Abstract
Disclosed is an improved structure of a zero-section spray of a tubular crystallizer for a rectangular blank and a cogged ingot. The improved structure is composed of a top flange, an upper flange, a water sleeve, a copper pipe, an outer shell, a lower flange, the zero-section spray, a foot roll device, a sealing piece, connecting bolts and connecting nuts. A middle fixing plate is fixed on the middle portion of an outer ring of the crystallizer. A water inlet pipe and a water return pipe of the crystallizer and a zero-section water inlet pipe are respectively fixed on the middle fixing plate. The zero-section spray is composed of spray pipes and a spray head fixed on the spray pipes. The improved structure is characterized in that the zero-section spray is composed of two sections of L-shaped spray pipes. The two sections of spray pipes are respectively provided with a water inlet. The zero-section water inlet pipe is respectively connected with the water inlets of the two sections of spray pipes. The improved structure conducts improvement based on an existing crystallizer, an annular whole spray pipe is improved to be composed of the two sections of L-shaped spray pipes. If one side is broken, only one side of the spray pipe needs to be maintained. And the spray pipe only needs to be moved out from the side face in the process of maintenance, and thus the improved structure is convenient to maintain, maintaining cost is reduced, and working efficiency of a continuous casting machine is improved.
Description
Technical field:
The utility model relates to continuous casting equipment, rectangular bloom, the bloom crystallizer particularly used in a kind of steel production enterprise conticaster.
Background technology:
Continuous cast mold is the key equipment in the conticaster, and its structural behaviour directly affects production and the quality of continuous casting billet.At present, widely used rectangular bloom during continuous casting is produced, the bloom tube type mold, such as Fig. 1,2, shown in 3, by top flange 1, upper flange 3, water jacket 4, copper pipe 5, shell 6, lower flange 7, zero section spray 8, the compositions such as foot-roller unit 9 and various seal attachment bolt nuts, copper pipe 5 and water jacket 4 are housed in the shell 6, even cooling water seam is shaped in the middle of copper pipe 5 and the water jacket 4, the water jacket spacer flanger is divided into up and down two chambeies with shell 6 simultaneously, upper is backwater cavity, it is down intake antrum, the upper and lower side of shell 6 is equipped with flange and seal, zero section spray and foot-roller unit is equipped with in the lower end, is welded with crystallizer water inlet pipe 62 on the middle fixed head 61, return pipe 63 and zero section water inlet pipe 64(Fig. 2), return pipe communicates with the housing epicoele, water inlet pipe communicates with the housing cavity of resorption, and zero section water inlet pipe directly communicates with zero section spray 8.
As shown in Figure 3, zero section spray 8 is comprised of shower 82 and the spray head 81 that is fixed on the shower 82, and zero section water inlet pipe 64 is the water inlet 641 of logical shower directly, and shower 82 adopts whole polygonized structure, so that behind the continuous casting bleed-out, zero section maintenance Recovery processing difficulty is large.
Summary of the invention:
The purpose of this utility model is defective and the problem that exists for above-mentioned crystallizer, and the improvement structure of the rectangular bloom a kind of easy to maintenance that provides, bloom tube type mold zero section spray.
The technical scheme that the utility model adopts is a kind of rectangular bloom, the improvement structure of bloom tube type mold zero section spray, by the top flange, upper flange, water jacket, copper pipe, shell, lower flange, zero section spray, foot-roller unit and seal, the attachment bolt nut forms, fixed head in the middle of middle part, crystallizer outer ring is fixed with, the crystallizer water inlet pipe, return pipe, zero section water inlet pipe is separately fixed on the middle fixed head, zero section spray is comprised of shower and the spray head that is fixed on the shower, its main points are, zero section spray is comprised of two sections showers that are L-type, two sections showers have respectively water inlet, and zero section water inlet pipe joins with the water inlet of two showers respectively.
The utility model is to improve on the basis of existing crystallizer, the shower that the whole shower of ring-type is modified into two sections L-types forms, and as long as a side damages the one-sided shower of maintenance, and during maintenance as long as shift out from the side, convenient for maintaining has reduced maintenance cost.
The utility model also can be done further improvement, and the arranged on left and right sides of middle fixed head is fixed with respectively a crystallizer water inlet pipe, return pipe.Cooling for the crystallizer upper end has increased a water inlet pipe and return pipe more, has accelerated water intake velocity, and the flowing water of the water inlet pipe of a side is responsible for cooling off crystallizer half in theory, and the uniformity of cooling doubles.
The utility model has the advantage of: adopt split type zero segment structure, make things convenient for accident treatment, improve the conticaster operating rate.Two-way water feeding is all adopted in crystallizer upper end and zero section water inlet, cool off even, effective, billet quality stable, effectively improves casting speed, slab quality and the production economy efficient that has conticaster now.

Wherein: 8 zero sections sprays of water inlet 7 lower flanges, 81 spray heads, 82 showers, 9 foot-roller units of 64 0 sections water inlet pipe 641 showers of fixed head 62 water inlet pipes, 63 return pipes in the middle of 1 top flange, 3 upper flanges, 4 water jackets, 5 copper pipes, 6 shells 61.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail, can makes the professional and technical personnel more understand the utility model, following embodiment is made amendment, it all is possible adding and replacing, and does not all exceed protection domain of the present utility model.
Embodiment 1, such as Fig. 4,5, shown in 6, a kind of rectangular bloom, the improvement structure of bloom tube type mold zero section spray, by top flange 1, upper flange 3, water jacket 4, copper pipe 5, shell 6, lower flange 7, zero section spray 8, foot-roller unit 9 and seal, the attachment bolt nut forms, fixed head 61 in the middle of middle part, crystallizer outer ring is fixed with, crystallizer water inlet pipe 62, return pipe 63, zero section water inlet pipe 64 is separately fixed on the middle fixed head 61, zero section spray 8 is comprised of shower 82 and the spray head 81 that is fixed on the shower 82, zero section spray 8 is comprised of two sections showers 82 that are L-type, two sections showers 82 have respectively water inlet 641, and zero section water inlet pipe 64 joins with the water inlet 641 of two showers respectively.It is same as the prior art that all the other do not state part.The utility model is to improve on the basis of existing crystallizer, the shower 82 that the whole shower of ring-type is modified into two sections L-types forms, and as long as a side damages the one-sided shower of maintenance, and during maintenance as long as shift out from the side, convenient for maintaining has reduced maintenance cost.
