Product Description:

Rotary Kiln Bauxite 85. Homogenized Bauxite 88


1.Structure of Calcined Bauxite 88 Description

The products are produced by corundum and chromium oxide as main materials, formed from casting, being treated under high temperature. Reheating furnace chrome corundum slideway brick. High-speed heat flow erosion and ball dynamic conditions of wearing and tearing, and the low-melting materials under high temperature erosion, infiltration of rotary kiln body, the demanding is rigour for the refractory materials. These materials have high temperature strength, wear resistance, corrosion resistance, long-life time and other excellent properties. 

 

2.Main Features of the Calcined Bauxite 88

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. 

3.Main usage of the Calcined Bauxite 88

1) The bauxite for aluminum industry in defense, aerospace, automotive, electrical, chemical, and daily supplies;

2) Bauxite clinker processed into fine powder and made after the casting mold. Used in military,  aerospace, communications, instrumentation, machinery and medical equipment sector;

Q:What are the materials of white firebricks?
White refractory materials 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.
Q:Who knows about roof fireproofing materials?
At present, only phenolic foam boards can meet requirements. The test temperature can be 2,000 degrees, and there is no molten droplet during the tests and it can maintain integrity. heat conductivity coefficient: 0.03W / (mk), non-combustible, non-toxic, smokeless!
Q:How long is the duration of fire resistance of hollow glass magnesium board
Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.
Q:How should refractory cement be used?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
Q:What are the features of construction class A fire resistant door ?
1, Save space and reduce cost. Feature of Nanjing Cathay Class A external wall thermal insulation materials : the thickness is between 60mm--180mm, so compared with the traditional block thickness, it saves architectural space greatly. At the same time, the weight is only 1/10 of that of the traditional wall, thus reducing coast in terms of architectural structure. 2, Fireproof and green. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: fire endurance under high temperature of 1000℃ is 4 hours, and non-combustible performance can reach state A level, without any toxic gas in full compliance with international environmental standards. 3, Waterproof. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: no slightest leakage when it is being used in containers for water without any waterproof finishing. It can be used in kitchens, bathrooms, basements and other wet areas. 4, Sound insulation. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: internal materials and EPS polystyrene foam granule have good properties of sound insulation and sound absorption. 90mm-thick wall can insulate 40dB sound, in line with national standard of sound insulation for residential building. 5, Thermal insulation. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: main raw material is frezing resistant and thermal insulating material which is environmentally friendly and energy saving. With good effect of thermal insulation, it can keep indoor temperature at a constant level, so as to make the environment more comfortable.
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the requirements of Building Regulations 7.5.1 article,the fire endurance of class A fire resistant rolling shutter door should be no less than three hours.
