- Q:What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q:Can anyone tell me what material the first rate fire resistant door is?
- Material of Class A fire doors mainly are steel, wood, steel and wood, and other materials. Fire door is one of the measures of the building fire separation, usually used on the firewall, entrance and exit of staircase or tube well openings, which is required to hane the abilities of smoke insulation and fire insulation. Fire door plays an important role in prevention of the spread of smoke and fire and the reduction of fire loss. Therefore, we must have strict requirements. Fire doors are divided into class A, class B and class C, whose properties of fire-resistant thermal insulation and fire-resistant integrity should be no less than the following values: Class A should be1.50h; class B should be1.0h; Class C should be 0.5h. - stipulations in article 4.5.1.2 in "The New Standard of Fire Doors" GB12955-2008. I hope my answer can help you. Thank you.
- Q:What requirements should refractory materials meet?
- Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.
- 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:Who can tell me the properties and classification of insulating refractories?
- The refractory materials refers to the refractory material of high porosity, low volume density, low thermal conductivity of the insulating material. Also called lightweight refractories. It includes insulating refractory products, refractory fiber and refractory fiber products.The characteristics of insulating refractory material is of high porosity, generally 40% to 85%; the volume density is low, generally less than 1.5g/cm3; the thermal conductivity is low, generally less than 1.0W (M - K). It is used as the insulation material of industrial furnace, furnace can reduce heat loss, save energy, and reduce thermal insulation equipment weight. The mechanical strength of refractory material, abrasion resistance and slag resistance is poor, should not be used for load-bearing structure of furnace slag, furnace, and direct contact with the molten metal and other parts.
- Q:Physical and chemical indicators of various refractory.
- There are too many of them.
- Q:What kind of material is refractory bauxite?
- In China it is generally believed: "Bauxite ore refers to the mineral with a fairly high aluminum content (over 40%), and aluminum silicon ratio is greater than 2.5 (A / S≥2.5). Minerals with an aluminum content less than this value is called clay ore or allite shale or aluminious rock. " In China, it has been explored that monohydrate bauxite ore accounts for about 98% of the total reserves of bauxite.
- 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's the classification of fireproof and thermal inuslation matertial?
- 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
- Q:What kinds of refractory will be used in kiln of sintering ceramics?
- High alumina brick, clay brick, insulating brick and silicon carbide plate.
