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.
Founding corundum brick (RA-A) corundum namely α Al2O3, rhombohedron or board shape crystallization, true density 3000~4000kg/m3, melting point 2050 ℃ , mohs hardness 9, the systole when it is crystal 25% , apparent pore leads 10%-12% , bulk density 3000-3300KG/m3, especially the A-Al2O3 after crystallization, form a kind of faint microstructure tubal account, without Bo...
Heat preservation is able to bear or endure the application of talent skill aims to reduce steel contract for a job to make a hot loss, reduce loss of hydro-thermal of Cheng Fang steel thereby. Concerned heat preservation is carried out to be able to bear or endure on existing steel bag material technical reformation, the change that need considers to include steel space and weight is controlled the smallest, and cannot affect original build by laying bricks or stones to build technology. Through transforming, reduce molten steel Wen Jiang and...
We summed up what mine heats up furnace lining to mar basically 5 respects concern: 1, the craft parameter design of furnace itself uses fireproof material quality to build quality to concern composition of raw material of;4, fusion and broken bits composition to concern;5 about build by laying bricks or stones of;3, lining about;2, lining, with actual production the operation is concerned. 5 this when union causes lining to mar former...
The technical parameter of mine hot stove also is influence lining one of main factors of fireproof material life, 2 diameter of furnace casing of furnace of the electrode because of this reasonable configuration kiln furnace, kiln, voltage are exceedingly important. 1, extremely the influence of heart round diameter extremely heart round diameter is the craft parameter with important electric stove. If size is too small, extremely density of heart round power will be too big...
Want to buy heat preservation brick? Each province, various places all has a sale, but the price, quality is uneven, does the where of heat preservation brick of case of high quality low have those who sell? Recommend advisory flourish Cheng Naicai, material qualitative, index, dimension all but custom-built, greeting incoming telegram seeks advice, or come to a factory make an on-the-spot investigation. What is heat preservation brick? Weight is light, have heat preservation to lie between...
The adiabatic heat preservation of industrial kiln furnace is actual the effect is environmental protection one of fundamental conditions of managing the sources of energy. A kind of operating period grows research and development and can alleviate the commodity of boiler setting character is very must. Mo Laishi gets together brick of light heat preservation, have tall character the character of good, low cost, but the line in furnace of kiln of in order to, not only can reasonable alleviate boiler setting character, economic...
Hollow ball brick wants zirconia the product of fire prevention of adiabatic heat preservation that with zirconia hollow ball makes for crucial raw material. Its produce technological process is, it is raw material with zirconia, hydrogenous oxidation is calcic (or magnesian etc) make thickener, via well-balanced mix up, electric Gu law fuses frit fluid, compress gas happening with air furnace makes zirconia hollow ball, subsequently...
Boiler uses case of be in harmony of dissolve of surface layer of brick of pearlite heat preservation child vavuum pump is globose expand pearlite board the new-style heat preservation that is a kind of market application, insulation material, peng of furnace of high temperature of all previous classics is changed, surface layer shows fat plastid pattern, each grain content has persistent strong base to turn case child, give gas Kong Feng to shut type, ministry is vacuole hollow ball is tectonic. Pearlite is moistureproof...
Light qualitative firebrick can remove heat preservation heat insulation, reduce heat energy prediction of a person's luck in a given year, can rise environmental protection, managing, but the client cares about the price quite, for example: The petty gain of where of price of light qualitative firebrick? The petty gain that is normal manufacturer of course. Proportion of light qualitative firebrick, having greatest concern with the temperature of to calcine and select material, burden. ...
Float bead introduction of parameter of brick of light qualitative heat preservation floats bead brick of light qualitative heat preservation wants in order to float bead the handicraft of fire prevention of adiabatic heat preservation that is make it of crucial raw material. Float bead it is the siliceous aluminium that goes out with medium is being weighed in power plant coal ash qualitative sandwich glass is hollow bead body. Surface layer of hollow ﹑ of thin ﹑ of wall of its body light ﹑ is bright and clean fireproof performance of ﹑ heat-resisting ﹑ is good.
Heat preservation brick close, dimension concerns an a ton number and body, can have consideration through formula. Brick of qualitative light heat preservation calls tall aluminous adiabatic brick, the qualitative light fireproof insulation material that ferric oxide content makes each other by Molaishi and sandwich glass photograph or corundum in 48% the left and right sides, keys. Cubage is opposite density 0.4 ～ 1.35g/cm3. Hole is led 66% ...
Heat preservation brick belongs to the high temperature heat-insulating material in fireproof material, so, heat preservation brick has what advantage, how to select right heat preservation product, detailed introduction looks please below. Advantage of heat preservation brick 1, anti-flammability of fire prevention safety: Of heat preservation brick anthology expect those who use is to expand pearlite, heat-resisting is stuck receive a dose raw material of main mineral flame retardant, again classics science...
