Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
Q:Does the refractory material used in steelmaking all refer to refractory brick?
For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.
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:How to divide fire resistant level of fire door?
The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
Q:Which fire-resistant materials have good viscidity?
Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Class B2: combustible building materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
Q:What are the physical properties of refractory material?
The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
Q:What things and cement mixed can act as refractory?
Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
Q:Which are fireproofing external wall materials?
1. Acording to national standard GB8624-97, the combustion performance of construction materials are classified as: Grade-A: incombustible building material: Grade-A WW thermal insulation material which hardly burns. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is difficult to burn or spread in the air or at high temperature. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is easy to burn in the air or at high temperature, thus spreading the fire, such as wooden column, timber roof truss, timber beam and wooden stairway. Grade-B3: inflammable building material. Without fire resistance, inflammable building material is easy to burn and thus cause a fire. 2. According to fireproofing performance, external wall thermal insulation materials can be classified as: 1. Thermal insulation material with Grade-A combustion performance: WW inorganic thermal insulation material, rock wool, glass wool, foam glass, foamed ceramics and foam cement. 2. Thermal insulation material with Grade-B1 combustion performance: XPS panel after special treatment/ PU, phenolic aldehyde, gelatine powder polyphenyl granule after special treatment. 3. Thermal insulation material with Grade-B2 combustion performance: EPS, XPS, PU, PE, ETC.
Q:What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
