But continuous casting billet temperature after cutting finishing is mostly 700 DEG C ~ 800 DEG C and is in phase change zone, strand is the longest in this phase change zone time more is easily caused intergranular precipitation so that intergranular adhesion dies down, and strand formation of crack produces in a large number, hot charging crackle easily occurs.
Utility model content
The purpose of this utility model is to provide and a kind of can quickly cool down online strand, reduces intergranular and separates out, the online fast cooling device of strand of crystal grain thinning.
This utility model adopts the following technical scheme that
A kind of online fast cooling device of strand, it includes the lower house that aqua storage tank, upper shell are corresponding with upper shell；It is respectively arranged with water injector in described upper shell and lower house；Described water injector is sequentially connected with buffer tank by aqueduct respectively and with water pump and finally connects with aqua storage tank；Described upper shell top is provided with steam collection port；Described steam collection port is connected with aqua storage tank by airduct；It is provided with discharge outlet bottom described lower house；Described discharge outlet is connected with aqua storage tank by reflux line；It is provided with aerator on described airduct；It is provided with reflux pump on described reflux line.
Further, described water injector includes total pipeline and the some arms being parallel to each other connected respectively with total pipeline；Several shower nozzles it are evenly distributed with on described arm；Described total pipeline connects with aqueduct.
Further, described shower nozzle includes the sparge pipe connected with arm and is arranged on two water spray arms of sparge pipe water side；Two described water spray arms are 120 degree of angles respectively with sparge pipe.
Further, described water pump is variable frequency pump, and described variable frequency pump is connected with controller.
The beneficial effects of the utility model are: upper shell and lower house are separately positioned on the upper and lower of roller-way, water injector is positioned at housing, the strand transported on roller-way can be carried out water-spraying control, upper shell can return to aqua storage tank after the steam after gasification is derived and liquefied, and lower house can be by remaining Water Sproading to aqua storage tank.Being additionally provided with buffer tank on aqueduct, buffer tank plays buffering cooling water, adjusts the effect balancing each nozzle cooling water water yield.This device is arranged on continuous casting line, through apparatus for supercooling after strand cutting deburring, by strand being cooled fast to 550 DEG C at water injector, avoids phase change zone, reduces intergranular and separate out, crystal grain thinning, thus reaches to reduce the effect of hot charging crackle.
