Description
Technical field
This utility model relates to a kind of for pouring into a mould the apparatus for pouring that tundish permanent layer uses, and belongs to steel-making tundish technical field of auxiliary equipment.
Background technology
The current commonly used working lining of the resistance to material of tundish adds the knot tying fashion of permanent layer, and it is integrated poured that permanent layer mostly is high alumina castable, can Reusability under conditions of impaired area is less；Working lining is usually magnesium dry-type stock or coating, and service life was from several hours to tens hours.The consumption of the damage of the resistance to material of the tundish predominantly resistance to material of working lining, and the resistance to material of working lining uses the difference of condition due to each position, damage degree difference is the biggest.The erosion of tundish top molten steel, coverture and air contact interface material resistance to working lining is especially serious, and bottom bottom and bag, position is corroded lighter.After tundish lining resistance to material structure and use, erosion condition is shown in Fig. 1.
The permanent layer bag tire that generally cast liner in dundish uses uses and simplifies design, sees Fig. 2, is not i.e. distinguish between the knotting thickness of bag tire top and the bottom, causes the knotting thickness of working lining also to reach unanimity at upper and lower position.And in actual use, the resistance to material top and the bottom damage degree difference of liner in dundish is very big, causes liner in dundish bottom relatively light owing to corroding, there is the biggest function superfluous.And the resistance to material of this part is owing to recycling difficulty, cause the biggest material waste.It is therefore desirable to the bag tire using cast tundish permanent layer improves, to extend the use time of liner in dundish.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bag tire pouring into a mould tundish permanent layer, this bag tire can change the shape of tundish permanent layer and working lining contact surface, and then make the effective thickness of liner in dundish top and the bottom produce change, the use time making liner in dundish resistance to material top and the bottom reaches consistent, to extend the overall use time of liner in dundish, reduce the consumption of the material of resistance to material.
The technical scheme solving above-mentioned technical problem is:
A kind of bag tire pouring into a mould tundish permanent layer, it includes that metal cabinet, lifting hanger, liner gusset horizontal bar, liner gusset erect muscle, metal cabinet is made up of base plate and sidewall, liner gusset horizontal bar and liner gusset erect muscle in the inner chamber of metal cabinet, it is connected with base plate and the sidewall weld of metal cabinet respectively, lifting hanger is welded on the corner of metal cabinet upper end, its improvements are, the bottom of four sidewalls of metal cabinet is respectively to metal cabinet inner chamber indentation, and the lower flat of the sidewall after indentation is parallel with the upper plane of sidewall.
The bag tire of above-mentioned cast tundish permanent layer, the bottom of four sidewalls of described metal cabinet matches to the difference of the distance of metal cabinet inner chamber indentation with liner in dundish top and the bottom depth of erosion, and the peak at four sidewall indentation positions matches with the lower position of pouring basket liquid level fluctuation range.
The bag tire of above-mentioned cast tundish permanent layer, the side wall upper part of described metal cabinet is connected with there being transition angle at the indentation of bottom, and transition angle is between 45～60 °.
The beneficial effects of the utility model are:
Four lower sidewall of bag tire metal cabinet of the present utility model are respectively to metal cabinet inner chamber indentation, make the top outward expansion of the tundish permanent layer after cast, after working lining knotting, the thickness on the top of working lining is more than the thickness of bottom, during standing molten steel corrosion, the use time of working lining upper and lower reaches unanimity, the resistance to material in working lining bottom is made to be fully utilized, extend the overall use time of liner in dundish, decrease the consumption of the material of resistance to material, significantly reduce production cost.

In figure, labelling is as follows: metal cabinet 1, lifting hanger 2, liner gusset horizontal bar 3, liner gusset erect muscle 4, sidewall 5, base plate 6, tundish 7, permanent layer 8, working lining 9, pouring basket liquid level 10, slag line 11.
Detailed description of the invention
Fig. 1 shows, uses working lining 9 to add the knot tying fashion of permanent layer 8 in the inclusion of tundish 7, and the resistance to material of working lining 9 uses the difference of condition due to each position, and damage degree difference is the biggest.The erosion of tundish top molten steel, coverture and air contact interface material resistance to working lining 9 is serious, and bottom bottom and bag, position is corroded lighter.
Fig. 2 shows, the structure of existing tundish permanent layer bag tire includes that metal cabinet 1, lifting hanger 2, liner gusset horizontal bar 3, liner gusset erect muscle 4.Metal cabinet 1 is made up of base plate 6 and sidewall 5, and liner gusset horizontal bar 3 and liner gusset erect muscle 4 in the inner chamber of metal cabinet 1, and base plate 6 and sidewall 5 with metal cabinet 1 are welded to connect respectively, and lifting hanger 2 is welded on the corner of metal cabinet 1 upper end.
Fig. 3,4,5 show, this utility model is improved on the architecture basics of existing tundish permanent layer bag tire, its improvements are, the bottom of four sidewalls 5 of metal cabinet 1 is respectively to metal cabinet 1 inner chamber indentation, and the lower flat of the sidewall 5 after indentation is parallel with the upper plane of sidewall 5.
Fig. 3,4,5 show, the bottom of four sidewalls 5 of metal cabinet 1 matches to the difference of distance h of metal cabinet 1 inner chamber indentation with the working lining 9 top and the bottom depth of erosion of tundish 7, the peak at four sidewall 5 indentation positions matches with the lower position of pouring basket liquid level 10 fluctuation range, and its height is H.
Fig. 3,4,5 show, sidewall 5 top of metal cabinet 1 is connected with there being transition angle a at the indentation of bottom, and transition angle a is between 45～60 °.
Fig. 6 shows, this improvement makes the top outward expansion of the permanent layer 8 of the tundish 7 after cast, after working lining 9 knotting, the thickness on the top of working lining 9 is more than the thickness of bottom, and during standing molten steel corrosion, the use time of working lining 9 upper and lower reaches unanimity, the resistance to material in working lining 9 bottom is made to be fully utilized, extend the overall use time of liner in dundish 9, decrease the consumption of the material of resistance to material, significantly reduce production cost.
Use process of the present utility model is as follows:
This utility model is in use, after the permanent layer 8 bag bottom pour mold of tundish 7 is noted, metal cabinet 1 of the present utility model is uniformly coated with one layer of releasing agent, vertically sling with jack lift metal cabinet 1 by lifting hanger 2, put it into and pour into a mould in the tundish 7 wrapping the end, and make the metal cabinet 1 involucrum surrounding with tundish 7 apart from identical as far as possible, it is ensured that permanent layer 8 containment wall consistency of thickness.The permanent layer 8 sidewall casting and constructing of tundish 7 can be carried out according to above-mentioned requirements after metal cabinet 1 is placed.
After permanent layer 8 is poured, vertically sling in tundish 7 metal cabinet 1 with jack lift by lifting hanger 2, then lining 9 knotting it is operated, the thickness bottom making working lining 9 is more thin than top slag lining, during reaching to use, mass erosion is than more uniform purpose, to reduce the consumption of the resistance to material of working lining 9, it is to avoid the waste of the material of resistance to material.
