Description
Technical field
The present invention relates to a kind of preventer, specifically converter bleed-out explosion-protection equipment.
Background technology
Domestic converter smelting all adopts more advanced top bottom compound blowing technology at present, and batch also gradually steps up, but body of heater props up
Support mostly employs backing ring supporting form.Converter trunnion ring, as the load carrier of whole body of heater, also undertakes furnace shell, stove in addition to deadweight
The weight such as refractory material, molten steel in shell, structure design is the box-shaped welding structure of big cross section, its internal logical circulating water.But
Molten steel is easy to scaling loss and washes away backing ring once revealing, and makes the mixing of cooling water in molten steel and backing ring, produces heavy explosion.
Content of the invention
It is an object of the invention to provide converter bleed-out explosion-protection equipment, this explosion-protection equipment is to be formed between furnace shell and backing ring
One protecting wall, can block high temperature fluent metal and to the scaling loss of backing ring and wash away, it is to avoid liquid metal contacts with water during bleed-out
The blast causing.So that equipment self-security is improved, prevent bleed-out from setting off an explosion security incident.
The present invention solves its technical problem and is adopted the technical scheme that：Converter bleed-out explosion-protection equipment, its structure includes bottom
Plate and annular guard board, described base plate is a flat board, is vertically connected with annular guard board, backing ring and annular guard board set on base plate
Put, and between the inwall in backing ring and the outer wall of annular guard board, form space；Described backing ring bottom is welded with base plate, described
The top edge of annular guard board is provided with sealing plate, upper end welding, the other end and the backing ring of described sealing plate one end and annular guard board
Upper surface welding, be provided with sealing plate and multiple pour mouth.
Further, described annular guard board side wall is provided with multiple steam vents, a diameter of Φ of described steam vent 10.
Further, the space being formed between backing ring and annular guard board is 50mm, and communicates with pouring mouth.
Further, pour corundum to the space between backing ring and annular guard board and pour by the mouth that pours on annular guard board
Material.
Further, the described mouth that pours is 10.
The invention has the beneficial effects as follows：
1st, this explosion-protection equipment forms protecting wall together by being welded between furnace shell and backing ring of annular guard board, energy during bleed-out
Enough block high temperature fluent metal to the scaling loss of backing ring and to wash away, it is to avoid liquid metal contacts the blast causing with water.Make equipment certainly
Body safety improves, and prevents bleed-out from setting off an explosion security incident.
2nd, reserve in the annular guard board upper end of this explosion-protection equipment and pour mouth, by pouring mouth to the sky between backing ring and backplate
Pour corundum pouring material in gap, form the barricade being made up of refractory material together between body of heater and backing ring, can in bleed-out
Block the possibility that molten steel contacts with cooling water in backing ring.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation that in the present invention, backing ring is nested with annular guard board；
Fig. 3 is the top view of Fig. 1.
In figure：1 backing ring, 2 annular guard boards, 3 sealing plates, 4 pour mouth, 5 base plates, 6 steam vents.
Specific embodiment
With reference to Figure of description, the converter bleed-out explosion-protection equipment of the present invention is described in detail below.
As shown in Figure 1, Figure 2, Figure 3 shows, the converter bleed-out explosion-protection equipment of the present invention, its structure includes base plate 5 and annular guard board
2, described base plate 5 is a flat board, is vertically connected with annular guard board 2, backing ring 1 is nested with annular guard board 2 on base plate 5, and
Form space between the outer wall of the inwall of backing ring 1 and annular guard board 2；Described backing ring 1 bottom is welded with base plate 5, described ring
The top edge of shape backplate 2 is provided with sealing plate 3, upper end welding, the other end and the support of described sealing plate 3 one end and annular guard board 2
The upper surface welding of circle 1, is provided with sealing plate 3 and multiple pours mouth 4.The described mouth 4 that pours is 10.In backing ring and annular shield
The space being formed between plate is 50mm, and communicates with pouring mouth.
The side wall of described annular guard board 2 is provided with multiple steam vents 6, the described a diameter of Φ 10 of steam vent 6.
Corundum pouring material is poured to the space between backing ring and annular guard board by the mouth that pours on annular guard board.
The diameter of annular guard board is determined it is ensured that annular guard board and backing ring set postpone and can reserve certain sky according to backing ring internal diameter
Gap, reserves Φ 10 steam vent on arc, and the discharge being easy to gas when pouring and building material is it is ensured that build the smooth of material.Annular shield
Plate is welded as a whole with base plate, during installation, backing ring is enclosed within outside annular guard board it is ensured that 50mm space, by backing ring bottom and bottom
Plate weld, corundum pouring material, with backing ring upper weld, is then poured into sky by pouring mouth by the sealing plate on annular guard board top
In gap, can pour and complete to pour mouth so that pouring material degree of compaction is guaranteed using mechanical vibration rod and human assistance mode when pouring
Closed.Form protecting wall together between furnace shell and backing ring, the burning to backing ring for the high temperature fluent metal during bleed-out, can be blocked
Damage and wash away, it is to avoid liquid metal contacts the blast causing with water.So that equipment self-security is improved, prevent bleed-out from setting off an explosion
Security incident.
The explosion-protection equipment of the present invention pours corundum pouring material by pouring mouth into the space between backing ring and backplate, in stove
Form the barricade being made up of refractory material together between body and backing ring, cooling water in molten steel and backing ring can be blocked in bleed-out and connect
Tactile possibility.
The above, some principles of the present invention that simply explains through diagrams, this specification is not intended to limit to the present invention
In shown described concrete structure and the scope of application, therefore every corresponding modification being possible to be utilized and equivalent, all
Belong to the apllied the scope of the claims of the present invention.
In addition to technical characteristic described in description, remaining technical characteristic is technology known to those skilled in the art.
