Abstract
The invention discloses a kind of stalk of duplex, including stalk body, stalk body inner side is provided with layer protective layer.The present invention is compared with conventional art; by stalk inner side addition layer protective layer; facilitate maintenance and the replacement cost in stalk later stage; protective layer inside stalk only needs to change the silicon carbide ceramics of relative moderate when scrapping; and preserve the silicon nitride ceramics outside; convenient maintenance, has saved cost, improves benefit.
Description
Technical field
The invention belongs to performance function ceramics manufacture field, and in particular to a kind of stalk of duplex.
Background technology
Silicon nitride ceramics thermal coefficient of expansion is low, thermal conductivity is high, therefore its resistance to sudden heating is splendid, and super than steel and engineering resistance to
Thermalloy steel is light, therefore is increasingly favored in fire resisting material field.Silicon nitride stalk general action steel mill is carried
The effect of molten steel is taken, because its inner side touches molten steel first, heat-shock is big, therefore its inner side is to be easiest to aging or scrap
's.
The content of the invention
Goal of the invention：The purpose of the present invention is to solve the shortcomings of the prior art, there is provided a kind of stalk of duplex.
Technical scheme：In order to reach foregoing invention purpose, what the present invention was specifically performed by：A kind of duplex
Stalk, including stalk body, stalk body inner side are provided with layer protective layer.
Wherein, the stalk body is silicon nitride material, and protective layer is silicon carbide material.
Wherein, the stalk body and protective layer are by heat-resisting glue bonding.
Wherein, the thickness of the protective layer is 0.5 ~ 2cm, can effectively slow down the thermal shock power of molten steel.
Beneficial effect：The present invention, by stalk inner side addition layer protective layer, facilitates stalk compared with conventional art
The maintenance in later stage and replacement cost, the protective layer inside stalk only need to change the silicon carbide ceramics of relative moderate when scrapping,
And the silicon nitride ceramics outside is preserved, cost has been saved in convenient maintenance, improves benefit.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
A kind of stalk of duplex as shown in Figure 1, including stalk body 1, stalk body（1）Inner side is provided with
Layer protective layer 2, the stalk body 1 be silicon nitride material, protective layer 2 be silicon carbide material, the stalk body 1 with
Protective layer 2 is bonded by heat-resisting glue 3, the protective layer, and 2 thickness is 0.5 ~ 2cm.
Claims (4)
