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: Who knows what is the requirement for fireproofing of interior decoration materials ?: In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.

Q: What kinds of refractory will be used in kiln of sintering ceramics?: High alumina brick, clay brick, insulating brick and silicon carbide plate.

Q: About the market issues of thermal insulation material and refractory material.: In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu

Q: What is the role of the vermiculite fireproof material?: It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.

Q: Which brand of AAA refractory is good?: Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.

Q: What are the fire resistances of grc partition panels?: Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls.

Q: What is the acceptance standard of refractory?: Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.

Q: What are the disadvantages of the refractory industry?: The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
