- Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?
- Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
- Q: Who knows the setting requirements of roofing fire barrier zone?
- curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier?between?two?windows, window sill wall and skirt wall should be sealed by the fire-proof?sealing?material at each floor. I hope I can help you!
- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: Who knows about the criteria of fireproof and thermal insulation materials?
- The standards of fireproof and thermal insulation material. 1. the height of buildings is greater than or equal to 100 m, the combustion performance of thermal insulation materials should be A-level; 2. the height of buildings is greater than or equal 60 m but less than 100 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in each floor; 3. the height of buildings is greater than or equal to 24 m but less than 60 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every two floors; 4, the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every three floors.
- Q: What does the function of SiC for refractories?
- Anti-wear! High intensity!
- Q: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: Can refractory be used as sealing element?
- It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.
- Q: Is there anyone who can explain how to grade the level of fire insulation board?
- 1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
- Q: How to choose the material of refractory?
- Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
