Abstract
The utility model discloses a nozzle brick, which relates to refractory equipment and comprises a brick body and an upper nozzle matched with the brick body. The nozzle brick is characterized in that the external shape of the brick body is cylindrical, the outside of the brick body is wrapped by a metal shell, a central hole is arranged inside the brick body, a flared nozzle is arranged above the central hole, the bore diameter of a hole arranged on a base plane of the flared nozzle is larger than that of the central hole of the nozzle brick, and central lines of the two holes form a straight line. The nozzle brick has the advantages of fine fire resistance, high thermal shock stability, scour resistance, corrosion resistance and the like, the service life of the nozzle brick is longer, and the nozzle brick can be used as a refractory material for a continuous casting tundish for casting steel.
Description
Technical field
The utility model relates to a kind of refractory equipment, particularly relates to the nozzle brick that a kind of steel-making continuous casting tundish is used.
Background technology
Bag water nozzle brick in the prior art in the middle of the continuous casting comprises the brick body built in the centre, the endoporus in the brick body, the mouth of a river of matching with brick body endoporus, and the brick shape is square, and its endoporus is a circle, and the shape at the mouth of a river is and the corresponding circle of endoporus.The internal diameter size at its mouth of a river of nozzle brick of this shape is identical, is not suitable for the circulation of molten steel, and when casting, molten steel washes away nozzle brick continuously, makes the mouth of a river very easily hole enlargement or corrosion.In order to guarantee safety in production, must often change nozzle brick, increased the cost of enterprise.Simultaneously brick is external does not have a metal-back yet, and fire-resistant effect is relatively poor, and thermal shock resistance is lower.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of fire resistance good, and thermal shock resistance is higher, but the erosion-resisting nozzle brick of antiscour.
The technical scheme that the utility model adopted is:
A kind of nozzle brick; Comprise the filling pipe end that brick body and brick body match, it is characterized in that: said brick external is shaped as cylindrical, and the brick external is enclosed with metal-back; Brick body inside is provided with centre bore; The top of centre bore is provided with a tubaeform mouth of a river, and the aperture of tubaeform mouth of a river baseplane perforate is greater than the aperture of nozzle brick centre bore, and the center line in two holes is in alignment.
The beneficial effect of the utility model is: the mouth of a river of the utility model nozzle brick is designed to horn-like, and mouth of a river internal diameter enlarges naturally, has kept consistent with the flow of molten steel, has good antiscour, corrosion resistance, and service life is longer.The utility model is enclosed with metal-back in the brick external simultaneously, and its fire resistance and thermal shock resistance are also better.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description.
As shown in Figure 1, nozzle brick comprises the filling pipe end 2 that brick body 1 and brick body 1 match; Said brick body 1 outer shape is cylindrical, and brick body 1 external packets is wrapped with metal-back 3, and brick body 1 inside is provided with centre bore 4; The top of centre bore 4 is provided with the mouth of a river 2; The mouth of a river 2 internal diameter from bottom to up slowly increases to horn-likely, and the aperture of the tubaeform mouth of a river 1 baseplane perforate 5 is greater than the aperture of nozzle brick centre bore 4, and the center line 6 in two holes is in alignment.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
