Calcined Bauxite with Low Price 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:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:What is refractory aggregate?
Refractory aggregate is fire-resistant product improved with low temperature binder, chemical compound and normal temperature strength.
Q:What are the fire resistance ratings of the glass partition?
The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The fireproof glass is a special glass which is able to maintain its integrity and insulation in a fire resistance test. According to fire resistance performance, it can be divided into three categories: Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
Q:What refractory material lead smelting furnace needs?
Q:Refractory inquiries
Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
Q:What is special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
Q:What is the importance of silicon powder in refractory processing?
in amorphousness it is mainly the mobility
Q:Where do China and foreign countries do more refractory materials?
Zhengzhou Xinde yuan Refractories Co., the company's products have high alumina brick, clay brick, light insulating brick, wear-resistant pouring material, corundum castable, low cement castable with high strength, impervious material, material, plastic, and self shaping of various grades of cement and unshaped refractory materials. For different industries have antistripping high alumina brick, brick, alkali phosphate brick used in cement industry, boiler industry with various grades of wear-resistant brick, corundum brick, mullite brick and other forming material. Companies adhere to the "product quality for life, enterprise integrity as the foundation", in the fierce market competition, has won the trust and praise of many users. Refractory products are sold throughout the country and exported to Vietnam, India, South Korea, Pakistan, Iran and other Southeast Asian countries and regions.Companies adhering to the "quality first, reputation first, customer first" to the management of physical science, strong technical force, perfect detection means, advanced process equipment, stable product quality as the quality guarantee.
Q:What's the heat conductivity coefficient of fire-resistant material?
5~5 (Unit: W·m-1·K-1). The symbols are λ or K. Thermal conductivity and material properties Thermal insulation material generally is 0, and is related to organizational structure and working temperature. Thermal conductivity of the material refers to the heat transferred from from one plane to another plane in 1 seconds. Generally the thermal conductivity of fire-resistant material is 1. The larger the value is, the stronger the thermal conduction performance is. If the temperature of two planses differes for 1K, then the thermal conductivity is 03~1. The plane cover 1square meter.
