Q: How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q: Who knows the model of fireproofing materials?: There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire?rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.

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.

Q: Concrete composition and function of magnesia bond used in refractory: According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..

Q: What are the new refractories? What are the features? How about their application and development?: In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.

Q: Does refractory belong to stone, building materials or other?: It belongs to metallurgy and building material industries.

Q: How long is the fire-resistant time of fireproof wooden door?: The fire-resistant time of fireproof wooden door is about 1 hour. Fireproof wooden door refers to the door whose door frames, skeleton of the door leaf, door panels are made of timber or timber work and fire endurance reaches the provisions of "GB50045-95 design of tall buildings for fire protection". Fireproof door is one of devices for fire?prevention and separation of the building, generally used on the firewall, entrance and exit between stairs pipe shaft opening, which plays an important role in the reduction of fire losses.

Q: What is required to do refractory material?: But we can’t exclude that some products may contain a certain amount of metal materials: refractory material is non metallic materials whose physical and chemical properties make it suitable to be used under high temperature. Technically, it needs high purity raw material,high pressure molding, high temperature sintering to make refractory material. Refractory materials have two properties: first, the strong thermal shock resistance, second is slag resistance, the key is to look at what parts does it apply.

Q: What are the characteristics of clay refractory materials?: Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.

Q: What are the requirements when producing fireproof materials by kaolin?: Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
