Q:what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.

Q:What kind of refractory bricks material is best?: Domestic experimental electric furnace body is made up of hearth, insulating layer and shell. Sic and high-alumina material are often used in traditional electric furnace under 1300℃ traditional furnace, while corundum material is used in 1600℃. Laboratory furnace of Occident usually uses ceramic fiber tank which is characterized by rapid temperature raising, good accuracy, light weight and small volume. In recent years, domestic Hangzhou blue sky Instrument and Shanghai laboratory equipment all have been produced by experimental furnace with ceramic fiber tank.

Q:Can anyone tell me what is A-leve fireproof material?: Combustion performance of materials can be divided into: A-level, B1-level, B2-level and B3-level, which respectively refer to noncombustible, difficult-flammble, flammable and inflammable materials. Building materials can be divided into four grades based on combustion performance (noninflammability, flame retardancy, flammability and inflammability). According to the stipulation of "Specification of Fireproof Design for Buildings" (GBJ16-1987) (2001 revised edition), fire hazard of production or storage should be divided into A-level, B-level, C-level, D-level and E-level. In "Specifications on Fireproof Design for Petrochemical Enterprises" (GB50160--1992) (1999 Revision), it also stipulates that fire hazard should be classified on the same basis of subtsance danger in usage, production or storage. According to different fire hazard, requirements and measures of oreventing and restricting fire explosion can be put forward from the aspects of fire?separation distance, fire resistant rating of buildings, allowed floors, safe evacuation, fire fighting facilities and other aspects.

Q:Which brand of AAA refractory is good?: The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory?aggregate and porous refractory?aggregate, organic fiber and inorganic fiber.

Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?: 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3

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 fire resistance ratings of the glass partition?: The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The fireproof glass is a special glass which is able to maintain its integrity and insulation in a fire resistance test. According to fire resistance performance, it can be divided into three categories: Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.

Q:What's the texture of refractory for the hearth of reverberatory?furnace? ?: The long-term usage temperature of ceramic fiber is between 950-1260 degrees.

Q:Who knows about the grade C fireproof door materials?: There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire?rock?wool?boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.
