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:What is the high temperature limit of refractory bricks and refractory soil?
According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
Q:The difference between aluminium refractory and magnesia refractory
Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
Q:What are the alloy wear resistance materials?
According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
Q:What is the standard size of high alumina brick?
Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.
Q:How does the physicochemical index change when the high alumina brick is used at high temperature?
If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
Q:What are the specifications for bricks?
Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
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 is the standard classification of high alumina bricks or 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:Refractory brick, high alumina brick, magnesia chrome brick or magnesia brick, clay brick, which type of high temperature refractory brick?
The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
