1.Refractory Grade:

Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.  

3. Rotary calcined bauxite:

 Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.

4. Shaft kiln calcined bauxite:

Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom. 


1.Aluminium metallurgy.

2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.

3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.

 It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)

4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace.     After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.

5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

6.Producing bauxite cement.


8.Ceramics industry.

9.Chemistry industry for all kinds of aluminium compound.

Q:What materials is silicious thermal insulation board made of?
Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.
Q:How to choose refractory material
Refractory fiber in different furnace material requirements are different, I would like to know is methanol as a protective gas, fire fiber, cotton material what?.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:What is refractory brick?
Capability1. Refractory brick is also known as firebrick. It is faint yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
Q:how does the fire endurance of first rate fire resistant window?
the classes are different. class A window not less than 1.5 hours, and the time is short, class B window not less than 1 hours, with shorter time, Class C window not less than 0.5 hours.
Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:What antioxidant will be used in refractories?
Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I can help you.
Q:What is the classification standard of fireproofing material levels?
the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. class B1: combustible building materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
Q:What kind of refractory materials are used in metallurgy industry?
Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
Level A of non-combustible insulation materials are: W W inorganic active wall insulation materials, cement foam insulation board, glass beads of insulation mortar, rock wool board, glass wool board and foam ceramics, ect. Th e level A is non-combustible material, characterized with low density, low thermal conductivity, high bearing capacity, convenient construction, economy and durablity, and widely used as the thermal insulation materials in hot pipes, thermal equipment and other pipe-line equipment and industrial architectures, and as the thermal insulation, heat insulation and sound-absorbing materials in industrial and civil building envelope. Because of its good thermal stability, it is more used as fire-resistant protective coating material of steel structure.
