Description
Technical field
The utility model relates to a kind of ladle upper nozzle diameter on-line measurement tools, belong to technical field of metallurgical equipment.
Background technique
Ladle is the molten steel storage transporting equipment in smelter STEELMAKING PRODUCTION.Ladle upper nozzle is that molten steel is flowed out from ladle
Channel, material is Al2O3-C.It is φ 60mm that ladle upper nozzle, which makes diameter (internal diameter), in ladle use process, by
To the erosion of washing away of molten steel, diameter (internal diameter) is increasing.When the mouth of a river, diameter increases to φ 100mm, to guarantee ladle
Using safe, it is necessary to be replaced to the mouth of a river.Therefore, it is necessary to measure online to ladle upper nozzle.Ladle upper nozzle installation
It is refractory material around the mouth of a river in bottom of steel ladle portion, packet bottom is exposed in only filling pipe end outlet.It is also arranged around filling pipe end outlet
There is sled mechanism, operating space is narrow.Liquid steel temperature in ladle is generally in 1600 DEG C, after molten steel flows through filling pipe end, filling pipe end
Through contacting with high-temperature molten steel, temperature generally reaches 1000 DEG C or more.It is influenced by filling pipe end temperature and measurement space, it is general to survey
Amount tool (such as box ruler, vernier caliper) can not carry out on-line measurement to the mouth of a river.Thus it is necessary to invent develop a kind of structure it is simple,
It can be convenient the measuring tool of ground on-line measurement ladle upper nozzle diameter.
Utility model content
Technical problem to be solved in the utility model is that invention develops that a kind of structure is simple, can be convenient ground on-line measurement
The measuring tool of ladle upper nozzle diameter.
The technical solution of the utility model is:
A kind of ladle upper nozzle diameter on-line measurement tool, including insertion end, hold end, measurement end, the insertion end,
It holds end and two measurement ends constitutes trapezoidal sectional shape measurement body.
Ladle upper nozzle diameter on-line measurement tool as described above is labeled with graduation mark between the measurement end.
Ladle upper nozzle diameter on-line measurement tool as described above indicates graduation mark length on the graduation mark.
Ladle upper nozzle diameter on-line measurement tool as described above is labeled with warning line between the measurement end, described
Guard against the limit diameter that line length is ladle upper nozzle.
Ladle upper nozzle diameter on-line measurement tool as described above, the warning line length are the limit of ladle upper nozzle
Diameter.
Ladle upper nozzle diameter on-line measurement tool as described above, the angle between two measurement ends is 25-35
Degree.
Ladle upper nozzle diameter on-line measurement tool as described above, the insertion end hold end and two measurement end structures
It is antiparallelogram cross sectional shape at trapezoidal sectional shape measurement body.
Ladle upper nozzle diameter on-line measurement tool as described above, the insertion end hold end and two measurement end structures
It is right-angled trapezium cross sectional shape at trapezoidal sectional shape measurement body.
Ladle upper nozzle diameter on-line measurement tool as described above, the insertion end hold end and two measurement end structures
It is 10-20mm at trapezoidal sectional shape measurement body thickness.
Ladle upper nozzle diameter on-line measurement tool as described above, the measurement end are processed into chamfering, and chamfering length is
1-2 mm。
The beneficial effects of the utility model are:
The present apparatus solves the immeasurable problem of filling pipe end diameter under high temperature, small space environment, realizes ladle
Filling pipe end diameter on-line checking realizes measuring tool and matches with filling pipe end outlet round sideline contact point, improves the mouth of a river
The accuracy of diameter measurement.This measuring tool structure is simple, easy to use.By adjusting relative dimensions, it can be used for different-diameter
The environment of measurement and general measure tool measurement difficulty.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the utility model right-angle cross-section shape main view；
Fig. 4 is the utility model usage state diagram；
Mark in figure as follows: insertion end 1, holding end 2, graduation mark 3, measurement end 4, warning line 5, collector nozzle 6, collector nozzle go out
Mouth 7.
Specific embodiment
In conjunction with attached drawing, the embodiments of the present invention are described as follows:
A kind of ladle upper nozzle diameter on-line measurement tool, including insertion end 1, holding end 2, measurement end 4, the insertion end
1, it holds end 2 and two measurement ends 4 constitutes trapezoidal sectional shape and measure body, be labeled with graduation mark 3, graduation mark 3 between measurement end 4
Upper mark graduation mark length, warning line 5 is labeled between measurement end 4, and 5 length of warning line is the limit diameter of ladle upper nozzle
100mm.Angle between two measurement ends 4 is 30 degree.Insertion end 1 holds end 2 and two composition trapezoid cross section shapes of measurement ends 4
It is antiparallelogram cross sectional shape that shape, which measures body,.The insertion end holds end and two measurement ends composition trapezoidal sectional shape measurements
Body thickness is 15mm.Measurement end is processed into chamfering, and chamfering length is 1.5mm.
Before measuring the mouth of a river, the related accessory being assembled together with ladle upper nozzle 6 is removed, exposes filling pipe end outlet 7,
And 6 inner cavity of filling pipe end is cleaned out.Insertion end 1 is inserted into from filling pipe end outlet 7 and is stuck in filling pipe end 6, filling pipe end is read
