- Q: What are the application of used refractory brick pieces?
- auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
- Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
- Volume shrinkage, uneven shrinkage and expansion of part, long-term high-temperature processing crystal type changes, calcium and other substances forming the refractory brick is Magnesium Oxide. Also the temperature changes quickly, and belongs to the crystal compound, silicon aluminum, sealing material's selection should be pay attention to
- Q: What is the refractory temperature of refractory bricks?
- First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
- Q: do the used refractory bricks pollute the environment?
- the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
- Q: How to wipe off the white paint on the refractory brick (red).
- Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
- Q: What is the density of the high alumina refractory brick?
- According to the quality, the general level is two point four to two point seven or so
- Q: What is the proportion of lightweight fireclay bricks?
- The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
- Q: The difference between fireclay brick and refractory cilica brick in the application.
- Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
- Q: The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
- There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
