Hot Sale Calcined Bauxite  Made in China

Introduction of calcined bauxite

Calcined bauxite is one of the principal ore of aluminum.

Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .

Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .this can removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 75% to 90%.

Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).
Q:How to classify fire resistance rating of brick-concrete structure?
In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
Q:what's the fire endurance of fireproof panel?
Fire endurance of fireproof panel is 3 hours, for example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. Fireproof board, also called fire endurance board, scientific name is thermosetting resin impregnated paper laminated wood.
Q:As for fireproofing material rock wool and glass wool, which one is better?
As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:How much is refractory spraying coatings?
Different brands and models have different prices. For example: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Hengli | Product category: dedicated castable for biomass burning machine | Material: castable Price: 3000.00 refractory temperature: 1770 ~ 2000 ℃ | Brand: Great Wall | Category: unshaped refractory material | Material: corundum mullite Price: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Guanghuayaoye | Product category: refractory material| Material: high alumina Price: 2500.00 The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
Q:Who knows the fire rating of fire partition with steel stud?
1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
Q:Is the ball mill used in production of refractories?
It will be used. It is used in the process of milling the raw material which is less demanding on technology and in relatively large amount. Is there lots of network marketing for refractory industry? Is the competition fierce on the Internet?
