Product Description:

1.Structure of Calcined Bauxite Description

There are several different models of calcined bauxite,we own have three bauxite quarry,and can  produce 5000 tons bauxite per month.

The price of calcined bauxite based on the quantity and the type, pls kindly go through the following presentation,and just tell me which type you want to buy, what is the application and how many, then we can quote you correctly! 


2.Main Features of the 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 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

Bauxite is widely apply to refractories, aluminum silicate refractory fiber, precision casting, alumina smelting industry,bauxite cement,construction materials, etc.

Q:How long is the duration of fire resistance that fireproof door of level B can endure?
Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof door. Fireproof door of level A can endure fire for 1.5 hours while level B 1.2 hours
Q:Why the corundum can be used as refractory
Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful
Q:What's the heat conductivity coefficient of fire-resistant material?
There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
Q:who knows the requirements of refractory for forge furnace?
Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
Q:What is the importance of silicon powder in refractory processing?
it can certainly improve the fire resistance
Q:how to classify Insulating Refractory ?
Low-temperature thermal insulation materials (less than 600 degrees Celsius): medium temperature thermal insulation materials such as diatomaceous earth, asbestos tile (600-1200 degrees C): high temperature thermal insulation material vermiculite, light clay bricks(greater than 12,000 degrees Celsius): Lightweight corundum brick raw materials: Clay, high aluminua, silica, magnesia
Q:Who knows the model of fireproofing materials?
There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
First, it is prohibited that the thermal insulation material of level B2 and below combustion performance is used in the thermal insulation project of any civil building wall, and the thermal insulation material of below level A combustion performance is used in the thermal insulation project of curtain wall civil builduing that the height is equal and greater than 24m, of non-curtain wall residential building that the height is equal and greater than 100m and of other non-curtain wall civil builduing that the height is is equal and greater than 50m. Civil builduing wall thermal insulation project must strictly enforce the "civil builduing external wall thermal insulation systems and external wall decoration fireproofing interim provisions" (referred to as "fireproofing interim provisions").
Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
ShiLiDe materials are relatively poor, and have nothing to do with 3M at all. 3M is a brand! 3M company is famous for innovation around the world. It has developed a variety of products in a hundred years, involving in automotive, chemicals, telecommunications, construction and other fields. 3M automotive aftermarket has more than 3,000 products (more than 20% of which are high-tech patented products). The world's first explosionproof and heat insulating film, and the first waterproof abrasive paper were born in 3M Company. The abraser, polishing materials, mirror finish of paintwork, the internal and external auto beauty of 3M Company rank the first place in the world. 3M films are divided into conventional films and crystalline auto films. The conventional films of 3M generally have five-layer structure, the base of films is a polyester film which is s plastic film of tearing and puncture resistance. The film is coated with thermal insulation layer, ultraviolet isolation layer, adhesive layer, wear-resistant layer, and protective layer which finally becomes thermal insulation and explosion-proof film with metal sputtering method. Optical micro-attach technology is used in the polyester film which is the base of 3M crystalline auto film. It is coated with more than 240 layers of optical coatings in order to achieve better thermal insulation performance, and be the top anti-explosion and heat-insulating film with clear sight. I hope my answer can help you. Thank you.
Q:Is the ball mill used in production of refractories?
It will be used. It is used in the process of milling the raw material which is less demanding on technology and in relatively large amount. Is there lots of network marketing for refractory industry? Is the competition fierce on the Internet?
