Description
Technical field
The invention belongs to continuous casting manufacturing technique technical field, is related to a kind of submersed nozzle through cracks detection means and its detection
Method.
Background technology
In continuous casting production process, molten steel enters tundish from wrapping greatly through excessive bag long nozzle, then enters by submersed nozzle
Enter crystallizer, the strand of various sections is formed after cooled and solidified.Submersed nozzle can ensure that casting stream rounding does not scatter, and flow casting
Completely cutting off completely with air prevents from sucking air, also plays insulation.In actual production process due to submersed nozzle itself
The factors such as material, baking state, molten steel, it may appear that the abnormal conditions of submersed nozzle through cracks.After submersed nozzle through cracks
The oxygen in molten steel suction air can be caused to cause molten steel secondary oxidation, crystallizer molten steel surface rolling slag, have a strong impact on strand matter
Amount.
In existing technology, the method for monitoring state of submersed nozzle is mainly reality of the operating personnel by mold liquid level
Border situation is judged.And often submersed nozzle through cracks is in below molten steel face, the integrality of artificial judgment submersed nozzle
Larger error be present, be unfavorable for monitoring slab quality in real time.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the present invention provides a kind of submersed nozzle through cracks detection means and its inspection
Survey method, the problem of can not monitoring submersed nozzle integrality in real time in the prior art is can solve the problem that, is shown by monitoring system
Real time data, you can monitoring submersed nozzle whether through cracks, reduce labor strength, avoid artificial error in judgement, ensure
Slab quality.
The technical solution adopted for the present invention to solve the technical problems is：A kind of submersed nozzle through cracks detection means, bag
Include heat-insulating shield, contact chip, vibrating sensor, signal wire, protection sleeve pipe, binding clasp, data processor, data line, monitoring
System, the heat-insulating shield outside submersed nozzle are connected with the outer wall of protection sleeve pipe, contact chip and protection sleeve pipe inwall
It is in contact；The contact chip is connected with vibrating sensor, is connected between vibrating sensor and data processor by signal wire
Connect；The monitoring system is connected by data line with data processor.
A kind of detection method of submersed nozzle through cracks detection means, its detecting step are：
The first step：Detection means is fixed on outside submersed nozzle；
Second step：The data of monitoring system real-time display detection means transmission；
3rd step：When submersed nozzle is normal, detection data are steady；
4th step：When detection data fluctuate, submersed nozzle integrality is confirmed；
5th step：Stop casting stream cast, detection means is removed.
The protection sleeve pipe is hollow structure, can be passed through cooling air.
The beneficial effects of the invention are as follows：Can solve the problem that can not monitor asking for submersed nozzle integrality in real time in the prior art
Topic, real time data show by monitoring system, you can monitoring submersed nozzle whether through cracks, reduction labor strength, keep away
Exempt from artificial error in judgement, ensure slab quality.

A kind of detection method of the through cracks detection means of submersed nozzle 1, its detecting step are：
The first step：Detection means is fixed on outside submersed nozzle 1；
Second step：The data of the real-time display detection means of monitoring system 10 transmission；
3rd step：When submersed nozzle 1 is normal, detection data are steady；
4th step：When detection data fluctuate, the integrality of submersed nozzle 1 is confirmed；
5th step：Stop casting stream cast, detection means is removed.
The protection sleeve pipe 6 is hollow structure, can be passed through cooling air.
The present invention can solve the problem that the problem of can not monitoring 1 integrality of submersed nozzle in real time in the prior art, pass through monitoring
System 10 show real time data, you can monitoring submersed nozzle 1 whether through cracks, reduce labor strength, avoid artificially sentencing
Disconnected error, ensures slab quality.
