Usage:

(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry,

daily necessities, etc.
2 precision casting. Alumina clinker made after the mould precision casting processed into fine powder.

Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong,

and good physical properties.
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability,

low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock.

Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy,

defense and other industries.
(5) in magnesia and bauxite clinker as raw materials, add the appropriate binder,

used for pouring ladle whole ladle lining has particularly good effects.

Q:What are the specific steps of stirring the steel ladle castable?: Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.

Q:Who knows what is the standard of insulation material whose fire proof is level A?: Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.

Q:What is refractory brick?: Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.

Q:Who knows how many fire heat preservation material are there?: Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.

Q:How many types of fire-resistant material?: 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.

Q:Who knows the refractoriness of high temperature lightweight firebricks?: The disadvantage of light refractory bricks is its poor thermal insulating ability and the advantage is its endurable heat resistance property. The temperature range and main features of thermal insulation refractory are as follows. Diatomite brick

Q:What type of firebrick does TZ-3 represent?: Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).

Q:What are first rate fire resistant window materials?: class A window not less than 1.2 hours, class B window not less than 0.9 hours, Class C window not less than 0.6 hours. technical requirments: 1, materials and accessories (1) the window frame is made with a certain strength sufficient to safeguard the integrity and stability of the steel frame or wooden frame. (2) steel frame and mound layer can choose the galvanized steel plate or stainless steel plate. Its selection standards is in line with GB12955 "Steel Fireproof Door General Technical Condition" provisions of Article 5.1. (3) wood frame and mound layer material selected from the standard should be consistent with GB14101 "General Technical Conditions of Wooden Fireproof Door" in the provisions of Article 5.1.1. (4 ) steel, wood frame the inside filler material should be incombustible material. (5) fireproofing glass can be used without affecting the fire windows fire resistance test approved product. light transmittance of glass should not less than 75% of commom sheet glass which is the same number of layers. ( 6) a sealing material between the frame and the fire-resistant glass flame retardant materials should be used, which can play the role of fireproofing and smoke insulation in case of fire (7) hardware fitting should be tested as approved supporting product

Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?: The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic

Q:What are the materials of insulation firebricks?: The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
