Fall into etc. has remarkable effect, thus is all carried out using this mouth of a river in the sheet billet continuous casting of countries in the world and bloom continuous casting
Casting.According to the requirement of Ferrous Metallurgy, insertion depth of the submersed nozzle in molten steel in mold upper surface is 120-150mm.
But submersed nozzle be inserted in crystallizer liquid steel level hereinafter, and crystallizer mouth size it is smaller, existing measuring device pair
Its insertion depth is difficult to measure, and complicated for operation, time of measuring is long, and measurement accuracy is not also high, of high cost.
Utility model content
The purpose of this utility model is that solve existing measuring device there are drawbacks described above, the utility model provides
A kind of measuring device of continuous casting tundish submersed nozzle insertion depth, the measuring device are the measurement steel of right-angle Z-shaped
Pipe comprising：Hand-held part and insertion section；The hand-held part is horizontally disposed, and the insertion section further comprises：Vertical section and level
Section；The both ends of the vertical section respectively with the hand-held part and the perpendicular relationship of the horizontal segment；The hand-held part and the water
Flat section is mutually parallel.Wherein, the horizontal segment plays the role of hook.
The length of hand-held part is 200-250mm, and the length of vertical section is 400-450mm, and the length of horizontal segment is 50-
100mm；The length of hand-held part is more than the length of horizontal segment.
Scale value, unit mm are carved in the vertical section.
The measuring device is hollow or solid, and a diameter of 3-5mm of measuring device.
The measuring device is made of low-carbon steel material.The horizontal segment and the vertical section are coated with heat safe material
Material, the hand-held part is coated with heat safe material.
When measuring tundish immersed nozzle insertion depth, protective gloves is worn, is held with hand in the measuring device
The measuring device is vertically inserted into the molten steel of crystallizer, the other end of the measuring device by the hand-held part in portion, i.e., horizontal
Section, runs down along mouth of a river wall, when the horizontal segment touch under the mouth of a river along when, touch the measuring device forward, allow survey
The vertical section and submersed nozzle parallel contact of device are measured, and slightly gently puies forward the measuring device upwards, and is stopped 4-5 seconds,
Then it is transferred to from molten steel.It, only 4-5 seconds, will not be by molten steel since the measurement steel pipe and steel contacts time are shorter
It melts.Therefore, after taking out the measuring device, the place with steel contacts has sticked red cold steel.Measuring device is put
It sets 3-5 minutes, after its cooling, the length for sticking cold steel in the measuring device, as submersed nozzle is measured using ruler
Insertion depth；Or according to the scale value in the vertical section directly read the numerical value of insertion depth.
The utility model has the advantage of：
The utility model is simple in structure, easy to operate, and time of measuring is short, cheap, to continuous casting tundish immersion
Mouth of a river insertion depth high certainty of measurement.The utility model can be applicable to any steel plant and be inserted to continuous casting tundish submersed nozzle
Enter depth to measure, have a wide range of application.

Specific implementation mode
As shown in Figure 1, the utility model provides a kind of measurement dress of continuous casting tundish submersed nozzle insertion depth
It sets, the measuring device is the measurement steel pipe of right-angle Z-shaped comprising：Hand-held part 1 and insertion section；1 level of the hand-held part is set
It sets, the insertion section further comprises：Vertical section 2 and horizontal segment 3；The upper/lower terminal of the vertical section 2 is held with described respectively
3 perpendicular relationship of portion 1 and the horizontal segment；The hand-held part 1 is mutually parallel with the horizontal segment 3.Wherein, the horizontal segment 3
Play the role of hook.
The length of hand-held part 1 is 200mm, and the length of vertical section is 400mm, and the length of horizontal segment is 50mm；Hand-held part 1
Length is more than the length of horizontal segment 3.
It is coated with heat safe material in the vertical section 2, and is carved with scale value, unit mm.
The measuring device is hollow or solid, and a diameter of 3-5mm of measuring device.
The measuring device is made of low-carbon steel material.The horizontal segment 3 and the vertical section 2 are coated with heat safe material
