Q:For refractory knowledge. What is the ratio of clay ramming mass?
Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
Q:What are the types of steel refractory materials
(1) clay refractory brick (2) high alumina refractory brick
Q:What refractories are used in various parts of the blast furnace.
Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon carbide brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to fire endurance, fire doors can be divided into Class A, Class B and Class C fire doors, whose fire resistance should be no less than 1.20h, 0.90h and 0.60h respectively. You can use fire resisting shutters to seperate fire compartments in places where it is difficult to set firewalls. When using the fire resisting shutter with unexposed surface temperature rise as fire endurance conditions, its fire endurance should be no less than 3h. But when using the fire resisting shutter without unexposed surface temperature rise as fire endurance conditions, you should set independent protection of closed automatic water spray system at two sides of the shutter, and the duration of water spraying should be no less than 3.0h. I hope it's useful.
Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:What is refractory aggregate?
Refractory aggregate is fire-resistant product improved with low temperature binder, chemical compound and normal temperature strength.
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Wear-resistant material may or may not be refractory. Such as, aluminum oxide ceramics is both refractory and wear-resistant, and many organic wear-resisting materials are wear-resistant but not fire-resistant. First, refractory material should be refractory. It should be wear-resistant in special cases. High-temperature fluidized bed, trough, etc. need refractory material with high strength and good wear resistance.
Q:what's the application of fireproofing abs materials?
a kind of ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring, it can be processed into colorful products, also can be used as a fireproofing electrical appliance outer covering, adding alloy to it will improve its comprehensive performance, etc
Q:Which one is the best refractory material?
o make it simple, you can kindle it, and observe the burning time. If there is a professional need to be accurate, then you can send it to the professional testing company. As far as I know, the Kebiao Company over the victory bridge, Qingdao can offer professional test. I hope my answer can help you, thank you, hope to be adopted.
Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
