- Q: Which industry does refractory belong to? Does it belong to construction industry?
- I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
- Q: What is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
- Q: What material is refractory material?
- Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
- Q: Which kind of furnace hearth refractory is better?
- hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
- Q: Which one is better, fire-resistant wood or steel?
- Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.
- Q: Which are roofing fireproofing material?
- (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
- Q: What are the application of old refractory bricks?
- It can be used for refractory bricks again, as long as the quality is good. It is much more cost-effective than Bayerite.
- Q: Does refractory belong to metallurgical auxiliary materials?
- Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
- Q: What are the materials of class A fire resistant window?
- Environmentally friendily, non-poisoned non-peculiar smell, non-radioactive; non-combustible, fireproof, moisture-proof, corrosion-resistant; easy to operate, lightweight, high strength, themal insulation, sound insulation; able to be cut, planed, sawed and carved. It also meets GB8624 -2006A1 level non-combustible standards. Lightweight, high strength, anti-aging, corrosion resistance; meeting the GB / T20285-2006 Opium (AQ1) safety and environmentally friendly products; Foamed fire door core board specifications: 2100 × 900 × (26 ~ 65) mm; 2050 × 850 × (26-65), and many other specifications.
