Description
Technical field
The utility model relates to converter structure technical fields, more particularly to a kind of quick-installed fine and close converter tapping
Mouthful.
Background technique
Converter taphole is the unique passage that molten steel is entered ladle by converter, when tapping, to bear high-temperature molten steel, clinker
Friction is washed away and oxidative attack, causes the tapping hole service life very low.In order to not influence the production cycle, steel quality and production are not influenced
Stability needs constantly to repair and replace tapping hole.Existing tapping hole be mechanical pressing and tar magnesia vibration moulding, and
Using masonry way, exists and the deficiencies of time-consuming, production efficiency is low, tapping hole abrasion resistance is poor, service life is short is installed.
Summary of the invention
The quick-installed fine and close converter tapping of one kind that in order to overcome the deficiencies of the prior art, the utility model provides
Mouthful.Abrasion resistance is strong, long service life, quick and easy for installation, high production efficiency.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of quick-installed fine and close converter taphole, including steel pipe, magnesia carbon brick refractory material layer, Martin's layer of sand and method
It is blue；The magnesia carbon brick refractory material layer is wrapped in outer surface of steel tube, and magnesia carbon brick refractory material layer is formed using static pressure mode；Converter
Insulating brick-layer is located at outside magnesia carbon brick refractory material layer, is filled out between converter insulating brick-layer and magnesia carbon brick refractory material layer by Martin's sand
It fills and is compacted, form Martin's layer of sand, converter steel structure is located at outside converter insulating brick-layer；Flange is fixed in steel pipe bottom, tapping
Mouth is fixed in converter by flange and converter steel structure connection.
Compared with prior art, the utility model has the beneficial effects that
(1) magnesia carbon brick refractory material layer is formed using static pressure mode, and tapping hole compactness extent is high, and the porosity is low, and structure is equal
Even, abrasion resistance is strong, long service life；
(2) tapping hole is by flange and converter steel structure connection, and then is fixed in converter, and installation process is simple and fast,
High production efficiency.
Detailed description of the invention
Fig. 1 is the utility model structural representation sectional view.
In figure: 1- steel pipe 2- magnesia carbon brick refractory material layer 3- Martin layer of sand 4- converter insulating brick-layer 5- flange 6- turns
Furnace steel construction
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of quick-installed fine and close converter taphole include steel pipe 1, magnesia carbon brick refractory material layer 2,
Martin's layer of sand 3 and flange 5.
Magnesia carbon brick refractory material layer 2 is wrapped in outer surface of steel tube, and magnesia carbon brick refractory material layer 2 is formed using static pressure mode.
High with the molding tapping hole compactness extent of static pressure mode, the porosity is low, and structure is uniform, and abrasion resistance is strong.
Converter insulating brick-layer 4 is located at outside magnesia carbon brick refractory material layer 2, converter insulating brick-layer 4 and magnesia carbon brick refractory material
It is filled and is compacted by Martin's sand between layer 2, form Martin's layer of sand 3, converter steel construction 6 is located at outside converter insulating brick-layer 4.
Flange 5 is vertically fixed in 1 bottom of steel pipe, and tapping hole is connect by flange 5 with converter steel construction 6, and then is fixed on
In converter.Using flanged joint, keep installation process more convenient, it is time saving and energy saving.
The utility model magnesia carbon brick refractory material layer 2 is formed using static pressure mode, and tapping hole compactness extent is high, the porosity
Low, structure is uniform, and abrasion resistance is strong, long service life；Tapping hole is fixed on by flange 5 and converter steel structure connection 6
In converter, installation process is simple and fast, has saved artificial masonry cost, has improved production efficiency.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
