Abstract
A secondary cooling device on the lower port of a mold belongs to the technical field of steel casting equipment and is used for secondary cooling of casting blanks. The secondary cooling device comprises eight spray pipes, wherein the eight spray pipes are distributed around the passage of the casting blanks at the lower port of the mold; the upper ends of the spray pipes are respectively connected with a water inlet communication pipe; the water inlet communication pipe forms an octagonal annular pipeline surrounding the passage of the casting blanks at the lower port of the mold; the lowerends of the spray pipes are respectively connected with a lower support plate; the lower support plate surrounds the octagonal frame of the passage of the casting blanks; and a plurality of nozzle mounting holes are formed on each spray pipe. After being supplied with water, the secondary cooling device can spray water from eight directions including four sides and four corners of the casting blanks so as to significantly improve the secondary cooling effect, thereby remarkably reducing steel leakage after the casting blanks are discharged from the mold, and reducing the crack and rhomboiditydefects of the casting blank. The secondary cooling device has the advantages of simple manufacture, convenient installation, low cost, convenient assembly/disassembly, and excellent secondary coolingeffect.
Description
Technical field
The utility model relates to the cooling device of conticaster crystallizer in a kind of STEELMAKING PRODUCTION, belongs to the cast steel equipment technical field.
Background technology
In the cast steel production process, crystallizer is the important technological equipment of conticaster, after molten steel is diverted to crystallizer by tundish, once cool off by water-cooled copper, homogeneously crystallized one-tenth base shell around the strand, and along with the vibration and the rotation of straightening roller of crystallizer moves downward, go out that copper pipe is laggard goes into the unsupported secondary cooling zone of strand, be called one section of secondary cooling, the strand outside is the base shell of the about 15～20mm of thickness herein, and inside is not solidified molten steel.Need further cooling just can carry out solidifying fully of molten steel, the existing type of cooling is that the strand four sides is by the cooling of four split water bar water sprays, it is even to inhomogeneous cooling around the strand to exist cooling water, cooling effect is bad, and easily bleed-out, strand were prone to defectives such as face crack, casting blank off-square after strand went out crystallizer.For this reason, need design more effectively cooling device, to improve the quality of strand.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of to cooling around the strand evenly, good cooling results, the measured crystallizer end opening of strand cooling back matter secondary cooling apparatus.
The technical scheme that solves the problems of the technologies described above is:
A kind of crystallizer end opening secondary cooling apparatus, it is made up of 8 nozzles, 8 showers are laid around the passage of continuous casting billet at the crystallizer end opening, the upper end of shower is connected communicating pipe with water inlet respectively, the annulus line of intaking communicating pipe interruption-forming 8 limit shapes under crystallizer, pipeline is round the operation passage of strand, and the lower end of shower is connected with lower supporting plate respectively, lower supporting plate is 8 limit shape frames around the strand passage, is arranged with a plurality of nozzle installing holes on each shower.
Above-mentioned crystallizer end opening secondary cooling apparatus, described water inlet communicating pipe the upper surface be connected by bolting with the crystallizer lower flange, the water inlet manifold that crystallizer lower flange hole and secondary cooling apparatus device are passed in the water supply connector of water inlet communicating pipe joins.
Above-mentioned crystallizer end opening secondary cooling apparatus has the blowdown pipe plug opening in the lower end of every shower.
The utility model is installed in crystallizer end opening place, can spray from eight directions of four faces and four angles of strand after the water flowing, the secondary cooling effect obviously improves, bleed-out obviously reduced after strand went out crystallizer, slab surface crack, off-square defective obviously reduce, have make simple, easy for installation, cost is low, convenient disassembly, advantage such as quick, the secondary cooling that strand is gone out the crystallizer end opening has produced good effect.

The specific embodiment
Show among Fig. 1, the utility model is the octahedral spray crystallizer secondary cooling apparatus that simultaneously strand is sprayed, this device is a weldment, water supply connector 5 is connected communicating pipe 2 with the octagon water inlet, the diverse location on eight limits by water inlet communicating pipe 2, divide downwards to pick out 8 showers 1 that angle is different, shower 1 all adopts 50 square tubes, shower 1 and 32 nozzle installing holes 4 of layout on water inlet communicating pipe 4.
Fig. 2,3,4 shows, the different shower of 8 angles of this device is 11 1 of extrados showers, 12 two of outer arc angle showers, 13 two of side cambered surface showers, 14 two of interior arc angle showers, 15 two of intrados showers, 8 shower end openings all are connected with 8 limits of octagonal lower supporting plate 3, on lower supporting plate 3, leave 8 blowdown pipe plug openings 6, plug is installed, spray equipment is carried out blowdown with convenient with shower 1 corresponding position.
Fig. 5,6 shows that this device is installed in crystallizer end opening place, with set bolt 9 this device and crystallizer lower flange 8 is fixed, and crystallizer lower flange hole is passed in the water supply connector 5 of this device, and joins with the water inlet manifold of this device.After the water flowing, extrados shower 11, outer arc angle shower 12, side cambered surface shower 13, interior arc angle shower 14, intrados shower 15 can spray from 4 faces of strand and 8 directions at 4 angles.
Before not adopting the utility model, because the secondary cooling effect is bad after going out crystallizer, strand goes out breakout ratio height behind the crystallizer, and strand is prone to defectives such as face crack, off-square.Split water bar is changed frequent, and the use cost height has expended lot of manpower and material resources.
After adopting the utility model, secondary cooling obviously improved after strand went out crystallizer, and strand leaks after going out crystallizer Steel obviously reduces, and slab surface crack, off-square defective obviously reduce. The utility model is made simple, and is easy for installation, Cost is low, has simultaneously convenient disassembly, the characteristics such as quick, and the secondary cooling that strand is gone out the crystallizer end opening has produced excellent Good effect.
