Description
Technical field
The present invention relates to continuous casting technology field, more particularly to a kind of secondary cooling apparatus for conticaster.
Background technology
In continuous casting, different product generally corresponds to different secondary cooling schemes, for example, due to middle low carbon steel and
There is difference in the coagulating property of high-carbon steel, so middle low carbon steel is different in the water distribution quantity of secondary cooling section from high-carbon steel, in order to suitable
Different secondary cooling schemes are answered, enterprise generally requires the nozzle shut down and change other models, or is selectively gated off online
Portion nozzle, in view of shutting down the production efficiency for having a strong impact on conticaster, latter approach is used enterprise more.
At present, after line closes the portion nozzle of secondary cooling apparatus, the nozzle of closing by high-temperature continuous casting blank because being dried
It is roasting and temperature is raised, easily there is rubber gasket or sealing ring melts and the problem of plug nozzle, to alleviate this problem, some
Enterprise makes pent nozzle keep low discharge operation, still, and water hour is easily influenceed by cooling water quality in nozzle, is formed
Block or water flowing is not smooth, still can not efficiently solve nozzle and the problem of temperature is too high occur.Therefore, online closing how is avoided
Nozzle temperature too high become those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
In view of this, the invention provides a kind of secondary cooling apparatus for conticaster, the secondary cooling apparatus can
There is the too high problem of temperature in the nozzle for being effectively prevented from closing online, is conducive to extending the service life of nozzle.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of secondary cooling apparatus for conticaster, including for conveying the cooling water supervisor of cooling water, being arranged on institute
State the cooling water branch pipe on cooling water supervisor and be arranged on the nozzle of the cooling water branch pipe end, in addition to：
The protection water being arranged side by side is responsible for the cooling water to be responsible for；
It is arranged on the protection water branch pipe of the protection water supervisor above, with the cooling water branch tube side-by-side, the protection water branch
The length of pipe is more than the length of the cooling water branch pipe, and the end of the protection water branch pipe is bent towards the nozzle, described to protect
The end for protecting water branch pipe is provided with water jet.
Preferably, in above-mentioned secondary cooling apparatus, the end of the protection water branch pipe is bent to form towards the nozzle
The bending angle of bending part is 50 °~70 °.
Preferably, in above-mentioned secondary cooling apparatus, the bending angle is 60 °.
Preferably, in above-mentioned secondary cooling apparatus, the protection water supervisor and/or the protection water branch pipe are stainless steel
Pipe.
Preferably, in above-mentioned secondary cooling apparatus, the protection water supervisor and/or the protection water branch pipe are square
Pipe.
Preferably, in above-mentioned secondary cooling apparatus, in addition to：
The air being arranged side by side is responsible for the cooling water to be responsible for；
It is arranged on the air branch pipe of the air supervisor above, with the cooling water branch tube side-by-side, the end of the air branch pipe
End is connected with the nozzle.
Preferably, in above-mentioned secondary cooling apparatus, the cooling water supervisor, the protection water supervisor and the air master
Pipe is integrally welded.
Preferably, in above-mentioned secondary cooling apparatus, the bottom of the cooling water supervisor and/or the protection water supervisor are set
It is equipped with discharging valve.
It can be seen from preceding solution, the present invention be provided with protection water supervisor, and protection water supervisor on set with it is cold
But the protection water branch pipe of water branch tube side-by-side, because the length for protecting water branch pipe is more than the length of cooling water branch pipe, and protects water branch
The end of pipe is bent towards nozzle, and the end of protection water branch pipe is provided with water jet, so it is secondary to protect water branch pipe to spray to water
The nozzle of cooling device, to the nozzle formation cooling protection closed online, it is to avoid nozzle temperature is too high, while protecting the spray of water branch pipe
The water gone out will not reach continuous casting billet, thus on continuous casting billet secondary cooling scheme be smoothed out will not produce influence.
