Description
Technical field
The present invention relates to technical field of refractory materials, more particularly to a kind of preparation method of magnesia synthetic material.
Background technology
The essential mineral calcium oxide of magnesia synthetic material, magnesium oxide are the high materials of fusing point, and chemical stability is high；White clouds
Stone ore or magnesite sintering early stage are mainly controlled by diabatic process, and when sample is sintered, heat has the heat transfer of an ecto-entad
Process, particle surface are heated, while discharging CO2Highly active crystallite is generated, heat Jing is delivered to inside for a period of time
During granule, there is sintering phenomenon as heated time is long in the high microcrystal grain living in surface, is formed and retains magnesite with some strength
The duricrust of ore deposit construction profile, i.e., so-called " female salt illusion ", a large amount of presence of " female salt illusion " in light-burned powder body can serious shadow
The uniformity of the light-burned powder body of sound and sample later stage densified sintering product, it is separate between illusion to be distributed in island shape.Inside sample
Also there are a large amount of gaps and irregular holes, be widely distributed in inside aggregate, between aggregate.Pore size integrally compares
Greatly, and it is interconnected to form super large pore.When in light-burned powder body, the generally existing of illusion can cause molding, densification is difficult, hinders
The sintering of sample.
Aquation problem in production, storage and transportation, always limits the calcareous fire proofed wood of magnesia especially magnesium
The bottleneck of material popularization and application, improves the centre point that sintering, synthesis technique are always magnesia synthetic material research.
The problems referred to above require to improve the consistency of magnesia synthetic material.It is for improving the consistency of magnesia synthetic material, main
That is, magnesia synthetic material is burnt till using superhigh temperature kiln by improving sintering temperature；Two step calcination methods, i.e., with soft burnt lime
Stone, magnesite or light dolomite are pressed into waste base, then 1600～1700 DEG C of Jing burns till, and also improves magnesia conjunction to a certain extent
Into the hydration resistance of material；The consistency for improving the magnesia synthetic material of synthesis by adding sintering aid is also currently extensively to adopt
Method.
The present invention combines addition sintering aid, active nano material technology and mechanical activation measure and is intended to explore new raw material
Handling process, prepares the good magnesia synthetic material of high-compactness, hydration resistance with this, is widely used in dry materials, ramming mass etc.
Field.
The content of the invention
The present invention provides a kind of preparation method of magnesia synthetic material, solve existing magnesia synthetic material consistency it is low,
The bad problem of hydration resistance.
For solving above-mentioned technical problem, the technical scheme is that：
A kind of preparation method of magnesia synthetic material, comprises the steps：
(1) by magnesia unslacked calcium powder abundant fine grinding, powder particle size reaches less than 20 microns, obtains light-burned calcium and magnesium powder and fine powder, separately
Outward, by iron oxide red abundant fine grinding, powder particle size reaches 30～50 microns；
(2) fine powder for obtaining step (1) carries out common mill, and the uniform addition activity during common mill with fine grinding iron oxide red
Nano-calcium carbonate, the addition of the active nano-calcium carbonate are the 1%～8% of fine powder and fine grinding iron oxide red weight；
(3) the common pulverized powder obtained to step (2) adds water, and stirs rolling in being put into chaser, it is to be mixed it is uniform, rolled
Hot temperature >=40 DEG C；
(4) wet-milling for obtaining step (3) adds ball press densification, pressure ball process to make ball base；
(5) the ball base for obtaining step (4), spontaneously dries；
(6) dry body that step (5) is obtained is put in kiln and is fired, firing temperature be 1600～1700 DEG C, insulation 2～
6 hours, obtain magnesia synthetic material.
Wherein it is preferred to, the CaO content ＞ 8% in the light-burned calcium and magnesium powder and fine powder that step (1) obtains.
Wherein it is preferred to, in step (3), the addition of water is the 15～20% of the pulverized powder weight altogether.
Wherein it is preferred to, after described step (5) natural drying, the moisture of ball base is less than 0.4%.
Beneficial effect of the present invention：
The method have the characteristics that nm-class active calcium carbonate additive dispersion is high, with great specific surface area, thus
With very high surface energy, lattice can be preferably activated, increase sintering driving force, in addition, nano active additive and calcium magnesite,
Iron oxide red contact interface is big, increases the quick diffusion area of particle, improves sintering activity and accelerates sintering process, reduces sintering temperature, carry
High densification rate, promotes microstructure uniformity；The female salt produced during the abundant fine grinding destruction of magnesia unslacked calcium powder is light-burned is false
As, meanwhile, the sintering activity of magnesia unslacked calcium powder is improved using mechanical activation；Abundant fine grinding iron oxide red Jing chaseies mixed grind and magnesia unslacked
Calcium powder mixes evenly, and effective contact area is bigger and activity is higher, is conducive to improving sintering character, it is possible to relatively
Magnesia synthesis material is obtained in low firing temperature, shorter firing time, has both been effectively reduced coal consumption, control production cost, and
Ensure the abundant sintering of magnesia synthesis material, improve magnesia synthesis material densified sintering product.
The magnesia synthesis material prepared with the inventive method, free CaO content 7～50%, bulk density >=3.3g/cm3 show
The porosity≤0.5%, hydration resistance are good.
