Product Description:

refractory grade size 1-3mm calcined bauxite

 

 

1.  Calcined Bauxite 1-3mm brief  introduction:

 

   Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated 

aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).

Q:What are the characteristics of thealuminium oxide refractory?
Alumina refractory are characterized by uniform granularity, mobility, good dispersity. And it has good acid and alkaline slag erosion resistance, high strength, abrasion resistance, high melting point, erosion resistance , anti-flush and excellent thermal shock resistance.
Q:Which fire-resistant materials have good viscidity?
The viscidity of fire-resistant materials is also known as the binding performance of fire-resistant materials. It can be divided into chamotte and chemical binder. Both can work at normal or high temperature. The most commonly used chamotte are soft clay and aluminate cement. The commonly used chemical binders include sodium silicate, phosphoric acid, aluminum sulphate, aluminium phosphate, phenolic resin, etc. Fire resistant material is a complicated and overloaded system and we cannot know its materials and chemical components from the name alone. Both gunning mix and repair mix contain binder components. If they can used after adding water, then they may contain clay or fire resistan aluminum silicate cement.
Q:Why the corundum can be used as refractory
It can resiatant to friction wear.The alumina material is a kind of neutral material with high temperature resistance, anti-acid, anti-corrosion, alkali resistance, and high hardness of corundum. The disadvantage is the poor thermal shock resistance, the main chemical composition of corundum is aluminium oxide and the melting point of corundum is 2080 degrees
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:What kind of materials are needed to make refractory bricks?
Who knows what kind of materials are needed to make refractory bricks?
Q:How can refractory materials be divided?
There are many criteria for the classification of refractories.Just referring to a book about refractory.
Q:What are the characteristics of clay refractory materials?
Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
Q:What are the materials for refractory materials? What are their name?
High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
Q:How many refractories are there for boiler above 1200 ℃?
Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
Q:How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
