Description
Technical field
The utility model belongs to the checking tool of steel plant continuous casting middle water containing opening centering, particularly a kind of continuous casting production
The checking tool of mouth of a river centering.
Background technology
Continuous casting is typically all poured into a mould by the way of stopper rod flow control+middle water containing opening at present.Continuous casting process
In, because the resistance to material of middle water containing opening constantly corrodes, normal cast is not only influenceed, and occur that steel is lost in the phenomenon of control, scene
Extreme temperatures, human users are difficult, easily cause production accident.Therefore, need to enter middle water containing opening during continuous casting
Row periodic replacement, the mouth of a river of replacing must keep centering, if the through hole among filling pipe end and collector nozzle misaligns, it will cause
The production accident that molten steel beam interrupts.
Due to such a feature of pouring, there is the resistance to material erosion in the mouth of a river or mechanism-trouble situation, can all cause mouth of a river steel flow control
Out of control, serious meeting causes equipment or personnel to injure, and easily causes production accident.Therefore, it is necessary to periodically enter to middle water containing opening
Row is changed.The method of former middle water containing opening centering is manually to see whether centering below collector nozzle.Due to existing inside the mouth of a river
Debris, temperature is very high after overbaking, therefore, easily causes surrounding people's scald accident.
It is as follows that tradition changes subject matter existing for middle water containing opening centering test mode：
1st, change the mouth of a river and open wide cast constantly, scene temperature is higher, and sparks fly off molten steel, causes personnel can not be close to operation, meeting
Cause equipment or personnel to injure, easily cause production accident.
2nd, due to being secondary cooling water below crystallizer, the spray of molten steel entry nozzle region of splashing, risk of explosion be present, change the mouth of a river
Check that centering personal security risk is higher.
3rd, normal production operation is influenceed, worker's labor intensity is higher.
4th, break down time is longer, influences conticaster operating rate.
5th, the mouth of a river centering time is longer, influences production cost.
Utility model content
The purpose of this utility model is to provide a kind of checking tool of continuous casting intermediate inlet centering, and its is rational in infrastructure,
It is easy to operate simple, job security can be improved, it is ensured that the accuracy of mouth of a river centering, can prevent steel with remote operation
Water beam interrupts, and can reduce worker's labor intensity, improves operating efficiency.
What the purpose of this utility model was realized in：A kind of checking tool of continuous casting intermediate inlet centering, including even
Casting middle water containing opening is made up of the filling pipe end and collector nozzle to cooperate, and cylindrical centered cover is set in the front end of straight-bar handle
Cylinder, the axis of centring spool is vertical with straight-bar handle, the external diameter of centring spool and the dynamic cooperation of internal diameter at the upper and lower mouth of a river, centered cover
A diameter of 15cm of cylinder, is highly 30cm.
Major design content is as follows：
Mouth of a river centring spool is made by middle water containing opening internal diameter, sleeve external welding handle, by this instrument from the mouth of a river during use
Lower section is stretched into, if filling pipe end and the non-centering of collector nozzle, sleeve will be unable to be fully inserted into the phase, it is necessary to filling pipe end and collector nozzle
Position is adjusted, until sleeve is fully inserted into, then mouth of a river centering is completed, so as to ensure to change the peace of middle water containing opening operation
Full property and human users' stability.
Improvement effect
1st, change the mouth of a river and check that centering situation in the mouth of a river is easy to operate simple, workers ' safety can be ensured with remote operation, reduced
Worker's labor intensity.
2nd, when steel loss control occurs in the replacing mouth of a river, starting hydraulic cylinder a long way off can cut off the mouth of a river and close, ensure to set
Standby or personnel safety, prevent production accident.
3rd, the time of outlet replacing is reduced, conticaster operating rate can be improved.
4th, ensure the accuracy of mouth of a river centering, can prevent molten steel beam from interrupting, ensure the normal continuous production of conticaster, drop
Low production cost.
The utility model is rational in infrastructure, easy to operate simple, realizes remote operation, improves job security, ensures
The accuracy of mouth of a river centering, it is therefore prevented that molten steel beam interrupts, and reduces worker's labor intensity, improves operating efficiency.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure.
Embodiment
A kind of checking tool of continuous casting intermediate inlet centering, as shown in figure 1, including continuous casting intermediate inlet by phase interworking
