle is mainly used in the steel flow control system of ladle and tundish, is one of the chief component of non-oxidation continuous casting protection system.Slide gate mechanism is the passage that molten steel enters tundish, rise and control steel temperature, regulate the effect of steel stream, because controllability is good, security is high and developed rapidly, steel ladle sliding water gap is primarily of filling pipe end, sliding plate brick and lower mouth of a river composition, the lower mouth of a river is the passage of stream steel, under the impact of stream steel, the inner core at the lower mouth of a river easily damages, therefore, for convenience of changing, saving resource, the zirconium core split that penetrating connecting hole is generally offered by brick body and Qi Nei in the existing lower mouth of a river forms, and the zirconium core of this structure easily comes off under the impact of stream steel in brick body, production accident is caused to occur.Brick body is when toasting, the gas that moisture and brick body produce when drying is difficult to exhaust, therefore have impact on intensity and the quality of brick body, moreover after adding and being stained with zirconium core, the moisture of bonding mud also will soak into and zirconium core lower end through brick body, plane bonding part is got rid of, and as brick body poor air permeability, is easy to cause brick body dry not dry or produce the waste adding long-time and electric energy.
Utility model content
For solving the problem, the purpose of this utility model is to provide the lower mouth of a river, has both been convenient for changing zirconium core, also makes zirconium core not easily come off in brick body.
The utility model for achieving the above object, be achieved through the following technical solutions: the lower mouth of a river, comprise brick body, fixing hole is offered in the middle part of brick body, zirconium core is set in fixing hole, zirconium core external wall of upper portion both sides arrange vertical slide block, chute is offered in both sides, fixing hole top, the length of chute is less than the degree of depth of fixing hole, chute matches with slide block, zirconium in-core offers penetrating connecting hole, brick body external wall of upper portion circumferentially evenly arranges several boss, brick body external wall of upper portion both sides arrange holder rank, holder rank are connected with boss, in the middle part of brick body, periphery arranges iron-clad, iron-clad upper inside wall is connected with holder bottom, rank outer wall, described iron-clad outer wall arranges several through hole.
For realizing the purpose of this utility model further, can also by the following technical solutions: described fixing hole is taper hole, and the lower end radii R1 of fixing hole is less than the upper end radius R 2 of fixing hole, zirconium core is cone cylinder, and the lower end radii of zirconium core is less than the upper end radius of zirconium core; Described connecting hole can be the open-work of the arbitrary shape such as taper hole, straight hole.
The utility model has the advantage of: the utility model iron-clad adds hole, ensure has airing function in lower nozzle brick body bake process, and the protection of iron-clad is by the chute surface of upper table surface, and to mouth of a river mouth cone portion end, inclusion body is very large.Dry when the mouth of a river uses at the scene, instantaneous touch there will not be to high temperature and bursts phenomenon, avoids causing the generation of wearing steel and causing production accident.Brick body is set, fixing hole in order to hold zirconium core is set in brick body, and offer chute in both sides, fixing hole top, both sides, zirconium core top arrange the slide block matched with chute, lead when this structure has both facilitated zirconium core to install, zirconium core both sides are made again to be fixed on by slide block on the chute of brick body, because stream steel impacts zirconium core from top to bottom, therefore, this structure makes zirconium core fixing-stable, avoid coming off and cause production accident to occur, be convenient for changing again.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is the top view of Fig. 1.
Reference numeral: 1 brick body 2 zirconium core 3 iron-clad 4 connecting hole 5 boss 6 through hole 7 holds in the palm rank 8 chute 9 slide block 10 fixing hole.
Detailed description of the invention
The lower mouth of a river, as shown in the figure, comprise brick body 1, fixing hole 10 is offered in the middle part of brick body 1, zirconium core 2 is set in fixing hole 10, zirconium core 2 external wall of upper portion both sides arrange vertical slide block 9, chute 8 is offered in both sides, fixing hole 10 top, the length of chute 8 is less than the degree of depth of fixing hole 10, chute 8 matches with slide block 9, penetrating connecting hole 4 is offered in zirconium core 2, brick body 1 external wall of upper portion circumferentially evenly arranges several boss 5, brick body 1 external wall of upper portion both sides arrange holder rank 7, holder rank 7 are connected with boss 5, in the middle part of brick body 1, periphery arranges iron-clad 3, iron-clad 3 upper inside wall is connected with holder bottom, rank 7 outer wall.This structure arranges the fixing hole 10 in order to hold zirconium core 2 in brick body 1, and offer chute 8 in both sides, fixing hole 10 top, both sides, zirconium core 2 top arrange the slide block 9 matched with chute 8, guiding when this structure had both facilitated zirconium core 2 to install, makes again zirconium core 2 both sides be fixed on the chute 8 of brick body 1 by slide block 9, because stream steel impacts zirconium core 2 from top to bottom, therefore, this structure makes zirconium core 2 fixing-stable, and avoiding coming off causes production accident to occur, and is convenient for changing again.For convenience of processing, boss 5 can be integrally manufactured with brick body 1, also can with brick body 1 split manufacture.
For avoiding the apertured defect of iron-clad 3 and departing from brick body 1, cause molten steel leakage, increase steel and smelt danger coefficient, described iron-clad 3 outer wall arranges several through hole 6.This structure can make brick body 1 and iron-clad 3 inwall be closely as one, and avoids causing molten steel leakage, increases steel and smelts danger coefficient.This structure can also ensure there is airing function in lower nozzle brick body bake process.
For making zirconium core 2 fixation further, described fixing hole 10 is taper hole, and the lower end radii R1 of fixing hole 10 is less than the upper end radius R 2 of fixing hole 10, and zirconium core 2 is cone cylinder, and the lower end radii of zirconium core 2 is less than the upper end radius of zirconium core 2.This structure can make up big and down small zirconium core 2 cannot depart from from brick body 1 bottom, and avoiding coming off causes production accident to occur, and is convenient for changing again.
Arrange flow and the diameter of the outflow of stream steel for convenience, described connecting hole 4 can be the open-work of the arbitrary shape such as taper hole, straight hole.
The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The technology contents of the not detailed description of the utility model is known technology.
