Q:How long is the fire endurance of Grade A fire resisting shutter: Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.

Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?: I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.

Q:Does anyone know what is a lightweight refractory material?: The volume shrinkage is larger, and the corrosion resistance is higher at high temperature. A lightweight refractory material, used as thermal insulation material in industrial furnace and other thermal equipment, has poor wear resistance, weak mechanical strength and small volume density. Compared with ordinary refractory bricks, the lightweight refractory with low thermal conductivity has higher porosity.

Q:what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q:What kind of refractory materials are used in metallurgy industry?: Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.

Q:What are the standards of refractory concrete ?: Heat-resistant concrete refers to the kind of concrete which remain undamaged, do not lose the necessary bearing capacity at 200 ~ 1300 ℃ high temperature for long term, and still maintain its physical and mechanical properties.

Q:Can you tell me the classification of fireproof sealing material.: Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.

Q:How to hang the suspended brick in the refractory masonry?: First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.

Q:What is the function of refractory material?: Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
