- Q: How much is the bending temperature aluminum silicon carbide brick for torpedo car
- 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 hot blast stoves.
- 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
- Refractoriness. High alumina brick products are advanced varieties of aluminium silicate refractory products, and their refractoriness increases with the increase of Al2O3 content, generally not less than 1750 - 1790 DEG C. If the content of Al2O3 is more than 95% of corundum brick, the refractoriness can be as high as 1900-2000 degrees.
- 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: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
- Q: Can high alumina brick resist carburizing?
- The key is to look at the content of Fe3O2 metal oxides (so-called anti carburizing brick generally refers to the content of Fe3O2 less than 1% clay brick and Gao Lvzhuan) just a photo shoot, out for everyone to see, high alumina brick common in reductive atmosphere has been chalking up.
- Q: What are the characteristics of high alumina bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. 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, brick, brick and other specific type. 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. For example, refractory clay brick, high alumina brick, brick, brick etc..
- Q: What does refractory consist of?
- According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- Q: What is the difference between metal compounds and metal solid solutions?
- Solid solution refers to the alloy phase in which the solute atoms are dissolved into the solvent lattice and remain solvent type. A crystalline substance consisting usually of atoms or molecules in which a chemical substance is dissolved as a base; other substances are found in alloys and silicate systems; also present in polyatomic substances. The mixture can be treated as a solution when the crystal structure of the solvent can be stabilized and homogeneous after addition of solute. Some mixtures can form solid solutions in many concentrations, while some mixtures do not form solid solutions at all.
