Compared with prior art, advantage of the present invention and positively effect are:
Common silica brick comprises the fine and close common silica brick of high-quality, and the employing silica is a main raw material, adds mineralizers such as clay, iron scale, milk of lime and produces.Common silica brick is because its violent SiO
2Crystal conversion just has very big thermal expansivity about 600 ℃, 800～1000 ℃ coefficient of thermal expansion is about 1.3～1.5%.Common silica brick can not adapt to the requirement that the coke oven rapid heating heats up and repairs, and needs just can put into production use through after the long heat temperature raising preheating.Common silica brick also owing to repair the temperature at position and sharply change, behind the several temperature period of change, is easy to generate crackle, peels off, damage and crack after repairing, and it is not good work-ing life to cause repairing the back.
Therefore the hot quick repairing of coke oven need have following several characteristics with refractory materials:
1) good thermal shock stability can not crack in the rapid heating repairing;
2) should have the chemism identical and high temperature use properties, for example high RUL with common coke oven silica brick;
3) intensity height is with the security of assurance transportation and the stability of use.
The fused quartz block that burns till of the present invention, it is little not only to have coefficient of thermal expansion, the characteristics of high thermal shock resistance, and have characteristics of high purity, high RUL, can be used as the coke oven furnace wall and damage hot patching brick when especially big area is damaged, can be rapidly heated, stand rapid temperature variation, do not produce thermal expansion, do not crack.Shorten repairing and baking cycle than common silica brick, have very high economic benefit.
It is little by (0.5 * 10 that fused quartz has a thermal expansivity
-6/ ℃), characteristics such as big, intensity height of viscosity when thermal conductivity little (0.8w/m mouth k), anti-thermal shock good stability, resistance to chemical attack (particularly acid and chlorine), high temperature.Because the hot quick repairing of coke oven requires to have the good heat resistanceheat resistant stability of shaking with refractory materials, does not crack after the rapid heating; Chemism should be identical with common coke oven silica brick with the high temperature use properties; Characteristics such as intensity height, the soft height of lotus, this is the present invention's major cause of why adopting fused quartz can be used as to produce the hot quick repairing brick of coke oven just also.
But fused quartz can form cristobalite about more than 1000 ℃, also can lose low heat expansion property simultaneously, but Al
2O
3, Fe
2O
3, impurity such as basic metal can promote the conversion of cristobalite to generate, so one aspect of the present invention control fused quartz impurities in raw materials content carries out deironing and handles, do not introduce any meeting to SiO on the other hand when batching
2Promote mineralizer and wedding agent that violent crystalline phase transforms.
The major cause of fused quartz block damage is that refractory materials in use pore is quickened its damage by intrusion.So, improve extrudate density, reduce the crystallization amount, just can improve product life.The density of goods can be controlled by following link: 1) improve the density of quartz brick green compact, it can be realized by reasonable grit grading and forming pressure; 2) select for use suitable and an amount of wedding agent, admixture with the foreign matter content in the control fused quartz block, the crystalline phase conversion of fused quartz block in burning till and using reduces and slows down; 3) strengthen and improve calcining system, goods are burnt till well.Therefore, as long as the cristobalite amount of the raw material of assurance fused quartz block and generation in burning till within the specific limits, just can guarantee the anti-thermal shock stability that it is good.
The present invention also adds the matrix composition that a small amount of silica fine powder is adjusted fused quartz block, improves the crystalline phase of fused quartz block after burning till and forms, and makes fused quartz block have the higher soft energy of high temperature lotus, repairs the service requirements of using refractory materials fast to satisfy coke oven.Silica of the present invention easily adopts the crystalline silica that impurity is few, hardness is big.
The agglutinant that the present invention adopts is SiO
2Content is greater than 96.8% high-purity soft silica micro mist.Fine silica powder is to be submicron order spheric amorphous Si O
2Particle, median size are about 0.1～0.5 μ m, have higher sintering activity, can promote the sintering of fused quartz block.When fine silica powder is heated to above 500 ℃, unbodied SiO
2Be transformed into cristobalite or tridymite, can not introduce too many impurity to fused quartz block.
The agglutinant that the present invention adopts is silicon sol, requires its SiO
2Content is at 30-50%, milky white liquid, and higher (25 ℃)≤7 Pa.S of viscosity control its sodium content.In the present invention, silicon sol produces gelation with acid-respons on the one hand, has improved the plasticity and the processability of pug, on the other hand SiO
2Micelle has improved the sintering character of fused quartz block between the 10-20 nanometer.
The present invention is by studying the influence of fused quartz block crystal transition inorganic bonding agent commonly used, find: 1) with boric acid, water glass etc. during as wedding agent, owing to introduce oxide compound, fused quartz block is subjected to the effect of mineralizer, the fierce conversion takes place in crystalline phase, generate a large amount of cristobalites, short texture; 2) use the silicon sol normal temperature strength too low merely, uncomfortable cooperation wedding agent.3) during as the wedding agent of fused quartz block, after 1150 ℃ of insulations were burnt till in 3 hours, the glassy phase of fused quartz block was still more than 90% and with phosphoric acid or aluminium dihydrogen phosphate.
The present invention adds 1～6 part industrial phosphoric acid or aluminium dihydrogen phosphate when making wedding agent, can guarantee on the one hand that fused quartz block has combination preferably and sintering strength, and compressive strength is more than 25MPa; Fused quartz block glassy phase content still remains on 90～100% behind high temperature sintering on the other hand, still keeps the low thermal expansion characteristics of fused quartz raw material, and refractoriness under load is greater than 1680 ℃.This makes fused quartz block of the present invention have that high-strength, high heat is steady, the characteristics of high RUL, can satisfy the coke oven furnace wall and damage especially big area and damage the requirement that hot quick repairing is carried out at the position.
The present invention has added white dextrin improves the lean property of fused quartz pug as softening agent processability.Discover, with other organism such as resins during, burn the back adobe and be difficult for grilling thoroughly easily and cause " evil mind ", and can cause the fused quartz block short texture as wedding agent.And white dextrin is purified by pure grain, and manufacture craft is not introduced other impurity, the ablation noresidue, and fine size is used as the moulding softening agent of fused quartz block, and effect is fine.
Accompanying drawing 1 has shown the crystalline phase conversion figure of fused quartz under differing temps.
Fused quartz block is to be the refractory materials of main raw material mechanical pressing with the fused quartz, fused quartz is in the steady state that is situated between below fluxing point (1695～1720 ℃), be unsettled on thermodynamics, when not having other oxidizing substance and exist in separating out α-Fang Shiying crystal grain (high temperature crystallization) more than 1000 ℃ lentamente, α-Fang Shiying is converted into β-cristobalite again when low temperature, volume change (2.8%) taking place, cause goods loose, peels off even ftracture and reduce its anti-thermal shock stability.
Therefore, except in prescription, selecting for use suitable and an amount of wedding agent, agglutinant to control the content of oxide compound in the fused quartz block, reduce and outside the crystalline phase of fused quartz block in burning till and using that slow down transform, the firing temperature and the sintering curve of fused quartz block controlled well is most important.
Among the present invention, owing to there is a spot of cristobalite to generate, burns till top temperature and be controlled at 1000～1200 ℃, soaking time can obtain fine and close burnt product at 2-10 hour.
