Q: What requirements should refractory materials meet?: The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.

Q: How to distinguish the construction fire-proof material rating?: Currently the national standards divide building materials as follows: A1, A2, B, C, D, E, F. External wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. Class A is non-combustible, class B1 flame retardant, class B2 combustible, class B3 flammable. Combustion performance grades of building materials and products are divided into class A1, A2, B, C, D, E, F. And grading of flooring materials and pipeline thermal insulation materials is also stipulated separately, whose combustion performance grade is distinguished by the subscript fl and L respectively. ie. Combustion performance grades for ordinary building materials and products are A1, A2, B, C, D, E, F; combustion performance grades for paving material are Alfl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl; combustion performance grades for pipeline thermal insulation material are A1L, A2L, BL, CL, DL, EL, FL.

Q: What are the refractory materials above 1000℃: It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .

Q: Who knows the fire rating of fire?partition with steel stud?: Partition system made by fire?partition with steel stud and high-quality keel has good fireproofing performance and is non-combustible sheet. Flame burn duration is zero. It does not burn at 800℃, and it is without flame at 1200℃. Its fire resistance rating reaches GB8624-A standard through test, which reaches the highest fireproofing and non-combustible level grade A1. 10MM fire endurance can reach up to 4 hours fire resistance maximum limit. It can absorb a lot of heat during the process of burning and delay the rise of temperature in surrounding environment.

Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?: Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)

Q: How many refractory materials does the annual output of 1 million tons of coke oven require?: The production of dense synthetic Magnesium Oxide requires many steps, briefly summarized as follows:(1) Mgcl2+Ca, Mg (OH) 2, =Mg (OH) 2+CaCl2Sea salt or brine, dolomite, magnesium hydroxide, residual salt(2) Mg (OH) 2 Mg0 (low density);(3) MgO, Mgo (compact)The resulting compact Magnesium Oxide generally has a purity of up to 95%-99%, depending on the manufacturing process and the final application requirements. As shown above, Magnesium Oxide can be obtained from sea water and slaked lime. The density of the final product is through the high temperature roasting in shaft furnace and the large area obtained by calcination, and the mechanical compaction. Through the pre sintered refractory material to fundamentally eliminate the permanent contraction or extension is extremely important, it is obviously, because we cannot expect excessive contraction or extension in the use of the materials can be used to store the proper degree of molten metal or slag. The production of magnesium oxygen throughout the world (Fang Meishi) large factories in the United States, Michigan by brine well production, and by the sea water production Magnesium Oxide factory is located in Florida, Texas, California and Maryland.

Q: How to divide the fire rating standards of insulation materials?: 1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.

Q: What materials are needed to make the amorphous refractory bricks?: Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.

Q: Which kind of external wall fire barrier zone material is better?: I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.

Q: What are first rate fire resistant window materials?: Natural environmental protection, non-poisoned, non-peculiar smell, non-radioactive; non-combustible, fireproofing, moisture-proof, corrosion-resistant; easy construction, lightweight, high strength, www. jsxsmy.
