- Q: Who knows the refractoriness of high temperature lightweight firebricks?
- Refractoriness refractory bricks with different melting points, the melting point is liquid and solid crystal phase at a temperature equilibrium. The vast majority of bricks are made of heterogeneous materials. No fixed melting point, it begins to appear to be melting and becomes complete liquid gradually, solid and liquid coexist over a wide temperature range, fusion and softening of refractory is messured by its performance at high temperature. Therefore, refractoriness is the temperature at which the multiphase reaches a certain degree of softening. Refractoriness is an important technical indicator in evaluating refractory bricks, but it can not be seen as the temperature ceiling. GB / T 7322 "Test Methods for high alumina brick refractoriness" alumina brick refractoriness test standards. refractoriness of some commonly used refractory bricks as follows: 1, clay brick 1610? 1750 ℃ ??2,silicon brick 1690? 1730 ℃ 3, crystalline silica 1730? 1770 ℃ 4, hard paste1750? 1770 ℃ 5, high alumina brickx26gt; 1770? 2000 ℃ 6, magnesite refractory bricksx26gt; 2000 ℃ 7, dolomite refractoryx26gt; 2000 ℃
- Q: What are the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- 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 many refractory materials does the annual output of 1 million tons of coke oven require?
- Refractory material is an important material used in iron and steel industry, it is mainly used in steel-making furnace, furnace lining, loading and transportation of metal and slag ladle lining, the furnace lining procedure of billet heating, heat conduction and lining of blast furnace and the flue. So, to put it simply, we can think of it as a structural material, which can withstand a temperature of 260-1760 degrees centigrade.
- Q: What are the raw materials of refractory?
- Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.
- Q: What are the common refractory insulation cotton material?
- High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.
- Q: What kind of refractories do the anode baking furnace use?
- 5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
- Q: what are the types of piping insulation material fire?rating?
- according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: Can anyone tell me what is a high alumina refractory?
- Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
- Q: Who knows the fire endurance of B-level fireproof doors and windows?
- Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
