FAQ

What is the standard size of high alumina brick?

The country has laid down a number of criteria for the use of refractory bricks to unify market demand.

What's the price of high alumina refractory bricks?

The price of high alumina refractory bricks varies greatly according to the content of AL2O3.

The difference between light high alumina brick and heavy aluminum brick

Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is fired at 1300 - 1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.

Aluminum content 38, silicon content 55 What refractory bricks?

Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite

How to reduce the harm caused by two times mullite in high alumina refractory material

Prolong the sintering time and adjust the aluminum content of the high alumina brick.

Use of high alumina refractory bricks?

Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.

How many cubic bricks does a high alumina brick have?

It is related to the content of aluminum in high alumina bricks.

What materials are used for roof insulation?

The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
