Q:What are the raw materials of refractory concrete ?
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:How to divided the grade of external wall thermal insulation materials?
1, According to China's national standard GB8624-97, combustion performance of building materials will be divided into the following grade level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Level B2: Combustible building materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible building materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high. 2, The external wall thermal insulation materials is divided by fire rating 1) level A combustion performance thermal insulation material Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope my amswers are helpful to you
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:what grades are fire resistance of fireproofing glass divided into?
Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting roof,ceiling screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
Q:Can anyone tell me what is the material of which the mould for refractory is made?
Wooden mould will be used when refractories die is produced in small batch or composition of the refractory is complex. At the time of mass production, steel mould wil be used. The steel mould is a kind of imprint mold or cold mould. The cold mould, according to the working conditions of the products it manufactures, should have high hardness, strength, wear resistance, sufficient toughness and high hardenability. Commonly used steel types include high-carbon and low-alloy steel, high-carbon and high-chrome steel, chromium molybdenum steel and tungsten carbon chromium steel. You can choose them based on your needs
Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
Alkali resistant castables cost the least.
Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
Q:Why should graphitic refractory materials be used now that graphite can burn?
In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
Q:How much refractory material is needed when 1 million ton coke oven is produced?
