Description
Technical field
The utility model relates to a kind of immersion type nozzle for slab continuous casting crystallizer Alignment measuring tools, belong to metallurgy industry
Slab caster equipment technical field.
Background technique
Submersed nozzle is one of the functional refractory of most critical in continuous casting, and using effect directly affects continuous casting
Efficiency and billet quality.Submersed nozzle is the only way that molten steel enters crystallizer between tundish and crystallizer, because
This, submersed nozzle plays a part of protecting molten steel, prevents molten steel from contacting a possibility that aoxidizing again with the oxygen in air.
The centering of submersed nozzle or not it is related to the uniformity of crystallizer flow field and solidified shell.However in actual production
In, since, without accurate positioning, the centering of submersed nozzle is all observed by eye, and there are gross errors, very between middle hired car and crystallizer
It is required to technique is unable to reach.Submersed nozzle not will lead to molten steel in mold in and Biased flow phenomenon occur, and forms slag, leads
Cause is mingled with increase, influences slab quality.Make outer arc thickness in solidified shell different simultaneously, or even bleed-out accident occurs.
Utility model content
The utility model aim is to provide a kind of immersion type nozzle for slab continuous casting crystallizer Alignment measuring tool, passes through survey
The centering of submersed nozzle is measured, crystallizer is reduced and slag caused by Biased flow phenomenon occurs, improve slab quality, guarantee solidified shell
Interior outer arc thickness is uniform, prevents the generation of bleed-out accident, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of immersion type nozzle for slab continuous casting crystallizer Alignment measuring tool, comprising measuring scale, handle, measurement plate, straight
Angle set square one and right angle triangle two, handle is fixed in measurement plate, and measuring scale is fixed on one end of measurement plate, right angle trigonometry
Plate one and right angle triangle two are symmetrically fixed on measuring scale, oblique in the bevel edge and right angle triangle two in right angle triangle one
It is constituted between side horn-like.
Apex angle in the right angle triangle one and right angle triangle two is 30 degree.
The handle and measurement plate are arranged vertically.
The measurement plate is rectangle structure.
Handle is held during casting machine is opened and pours and change the mouth of a river using the utility model, two on measuring scale are symmetrical
The right angle triangle one and right angle triangle two of arrangement are inserted into submersed nozzle two sides, if it is possible to which level blocks immersion water
Mouthful, then illustrate that submersed nozzle is to Plays.If submersed nozzle two sides and right angle triangle one and right angle triangle two
In bevel edge between there are gaps, then illustrate the non-centering of submersed nozzle, then according on measuring scale scale appropriate adjustment soak
Enter formula mouth of a river position, until the bevel edge in right angle triangle one and right angle triangle two can level block submersed nozzle.
The beneficial effects of the utility model are: it is existing to reduce crystallizer generation bias current by the centering of measurement submersed nozzle
As caused slag, slab quality is improved, guarantees that outer arc thickness is uniform in solidified shell, prevents the generation of bleed-out accident.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: measuring scale 1, handle 2, measurement plate 3, submersed nozzle 4, right angle triangle 1, right angle triangle 26.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of immersion type nozzle for slab continuous casting crystallizer Alignment measuring tool includes measuring scale 1, handle
2, measurement plate 3, right angle triangle 1 and right angle triangle 26, handle 2 are fixed in measurement plate 3, and measuring scale 1 is fixed on measurement
One end of plate 3, right angle triangle 1 and right angle triangle 26 are symmetrically fixed on measuring scale 1, oblique in right angle triangle 1
It is constituted between bevel edge in side and right angle triangle 26 horn-like.
In the present embodiment, the diameter of submersed nozzle 4 is 120mm, and the width of continuous casting crystallizer for plate billet is 211mm.Plate
Blank continuous casting crystallizer immersible ladle nozzle centering measuring tool, whole to be arranged symmetrically with handle 2 for center line two sides, measurement plate 3
For the rectangle galvanized iron plate of 211mm × 100mm, thickness 2mm-5mm, 1 length of measuring scale is 211mm, and the length of handle 2 is
100mm, measuring scale 1 are fixed in a long side of measurement plate 3, the structure phase of right angle triangle 1 and right angle triangle 26
Together, apex angle α is 30 degree, and the right angle edge lengths of right angle triangle 1 and right angle triangle 26 are 150mm, right angle triangle one
5 and right angle triangle 26 be symmetrically welded at measurement plate 3 equipped with measuring scale 1 on one side on.The bevel edge and right angle of right angle triangle 1
It constitutes horn-like between the bevel edge of set square 26, is matched with submersed nozzle 4,
During casting machine is opened and pours and change the mouth of a river, handle 2 is held, the right angle three that two on measuring scale 1 are arranged symmetrically
Gusset 1 and right angle triangle 26 are inserted into 4 two sides of submersed nozzle, if it is possible to which level blocks submersed nozzle 4, then illustrates
Submersed nozzle is to Plays.If 4 two sides of submersed nozzle with it is oblique in right angle triangle 1 and right angle triangle 26
There are gaps between side, then illustrate the non-centering of submersed nozzle, then according to the scale appropriate adjustment immersion water on measuring scale 1
Mouthful position, until the bevel edge in right angle triangle 1 and right angle triangle 26 can level block submersed nozzle.
