Product Description:

1. Structure of Calcined Bauxite Description

Natural Bauxite of  Bauxite Refractory CNBM in China with Size 1-3mm

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite; main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. The color is white or gray, brown and yellow or light red by iron.  From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle, very difficult to melt.  Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material. 


2. Main Features of the Calcined Bauxite

Natural Bauxite of  Bauxite Refractory CNBM in China with Size 1-3mm

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 removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns.

Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
I’d like to make supplements to upstairs that aluminum silicate refractory materials should be needed considering heat insulation.
Q:Which manufacturers have the best fire-proof materials with light weight?
Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.
Q:What are the best refractory materials in 2,400 Celsius degree?
and carbon fiber or nanomaterials.
Q:Why do magnesium oxide refractory bricks can be made into refractories?
Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.
Q:how does the fire endurance of first rate fire resistant window?
Not less than 1.5 hours
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:What is the fire endurance of ceramsite concrete blocks?
What is mentioned in fire safety rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated concrete block" DB / T29-128.
Q:Which are fireproofing external wall materials?
According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.
Q:What is the principal part of silicious refractory material
blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
Q:What kinds of fireproof and fire retardant materials are there?
general classification of fire retardant materials will use A, B in the home improvement supplies. A has the best flame resistance, followed by B.
