Description

A kind of cement rotary kiln stove castable refractory
Technical field
The present invention relates to technical field of refractory materials, more particularly to a kind of cement rotary kiln stove castable refractory and its system Preparation Method.
Background technology
In blast furnace, pipeline of hot air furnace etc., in order to ensure temperature of the high-temperature gas in course of conveying, to be built by laying bricks or stones in pipeline Refractory material.In high temperature kiln in use, being the heat insulation effect of guarantee kiln, while improving inner lining of kiln service life, Chang Cai Built by laying bricks or stones with being combined by heavy brick and lightweight refracrory, cause inner lining of kiln thermal capacity big, thermal efficiency reduction.Due to traditional lightweight Energy-saving material has the porosity big, and water absorption rate is high, and intensity is relatively low, the defect of heat preservation and energy conservation effects difference, it is impossible to be directly used in Working lining, it is necessary to built by laying bricks or stones with multiple layer refractory, also causes caliber increase, and this causes weight of equipment and volume increase, and material disappears Consumption and cost increase.
The content of the invention
In view of the above-mentioned problems, the present invention is provided, a kind of light weight, intensity are high, thermal conductivity factor is low, good integrity cement is returned Rotary kiln stove castable refractory and preparation method thereof.
To reach above-mentioned purpose, the concrete technical scheme that the present invention is used is as follows:
A kind of cement rotary kiln stove castable refractory, including following components raw material and parts by weight:Including following components raw material and Parts by weight:50-55 parts of 1-8mm lightweight anorthites, 5-10 parts of perlite rawore, 10-25 parts of 1-0mm lightweight Bo Naite, 200 mesh 5-10 parts of lightweight pyrophyllite in powder, 325 5-10 parts of mesh light-weight mullite fine powders, 5-10 parts of silicon powder, the Al that 2 ~ 3 μm of particle diameter2O3 It is micro- 5-10 parts of powder, 3-8 parts of aluminate cement, 5-10 parts of 0.25-1.5mm glass beads, 0.31 part of calgon, explosion-proof fiber 0.3 part.
It is preferred that, the lightweight anorthite is matched somebody with somebody by particle diameter 1-3mm and 3-8mm two kinds of particles level to be formed, particle diameter 3-8mm's Particle accounts for the 40% of lightweight anorthite gross weight.
It is preferred that, the granularity of the perlite rawore is 0-1mm.
It is preferred that, the proportion of the liquor alumini chloridi is per cubic centimeter for 1.25 grams.
It is preferred that, the explosion-proof fiber is 3 μm of diameter, length 8mm polypropylene fibre.
A kind of preparation method of cement rotary kiln stove castable refractory, comprises the following steps:By the various originals in scheme Material adds and mixing is stirred in mixer, and the liquor alumini chloridi that addition accounts for its weight 10-12% stirs, the material note being stirred Enter mould, vibrating forming carries out fire, temperature is incubated 4h when reaching 100 DEG C, temperature is incubated 8h when reaching 450 DEG C after maintenance 24, It can come into operation.
Beneficial effects of the present invention are as follows:The present invention is used as base using lightweight anorthite, lightweight Bo Naite, glass bead Body, material thermal conductivity is small, and chemical property is stable, has good repellence, good heat-insulation effect, resistant to corrosion to acid, alkali.
The present invention uses lightweight pyrophyllite in powder, light-weight mullite fine powder, silicon powder, the Al that 2 ~ 3 μm of particle diameter2O3 Micro mist, makees For the gap between fine powder filler aggregate, aggregate surface is uneven, increases the specific surface area of the contact between fine powder so that both With reference to closer;Using liquor alumini chloridi, alumina cement, perlite rawore, silicon powder and Al2O3 Micro mist is used as matrix conjugate Fine powder and aggregate, are bonded together under high temperature, while can give birth at high temperature by matter by the effect of liquor alumini chloridi chemical bond Into reaction product aluminum phosphate, the material such as calcium phosphate is firmly combined together aggregate and fine powder, promotes to blend more, so that Improve the overall bond strength of castable;Perlite rawore therein is a kind of light material, can be expanded with temperature rise volume, can The defect of shrinkage front change greatly is raised with temperature to change light material, light material contraction distortion will not be caused, under its high temperature Expansion just can progressively offset the contraction of material, improve the stability of material.It has excellent property than expanded perlite Can, one is that cost reduction need not be calcined, but expanded perlite is after calcining, will not continue to expansion, with temperature rise only meeting Light material is caused to shrink.
The present invention is by adding the gas permeability in explosion-proof fiber raising light material under low temperature, and explosion-proof fiber is in fire process Softening, contraction, fusing, eventually form stomata and are carbonized, and in material internal formation network stomata, open passage, can not only mitigate Material internal stress, while the internal micropore produced can reduce thermal conductivity again, improves energy-saving effect.Therefore, whole technology is passed through Scheme can just realize that material internal is firmly combined with, while low heat conduction can be realized, volume, which does not shrink not expanding, keeps volume steady Fixed performance.
