What distinction do phosphatic wear-resisting brick and tall aluminous brick have?

Phosphatic wear-resisting brick and tall aluminous brick are common fireproof material, but their composition, function and applied setting differ somewhat. It is the main distinction between them below:


1.Brick of composition phosphate wear-resisting:  Basically mix by phosphatic binder wear-resisting aggregate (wait like corundum, bauxite) make. Phosphate offerred good strength and wearability as binder.
Tall aluminous brick:  Basically make by bauxite and other aluminous qualitative raw material, the oxide that contain aluminium (Al₂O₃ ) be in normally 48% above, have taller fireproof spend and intensity.
2.Brick of wear-resisting of fireproof function phosphate:  Fireproof degree normally taller, but opposite for, fireproof temperature slightly under tall aluminous brick. Its are main the advantage depends on wearability.


Tall aluminous brick:  Fireproof degree tall, can achieve above of 1600 ° C normally, have very good high temperature stability and wear.
3.Brick of wearability phosphate wear-resisting:  As a result of its special class status, phosphatic wear-resisting brick has superior wear-resisting performance, suit to be in mechanical wear is used in more serious environment.
Tall aluminous brick:  Although tall aluminous brick has certain wearability, but its wear-resisting function normally not as good as phosphatic wear-resisting brick, basically suit to bear high temperature and chemistry are eroded.
4.Brick of wear-resisting of applicable setting phosphate:  Main application is built at casting, the lining of the industry such as steely smelt and wear-resisting component, suit to bear tall wear away, the environment of high temperature.
Tall aluminous brick:  Apply extensively at furnace of cement kiln, electric arc, fusion furnace to wait for the liner of kiln of high temperature furnace, suit to bear high temperature and chemistry are eroded.
5.Cost and brick of construction phosphate wear-resisting:  Production cost is normally higher, the need when construction notices its applicable temperature and humidity condition.
Tall aluminous brick:  Make and construction is relatively simple, apply extensively at equipment of of all kinds high temperature, cost normally relatively economy.
Brick of summary phosphate wear-resisting and tall aluminous brick have its distinctive function and applied field each. When the choice, should ask to have integrated consideration with the element such as economy according to specific working requirement, fireproof function, choose right fireproof stuff in order to ensure.
