Alumina bricks are created so that they are highly stable and proof against high temperatures and from erosion from chemicals. One of the main uses of those bricks is making linings for blast furnaces, air furnaces, heat furnaces, and reverberatory furnaces. There are various manufacturers in China and those bricks can be obtained on Alibaba.
Four Grades Of Alumina Bricks
- Grade 1 contains 75% from the primary component.
- Grey 2 contains at the very least 60% approximately 75% of the primary component.
- Grade 3 has between 48% and 60% of the primary component within the brick.
- Grade 4 can be a special grade which has over 80% in the primary component in the alumina bricks.
Using High Alumina Bricks
These bricks are created specifically when it comes to lining hot machinery including some kinds of furnaces and kilns. These bricks are employed within the Iron and Steel Industries. One can use them with the military but for the manufacturing of cement, glass, petrochemicals, and ceramics.
How Are Alumina Bricks Made?
Rsrefractoryfirebrick.com/high-alumina-bricks are made much likewise as making clay bricks. The main difference may be the specific ingredients accustomed to create these bricks. The process of making these alumina bricks requires the application of higher temperatures than is commonly used for clay bricks. Chinese production practices be determined by the objective of the bricks.
Rongsheng Refractory
This is among one of China's leading suppliers of high alumina bricks. They have four factors that are positioned in China plus they have one company they utilize for international trade. They are making refractory products for in close proximity to twenty years and are capable of supplying up to 6000 tons monthly for customers.
When purchasing be sure to specify that you might want its packaging to be highly resistant against vibrations to stop damage. If there are time constraints make sure you see that they could deliver promptly.

Manufacturing Process Of Magnesia Carbon Bricks
Magnesia carbon bricks are made of magnesium oxide (melting point 2800 ℃) and carbon material with a high melting point that is difficult to be infiltrated by slags by adding a variety of non-oxide additives. http://rsrefractoryfirebrick.com/magnesia-carbon-bricks/ are mainly used in the converter, AC arc furnace, DC arc furnace lining, ladle slag lines and other parts.
The factors for the production of magnesia carbon brick incldue raw materials, binding agents and additives.
1) Magnesia sand
Magnesia sand should have high purity. Compared to sintered magnesia brick, fused magnesia brick has more complete crystal structure and stable reducing effect on carbon, so the production of magnesai brick turns to fused magnesia bricks. Given the binding state of carbon and infiltration of binding agents, fused magnesia can be mixed with sintered magnesia.
Magnesia carbon brick made of magnesia sand with high MgO content, large periclase particles and a lime-silica ratio of greater than 2 has the best quality.
2) Graphite
Graphite is another raw material for magnesia carbon bricks. it has good basic refractory properties. It contains 85%-98% fixed carbon and 13%-2% ash nd has a relative density of 2.09-2.23 and a melting point of 3640K ( volatile).
There are three reasons for the oxidization of graphite during use:
a. Oxygen in the air
b. Oxides in the slag
c. Oxides in graphite itself
Oxide impurities can react with graphite and make the structure loose, permeability increased and strength reduced, which is the main reason for the damage of magnesia carbon brick. Therefore, graphite with high purity and large flake crystals is mainly used for the production of magnesia carbon brick.
3) Binding agent
Binding agent is important for magnesia carbon brick and other carbon http://rsrefractoryfirebrick.com/. Graphite and refractory oxides are not miscible. Thwy rely on binding agents to bond. At high temperature, the binding agent will be carbonized and form carbon bond with graphite. These binding agents are typically phenolic resins, modified bitumen, petroleum cracking by-products. Among them, phenolic resin has the best performance.
4) Additives
During the damaging process of magnesia carbon bricks, the oxidization of graphite is the main reason. The oxidation and carbon loss result in loose structure and weak strenth. In order to improve the oxidation resistance of magnesia carbon bricks, a certain amount of additives are added, including silica powder, alumina powder, FeSi alloy, CaSi alloy, SiC, Si3N4 and B4C. another function of additives is to build a bridge between refractory oxides and graphite and reinforce the binding between refractory oxides and graphite.

Why Choose High Alumina Bricks?
If you want to build a something like a factory building with the best materials, high alumina bricks could be the best option for you. Rsrefractoryfirebrick.com/high-alumina-bricks are made from chemical substances such as aluminium hydroxide, bauxite, and clays.
By definition high alumina bricks are formulated so that they can be fireproof. Nowadays, most companies prefer high alumina bricks when they are going to construct something because it is known as the strongest of refractory materials.
Why are these high alumina bricks so special and what are the advantages of using these bricks?
As it is mentioned, these bricks contain high alumina. Alumina for refractories is derived from natural and artificial deposit. Natural sources are consisting of bauxite and diaspora. While artificial sources are consisting of Calcined Alumina, Sintered Alumina, and Fused Alumina. Bauxite is the ore containing boehmite (Al2O3.H2O) or Gibbsite (Al2O3.3H2O) in varying proportions. Bauxite also contains iron oxide, aluminosilicates, and titania.
Bauxite is rich in iron oxides and other impurities that can be used to make Calcined alumina through the Bayer process or to make aluminum metal. Bauxite used directly to create refractory should have low impurity content. Immediately after calcined bauxite mined, later it will be burned in the rotary for stabilization. The main component is corundum (alumina α) with a little mullite and a small amount of glass phase. The other component of refractory bricks is Clay. Also you might never know about benefits of insulation bricks, so you should know about it.
Clay from different groups of material is formed by the metamorphosis rocks weathering process. This material is generally very smooth with a particle size less than 2 microns. The best bricks are rsrefractoryfirebrick.com that contain high alumina-silicate. This refractory group usually has good resistance to acid slag.
Generally, this material offers some features such as:
Good for an insulator material.
Some of the types have a complex expansion behavior, but most of them only have a small thermal expansion.
Medium strength at a high temperature contains the glass phase at a low melting point.
Good resistance to acid slag.
Good resistance to thermal shock.
Inexpensive and always available.
What are the benefits of high alumina bricks?
Since these bricks are formulated in particular by using high alumina, so these bricks can resist any flame or heat. You can use the bricks to build furnaces, kilns iron, a place to cook, house building, and much more. Talking about the quality, you must not doubt what we have provided to you. At a first glance, these bricks are just similar to clay bricks that are used for building. However, when you identify its contents, these bricks are made of refractory materials.
In summary, High Alumina Bricks can be the best material that you can use to build anything. You will get so many advantages from these high alumina brick anyway. The chemical contents formulated make the bricks so resistant, especially resistant to fire.
