Abstract
The invention discloses an extended nozzle brick which comprises a nozzle, a base brick body and a lengthened brick body, wherein the nozzle and the base brick body are made of alumina-carbon material; the lengthened brick body is made of zirconia-carbon material; and an argon blowing port is formed in the outer side of the nozzle. Compared with the prior art, the extended nozzle brick has the characteristics of high fireproofness, high high-temperature strength, low linear change rate, volume stability, good corrosion resistance, etc.; the effect of preventing molten steel from spattering and the effect of preventing a turbulent flow during continuous casting protection can be achieved; and the extended nozzle brick can achieve a long service life.
Description
Technical field
The invention belongs to fire resisting material field, be specifically related to a kind of extended nozzle.
Background technology
Along with continuing to increase of continuous casting ratio, process for making the most perfect, protective casting seems more and more important, long nozzle molten steel can be protected to wrap in flowing to from ladle during not by molten steel oxidation, in use protection molten steel not with air contact.
There are problems in currently used long nozzle, molten steel is opened before watering and opened after watering the various problems such as splash and turbulent flow occurs.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of extended nozzle.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically performed by: a kind of extended nozzle, is aluminum carbon material including the mouth of a river, basis brick body and lengthening brick body, the mouth of a river and basis brick body, lengthening brick body is zirconium carbon material, and the outside at the described mouth of a river is provided with argon blowing hole.
Wherein, it is coated with iron-clad outside the described mouth of a river and basis brick body.
Wherein, the cross section of described whole extended nozzle is annular.
Beneficial effect: the present invention is compared with conventional art; there is the features such as refractoriness is high, elevated temperature strength is high, Linear change rate is low, volume stability, corrosion-resistant property are good; can meet continuous casting protective casting prevents molten steel splash and the effect of turbulent flow, and can reach long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
A kind of extended nozzle as shown in Figure 1, including the mouth of a river 1, basis brick body 2 and lengthening brick body 3, the mouth of a river 1 and basis brick body 2 are aluminum carbon material, lengthening brick body 3 is zirconium carbon material, the outside at the described mouth of a river 1 is provided with argon blowing hole 4, being coated with iron-clad 5 outside the described mouth of a river 1 and basis brick body 2, the cross section of whole extended nozzle is annular.
Claims (3)
1. an extended nozzle, it is characterized in that, be aluminum carbon material including the mouth of a river (1), basis brick body (2) and lengthening brick body (3), the mouth of a river (1) and basis brick body (2), lengthening brick body (3) is zirconium carbon material, and the outside of the described mouth of a river (1) is provided with argon blowing hole (4).
