- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: Application characteristics of high alumina brick
- Slag resistance. Due to the high alumina brick products in the three oxidation of two aluminum is neutral and high content, so this material products for acid-base slag corrosion resistance.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- Q: What materials are used for roof insulation?
- There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
- Q: How to reduce porosity of high alumina brick
- When proportioning, the ratio of coarse to medium to fine is 4:2:4, and the maximum particle size should be no more than 5mm. The mixing order is as follows: first adding coarse particles, then adding sulfite pulp waste liquid, premixed 3min, then adding high aluminum fine powder for mixing. The operation process is coarse and fine particles added in sulfuric acid with crushed pulp waste.In order to reduce the porosity, our company suggested that the single-sided pressure changed to double-sided pressure instead of double-sided pressure, the number of strikes should also vary according to the amount of feeding. If the kiln is fired, the location of the fire hole shall be adjusted so that the middle part is dense, the edge is thin, and the door near the kiln is properly encrypted so that the temperature difference between the furnace top and bottom and the temperature difference between the inside and outside are not greater than 20 degrees.
- 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: What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q: The difference between light high alumina brick and heavy aluminum brick
- High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.
- Q: What is the apparent porosity of high alumina brick?
- In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
