$SIC Silicon Carbide Used for Refractory and Metallurgy$

Description:

Silicon Carbide is produced by melting a mixture of silica sand and cokes in ultra high power electric furnaces. Silicon Carbide is chemically stable and has high corrosion resistance, which makes it hard to corrode from exposure to alkali or acid. Silicon carbide is also characterized by its high hardness, outstanding heat resistance, low thermal expansion, resistance to chemical reaction, and ability to function as a semiconductor.

Application:

SiC is suitable for cupola and electric furnace, widely used in iron foundries and in steel mills as deoxidizing agent, especially in ladle furnaces and electric arc furnaces during slag treatment. Silicon carbide can improve the temperature of molten steel rapidly, shorten the melting time, play the role of deoxidizing, increasing carbon and silicon, heating to improve the quality of steel.

Feature:

Black SiC, dissolved in a basic oxygen furnace used for making steel, acts as a fuel.
1.Additional energy liberated allows the furnace to process more scrap with the same charge of hot metal.
2.Silicon Carbide can also be used to raise temperatures and adjust the carbon and silicon content.
3.Silicon carbide / SiC can reduce the cost of production, produce cleaner steel and lower emissions.

Chemical Composition

Q: How long can gypsum board endure fire?: General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. It is clearly stipulated in Clause 2.0.4 of "Specification of Fire-resistance of Decoration?Design in the Interior of Buildings" that "gypsum board, mineral?wool?board and acoustic board whose combustion performance reach at B1 grade installed on steel joists can be used as A-grade incombustible materials. Although the gypsum board is non-combustible material, we need to examine materials' stability in the face of fire and their fire retardant limits besides exmine their fire prevention standards. Fire retardant limit refers to the ability and time that materials can resist fire when encounting fire and taking palce changes.

Q: What are included in wall fireproofing material?: External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincial records of production, provincial records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province!

Q: Who can tell me what is neutral refractory?: Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.

Q: How long is the fire endurance of Grade A fire resisting shutter: The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q: Is there vermiculite in refractory?: In refractory field, vermiculite is usually used as fireproof thermal insulation material.

Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: You can try the following way to give a brief introduction of the fire?rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level： Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these 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 material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: 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, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.

Q: What are the requirements when producing fireproof materials by kaolin?: . Kaolin are kaolinite crowded mineral composed of tiny flakes tubulose, lamellar smaller than 2 microns. it is composed of kaolinite, dickite, pearl stone, halloysite etc. I chemical formula of which is AL2O3-2SiO2-2H2O, the main mineral component is kaolinite and halloysite. Except kaolinite and halloysite there are other minerals montmorillonite, illite, pyrophyllite, quartz and feldspar associated. kaolin contains large amounts of the chemical composition AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and small amounts of K2O, Na2O, CaO and MgO, etc. white pottery is made of kaolin and is now internationally accepted scientific name --Kaolin, derived from the eastern suburb of Jingdezhen high-Village side of the mountain kaolinite. kaolin plasticity, cohesiveness, certain dry strength, sinterability and whiteness after burning, making it the main raw material for ceramic production;. white, soft, highly dispersed, adsorption and chemical resistance with other excellent process performance, it has been widely used in the paper industry as well as industrial sectors such as agriculture and defense cutting-edge technology in the field of rubber, plastics, refractories, petroleum refining . according to the purpose and need, it can be processed, treated and purified, they can be used to produce activated clay.

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.
