Abstract
By the present invention in that filling the surface pore of zircon base fire resistive material product with ceramic phase, surface trepanning gap and aperture are significantly reduced, to provide zircon base refractory material having improved properties.
Description
Technical field
The present invention relates to usually have the zircon base refractory product for improving surface nature.
Background technology
Zircon temperature in use is high, chemical stability is good, corrosion resistance is strong, is a kind of fabulous special refractories.Such as
Using zircon as the compact zircon brick of raw material：It is mainly used for all kinds of glass furnaces and the shirt portion with glass metal contact site.It has
There is the excellent performance that intensity is high, corrosion resistance is strong.Product mostly uses selected raw material, fine grinding, isostatic pressed compression moulding（Or mud
Castable）, again through high-temperature firing at the production technology of product.Using zircon as the standard zircon brick of raw material：It is mainly used for
On the ladle and tundish of the positions such as the kiln bottom, the kiln wall that are not contacted with glass metal in glass furnace and steel mill.
The main component of zircon product is ZrO2•SiO2, zircon is heated at 1680 DEG C to be largely decomposed into ZrO2With
SiO2, zircon product to a variety of molten metals, acid reagent and liquid glass all have good corrosion resistance, but with alkalinity
Clinker is contacted with basic refractory, is easy to happen etching reaction.
Simultaneously as melt liquid such as metal, glass metal and refractory product are in direct contact, refractory material has the table of trepanning
Face also tends to adsorbing contaminant or clast or surface tends to receive simultaneously aggregated particle, this can lead to serious problems.
In order to overcome the problems referred above, it attempts in the prior art using the group coating or erosion resistant coating that refractory material is formed in situ.
But this coating or erosion resistant coating are more crisp and frangible, are unsuitable for thermal cycle.In addition, because other layer thermal expansion (or
Usual hot property) it is different from the thermal expansion (or usual hot property) of internal layer, stress is generated on the interface of coating and interior interlayer, from
And surface quality is negatively affected, and it is uneven to conduct heat.
Therefore, it is badly in need of a kind of zircon base refractory material having improved properties, while overcoming disadvantages mentioned above, keeps
Excellent properties known to zircon base refractory material.
Summary of the invention
The purpose of the present invention proposes improved zircon base refractory material, overcomes disadvantages mentioned above, while keeping zircon base
Excellent properties known to refractory material.
According to the present invention, there is the ceramic phase of sintering in zircon base refractory material stromal surface at least partly hole.
According to the present invention, the surface of aircon refractory only needs simply to impregnate and filling out for ceramic phase can be realized in sintering
It fills.
The surface pore of zircon base refractory material preferably with selected from aluminium, silicon, the oxide of zirconium and magnesium, a combination thereof, aluminium and
Nitride of silicon and combinations thereof is filled.
Solution or suspension are can be selected from suitable for dipping, zircon surface can use the metal compound for providing required metallic atom
Object solution is impregnated.Suitable metallo-organic compound includes ethyl orthosilicate, methyl orthosilicate, silane, acetic acid zirconium or packet
The chelate etc. of required metallic atom is included, suitable metal inorganic compound includes nitrate, chloride, oxychloride etc..
Alternatively, being introduced with suspension form, i.e., the material granule of suitable grain size such as average grain diameter is suspended in less than 100nm
In suitable liquid-carrier such as water or alcohol.Suitable material is, for example, silicon, aluminium, the metallic particles of magnesium or their oxide or nitrogen
The particle etc. of compound.
According to the present invention, then product surface, which be heat-treated, is sintered to form ceramic phase and and surface in gap
Strong combination is formed between matrix.
According to the present invention, can be processed after sintering with or without mechanical surface again need to be carried out to product.
Surface pore is filled due to the use of ceramic phase so that the open porosity of refractory surface significantly reduces, to
Reduce zircon base refractory material and caustic slag or between basic refractory since hole is in direct contact caused etch,
Adsorption and surface aggregation of the refractory surface for impurity in molten liquid etc. are also reduced simultaneously.Simultaneously by further burning
Knot ensures combination strong between matrix and filler, in this way, can generate smaller stress, reduces and peels off or crack.Simultaneously
According to the present invention, refractory surface roughness is significantly reduced.
Specific implementation mode
In order to which the present invention is better described, illustrated now by not limiting the embodiment of the scope of the invention.
1-solution of embodiment impregnates the surface of zircon refractory product.
By preparing 50 weight % aluminum acetates (chemical purity) solution.Under elevated pressure as under 2 atmospheric pressure, impregnated in the solution
Zircon refractory product 4 hours.Then 24 hours are dried to form gel in the trepanning of surface.At 900 DEG C, sintering 2 is small later
When, to form aluminium oxide ceramics phase filler in the trepanning of surface.By impregnation surface so that the open pore of refractory surface
Gap rate reduces up to 40%.
2-solution of embodiment impregnates the surface of zircon refractory product.
By mixing 50 weight % tetraethyl orthosilicates (chemical purity), 50 weight % isopropanols (chemical purity) form dipping
Solution.Under elevated pressure as under 2 atmospheric pressure, zircon refractory product is impregnated in the solution 2 hours.Then 24 hours are dried in table
Gel is formed in the trepanning of face.Repetitive operation is carried out after first time dipping and drying carries out second of dipping and drying, Zhi Hou
1000 DEG C are sintered 2 hours, to form silicon oxide ceramics phase filler in the trepanning of surface.It is reduced in surface opening porosity same
When, the aperture on surface is also substantially reduced from untreated product mean surface pore size.
3-suspension of embodiment impregnates the surface of zircon refractory product
Embodiment 2 is repeated, in addition to suspension oxidation zirconium nano particle forms suspension in water, mean particle size is less than
50nm.Zircon refractory product is impregnated in suspension 3 hours.Then 24 hours are dried to form gel in the trepanning of surface.
First time impregnate and it is dry it is laggard be sintered 2 hours at 1000 DEG C, with the formation zirconia ceramics phase filler in the trepanning of surface.
It is reduced simultaneously in surface opening porosity, the aperture on surface is also substantially reduced from untreated product mean surface pore size.
Above-mentioned specific embodiment is intended to illustrate the preferred embodiment of invention, to understand the essence of the present invention, and simultaneously
Claimed range, which limits, is not claimed to the present invention, obvious changes and modifications can be carried out on this basis.
Protection scope of the present invention is defined by the claims.
