Q: Is there a big difference between two high alumina brick and one high alumina brick?: According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.

Q: Introduction of high alumina brick: Three alumina silicate refractory product with a content of two Al2O3 (48%).

Q: What is the standard classification of high alumina bricks and high alumina bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.

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: Are there any differences between insulating bricks and refractory bricks?: Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.

Q: The difference between ordinary and diatomite brick refractory brick: Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.

Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q: What should be used as binder for making high alumina bricks?: Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.

Q: High alumina brick 80 with which high aluminum cement?: In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
