Application of Calcined Bauxite:

Aluminium is a product of increasing importance for manufacturing because of its light weight, strength and durability as well as its capacity to be recycled. On a life cycle assessment basis, the high strength to weight ratio of aluminium results in significant fuel savings, particularly where substitution can be made for heavier construction materials.

 

Advantages:

1.We can control the quality and cost due to our strong capacity and cash flow in China .

2. We have strict and mature quality and logistics control on the cargo .

3.As a governmental company, we are reliable.

Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and bright, double open with glass and bright, with a bright picture, Zimu glass Zimu glass with light. Doorframe Specification: Class A, B, Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and brightness, double open with glass and brightness, double open with a lager door leaf and a smaller door leaf, double open with a lager door leaf and a smaller door leaf with glass, double open with a lager door leaf and a smaller door leaf with glass and brightness. Standard sizes: In line with GB5824-86 Hole Size of Building Doors and Windows."
Q:How long usually will the A-level fireproof materials prevent the flame?
A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
Commodity concrete stations can not be produced in general, and are made by professional fire resistant concrete manufacturers.
Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?
On the other hand, the turbulence is severe, and the side wall of the tundish is washed into the liquid steel and the service life of the lining of the tundish is reduced. In order to solve this problem, China 5%% honing develops a tundish anti turbulence pad, which is made of Al2O3>75% high alumina castable. Anti turbulence pad mounted casting ladle and tundish flow impact zone in the bottom of the flow out of the steel ladle nozzle casting hole center back in the anti turbulence pad repeatedly to consume the kinetic energy of the fluid flow, thereby reducing the steel flow speed, avoiding turbulence.
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:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
1>3>。 When metal heat exchanger is in 700 ℃, it must process high temperature protection, mixed cold wind or cold blast to protect heat exchanger. So this will waste a lot of energy; The comparison of high temperature resistant ceramic heat exchanger using temperature is 1350 ℃ to 1450 ℃; metal heat exchanger using temperature 700 ℃; heat utilization comparison of ceramic heat exchanger can be placed in 1350 ℃ or higher (highest available to 1450 ℃); the oxidation resistance, a very short time will burn out;2 >, waste heat recovery rate is high. Replacing the metal heat exchanger in high temperature and corrosion environment; Comparative ceramic heat exchanger can be used under the condition of 1350 ℃ for a long time. Let's make a comparison, if it is a refractory material industry. <, ceramic heat exchanger is simply won't appear, under the condition of equal to ceramic heat exchanger using, energy saving effect is best, can exchange for the high temperature. <. Ceramic heat can be placed on the nearest of exchanger flue outlet . <, and metal heat exchanger put in place contrast to the ceramic heat exchanger. In the process of using metal heat exchanger, if this situation happens, you can consider the ceramic heat exchanger. Temperature difference is between 650 ℃ to 750 ℃. If the metal heat exchanger is placed in normal place where ceramic heat usually put;The service life comparison: since ceramic heat exchanger with high temperature resistance, this partly replace metal heat exchanger. What's more, energy-saving rate is also different. Metal heat exchanger can be placed in 700 ℃ or less;4 >, corrosion resistance, its application effect is very different. So the metal-heat-exchanger's heat-resistant temperature is high and the service life is the countless times of metal heat exchanger. The place with highest temperature does not need high temperature protection.
Q:How long is the fire-fighting time of A class fire resisting window?
Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
Q:Fire rating of decoration materials
All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Class B2: combustible building materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
