The utility model discloses simple structure, the security is high, the good reliability, the effect ideal is blown out to the argon gas.
Description
Technical field
This utility model belongs to metallurgy industry Refractory for Ladle field, particularly relates to a kind of air brick of steel ladle.
Background technology
Steel ladle bottom argon blowing technology is widely used in external refining.Being blown into argon in molten steel by being arranged on the air brick of ladle bottom, 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 the harshest, is washed away by stirring molten steel, oxygen blast cleaning and the intermittently operated etc. of 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 bursts with fuse in the ectosome of air brick; 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 molten steel in ladle to need ladle-to-ladle process or degradation to use.
Summary of the invention
Thering is provided a kind of simple in construction in place of this utility model is intended to overcome the deficiencies in the prior art, safety is high, good reliability, and argon blows out air brick of steel ladle satisfactory for result.
For solving above-mentioned technical problem, this utility model is realized in.
Air brick of steel ladle, including: ectosome, fuse, permeability cell and iron sheet lining；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.
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.
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
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.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, including: ectosome 1, fuse 2, permeability cell 3 and iron sheet lining 4；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.
The outer wall of iron sheet described in the utility model lining 4 is longitudinally provided with several scrobicular ring 8.
This utility model, by the cyclone sheet 7 being provided with in air gap 5, can realize the eddy airstream of argon, and 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, prevent the generation of bleed-out accident.
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, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
Claims (1)
