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.
Light qualitative silica brick and the product that pledge diatomite brick is two kinds differ gently, raw material and surface color, different. Light qualitative silica brick pledges silica brick calls silicon qualitative adiabatic brick again gently. 2 oxidation silicon is in 91% above, bulk density is in under 1.2g/cm3 pledge gently fireproof. . .
Pledge Mo Laishi brick is gently with Molaishi (the expensive aluminous simple fireproof stuff that 3Al2O3 · 2SiO2) gives priority to brilliant photograph. 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; to contain alumina taller person still contain a few corundum. Light qualitative Molaishi brick but...
According to GB/T11835-2007 " heat insulation reachs its goods with cliff cotton, mineral wool " standard, the level of surface of exterior quality requirement that sets conduit insulation material, the problem; eccentricity such as the bruise that does not allow occurrence influence later period to use, smear, damaged should not be more than 10%; normally for, structure of heat-insulating material of heat preservation of heat addition conduit basically includes...
Why should industrial kiln furnace set firebrick of build by laying bricks or stones? Kiln cylindrical shell is coil to make and be become by armor plate, what intensity of kiln cylindrical shell follows temperature is elevatory and reduce. When fire cement grog, firing take air current temperature to often be as high as 1600~1700 ℃ , stock temperature is 1450 ℃ , if do not increase protection, canister experience is burned out very quickly. The firebrick that set build by laying bricks or stones protects a canister namely...
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. The has poriferous structure adiabatic and fireproof product that basically comprises by Molaishi and vitreous photograph or photograph of glass of corundum get along with. Clay of its function excel...
What does adiabatic firebrick have? What does commonly used and adiabatic firebrick have? Because adiabatic firebrick uses temperature and the character with adiabatic heat preservation to wait for the application in industry kiln furnace in metallurgy, electric power, chemical industry, pottery and porcelain, nonferrous metal extensive. Purchase business qualitative to material when using adiabatic firebrick likelihood somewhat interrogative, below small make up for you the introduction falls commonly used...
Rotary kiln pledges with the action of brick of light qualitative wear-resisting wear-resisting brick is used at cement to answer gently if kiln is final,pass kiln face 10~15m, use at 56.2~73.2m place commonly to the kiln of 5000t class cement of 4.8*74m, use at the positional office of 45.9~59.1m commonly to the kiln of 2500t class cement of 4.0~60m. Brick of light qualitative wear-resisting has inferior coefficient of thermal conductivity and inferior...
The hot project facilities of the protective metallurgy of tall aluminous brick and other industry department, the state that has liner of brick of successive automata tall aluminium only and the system that have tall aluminous brick are protected, ability makes equipment runs reliably. The systematic safeguard of tall aluminous brick, the first pace is the thickness that liner often measures in use process. We had known to a few is plant square...
The lump heat insolation that technology of production of light qualitative brick pledges the sort of adiabatic firebrick and workmanship pledge adiabatic firebrick fastens in-house and poriferous structure to have adiabatic property gently gently is fireproof goods, it is with the production of bricky form product and application among them extensive, reason calls light qualitative adiabatic firebrick again. Light qualitative adiabatic firebrick uses raw material to be able to be divided by place pledge for clay, ...
The principle that insulation material chooses vitreous frit kiln because frit kiln the environment with located insulation material is harsher, choose insulation material to should follow the following principle so: (1) has good heat preservation performance, namely coefficient of thermal conductivity is entered λ≤0.14W/(m·K)(350K);(2) is had certain fireproof degree...
The synthetic craft of cordierite one, preparation of raw material of raw material preparation is the process that mix raw material mill and makes semifinished product. General by 3 kinds of means: ① does a law to mix, half dry method controls base. This kind of method is unwarrantable of former division fineness with uniformity, the mineral composition that short of place designs, the normal factory like — does not use this method. ...
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...
