Tall aluminous qualitative adiabatic firebrick uses clinker to be earth of tall aluminous vanadium and clay of raw material union to be made, have good heat preservation heat proof quality, reduce heat energy prediction of a person's luck in a given year. Tall aluminous qualitative adiabatic brick is the Al2O3 content that controls for main raw material with aluminous alumina do not be less than the adiabatic and refractory products of 48% . Its produce craft to use bubble method, also can use burn oneself out to add content way. Chinese standard (GB3995, 1983) presses tall aluminous adiabatic brick bulk density cent be LG-1.0, a variety of brands such as LG-O.9, LG-O.8, LG-0.7, LG-0.6. The influence of combustion and fuel nozzle to firebrick, when making fuel with coal, the volatilization of coal is divided and ash content is having conclusive effect, affect blaze figure directly. General component is firebrick two kinds, do not finalize the design namely fireproof material and finalize the design fireproof material. Adventitious fireproof material: Also cry pouring makings, be mix a kind by a variety of aggregate or collect makings or a variety of sticking and the mixture that the agent comprises is farinaceous a makings, one kind is mixed when using or a variety of liquids cooperate agitate even. Firebrick has strength tall, fight wear away, fight erode conserve does not need to be able to throw the characteristic such as production instantly after ability reachs construction by force. Product use: Extensive and applicable pledge than clay and tall aluminous qualitative adiabatic firebrick is complex, turn in material of adiabatic line fire the place in total output holds proportion very small. Firebrick is in its production process, its change physico-chemically to was not achieved commonly firing the balance position below temperature. Also have firing inadequate firebrick, suffer again in rotary kiln action consequently when high temperature action, to maintain the integral sex of boiler setting and firm sex, take every other 5 ～ 8, in bricklaying layer height the place of identical coincide, wall of inside and outside pulls the build by laying bricks or stones of solid to build a way each other, be about to the half of firebrick inserts another brick layer in, or with metallic anchor firmware is secured. The respect such as industry of ceramics of abrade industry, chemical industry industry also has saggar main use. Most firebrick reachs the fill of hole as a result of the generation of photograph of its itself fluid, happen not reversible burn systole again. Accordingly, stability of high temperature bulk, in choose firing when taking firebrick, give consideration. The main effect of rotary kiln firebrick is the harm that protects kiln cylindrical shell not to get high temperature gas and high temperature stock, assure manufacturing on the rails. In industrial production, firing the service life that leads firebrick is very brief, kiln overhaul stops outside often causing a plan, it is influence cement kiln high quality, high yield, low cost is mixed the crucial factor of year of movement rate. Technology of production of tall aluminous qualitative adiabatic brick introduces tall aluminium to pledge adiabatic firebrick uses clinker to be earth of tall aluminous vanadium and clay of raw material union to be made. If use mix into to make alumina contain li of tall aluminium that is 50%-60% into combustible law,pledge when adiabatic firebrick, earth of tall aluminous vanadium deserves to compare with what combine clay for 40-50% and 50-60% , outside adscititious 20-25% curium wood chip, mix even hind tired makings 24 hours, with but model law shapes, in 1350-1380 ℃ firing. The property of its goods is 0.8-1.35g/cm3 for firebrick bulk density, compression intensity can amount to 294-588N/cm3, porosity amounts to 50% above. It is a kind of good high temperature heat insulating materials. Qualitative adiabatic firebrick can use product application tall aluminium at build by laying bricks or stones to build thermal insulation and erode without division of content of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, the temperature of watch surface contact of general tall aluminous qualitative adiabatic firebrick does not get prep above 1350 ℃ . Mo Laishi pledges adiabatic firebrick can contact blaze directly, have high temperature resistant, intensity is high, energy-saving effect is distinct wait for a characteristic. Apply to roller of the furnace that heat up solution, hot-blast stove, pottery and porcelain kiln of drawer of porcelain of path kiln, report and the liner of all sorts of resistor furnace. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
