                                           Silicon Carbide                                                  

 

Silicon carbide, dissolved in a basic oxygen furnace used for making steel, acts as a fuel. The additional energy liberated allows the furnace to process more scrap with the same charge of hot metal. It can also be used to raise tap temperatures and adjust the carbon and silicon content. Silicon carbide is cheaper than a combination of ferrosilicon and carbon, produces cleaner steel and less emissions due to low levels of trace elements, has a low gas content, and does not lower the temperature of steel.

Q:What are included in fireproofing materials?
Incombustible material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof panel, rock wool.
Q:Does the refractory material used in steelmaking all refer to refractory brick?
The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
Q:What's the fire resistance test method of doors and roller shutters?
Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
Q:What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q:How to determine the fire resistance rating of the aluminium-plastic panel?
Fire rating of the best aluminium-plastic panel in the current market is B1 class, and its grade classifications can refer to the national standard. I have examined factories and tested the fireproof effect of the fire-proof plate myself by burning it, and I have found that the fire-proof plate of Jinwei Aluminium-plastic Panel in Linyi is really good in quality and fire prevention. In other words, from the single point of fire rating, the corresponding fire rating of the called fireproof aluminum (plastic) composite panel should be at least B class, and for A2 class fireproof aluminum composite panel, its core material currently doesn't include plastic element, so it's called aluminum composite panel which is of inorganic core material. If the ordinary aluminum-plastic panel is classified according to the fire-proof building material, it will belong to that of lower level. For aluminum-pastic panel used in business premises, it is required to reach the grade of flame retardant material or above this in fire prevention. It is expressly stipulated that its fire rating should be A2 class in public places.
Q:What kind of material is refractory bauxite?
Bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory. It must be calcined bauxite ore.
Q:What are grade classifications of the external walls fireproofing material?
1. The thermal insulation material of level A combustion performance: 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials.
Q:What types does refractory floor include?
There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
Q:What characteristics do A grade external wall fireproofing material have?
1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
Q:Which refractory quality inspection authority is good?
Download refractory quality inspection LIRR in Henan is nationally recognized. Of course, it is an authority, but the cost is very high.
