Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.

Q: What effect does aluminium powder play in refractory bricks?: Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.

Q: What defect does fused cast refractories have ?: In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are the wall brick and brick kiln bottom.

Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?: It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: What is high alumina refractory?: High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary?kilns.

Q: What is refractory aggregate?: Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.

Q: Who knows the new fireproof and thermal inuslation matertial?: New fire insulation material, having a foam material body, with the following characters: Outside of the foam material body bonds the aluminium foil composite glass fiber cloth, which is bonded by the aluminium foil and glass fiber cloth through fireproof glue. The utility model has the following advantages: Bonding the aluminum foil composite glass fiber cloth to the outer surface of the foam insulation material, will strengthen thermal insulation index, also will prevent the burning of the foamed material, thus ensuring the fireproofing safety of the foam insulation material.

Q: Who knows the fire endurance of B-level fireproof doors and windows?: According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.

Q: What is glass furnace used high-grade refractory materials?: It is said that building a furnace need 30 million? After the ignition, it can't be gone out. Only at the waste to maintenance?
