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 much is the content of boron carbide in refractory material?: Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.

Q: How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.

Q: what is the original materials of fireproof coating?: Main raw material includes high-temperature aluminum surface, expanded vermiculite,closed cell perlite, high mark number cement, Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. For example, indoor thick fire retardant coating for steel structure.

Q: who knows the requirements of refractory for forge furnace?: Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.

Q: How to classify the grade of wall fireproof and thermal inuslation matertial?: The level classification of wall fireproof and thermal inuslation matertial: Grade A: incombustible building material: Material almost with no combustion. Grade B1: nonflammable building material: Nonflammable material has good flame resistance. It is difficult to fire in case of fire in the air or at high temperature. It is not easy to quickly spread. After the fire source is removed, combustion stops immediately. Grade B2: combustible?building?material: Combustible materials have a certain flame resistance. It will immediately burst into flames in case of fire in the air or at high temperature and is easy to lead to the spread of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Grade B3: Flammable building material: It has no flame-retardant effect and is highly flammable. Fire hazard is very large.

Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.: Fireproofing glass partition has the advantages of thermal insulation,resistance slow fire spreading and smoke insulation. when the fire broke out, it can creat favorable conditions for the rescuing of personnel, property and buildings, reduce the loss to mininum level, it has gained people's favor and has huge market potential. it's widely used in computer rooms, and high precision laboratory, school,core parts of party and government organs. In the past two years, there are several major fire accidents happened in domestic, such as Shanghai jing 'an district high-rise residential, CCTV new address Beipei building, which have caused serious loss and damage. Fireproofing glass naturally become the focus, China has carried out a wide range of fire control safety inspection work, the fireproofing consciousness of people has been gradually improved. Fireproofing glass, fire-resistant glass partition, firewall, fire doors, and other products are highly emphasized. Industry analyst of Beijing Lisiduoge partition materials believes that fireproofing glass partition is a new kind of construction fire-proof material, and is mainly used for making firewall, fire doors, fire partition,etc. Europe divide fireproofing glass into composite thermal insulation type and one-side complete fireproof glass. Divided from fire resistance levels, fireproofing glass can be divided into 30 minutes, 45 minutes, 60 minutes and 90 minutes four levels. Domestic fire partition indicators in line with international standards has fully embodied the countrymen have paid more and more attention on fireproofing safety.

Q: How is the development of Xinmi refractories industry? What's its advantages and disadvantages?: The disadvantage is too small yard, vicious competition among each other and confusion in the market, which should be the inferiority of national refractory industry . Xinmi Refractory is well developed in recent years, mostly acidic and neutral refractories. It is still relatively rare to use in iron parts, steel pile with a satin and other basic refractory slide .

Q: Could you tell me the fire-resisting time of class B fire proof door?: The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
