Round Kiln Calcined Bauxite 85% 3-5mm of CNBM in China

1.Structure of Calcined Bauxite 85% Content Description

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. 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 85% Content

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 85% Content

Raw bauxite is typically classified according to its intended commercial application,such as abrasive ,cement ,chemical, metallurgical, and refractory .as raw material for use in high alumina and super duty refractory bricks and shapes ,plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.

6.FAQ of Calcined Bauxite

1). Q: Are you a factory or trading company?

A: We are a factory.

2). Q: Where is your factory located? How can I visit there?

A: Our factory is located in ShanXi, HeNan, China. You are warmly welcomed to visit us!

3). Q: How can I get some samples?

A: Please connect me for samples

4). Q: Can the price be cheaper?

A: Of course, you will be offered a good discount for big amount.

Q: How many kinds of A-level fireproof and thermal insulation materials are there?: Please give us some information about the kinds of A-level fireproof and thermal insulation materials in the market.

Q: Which refractory quality inspection authority is good?: National testing agencies include National Refractory Inspection Center (i.e. LIRR), China Building Materials Academy (Guanzhuang, Beijing), National Center for Ceramic and Refractory Materials Inspection (Shandong) and China Metallurgical Research Institute (Beijing).

Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: The refractory that you want is high temperature furnace which you can buy from the market.

Q: What are the filling refractories in door leaf of class A fire resistant door?: Magnesium chloride, magnesium oxide, perlite and other mixtures.

Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?: “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.

Q: What are the classifications of refractory? Which category does steel ladle castable belong to?: In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.
