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.
The temperature of kiln furnace is many degrees 1700 higher, even heat preservation heat proof quality is good, use tall aluminium to get together light with Molaishi light cannot have satisfied use requirement, can use flourish Cheng Naicai 0.85 exceed light qualitative alumina hollow ball brick, coefficient of thermal conductivity has 0.26 only, can satisfy high temperature and adiabatic requirement. relatively at traditional alumina hollow...
The 3 oxygen in fireproof material 2 iron (Fe2O3) content depends on normally the type of material and utility. 3 oxygen 2 iron are one of fireproof material common oxide, it can affect the function of material and fireproof performance. It is a few run-of-mill content reference below: Firebrick: Firebrick contains inferior 3 oxygen normally 2 iron content, ...
The energy-saving method of furnace of high temperature kiln basically is in centrally optimize combustion process, more than heat to reclaim use, hot project is optimized, the respect such as adiabatic heat preservation. It is a few energy-saving methods that are aimed at furnace of high temperature kiln below: Optimize combustion process: 1 use advanced combustion technology, if mix combustion, oxygen combustion to wait beforehand, in order to raise combustion efficiency and hot utilization rate. 2...
Hollow ball brick and corundum not come to alumina stone brick is high temperature fireproof material, with Yu Naigao lukewarm, anticorrosive industrial equipment liner and heat insolation. They pledge in sex of material composition, physics and apply a respect to exist a few important distinction: Material composition: Alumina is hollow ball brick: Main by alumina (Al2O3) for bases, normally...
Since fireproof insulation material applies in actual production oneself, produced its main effect, industry personnel and enterprise also threw much research, very much new product is developed in succession. The article basically elaborates the fireproof insulation material of different sort respectively from use temperature, basically be from microtherm, medium lukewarm reach high temperature 3 administrative levels...
Adiabatic and fireproof material is to point to porosity density of tall, bulk is low reach thermal conductivity low the fireproof stuff that has effect of certain heat preservation, because heat insolation is fireproof the weight of material is light, call light simple fireproof stuff again normally. One, fireproof material introduces heat insolation of commonly used heat preservation 1, fiber kind: Heat insulation board, blanket of fiber of pottery and porcelain, cotton, felt, line 2, ...
One, boiler of salt of frit of introduction of frit salt furnace is with 3 yuan or salt of binary and inorganic frit (potassium nitrate, sodium nitrate, inferior sodium nitrate the mixture that wait) to conduct heat medium, with coal, fuel or light gas to heat for fuel, use pump of frit salt loop compulsive fluid photograph circulates, after carrying heat energy the equipment that use heat, then returns the special type industry that heats afresh...
One, overview of filling technology of solder of pottery and porcelain solders the technology if electric welding, gas welding, project is plastic solder is use electric energy or solder of heat energy general and the technology that are fused together by solder workpiece. Also be one kind solders like filling technology of solder of pottery and porcelain and electric welding, gas welding technology, it is a kind of special solder technology nevertheless, it is to use farinaceous and fireproof material and noodles or vermicelli made from bean or sweet potato starch...
Change the ball of fireproof accumulation of heat of hot-blast stove needs careful operation, how to mix in order to ensure completely effectiveness. It is the move that a few need note and item below: Preparation works: Ensure to hot-blast stove is shut before beginning to change, ensure equipment refrigeration comes enough low temperature, in order to avoid scald or other and safe risk. Safety equips: Changing...
The molten iron in blast furnace, come out to shed the passageway of classics from taphole, it is trough namely, divide again among them advocate channel, broken bits channel and iron channel, advocate the function of channel is depart molten iron and broken bits, advocate the broken bits in channel from cast aside broken bits implement lintel coping enters taphole channel, namely broken bits channel, molten iron from cast aside broken bits implement passageway of lintel bottom molten iron, namely iron channeling passes, realize broken bits...
The choice of insulation material meets kiln furnace ceaseless as the change of technical development and demand evolve. Traditional light qualitative clay, tall aluminium gets together the material such as light brick was used extensively at kiln furnace heat preservation in the past, but progress as science and technology, the material such as brick of new-style small hole heat preservation also applies at domain of kiln furnace heat preservation gradually. Brick of small hole heat preservation is one kind is had...
The hot aseismatic stability of fireproof material and its composition, characteristic and preparation craft are concerned. It is the crucial factor that a few influences heat up aseismatic stability below: Composition and stuff kind: The fireproof material of different type has different hot aseismatic property. Expensive aluminous fireproof stuff, carborundum is fireproof material, zirconia is fireproof material have...
