Abstract
It is an aspect of the invention to provide a kind of continuous small-billet casting method, the technical scheme for solving its technical problem uses wide-angle, the water-cooled nozzle of big yield for the cold house end of billet caster two, and the jet angle of the water-cooled nozzle is 75 ° to 85 °；The standard state water of the water-cooled nozzle is 40 liters/min to 50 liters/min；Wherein, the specification limit of billet caster is R6 130 × 130mm of rice arc to 150 × 150mm of R10 rice arcs.Another aspect of the present invention is to provide billet caster used in a kind of above method, and the jet angle of water-cooled nozzle used in the cold house end of billet caster two is 75 ° to 85 °；The standard state water of the water-cooled nozzle is 40 liters/min to 50 liters/min.
Description
Technical field
The invention belongs to casting field, and in particular to the cooling device and one that a kind of continuous casting process for billets and the technique use
Kind conticaster.
Background technology
In the prior art, the billet caster strand low multiple quality of continuous casting process for billets, especially 150 × 150mm
Lifting, the new end type of cooling is mainly taken, end nozzle sets wide-angle to cool down, and not only reduces the stifled of end nozzle
Plug rate, while the uniformity of end cooling is improved, strand even phenomenon of inhomogeneous cooling caused by sideslip in two cold houses is reduced, is led to
After crossing it was verified that being cooled down using end wide-angle, strand low multiple quality is obviously improved, and the frequency of shrinkage cavity occurs and grade is big
Amplitude reduction.
Current domestic billet caster is in the setting of two cold house's nozzles by the way of up big and down small, in order to
Strand cooling strong up and weak down in two cold houses is realized, from ensuring that Inner Quality of Billet is stable, therefore, in order to make strand cold two
The cooling of end is small, generally uses angle and the less nozzle of standard state water in two cold ends, and with angle and standard state water
Reduction, the aperture of nozzle core constantly reduces, and spray nozzle clogging rate gradually increases with respect to two cold-zone tops, simultaneously, small billet
Conticaster is easily present than more serious strand deviation phenomenon, and when strand sideslip, cooled region is offset, and thus causes strand to go out
The internal soundness problems such as now serious shrinkage cavity, segregation.
The content of the invention
In view of the above the shortcomings that prior art, it is an object of the invention to provide a kind of continuous casting process for billets and it is somebody's turn to do
The cooling device and a kind of conticaster that technique uses, for solving above mentioned problem of the prior art.
In order to achieve the above objects and other related objects, it is an aspect of the invention to provide a kind of continuous small-billet casting side
Method, the technical scheme for solving its technical problem are sprayed for the cold house end of billet caster two using wide-angle, the water cooling of big yield
Mouth, the jet angle of the water-cooled nozzle is 75 ° to 85 °；The standard state water of the water-cooled nozzle is 40 liters/min to 50 liters/min
Clock；Wherein, the specification limit of billet caster is R6 130 × 130mm of rice arc to 150 × 150mm of R10 rice arcs.
Preferably, the specification of billet caster is 150 × 150mm of R10 rice arcs；The water-cooled nozzle spray angle is
80°；The standard state water of the water-cooled nozzle is 45 liters/min.
Another aspect of the present invention is to provide billet caster used in a kind of above method, the continuous small-billet casting
The jet angle of water-cooled nozzle used in the cold house end of machine two is 75 ° to 85 °；The standard state water of the water-cooled nozzle be 40 liters/
Minute is to 50 liters/min.
The cooling of caster two cold room of the present invention end compares water cooling using wide-angle, the water-cooled nozzle of big yield, standard state water
Nozzle improves 27%, and jet angle brings up to 80 ° or so by 60 °, increases the area coverage of cooling water, strand is carried out excessive
Covering, the cooling overlay area of each nozzle 35% exceeds strand edge in the vertical direction of strand walking, is sprayed using nozzle
The central area cooling strand of water smoke, it is more uniform to cool down the regional area of covering, can be complete when sideslip 30mm occurs in strand
All standing edge, because nozzle excessively covers, the cooling water inflow received in the vertical direction of actual strand strand walking only has
The 35% of specified rate, therefore meet the requirement of strand end weak cold but, simultaneously as nozzle type selecting is larger, mouth core is larger, it is not easy to
Occur blocking now.
