Q:What is the density of a super high alumina brick and what is the price?

Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan

Q:What is spalling resistant high alumina brick?

Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.

Q:The cloth blowing is not uniform on the lime kiln refractory brick is damaged it

People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.

Q:Use of high alumina refractory bricks?

High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..

Q:How to make refractory bricks and boiler wall adhesion more firm?

Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry

Q:What are the requirements for Rubble backfill height?

1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

Q:What refractory material does cupola lining use?

It's made of high quality refractory material: 1770 ~ 2000 centigrade.

Q:Which thermal shock stability of clay brick and high alumina brick is good?

Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products

Q:Does the chimney have high acid resistance?

If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.

Q:What are the main components of high alumina bricks?

High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
