- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
- Q: In 2016, a few of the traditional refractory materials will be able to survive
- In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
- Q: Introduction of high alumina brick
- Three alumina silicate refractory product with a content of two Al2O3 (48%).
- Q: How are the high alumina bricks fired?
- Light and high alumina bricks are usually fired in a weak oxidizing atmosphere. In light and high alumina bricks firing, they are often rich in impurities such as R2O, RO, Fe2O3 and so on. They react with Al2O3 and SiO2 at high temperature to produce liquid phase. In the Al2O3 - SiO2 - R2O system, the growth rate of liquid phase increases with the increase of temperature at high temperature. So, because the increase of sintering temperature brings a lot of liquid phase, the decrease of liquid viscosity will lead to the deformation of brick and the decline of brick high temperature function. Therefore, the lower sintering temperature and longer holding time should be adopted in the sintering process dominated by liquid phase sintering. The production practice shows that the same firing temperature can be used for the high grade aluminum bricks. When fired in an inverted flame kiln, it is usually 1430 degrees centigrade and insulated by 40H. The high alumina bricks such as Ill are 1390~1420 degrees centigrade. When the tunnel kiln is fired, they are 1550 and 1450~1500 degrees centigrade respectively. High alumina brick is usually made of weak oxidizing atmosphere.
- Q: What are the common thermal insulation materials for thermal conductivity?
- The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.
- Q: What is the difference between T3 refractory bricks and 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)
- Q: What are the requirements for refractory materials in heat treatment furnace?
- The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.
- Q: What's the weight of the refractory bricks?
- According to shape and size can be divided into standard brick, ordinary brick, special brick, etc.. 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 is the difference between fireclay bricks and high alumina refractory bricks?
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
- 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%.
