Black Silicon Carbide for Grinding and Refractory price
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive.

- Q: What are the fire endurance requirements of class A fire resistant door ?
- Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.
- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- The fire resistance rating of the aluminium-plastic?panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic?Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.
- Q: Which kind of refractory floor is easy to use? ?
- Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
- Q: What are the characteristics of the carbon composite refractories?
- The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
- Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!
- Stable chemical properties. The crucible material should not be hydrolyzed at low temperature. It is difficult to be decomposed and reduced at high temperature and is not susceptible to corrosion by molten slag and molten metal;
- Q: What is refractory aggregate?
- It includes two categories: coarse aggregate and fine aggregate.
- Q: How many kilns using refractories are needed? What are the furnaces respectively?
- Rotary kiln, general alumina bricks, high alumina bricks, corundum - mullite brick and vertical kiln. I am limited. Please forgive me that I can only talk about what I know. There are tunnel kiln, clay brick, etc. which can be used in these kiln and shuttle kiln and so on. Shuttle kiln.
- Q: What is the fireproofing requirements of external wall thermal insulation materials?
- External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
- Q: What are fire resistant level standards of class A fire resistant door?
- Grade standards: class A fire resistant door is an important part of fire-fighting apparatus, and an important step in the social fireproof work. The quality and use of class A fire resistant door is closely related to the success or failure of the fireproof work.. There are steel and wood for class A fire resistant door materials. Only those whose fire endurance is no less than 1.5h can be called class A fire resistant door. In general, the class A fire resistant door internal material is perlite, and still some are vermiculite fireproof board, foam core board, MCcomposite materials, and other fireproofing materials. The thickness of class A fire resistant door is usually 50mm. In places where there is strict requirements for fireproof?performance, class A fire resistant door is often installed.
