Description
Technical field
This utility model belongs to metallurgy industry Refractory for Ladle field, particularly relates to a kind of refining ladle air brick.
Background technology
Steel ladle bottom argon blowing technology is widely used in external refining.Being blown into argon by being arranged on the air brick of ladle bottom in molten steel, stir molten steel, rapid dispersion, the alloy in molten steel, deoxidizer, desulfurizing agent etc. are added in thawing to, make harmful field trash and gas float, reach refine purpose.Air brick is critical function element, uses condition very harsh, by washing away of stirring molten steel, the intermittently operated etc. of oxygen blast cleaning and rapid heat cycle change.Therefore it is required that breathability, thermal shock resistance, resistance to flaking and non-oxidizability to be got well, compressive resistance is big, and load softening point wants height.
Existing air brick of steel ladle is in use; often there is crackle and burst in the ectosome of air brick and fuse; when the ventilative seam on fuse expands to a certain degree; molten steel will drain to ladle bottom along crackle infiltration; fusing involucrum makes the refractory material of fuse and its underpart depart from ectosome together, causes bleed-out accident.It addition, existing air brick of steel ladle argon to blow out effect unsatisfactory, cause in ladle molten steel to need ladle-to-ladle process or degradation to use.
Summary of the invention
This utility model is intended to overcome the deficiencies in the prior art part to provide a kind of simple in construction, and safety is high, good reliability, and argon blows out refining ladle air brick satisfactory for result.
For solving above-mentioned technical problem, this utility model is realized in.
Refining ladle air brick, serves as a contrast including ectosome, fuse, permeability cell and iron sheet；Described iron sheet lining is coated on fuse, is placed in outer internal；Longitudinally it is provided with several air gap in described fuse；The port of described permeability cell air chamber bottom fuse communicates with air gap；Cyclone sheet it is provided with in described air gap；Outer internal it is provided with metal protection skeleton described；It is provided with refractory material bed course in the bottom of described air chamber.
As a kind of preferred version, the outer wall of iron sheet described in the utility model lining is longitudinally provided with several scrobicular ring.
Further, this utility model is provided externally with iron sheet overcoat what described iron sheet served as a contrast.
This utility model simple in construction, safety is high, good reliability, and argon is blown out satisfactory for result.This utility model can reduce that the molten steel of ladle is ladle-to-ladle does not become, with blowing, the product degradation use problem caused.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection domain of the present utility model is not only limited to the statement of following content.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, ectosome；2, fuse；3, permeability cell；4, iron sheet lining；5, air gap；6, air chamber；7, cyclone sheet；8, scrobicular ring.
Detailed description of the invention
As it is shown in figure 1, air brick of steel ladle, serve as a contrast 4 including ectosome 1, fuse 2, permeability cell 3 and iron sheet；Described iron sheet lining 4 is coated on fuse 2, is placed in ectosome 1；Longitudinally it is provided with several air gap 5 in described fuse 2；The port of described permeability cell 3 air chamber 6 bottom fuse 2 communicates with air gap 5；It is provided with cyclone sheet 7 in described air gap 5；It is provided with metal protection skeleton 9 in described ectosome 1；It is provided with refractory material bed course 10 in the bottom of described air chamber 6.
The outer wall of iron sheet described in the utility model lining 4 is longitudinally provided with several scrobicular ring 8.This utility model is provided externally with iron sheet overcoat 11 described iron sheet lining 4.
This utility model cyclone sheet 7 by being provided with in air gap 5, it may be achieved the eddy airstream of argon, what so can increase substantially argon blows out effect.It addition, serve as a contrast, by iron sheet, several scrobicular rings 8 that 4 outer walls are longitudinally provided with, can prevent fuse 2 from coming off from ectosome 1, it is prevented that the generation of bleed-out accident.This utility model is provided externally with iron sheet overcoat 11 described iron sheet lining 4, can play double shielding function.This utility model is provided with refractory material bed course 10 in the bottom of described air chamber 6 can improve security performance of the present utility model to a certain extent.
It is appreciated that, above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model, and it is not limited to the technical scheme described by this utility model examples of implementation, it will be understood by those within the art that, still this utility model can be modified or equivalent replacement, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
