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.

- Q:Does anyone know the difference between refractory and thermal insulation material?
- I will give you a relatively simple analysis. Refractory can bear above 1,200 degrees centigrade, but some refractory is not insulated. For example, refractory brick can be directly in contact with heat source, but it has little insulation effect. Refractory includes ceramic fiber, high silica and so on. And they can be also insulated. But insulation effect is not so good as insulation material. Insulation material generally can bear below 800 degrees centigrade, and it is large in thermal resistance, low in heat conductivity coefficient and high in porosity factor, thus reducing heat loss. Briefly speaking, insulated material is to store most heat, and just let a small quantity of heat run of through air, thus insulating heat. Refractory includes glass fiber, rock wool, aerogel blanket and so on.
- Q:Fefractory of aluminium oxide.
- It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.
- Q:What are the refractory materials above 1000℃
- corundum would be fine
- Q:What is the the best matching ratio of refractory cement?
- The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement. I hope my answer will be helpful to you.
- Q:what is steel fire door made of ?
- 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.
- Q:What is the common inorganic fireproof and thermal inuslation matertial?
- Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
- Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- 3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.
- Q:What is the material of fire resistant glass reinforced plastics grating?
- What is the material of fire resistant glass reinforced plastics grating?
- Q:What are the advantages of refractory material?
- Jingute WHL type, GDS type
- Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Many manufacturers are facing the same problem, difficult to find the order, order the payment contract is more difficult, it is difficult to have binding, the better solution is to seek third party secured transactions, see the whole production or see full delivery
