Q:What are the characteristics of high alumina bricks?
The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
Q:Aluminum content 38. silicon content 55 What refractory bricks?
Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite
Q:How to reduce porosity of high alumina brick
High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!
Q:What are the common thermal insulation materials for thermal conductivity?
The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
Q:Application characteristics of high alumina brick
Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.
Q:Introduction of high alumina brick
Three alumina silicate refractory product with a content of two Al2O3 (48%).
Q:What's the difference between a well type annealing furnace and a box type annealing furnace?
Box annealing furnace application: mainly used for quenching, normalizing, annealing and other conventional heat treatment equipment for steel parts. Features: 1, electric loading, high productivity, heat treatment is especially suitable for small and medium-sized parts, such as 30%, uniform temperature, intelligent digital display meter PID (pictured) automatic temperature control, high precision; 2, electric discharge loading convenient, as good; 3, door and seal the oven body is sealed automatically, without manual seal; 4, equipped with electric interlock protection device, and can prevent the fault accident due to the error. Bell type annealing furnace four bell type annealing furnace bell type annealing furnace is mainly used for annealing sheet metal in natural atmosphere and normalizing treatment of steel parts. 1, special steel, precision alloy large all fiber trolley type resistance furnace, strip, wire bright annealing. 2 、 annealing of special steel casting and forging. 3. Annealing of silicon steel sheet. 4, metal and non metal powder sintering pieces etc..
Q:What are the high temperature refractory mortars made of?
Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.
Q:How are the grades of high alumina bricks differentiated?
High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
Q:What is the difference between T3 refractory bricks or high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
