Abstract
The invention relates to a duplex type crystallizer which comprises a sliding type crystallizer which is taken as an upper crystallizer and a synchronous circulation mobile cooling belt device which is taken as a lower crystallizer. The duplex type crystallizer consists of the upper crystallizer and the lower crystallizer. The lower crystallizer consists of more than two cooling belts, a driven roller, a cooling device, a supporting roller and a driving roller, wherein, the driven roller and the driving roller are respectively positioned at the two ends of the cooling belt, the supporting roller and the cooling device are arranged between the driven roller and the driving roller, each cooling belt surrounds at the periphery of the driven roller, the cooling device, the supporting roller and the driving roller. The invention adopts the fractional crystallizer structure, the upper crystallizer only plays the role of shell-making, which can decrease the length and reduce the motion resistance of the casting blank; and no motion resistance exists between the lower crystallizer and the casting blank, thus lengthening the lower crystallizer and meeting the requirement of cooling the casting blank. The adoption of the duplex type crystallizer can promote the casting speed, improve the cooling capability, increase the productivity of a continuous casting machine and lower the occurrence possibility of accidents.
Description
Technical field
The present invention relates to the metal casting technology of metallurgical industry, the composite crystallizer in particularly a kind of continuous casting installation for casting.
Background technology
At present, along with improving constantly that the continuous casting production capacity requires, the requirement of conticaster casting speed is also improved constantly, the casting blank shell thickness that goes out the crystallizer end opening is more and more thinner, after strand goes out crystallizer, be easy to deform, more seriously because of cooling off deficiency, under existing technical conditions, teeming speed improves, and the length of crystallizer also needs to increase, thereby has caused the increase of strand process frictional resistance, make serious accidents such as bleed-out take place again and again, caused great economic loss.
In the prior art, the method of sufficient roller, copper coin or cooling grid is installed in employing at the crystallizer end opening, though to a certain degree alleviating subproblem, but exist still that cooling effect is not good enough, resistance of billet withdrawal is big, many weak points such as cleaning difficulty take place after the bleed-out accident, fundamentally thoroughly do not deal with problems.
Summary of the invention
In order to solve existing crystallizer under high teeming speed situation, the problem that the strand resistance is big and cooling is not enough, task of the present invention provides a kind of composite crystallizer, and it can thoroughly solve existing contradiction, reduces the possibility of major accidents such as casting blank deformation, bleed-out take place widely.
Technical solution of the present invention is as follows:
A kind of composite crystallizer, it comprises the slidingtype crystallizer, it also comprises two above synchronous circulation mobile salband devices; Described slidingtype crystallizer is last crystallizer, and described synchronous circulation mobile salband device is following crystallizer, and this composite crystallizer is made up of last crystallizer and two parts of following crystallizer; Described crystallizer down is made up of two above salbands, driven voller, cooling device, backing roll and driven rollers, driven voller and driven roller lay respectively at two ends of salband, backing roll and cooling device are placed between driven voller and the driven roller, and each salband is surrounded on the periphery of driven voller, cooling device, backing roll and driven roller.
The present invention adopts fractional crystallizaton device structure, and last crystallizer is the slidingtype crystallizer, only works the shell effect of making, and therefore can reduce length, reduces the strand resistance of motion widely; Following crystallizer mainly by forming with the synchronization-moving salband of strand, has not had the resistance of motion between following crystallizer and the strand, can make down the crystallizer lengthening, satisfies the needs of cooling strand.So just can under the situation that improves teeming speed, reduce the resistance of motion of strand in whole crystallizer, improve cooling capacity, thereby finally improve the production capacity of conticaster, the generation of reduction accident.
Description of drawings
Fig. 1 is the structural representation of a kind of composite crystallizer of the present invention.
Fig. 2 is the last crystallizer plan structure schematic diagram of Fig. 1 composite crystallizer.
Fig. 3 is the following crystallizer plan structure schematic diagram of Fig. 1 composite crystallizer.
Number in the figure: 1 is last crystallizer, and 2 are following crystallizer, and 3 is driven voller, and 4 is cooling device, and 5 is backing roll, and 6 are following crystallizer salband, and 7 is driven roller.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the present invention is a kind of composite crystallizer, and it is made up of last crystallizer 1 and 2 two parts of following crystallizer.Last crystallizer 1 is the slidingtype crystallizer that tradition is used, and following crystallizer 2 is a kind of synchronous circulation mobile salband devices.Following crystallizer 2 can be provided with more than two, two synchronous circulation mobile salband devices can be arranged to relatively and a group of putting.
Following crystallizer 2 is made up of two above salbands 6, driven voller 3, cooling device 4, backing roll 5 and driven rollers 7, driven voller 3 and driven roller 7 lay respectively at two ends of salband 6, backing roll 5 and cooling device 4 are placed between driven voller 3 and the driven roller 7, and each salband 6 is surrounded on the periphery of driven voller 3, cooling device 4, backing roll 5 and driven roller 7.Following crystallizer 2 in the present embodiment is provided with four synchronous circulation mobile salband devices, constitutes billet caster.
In this composite crystallizer, last crystallizer only works the shell effect of making, and following crystallizer has played and supported and the further effect of cooling strand.In casting cycle, the basket pouring of molten steel process is in composite crystallizer, molten steel is tentatively cooled off through last crystallizer, form certain thickness base shell, enter down crystallizer, driven roller drives salband and the same moved further of strand, continues the cooling strand simultaneously, is sent crystallizer behind the final strand cooling forming.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention conversion, the modification of the foregoing description.
