Specific embodiment
A kind of circular thin-wall base equipment, have big packet, tundish (band submersed nozzle), inside and outside crystallizer, clamping deflector roll and
Saw cutting device etc..Structure is shown in Fig. 1.
Submersed nozzle is two, and mouth of a river oblateness band list lateral openings can be such that molten steel rotates.Oblateness opening position is set
The jet angle for setting both direction, one is obliquely upward, for melting covering slag；It is another oliquely downward, for filling molten steel
And rotating molten steel in the same direction, the molten steel of rotation can float impurity therein, improve the pure of circular thin-wall slab
Degree.Structure is shown in that Fig. 2, double-head arrow indicate molten steel flow direction.
Outer crystallizer is ears shape.For common crystallizer, when submersed nozzle is inserted between inside and outside crystallizer
Cavity when, the mouth of a river with around inside and outside crystallizer gap and remaining wall thickness compared with it is much smaller.The outer crystallizer of ears shape exists
Ear shape structure is opened up at the mouth of a river, forms annular wall thickness with the mouth of a river, the wall thickness at the mouth of a river is suitable with remaining wall thickness, in this way when molten steel pours
When casting, it is not easy to the defects of generating slag inclusion at the mouth of a river.Structure is shown in Fig. 2.
Steam pumping channel is arranged in interior crystallizer, and otherwise, a large amount of steam that secondary cooling water generates can not be discharged, and influences the same of production
When, also increase security risk.Structure is shown in Fig. 1.
Shielding case is set.When the cooling circular thin-wall base inner wall of secondary cooling water, interior crystallizer steam channel is excluding steam
Meanwhile also secondary cooling water part being discharged.To prevent this phenomenon, shielding case is provided with below interior crystallizer, for being discharged
While steam, the loss of secondary cooling water is reduced.
The phenomenon that roll shape for supporting roller (guide) apron is designed using encapsulating type, and can clamp pipe again will not be such that its generation is pinched,
Improve the quality of circular thin-wall base.Structure is shown in Fig. 3.
Saw cutting device is vented, its main feature is that being provided with several gas vents on saw blade.Secondary cooling water generates a large amount of
A part is discharged from the steam channel of interior crystallization in steam, and rest part is then discharged by saw cutting device.
Interior crystallizer can be mobile relative to outer crystallizer.It can be according to throwing and the parameter tune of breakout prediction during production
Whole position, changing the taper for effectively contacting green shell prevents locking.Structure is shown in Fig. 1.
Interior crystallizer lengthens, and increases inside steel billet intensity of cooling, and in casting process, molten steel is at interior crystallizer
It is initially formed wall thickness, is conducive to the solidification of wick-containing, while reducing interior intensity of cooling.
