Description
Technical field
The invention belongs to technical field of refractory materials, be specifically related to a kind of fire-resistant zircon corundum brick and preparation method thereof.
Background technology
Zircon corundum brick be with pure aluminum oxide powder and the zircon sand containing zirconium white 65%, silicon-dioxide about 34% melt in electric smelter cool in rear injection model and formed white solid, its lithofacies structure is made up of the eutectoid of corundum and the oblique stone of zirconium and glassy phase, be the eutectoid of the oblique stone phase of corundum phase and zirconium from learning mutually, glassy phase is filled between their crystallization.
Selected zircon sand and industrial alumina powder are pressed 1:1 and are coordinated by fused cast brick manufacturing process, additional a small amount of Na2O (adding with the form of sodium carbonate), B20:(add with the form of boric acid or borax) flux, mix, cast molding after 1800 ~ 1900 DEG C of fusings, can obtain the fused cast brick containing Zr02 about 33%.On this basis, adopt part desiliconization zircon sand to make raw material, can obtain containing ZrO2 is the fused cast brick of 36% ~ 41%.Gaogangyuzhuan zircon corundum brick (zirconia ~ corundumrefractorybrick) utilizes industrial alumina powder and selected zircon sand to be raw material, and the ZrO2 content made is the refractory product of 33% ~ 45%.Zircon corundum brick is mainly used in glass industry tank furnace.
Fused cast zirconia-alumina brick is used for the position such as flue of the little furnace sidewall of horseshoe flame furnace, crown of burner, port ramp, regenerator body of wall and alkali free glass fibre tank furnace.Above-mentioned position in use exists alternately changes fire, requires that brick has good thermal shock resistance, can sustain the impact of moment a large amount of high speed cold air; Withstand alkali steam, SO simultaneously
2with erosions such as Sodium Tetraboratees.This brick structure is fine and close, and apparent porosity is low to moderate 2%, and thus corrosion resistance is poor, cannot bear port and alternately change thermal shocking in fiery process; Brick alkali resistant or Sodium Tetraborate steam performance poor, be used in the position weak effects such as the port of horseshoe flame furnace, there is short defect in work-ing life.
The present invention aims to provide a kind of good pressure-resistant performance, the Novel fire-resistant zircon corundum brick that erosion resistance is outstanding.
Summary of the invention
The present invention is directed to the zircon corundum brick life-span of the prior art shorter, the shortcoming that erosion resistance is not good, a kind of novel anticorrosive fire-resistant zircon corundum brick is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of production method of novel anticorrosive fire-resistant zircon corundum brick:
1, raw material preparation:
A particle: granularity is the casting zirconia corundum particle of 2 ~ 4mm;
B particle: granularity is the chrome oxide particle of 1 ~ 2mm;

2, brick of preparing burden is body formed
Count by weight, by 65 parts ~ 76 parts particle A, 3 parts ~ 8 parts particle B, 10 parts ~ 16 parts particle C, 3 parts ~ 8 parts particle D, 2 parts ~ 3 parts particle E, 2 parts ~ 3 parts particle F, 1 part ~ 2 parts particle G mixes, put into mixed rolling machine, add the bonding agent of 5 parts ~ 8 parts, described bonding agent is phosphoric acid or aluminium dihydrogen phosphate, carries out mixed rolling, and the mixed rolling time is 10min ~ 15min, the material of mixed rolling is placed in pressing machine that pressure is greater than 200MPa shaping, makes volume density>=3.2g/cm
3wet base;
3, dry and burn till
Dry wet base, is placed in nitrogen kiln by dried base substrate, makes the oxygen partial pressure of firing atmosphere between 7 ~ 10Pa, ensures gas intake, makes nitrogen kiln remain on pressure-fired; Burn till 30min through 1800 ~ 1900 DEG C, then 1200 DEG C of insulations are burnt till and can be obtained for 35 ~ 45 hours, obtain anticorrosive fire-resistant zircon corundum brick.
