Calcined Bauxite

Product Description

Bauxite is the main raw material for making high grade refractory, refractory brick,

castable, special ceramics, casting coating, alumina cement, industrial alumina, and

other amorphous refractory.

Mainly used in refractory, industrial aluminium metallurgy, precision casting, water

treatment, special ceramics and coating industry.

Grit size: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-15mm, 0-5mm, 0-50mm, 100mesh,

200mesh, 325mesh, etc. Other sizes available upon customers request.

Physical and Chemical Indicators

Q: What do RH and DH stand for in refractories?: DH :For human intelligence (diameter, board of directors). )

Q: What is the upper temperature limit for refractory materials?: Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.

Q: How to divide fire rating of decorating materials ?: Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.

Q: The effect of a high content of water in liquid resin exerted on refractory material?: For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.

Q: What are included in roof thermal insulation fireproofing material?: Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.

Q: How long is the fire-resistant time of fireproof wooden door?: National standards define the fireproof door as class A, class B, class C, among which fire-resistant time of class A fireproof door should not be less than 1.5 hours, class B should not be less than 1 hour and Class C should not be less than 0.5 hours.

Q: What kind of material is refractory bauxite?: Bauxite (aluminous soil; bauxite), also known as alumina or bauxite ore whose main component is alumina oxde, is a hydrated alumina containing impurities. It is an earthy mineral. It is white or gray, and as it contains iron, it is also brownish yellow or light red. Density of 2.4-2.5g / cm3, hardness 1-3, opaque and crispy. It is extremely difficult to melt.

Q: What are the requirements for the performance of refractory materials?: Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.

Q: What are the new types of refractories? What are the characteristics? Their applications and developments?: A new type of refractory materials are: A12O3-TiO2-SiO2 refractories, MgO-A12O3-TiO2 refractories, MgO-CaO-TiO2 refractories, MgO-SiC-C refractories, nanotechnology MgO-C brick, MgO-AL2O3-AIN refractories, MgO-La2O3 refractories etc..
