What furnace does firebrick of brick of LZ-65 tall aluminium apply to?

One, the crucial component of firebrick of LZ-65 tall aluminium is AL2O3 (3 oxidation 2 aluminium) .
By content of the Al2O3 in tall aluminous brick general component is 3 class:
Content of Al2O3 of ─ of 1 Ji ─ > 75%;
Content of Al2O3 of ─ of 2 class ─ is 65 ～ 70% ,
Content of Al2O3 of ─ of 3 class ─ is 55 ～ 60% .

Before entering to calcine of kiln of tall channel, tall aluminous brick is the move that should begin water portion to do impetuous first, the water content of tall aluminous adobe after figuration all is in normally 3.5% the left and right sides, cannot enter kiln to calcine immediately, classics needing one by one does impetuous in order to reduce water share. The system of dry impetuous regulations of base substrate because of the figuration means of base substrate different what weigh with sheet is different and different. Answer to begin dry impetuous inside desiccator of tunnel construction air with the base substrate that does law figuration partly, its warm wind is spent for 140~160 ℃ , of organic waste gas is spent answer for portion of water of remain of 60~90 ℃ base substrate under 2%

Pound dozen of figuration and the base substrate that shake figuration to want to begin nature to do impetuous first with hammer of the manual figuration that make, wind. Its are weighed because of sheet between dry impetuous different and different. Weigh the base substrate under 10Kg in the light of sheet, the nature that can begin 16~24h does impetuous: The base substrate of 10~25Kg, nature does impetuous 36~40h, it is the base substrate of 25~40kg again in the light of sheet, nature does impetuous 72~96h. Base substrate is heavier, nature should grow more between dry impetuous .

1, fireproof degree

Of brick of LZ-65 tall aluminium fireproof degree mix than argillaceous brick of half silica brick fireproof degree must tall, amount to 1750~1790 ℃ , vest in tall Ji is fireproof insulation material.

2, load molten is spent

The Al2O3 in aluminium of LZ-65 tall metal is tall, miscellaneous tone is little, the vitreous body that produces Yi Rong is little, accordingly load molten is spent taller than argillaceous brick, but because Molaishi writtens guarantee crystal did not produce meshwork, molten spends reason load to still did not have silica brick tall.

3, the sex that fight broken bits

The Al2O3 in brick of LZ-65 tall aluminium is more, press close to turns fireproof insulation material at neuter, can resist acerbity basic slag and slant of alkaline broken bits corrode, because amid contains SiO2, because this is fought,slant the working ability of alkaline broken bits is some weaker than fighting the working ability of acid slag.

4, apply heating furnace

Brick of LZ-65 tall aluminium, apply to the line in roof of blast furnace of puddling of wall of build by laying bricks or stones, hot-blast stove, heating furnace, blast furnace, reverberator, machinery. Besides, tall aluminous brick uses style heat generally store brick of hot type pane, irrigate brick of place of the head of a place of strategic importance that builds systematic software to use, water to wait. But price of tall aluminous brick should compare argillaceous brick tall, reason can accord with the area of the requirement to need not apply tall aluminous brick with argillaceous brick.

2, the brick can enter the tall aluminium after dry impetuous how to go up kiln car, car of loading of kiln chooses paper-cover normally. Be when preventing fire, cause without fine, also can choose an outfit. Use blaze kiln fire, must use get roughly into shape of tall aluminous brick. If use channel kiln fire, mesa of kiln car ambry can use chamotte sand of tall aluminous concrete to evaluate, spread among each base substrate one layer upon layer, to make bricky battlements firm, in must aspect ratio wants flat tension brick of one layer upon layer mat. The aspect ratio that load a brick is 650~1000mm normally. Brick of 3 class tall aluminium installs amid bricky aspect ratio but on the high side, 2 level of one Ji are high aluminous brick but a bit some lower.

3, the tall aluminous adobe after mount kiln car can receive tall channel to calcine is begun inside kiln, if use, is to pour blaze kiln to burn make one Ji and brick of 2 class tall aluminium normally to calcine is spent for 1430~1450 ℃ , 40h of adiabatic heat preservation. Burn when making brick of 3 class tall aluminium, fire is spent for 1390~1400 ℃ , 24~32h of adiabatic heat preservation. If use channel kiln to burn,make one Ji and brick of 2 class tall aluminium, fire is spent it is 1550~1560 ℃ commonly.

4, those who carry lukewarm rate to follow raw material and handicraft is different and different. The ultralow temperature link before 600 ℃ , ying Chi delay carries lukewarm: 600~1200 ℃ carries lukewarm rate to be able to slant fast: 1200 ℃ are spent to of the biggest fire should operate raise lukewarm rate. Even if Yi Yingcao of water refrigeration link reduces lukewarm rate.