Kyanite is one of representative region metamorphic mineral, how to form by pelyte is rotten.Under it will be formed at the higher condition of intermediate metamorphism pressure.Be present in: regional metamorphism schist and leaf gneiss and related crystal grouan and quartzy vein; With garnet, staurotide, mica and quartzy symbiosis.The kyanite of natural output, often close to ideal composition.Kyanite high temperature lower volume expands, and when the temperature decreases, volume change is very little, and being namely has non-reversibility to transform the volume-expanding characteristics produced; Stability: the refractory materials stability that kyanite is produced is higher than fireclay refractory 1.5 times; Refractoriness is high: general fireclay refractory refractoriness is 1670 ~ 1770 DEG C, and kyanite refractory materials is greater than 1790 DEG C usually, also has good resist chemical characteristic.Due to the characteristic of kyanite mineral, therefore be used for manufacturing excellent high grade refractory, refractory mortar, cement and cast resistance to goods, and plastics ramming compound, technical ceramics, the sparking plug of motor car engine, isolator, ball mill sphere, tester, shatter-proof article etc., and available electric heating process refining silumin, be applied on the parts of aircraft, automobile, train, boats and ships.
Andaluzite (Andalusite) is a kind of aluminium silicate mineral, and it is the raw material manufacturing refractory materials in sparking plug and porcelain.Andaluzite has a mutation chiastolite.The cross structure of black can be presented at the section of chiastolite.This cross structure is that andaluzite have received caused by some carbon and clay when being formed.This chiastolite is often made into the trinket that people wear.Andaluzite is generally in styloid, and its section is almost square.The crystal of andaluzite is got together into radial or granular.For the radial andaluzite of one-tenth, people are often called " chrysanthemum stone ", mean them as the petal opening of chrysanthemum.Andaluzite is pink, redness, sorrel, canescence and light green, has vitreous luster.Good and the transparent andaluzite crystal of some quality is also taken as jewel.
Float stone (volcanics) is that in volcanic eruption, magma is after hurried cooling, and due to the sharply reduction of pressure, internal gas is overflowed rapidly and expanded and a kind of glassy lava having porosity of formation.Its pore volume accounts for more than 50% of rock volume.Because hole is many, quality is light, can bubble through the water column and be called as float stone.Its feature is that intensity is high, insulation, heat insulation, sound-absorbing, fire prevention, acid and alkali-resistance, corrosion-resistant, and pollution-free, "dead" etc., float stone porous and partition is sharp in addition.Float stone is acid volcanic rock. hardness is 6, and density is less than lg/cm3, can float on the water surface; Heat insulating is good; Porous and partition is sharp.Chemically reactive is high, and adsorptivity is strong, under the effect of hydraulicity exciting agent, have obvious hydraulic gelating property.
Float stone (volcanics) is a kind of natural building material of rare, cheap production Art Stone.Current building group different style. pattern is various. to high laminar multi-model.Require that external wall decorative material has high-strength light, energy-conservation, antidetonation, weathering, moisturizing, thermal insulation, sound-absorbing, nontoxic and inexpensive feature.
Fused cast zirconia-alumina brick brick alkali resistant or Sodium Tetraborate steam performance poor, be used in the position weak effects such as the port of horseshoe flame furnace, there is short defect in work-ing life.The present inventor is surprised to find, and under specific material rate, improves the effect of corrosion resistance.
Usefulness of the present invention is:
(1) anticorrosive fire-resistant zircon corundum brick preparation process of the present invention is simple, is easy to suitability for industrialized production.
(2) the anticorrosive fire-resistant zircon corundum brick that the present invention prepares has surprising corrosion resistance, and continue corrosion at Sodium Tetraborate steam, under analog case, the life-span is unchanged more than 2 months.
(3) the anticorrosive fire-resistant zircon corundum brick resistance to compression that obtains of the present invention, thermal shock resistance is good.
