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 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...
Circular fluid-bed / construction of aerification furnace liner pledges gently of firebrick compressive strength raise a method because light qualitative firebrick makes the matter such as craft, the product that production comes out often compares tall aluminous brick in intensity or argillaceous brick is a lot of poorer, general need increases its compressive strength through a few craft. Improve light qualitative firebrick the method of mechanical function, ...
Change furnace one of crucial equipment that technical properties changes furnace is synthetic ammonia plant. As production large change, a paragraph structure more hasten is complex, heat pipe increases hundreds Ken, operation requirement requirement is strict, is average temperature in tube wall 900? 950 ℃ , operation pressure is as high as 3.9MPa(40kgf/Cm2. ) aborning controls good technology character, ...
The action of hot-blast stove lining is heat insolation is mixed bear high temperature load, the capable person that reason defines firebrick of each place lining pledges and when ply, should mix according to temperature of susceptive of place of body of build by laying bricks or stones, bear adiabatic requirement, and flue gas is decided to the condition such as the physics of body of build by laying bricks or stones, chemistry. Upside 30% ? The firebrick that the high temperature area on 40% height uses, should provide...
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, LG-O.9, LG-O.8, LG-0.7, LG-0. ...
The property tall aluminium of tall aluminous qualitative firebrick pledges one of main job property of firebrick are the structural intensity below high temperature, this one character is out of shape with loading bate temperature comes normally assess. Also determine in recent years sex of creep of its high temperature will reflect strength of structure of its high temperature. Test result makes clear, loading bate temperature follows Al2O3. The addition of content and...
Roller path kiln should consider the following when choosing light qualitative firebrick: 1. Working temperature, use temperature for a long time namely. The high use temperature of it and adiabatic firebrick is concerned. In foreign standard, high use temperature (classify temperature namely) it is to point to maintain 24h continuously its burn a line to change to not be more than the experimental temperature of 29 again, but this temperature cannot serve as...
Steel-making uses fireproof data (1) converter uses fireproof data at present bedding face of mouth of the furnace cap of converter, tapping, around, bath and hearth all use magnesian carbon brick; Trunnion and position of broken bits line use brick of high strenth magnesian carbon. Magnesian content is 70 ～ commonly in magnesian carbon brick 75 ％ , black lead content is 16 ～ 20 ％ , bulk density is 2.8 ～ 2.9g/cm3, ...
