Production description
High alumina refractory brick contain Al2O3 more than 60%, which is made of high grade bauxite through high temperature calcinations.
Its refractories is usually above 1750 °C.The main mineral components are corundum and mullite phases.It is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.
According to Al2O3 content,it can be divided into three degrees:The Al2O3 content is more than 75%.The Al2O3 content range from 60% to 75%.The Al2O3 content range from 48% to 60%.
1.High-temperature endurable .
2.Good thermal shock resistance.
3.High cold crushing strength
4.Good resistance to abrasion and corrosion.
5.Good thermal spalling resistance.
6.High mechanical strength.
7.Good volume stability at high temperature.
How many types are there in our refractory bricks
According to the using eqiment:The high alumina is divided into different kinds according to the content alumina and usage,they are widely used in glass furnace, blast furnace,hot blaststoves electric arc furnace,cement kiln and other heat-engineering equipments.
According to its property and function :Common high alumina bricks,phosphate-bonded high alumina bricks for cement kiln,spalling resistance high alumina bricks.
Physical and chemical indexes
These bricks are made mainly from (fire) clays and bauxites.
For an alumina content ranging from 20 to 50%, there are three sub categories:Medium-duty Fireclay bricks, High-duty Fireclay bricks and Super-duty Fireclay bricks.
They can develop good volume stability at high temperatures, high mechanical strength, spalling, abrasion and corrosion resistance.They can be mixed with additives such as andalusite, cordierite or mullite, to withstand thermal shocks.
They are used for the lining of high temperatures industrial facilities and equipment such as kilns, furnaces and combustion chambers.They can withstand high temperatures, important thermal shocks, but also mechanical and chemical constraints such as abrasion, chemical corrosion and physical wear resistance.

Q6.What is the service life of your bricks?
A:The service life of different bricks is unlike.It also depends on your using condition and method.
High alumina brick is one of the indispensable basic refractory materials in the upper and middle parts of blast furnace body in iron and steel industry
Common low-creep high-alumina bricks can be used in blast furnace hot blast stoves, as well as other industrial kilns, and can also be made into low-creep high-alumina bricks of different sizes according to specific construction requirements, such as lattice bricks, special-shaped bricks, anchor bricks, etc. , mainly used in industrial kilns in long-term high temperature environments
high alumina refractory bricks is mainly used around the furnace cover, electrode holes and exhaust holes of electric furnaces, and its service life is 1 to 2 times longer than that of silica bricks.
Insulating high alumina refractory bricks mainly refer to refractory products with an aluminum content of more than 48%. They are also called lightweight high-alumina bricks or heat-insulating high-alumina bricks due to their advantages of low bulk density, light weight, and good heat insulation effect. . It is a kind of thermal insulation refractory brick commonly used in high temperature industrial kilns and thermal equipment.
Magnesia alumina bricks use periclase as the main crystal phase and magnesia-alumina spinel as the matrix. They are better in thermal shock resistance than magnesia bricks. In order to improve the thermal shock resistance of magnesia bricks, alumina or alumina is introduced into the ingredients. Bauxite clinker fine powder to form a magnesia-alumina sharp stone matrix, thereby making magnesia-alumina bricks
Magnesia chrome bricks are refractory products with magnesia (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. The main raw materials for the manufacture of magnesia-chrome bricks are sintered magnesia and chromite.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
