Specific embodiment
In order to better understand the present invention, with reference to the accompanying drawing with the embodiment content that the present invention is furture elucidated, but this
The content of invention is not limited solely to the following examples.
Fig. 1 is casting blank crack line figure caused by non-uniform spraying, although it will be seen from figure 1 that underbead crack is very serious,
But it is smaller and short on pattern, there is segregation phenomena among crackle, hence it is evident that for crackle caused by process of setting thermal stress.This kind is split
Line can the serious quality and performance for influencing steel billet.In traditional aerial fog nozzle steel alloy casting machine, as the raising of pulling rate is this
Crackle is very common；In the full (operating) water nozzle design of high pressure, with regard to 150*150 small billet, once straight carbon steel pulling rate is greater than 3.4m/min, product
Kind pulling rate is greater than 2.5m/min, and this middle crack is more common in slab, and is difficult to completely eliminate.
Fig. 2 is the traditional two cold water spray system schematic of small billet variety steel casting machine for leading to the above casting blank crack line, spray
Mouth uses the ellipse of small water or bores nozzle entirely, and due to the limitation of bleed type, nozzle footprint is smaller, on slab
The spray spot for forming ellipse is not overlapped each other, as shown in figure 3, there is water spray area and the area that do not spray water, this necessarily brings cold
But unevenness.In low pulling rate, slab temperature is lower, and this uneven bring temperature difference is also little, splits to slab inside
Having an impact for line is smaller, once pulling rate improves, slab temperature is improved, and the temperature difference in water spray area and the area that do not spray water increases rapidly, different
Normal thermal stress occurs, and leads to the generation of crack of billet.
It can also be seen that the fixation of traditional spraying rack is closely related with carrying roller position from Fig. 2, spraying rack is located at two
On carrying roller, the fixed equipment of such spraying rack is simpler and easy to accomplish, but leads to a section spraying rack or spray tube very
Long, generally in 2m or more, even up to 2.8m, than heavier, installation is not easy to spraying rack own wt, simultaneously because spraying rack
Too long, after nozzle spray, decline of pressure is obvious, it may appear that spraying rack upper end nozzle is bad due to the inadequate spraying effect of pressure
The case where, or even the case where do not spray water, so that all cannot achieve the continuous of the slab on throwing direction in a spraying rack
It is cooling.
To solve the above problems, the technical solution adopted by the present invention are as follows: as shown in figure 4, being drawn for billet caster height
The two cold water spray equipment that fast-growing produces include more piece spraying rack 1, and spraying rack 1 described in every section includes more spray tubes 2, the spray tube
2 four directions all around that are symmetrical and being evenly provided on continuous casting billet.Aerial fog nozzle 3 is provided on the spray tube 2, it is described
Central axes of the water outlet normal of aerial fog nozzle 3 perpendicular to continuous casting billet.The two cold water sprays equipment it is contrary with throwing one
End, the front and rear edges for the adjacent spray spot 4 that the aerial fog nozzle 3 is formed on continuous casting billet is all overlapped, adjacent two aerosol
Nozzle 3 is sprayed onto the water on continuous casting billet surface in continuous arrangement.The height of the aerial fog nozzle 3 away from continuous casting billet along throwing direction gradually
Reduce, so that the front and rear edges along the adjacent spray spot 4 in throwing direction is overlapped from all overlapped parts that becomes, protects simultaneously
The overlay area for demonstrate,proving spray spot 4 in the slab width direction vertical with throwing direction is gradually reduced.
The aerial fog nozzle 3 is flat or rectangle aerial fog nozzle, and round and smooth irregular in quadrangle is formed on continuous casting billet
Rectangle sprays spot 4, as shown in figure 5, the short side of two adjacent rectangles spray spot 4 coincides completely or partially.The aerial fog nozzle 3
It is wide to spray angle up to 85~110 °, it is narrow to spray angle be 20~40 °, it is described wide to spray angle and narrow to spray angle
It can be changed within the above range by controlling hydraulic pressure, hydraulic pressure can be 0.8~2.0MPa.The aerial fog nozzle 3 is with width to injection
Angle is evenly arranged on the spray tube 2 along throwing direction, and the distance between two adjacent aerial fog nozzles 3 are 350~500mm.Often
The aerial fog nozzle 3 of same or different quantity can be set on the spray tube 2 of a 1 four direction of spraying rack.Due to entirely spraying
Frame has certain radian, and the quantity of aerial fog nozzle 3 is few on the spray tube 2 of the interior outer arc in knee, spacing is big, and is located at
The quantity of aerial fog nozzle 3 is more on the spray tube 2 of 1 left and right side of spraying rack, spacing is small.
The height of the aerial fog nozzle 3 away from continuous casting billet surface is 200~300mm, and is gradually reduced along throwing direction.This is
Because the temperature of continuous casting billet gradually lowers along throwing direction, the steel billet supercooling of 4 overlapping of spot is sprayed in order to prevent, described two
Adjacent spray spot 4 only in the middle section of the short side overlapped, corner parts of the cold water spray equipment along throwing direction one end
It is no longer overlapped, and the overlay area that spot 4 is sprayed in the slab width direction vertical with throwing direction is gradually reduced.So can cast
After base pulling rate improves, preferable cooling uniformity is still kept, minimum thermal stress is generated, to avoid the occurrence of caused by thermal stress
Middle crack.
Fig. 4 and Fig. 6 respectively illustrates two kinds of fixed forms of spraying rack 1.As shown in figure 4, the fixed point of upper section spraying rack
For a and b, a is taken root from pedestal, and b is located at spraying rack upper right side, but is taken root still from the identical pedestal of same a, and a hook housing is generated,
Fixed frame as b.The fixed point a and b of spraying rack are taken root from adjacent pedestal in Fig. 6, are all located at the lower section of spraying rack,
A is located at below spraying rack entrance, and b is located at spraying rack outlet lower section.This two kinds of structures design fixation and tradition so that spraying rack 1
Carrying roller decoupling makes that single 2 length of spray tube is shorter and length facilitates adjustings using more flexible fixed form, this design is very well
Solve the problems, such as that spraying rack upper nozzle pressure is low.Even if using 2 two spraying racks of spraying rack public one of this form
