Abstract
The present invention relates to a kind of high thermal shock long-life saggar and preparation methods.Andalusite particle, magnesium aluminate gel, calcia-stabilised zirconia micro mist, andalusite activity micro mist, alumina powder aggregate, Suzhou soil, additional bonding agent 0.1% ~ 0.15%, by raw material according to different weight percent, the product of the present invention is prepared for through material mixing, molding, drying, final high temperature calcining, this contains zirconium andalusite toughening saggar product and overcomes that existing there are the defects such as service life is not long, stability is poor, flexural strength is low.Saggar prepared by the present invention has many advantages, such as that high high temperature break resistant intensity, good thermal shock and service life are long.
Description
Technical field
It is main to propose a kind of toughening saggar of andalusite containing zirconium and preparation side the invention belongs to technical field of fire-resistant material preparation
Method.
Background technology
Saggar is that one kind holds burning device, is industrially frequently utilized that saggar to produce the ceramic or height that need high-temperature calcination
Warm electron pipe etc..Tunnel kiln is generally adopted by, is a kind of continous way heat-agglomerating equipment, according to the technique of sintered products
It is required that arranging required warm area and power, the product that needs are sintered directly or indirectly is placed in saggar, by propulsion system according to
The technological requirement product of product is moved with kiln car, in order to complete product sintering in burner hearth.During this, saggar warp
The impact of the normal high temperature for being subject to 1300 DEG C -1600 DEG C or so, various redox conditions and temperature instantaneous variation, simultaneously also
The change dramatically of temperature after kiln car kiln discharge is resistant to, thus it is extremely stringent to the performance requirement of saggar.
At present, the saggars such as the corundum of domestic production, silicon carbide, cordierite are difficult to meet for temperature, anti-folding
The requirement of intensity, service life and high chemical stability etc..Corundum saggar was produced on high temperature kiln using only 20 days
Raw crackle or rupture.Silicon carbide have the characteristics that it is oxidizable, oxidation rear surface preferably generate SiO2Glass phase, it is preferably dirty to product
Dye.Cordierite Basic Sagger is since the generation temperature of cordierite is closer to decomposition temperature, in relatively low temperature, cordierite content
Less, glass mutually a large amount of generations can be caused again by improving firing temperature, directly influence the creep resistance of product, therefore cordierite casket
Alms bowl is only applicable to moderate oven(Temperature≤1200 DEG C), it is impossible to meet high temperature.What is generally used at present is all corundum-mullite casket
Alms bowl, but due to the select permeability of raw material, cause the service life of product relatively low and stability is poor, craze and transfiguration, the anti-folding of high temperature
Insufficient strength, while there is phenomenon of rupture.
The content of the invention
The purpose of the present invention is overcoming above-mentioned saggar service life short, preferably deformed under high temperature, thermal shock resistance is poor, loading softening
The defects such as temperature is low provide a kind of production cost low and high temperature High anti bending strength, one kind andalusite containing zirconium toughening of service life length
Saggar and preparation method.
Purpose to realize the present invention, used technical solution are:A kind of toughening saggar of andalusite containing zirconium, it mainly by
It is prepared by the raw material of following weight percent:Andalusite particle 20%-30%, magnesium aluminate gel 20-30%, yttrium stable zirconium oxide are micro-
Powder 5-10%, andalusite activity micro mist 10% ~ 20%, alumina powder aggregate 15%-20%, Suzhou soil 3% ~ 5%, additional knot
Mixture 0.1% ~ 0.15%.
Preferably, additional bonding agent is the whole in paraffin, carboxymethyl cellulose, yellow starch gum.
Preferably, andalusite particle Al2O3Weight percentage is 60% or so, and iron content weight percentage is <
0.4% or so;Magnesium aluminate Al2O3Weight percentage is 60% or so, and iron content weight percentage is < 0.4% or so.
Preferably, the grain size of andalusite activity micro mist is 2 microns, alumina content >=60%, iron content < 0.4%.
Preferably, the grain size of zirconia powder is between 5000-8000 mesh.
Preferably, it is 0.045mm's that Suzhou soil, which selects grain size,.
Preferably, alumina powder aggregate is the spherical agglomerates that alumina powder shapes at normal temperatures, and when compacting can
To keep the integrality of ball.
A kind of preparation method of the toughening of andalusite containing zirconium saggar, comprises the technical steps that:(1) by raw material components according to not
Stirring 30min in vertical stainless steel mixer is put into weight percent to be uniformly mixed.(2)Prepare the saggar mold to be done;
(3) step will be passed through(1)Material with 630 tons of press cold moudlings, spontaneously dry;(4) step will be passed through(3)Dry material
With the high temperature kiln of 20m long through 1450 DEG C ~ 1480 DEG C of temperature calcination, when clinkering zone heat preservation 4-6 is small, ceramic saggar is obtained.
The present invention beneficial features be:(1)The present invention uses andalusite, zirconium oxide as primary raw material, in high temperature sintering mistake
Cheng Zhong, andalusite start to change into acicular mullite, can step-reaction in use, can be to avoid under long-time service
Saggar contraction distortion keeps volume stability, extends material lifetime;Magnesium aluminate gel active is big, and dispersiveness is high, also can be with andalusite
The flexible glass phase reaction of precipitation generates the good forsterite of performance, improves performance.(2)The present invention selects andalusite activity micro-
Powder, purity is high, and impurity content is few, and activity is big, can substitute common micro mist and use, and because fine size, can mix very
Uniformly, be conducive to improve substrate performance, after addition, hot high temperature break resistant intensity improves 6 times or more compared with traditional product.(3)This
The alumina powder aggregate of invention is convenient for packing space when having compacting, spherical agglomerated to know from experience contraction when being sintered under high temperature, so
Aggregate can form a circumferential weld with periphery substance afterwards so that product has toughness at high temperature, offsets the function of thermal stress, adds
The zirconium oxide product entered can not only improve the thermal shock resistance of saggar, moreover it is possible to greatly improve product corrosion resistance.Additional combination
Agent room temperature has combination, after discharging at high temperature, retains three kinds of different stomatas, is conducive to improve the thermal shock resistance of kiln furnitures
And toughness.The ceramic box alms bowl volume stability of method manufacture using the present invention, good thermal shock(1100 DEG C of water cooling > 100 times)Than
Similar product service life improves 4 times or more.
