Abstract
The utility model provides a kind of tundish of resistance to melting loss, the permanent layer with integral cast, and permanent layer corner is equipped with the L-shaped prefabricated component in cross section, and the prefabricated component is installed at the external corner at permanent layer turning.The utility model improves tundish permanent layer, and tundish corner installs L shape prefabricated component in advance, considerably increases its resistance to melting loss degree.The incremental preform structure of width makes to be more firmly mounted from top to bottom for longitudinal section, also increases its service life.Turning prefabricated component can carry out integral replacing when the light maintenance of midway, and entire tundish permanent layer is enable to match, and improve the service life of tundish permanent layer.
Description
Technical field
The utility model belongs to steelmaking equipment technical field, and in particular to a kind of tundish of resistance to melting loss.
Background technique
Steel plays very important work as a kind of important basic raw material in the economic development of countries in the world
With.Tundish is the refractory material containers used in mini-mill steelmaking, receives to pour the molten steel to get off from ladle first, then
It is assigned in each crystallizer by middle water containing opening again.Tundish has in steelmaking process to be shunted, even pours, depressurizes, removing
The effects of impurity.
Tundish refractory lining mainly includes heat insulation layer, permanent layer and working lining.In tundish permanent layer is integrated poured
Between packet in, molten steel, which washes away, can make the castable at tundish containment wall corner position melting loss or cracking, corner's refractory material occur
Due to being washed away by molten steel etc., other position refractory materials of melting loss speed ratio tundish containment wall are bigger, thus current situation out
Portion damages and then influences the service life of entire tundish permanent layer.
Utility model content
To solve the above-mentioned problems, the utility model proposes a kind of tundish of resistance to melting loss, specific technical solution is as follows:
A kind of resistance to melting loss tundish, the permanent layer with integral cast, permanent layer corner are equipped with prefabricated component, institute
Prefabricated component is stated to be installed at the external corner at permanent layer turning.
Preferably, the prefabricated component cross section is L-shaped.
Preferably, width is incremented by from top to bottom for the prefabricated component longitudinal section.
Preferably, gravity flow casting material is perfused between the prefabricated component and permanent layer.
Preferably, it is described gravity flow casting material be poured between prefabricated component and permanent layer there are 40mm-70mm gap in.
The utility model has the beneficial effects that:
The utility model improves tundish permanent layer, and tundish corner installs L shape prefabricated component in advance,
Considerably increase its resistance to melting loss degree.The incremental preform structure of width makes to be more firmly mounted from top to bottom for longitudinal section, also increases
Its service life is added.Turning prefabricated component can carry out integral replacing when the light maintenance of midway, keep entire tundish permanent layer mating
It uses, improves the service life of tundish permanent layer.

Specific embodiment
With reference to the accompanying drawing and the embodiments of the present invention make into one a kind of tundish of resistance to melting loss of the utility model
Step detailed description.
A kind of resistance to melting loss tundish, the permanent layer 3 with integral cast, permanent layer corner are equipped with prefabricated component 2,
The prefabricated component is installed at the external corner at 3 turning of permanent layer.Specific installation method is as follows: before being poured tundish permanent layer,
First install integrated precast part in advance at the external corner at tundish turning, prefabricated component cross section is L-shaped, referring to Fig. 2, with sun
Angle matching.Permanent layer refractory material is poured at other positions of tundish containment wall again.
Width is incremented by from top to bottom for 2 longitudinal section of prefabricated component, referring to Fig. 3.Considerably increase its resistance to melting loss degree.It is vertical to cut
The incremental preform structure of width makes to be more firmly mounted from top to bottom in face, also increases its service life
In order to be tightly combined prefabricated component with permanent layer, gravity flow casting is perfused between the prefabricated component 2 and permanent layer 3
Material, gravity flow casting material be poured between prefabricated component and permanent layer there are 40mm-70mm gap in, by flow automatically casting material make
Prefabricated component is combined closely with permanent layer.
In use process, the molten steel to get off is poured in tundish receiving from ladle, and molten steel is through molten steel beam area 1 then again by centre
Water-coating port 4 is assigned in each crystallizer.During use, the corner for the most serious that suffers erosion due to installing in advance
Good L shape prefabricated component considerably increases its resistance to melting loss degree.It cannot continue to make when the material melting loss for corner location occur is serious
Used time can also remove the turning prefabricated component of damage with pneumatic pick, then reinstall one block of new turning prefabricated section, more extend
The service life of tundish.
It is all made according to the patent scope of the utility model the foregoing is merely the better embodiment of the utility model
Equivalent changes and modifications should all belong to the covering scope of the utility model.
