In the same condition, using manganese or silicon to deoxidize separately, the burn out rate are 46% and 37%, but it is only 29% if using manganese alloy to deoxidize. So, it is used widely to smelting steel and its output increases faster than ferroalloy's, so has become an indispensable composite deoxidizing and alloy additives in steel industry. The silicon-manganese which contains carbon below 1.9% still is used to produce medium/low-carbon ferromanganese and semi-finished products of electro silicothermic process manganese metal.

Q:What kind of refractory bricks material is best?: It depends on your purposes. In general, aluminous fireclay brick is usually used. GB/T 3994-2005 insulating fireclay brick. Bricks with good textile are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.

Q:Who knows what kind of fire protection material is better?: Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)

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:What does fire-resistant insulation coating have?: Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature.

Q:How to make fire resistant materials for building stoves: Grand Theft Auto Vice City plus life code is what?

Q:Preparation of refractory clay: Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.

Q:Can you tell me the classification of fireproof sealing material.: Organic fireproof sealing material include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. Organic plugging material take organic materials as the adhesive with certain flexibility or plasticity when used. The product is thick liquid or cement. Inorganic plugging material take powder of solid inorganic material as the main ingredients, and admixture mixed use, with proper workability. Fireproof bag apply bag shaped object made up by fire-proof materia to large hole fire plug or cable tray fire compartmentation (fire package also called as refractory package or fire protection package). Fire modules is made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. fireproof sealing material is the plank made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. Foam block after injection holes can lathery foam and seal hole. Sealing strip is made of fire prevention materials with certain geometry shape or flexible coil geometry.

Q:how is the high-temperature flame-retardant fibre board?: The market is mainly divided into three kind of fiber. Density fiberboard, medium density fiberboard, high density fiberboard. Density fiberboard: It is rolled timber sheet made of wood shaving material produced by timber or non timber fiber that is added with or without glue or auxiliary material. A density of less than 450 kg / cubic meter, the larger fiber particles, the internal structure is not homogeneous, relatively lack of strength, lighter weight. MDF: use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. A density between 450-880 kg / cubic meter, fiber particles is moderate, well proportioned internal structure, greater strength, moderate weight. HDF: Use wood fiber or other plant fiber as material, added with glue. A sheet pressed at high temperature and pressure. Its density is about 880 kg / cubic meter, small fiber particles, well proportioned internal structure, greater strength, greater weight. there are also artificial boards such as chipboard and melamine board in the market, generally used for making furnitures. the thickness of fiberboard that is produced and controlled more flexibly, is generally 5 per cent (general bulk price of 30 yuan per square meter), 9 cm (50 yuan), 18 cm (100), 25 cm (120), etc. There are thicker. However, proper deviation is acceptable. The board is usually thicker or thinner than the specified thickness. For example, It is only 16mm when specified 18mm.

Q:What are the additives and recipes of refractory?: Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).
