Abstract
The utility model discloses a bridge of nose prefab of tower stove. It is including installing the prefab body in the stove outer covering, and the prefab body is including being used for installing the installation face and the reinforced working face with the stove outer covering installation, and the installation face sets up to the linear type structure, and reinforced working face is including last inclined plane, middle part vertical plane and lower inclined plane, thereby the angle on going up the inclined plane is greater than the angle on lower inclined plane and forms under the narrow wide cross-sectional shape structure. After adopting foretell structure, can slow down the impact that the aluminium ingot produced when dropping to it, reduce wearing and tearing and the emergence of the problem that drops, the structural design on lower part inclined plane is favorable to detaining solid materials such as aluminium ingot, has prolonged life greatly, in addition, the prefab body adopts high strength steel fibre and special properties refractory material to make, has excellent high temperature mechanical strength, excellent mechanical shock resistance can, it is stand wear and tear, thermal shock resistance is good, in addition, its reasonable structural design makes simple to operate, it is convenient to be under construction.
Description
Technical Field
The utility model relates to an accessory of tower furnace, in particular to a nose bridge prefabricated part of tower furnace.
Background
The tower furnace widely used in the aluminum processing industry mainly comprises: tower, melting chamber and holding chamber. When the device is used, solid materials such as aluminum ingots, returned materials and the like are added from the upper opening of the tower part, the nose bridge is positioned at the lower part of the tower part and forms a narrow passage with other 3 feeding impact areas, and the added solid materials such as the aluminum ingots, the returned materials and the like are retained in the narrow passage so as to be preheated by using flue gas and furnace gas, so that the heat efficiency is improved, and the burning loss is reduced.
Traditional bridge of the nose is because structural design is unreasonable, and high temperature mechanical strength is poor, uses a period of time after, and wearing and tearing are serious, drops even for bridge of the nose and the passageway that other 3 face feeding impact regions formed enlarge, so that the solid material of joining can not be detained here, directly gets into melting chamber, can not utilize flue gas, burner gas to preheat it, in addition, the nozzle directly melts towards the solid material, has increased the scaling loss, consequently, the intensity of bridge of the nose part and reliability are vital to tower furnace's performance.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a bridge of nose prefab that can increase of service life improves anti mechanical shock performance.
In order to solve the technical problem, the utility model discloses a bridge of nose prefab, including installing the prefab body in the stove outer covering, the prefab body is including being used for the installation face and the reinforced working face of installing with the stove outer covering, and the installation face sets up to the linear type structure, and reinforced working face is including last inclined plane, middle part vertical plane and lower inclined plane, thereby the angle on going up the inclined plane is greater than the angle on lower inclined plane and forms under the narrow wide cross-sectional shape structure.
And the mounting surface of the prefabricated part body is connected with the furnace shell by adopting a screw.
One end of the screw is in threaded connection with the mounting surface of the prefabricated part body, and the other end of the screw is welded and fixed with the furnace shell.
And a gap between the mounting surface of the prefabricated part body and the furnace shell is filled with a casting material.
The prefabricated part body is made of high-strength steel fibers and special-performance refractory materials.
The length of the upper inclined surface is longer than that of the lower inclined surface by more than 2 times.
After adopting foretell structure, because the installation face of prefab body sets up to the linear type structure, reinforced working face is including last inclined plane, middle part vertical plane and down inclined plane and go up the inclined plane the angle be greater than the angle of inclined plane down thereby form narrow-end-width's cross-sectional shape structure down, thereby can slow down the impact that produces it when the aluminium ingot drops, the emergence of wearing and tearing and drop problem has been reduced, the structural design on lower part inclined plane is favorable to detaining solid materials such as aluminium ingot, service life has been prolonged greatly, in addition, the prefab body adopts high strength steel fibre and special properties refractory material to make, excellent high temperature mechanical strength has, excellent anti mechanical shock property, it is wear-resisting, thermal shock resistance is good, in addition, its reasonable structural design makes simple to operate, it is convenient to construct.
Drawings
Fig. 1 is a structural schematic diagram of the installation state of the nose bridge prefabricated member of the present invention.
Detailed Description
The nose bridge prefabricated member of the present invention will be described in further detail with reference to the accompanying drawings and the following detailed description.
As shown in the figure, the utility model discloses a bridge of nose prefab, including installing prefab body 2 in stove outer covering 1, the bridge of nose is located the tower portion lower part of stove outer covering 1, prefab body 2 is including being used for installing 3 and reinforced acting surface 4 with the stove outer covering installation, installation face 3 sets up to the linear type structure, adopt screw rod 8 to connect between prefab body 2's the installation face and the stove outer covering 1, reinforced acting surface 4 is including last inclined plane 5, middle part upright surface 6 and down inclined plane 7, thereby the angle that goes up inclined plane 5 is greater than the angle of inclined plane 7 down and forms the narrow wide cross sectional shape structure down, as can be seen from the figure, the alpha angle of the upper inclined plane is greater than the beta angle of.
Further, the one end of screw rod 8 and the installation face of prefab body of saying carry out threaded connection, the other end and the stove outer covering 1 welded fastening of screw rod 8 for simple to operate, it is convenient to be under construction, the clearance between the installation face of prefab body 2 of saying and the stove outer covering 1 adopts the pouring material to fill, prefab body 2 of saying adopts high strength steel fibre and special properties refractory material to make, makes its high temperature strength high, anti mechanical shock ability reinforce, in addition, the length of the upper slope face 5 is good at more than 2 times of lower inclined face 7 length.
