Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Pledge Mo Laishi brick is in firebrick again, the tall aluminium that gives priority to brilliant photograph with Molaishi pledges we weigh fireproof material for Mo Laishi brick, cent is attached most importance to pledge and pledge gently. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; Contain alumina taller person...
Alumina is hollow ball brick is the adiabatic and fireproof product that with alumina hollow ball makes for main raw material. It basically uses as the heat preservation thermal insulation of the liner of furnace of kiln of high temperature industry under 1800 ℃ and facilities of expensive tepid work. Alumina is hollow the aluminous content of ball brick is more than under 98%SiO2 content 0.5% , fe2O3 content is more than 0.2% , ...
It is in the contemporary industry with mineral products increasingly nervous resource, the refractory products of managing environmental protection becomes hot industry business to compare gay product, the use of light qualitative adiabatic firebrick with each passing day grow in quantity. The defect of light qualitative firebrick is difference of heat proof quality, the advantage is long-term high temperature resistant function is very good. In use can reduce the weight of kiln body, reduce thereby...
Tall aluminous qualitative adiabatic firebrick (light qualitative tall aluminous brick) , alumina content 50-56% , bulk density 0.6-1.2g/cm3, 25 ℃ of ± of W/m.k(350 of coefficient of thermal conductivity) 0.25-0.45, use temperature is as high as many degrees 1300, from these data can see, this product adiabatic fireproof. Tall aluminous qualitative adiabatic brick is give priority to with aluminous alumina should former...
Fireproof light qualitative energy-saving brick is with firepower power plant fly ash floats mediumly bead for main raw material, join right amount binder and auxiliary material, uses auxiliary data basically is Yang Quan's saggar its are fineness and all sift through 100 eye. Next, via mixing even hind, suppress shapes, high temperature to calcine and a kind of when become light qualitative fireproof heat preservation is produced...
As the progress of content of the Al2O3 in Mo Laishi brick, function of its high temperature progresses, and frit dosage grow in quantity, high temperature function is reduced. Accordingly, control content of foreign matter oxide strictly, especially the content of K2O, Na2O and Fe2O3, it is to obtain tall function the important step of Mo Laishi brick. In contain alkaline of kind of composition slaggy or make in gas atmosphere...
Porosity of light qualitative tall aluminous brick tall, thermal conductance sex of small, heat preservation is good and have particular compression strength, with thermal conductance low, thermal conductance is 0.291-0.582w/(m.k)(350 ℃ ) , the material of construction of body of heater with small thermal capacity, can save specific fuel consumption; In the meantime, because kiln furnace can rise gentle refrigeration quickly, can raise equipment to manufacture efficiency; ...
Light qualitative tall aluminous firebrick belongs to heat preservation brick, have brick of light qualitative clay low-costly, heat preservation performance is strong basically see coefficient of thermal conductivity, performance of lower heat preservation is stronger. Light qualitative tall aluminous firebrick pledges tall aluminous brick calls tall aluminium adiabatic brick again gently. Alumina content is in 48% above, main pledge gently by what Molaishi and vitreous photograph or corundum comprise jointly fireproof...
Kiln furnace heat preservation is energy-saving can protect an environment already, also can reduce caloric waste, how to come true? Use light qualitative adiabatic and fireproof data, for example heat preservation brick, heat preservation is pouring cotton of makings, heat preservation is waited a moment, it is OK to need those who pass liner to transform a design to come implementation heat preservation is energy-saving. Light simple adiabatic and fireproof stuff is to point to porosity density of tall, bulk...
Vitreous kiln differs with what pledge heat preservation brick presses its raw material gently, can divide for 6 kinds big. Its application pledges gently to be extensively silica brick, diatomite brick. Brick of light qualitative heat preservation has the advantage with adiabatic good performance, but the compression sex, sex that fight broken bits, heatproof shake sex is poorer, reason cannot be contacted directly with vitreous fluid or blaze. 1, light qualitative silica brick. Light qualitative silicon is qualitative...
Mo Laishi pledges adiabatic brick is to point to gently with aluminous, clay, " 3 stone " etc for main raw material, through be in material shapes or the interior in process of high temperature agglomeration forms the hole that each other connect or closes in great quantities. As a result of its taller hole is led, have inferior coefficient of thermal conductivity consequently, originally plus Molaishi some is high temperature resistant, heatproof shake is stable...
Henan tall aluminium gets together light brick is fireproof degree of tall, use temperature is high, the heat preservation that basically is used at furnace of high temperature kiln is adiabatic, it is the light qualitative firebrick that has heat insulation of fireproof, heat preservation. Tall aluminium gets together light brick calls brick of light qualitative tall aluminous brick, tall aluminous heat preservation or tall aluminium adiabatic brick again, it is to show AL2O3 content is in 45% above all sorts of light qualitative firebrick. Light qualitative tall aluminous brick is used...
