7. Being all kinds of unshaped refractory materials and fireclay of high temperature industrial furnace
- 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: What are the grades of high alumina bricks?
- According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
- Q: What are the specific raw materials for plastic pallets?
- With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
- Q: Density of high alumina bricks
- High alumina brick by aluminum content is divided into four grades, three grade high alumina bricks content of not less than fifty-five percent, two grade high alumina bricks content of not less than 65, a high aluminum brick content of not less than 75, super high aluminium brick content above 85. As for the high aluminum brick shape, in addition to the standard high alumina brick, high alumina brick and general type, also called special high alumina brick, if the shape is very irregular it is usually called the specific type of high alumina brick, in short, to customized according to the specific use of kiln.
- Q: Which is better, the soft core or the hard core?
- The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.
- 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: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is fired at 1300 - 1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, 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.
- Q: What causes breakage of refractory bricks?
- There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
