What is the difference between clay bricks and three-level high alumina bricks?

Phapang e kholo lipakeng tsa litene tsa letsopa le litene tse phahameng tsa alumina ke likarolo tsa aluminium le bongata ba bongata.

Litene tse nang le 40-48% ea aluminium ke litene tsa letsopa. Litene tsa letsopa li na le matšoao a fapaneng a N-1, N-2, N-3, le N-4 maemong a naha. Ha ho etsoa le ho sebelisoa, litene tsa letsopa tsa N-2, N- 3 li sebelisoa haholo, hape ke lihlahisoa tse tloaelehileng tse hlahisoang ke baetsi ba bangata. Boima ba molumo bo lipakeng tsa 2.1-2.15. Tabeng ea litene tsa letsopa tsa N-1, litsupa tse ling li phahame ho feta litene tsa alumina tsa sehlopha sa boraro.

Bricks with 55% aluminum content are third-grade high-alumina bricks with a bulk density between 2.15-2.25. At present, due to the production area and raw materials, the aluminum content of clay bricks is about 56%. The aluminum content of the clay bricks in Xinmi, Henan is about 56%, and the body density is above 2.15, which is basically a third-grade high-alumina brick. Moreover, the firing temperature is high, and the chemical index is not lower than the third-grade high alumina brick, but there is a difference in the softening temperature of the load.

The aluminum content of the three-level high alumina bricks currently produced is about 63%, and some have 65%. The body density is above 2.25, and the load softening temperature is slightly lower. In terms of chemical indicators, it is only different from the second grade high alumina bricks in unit weight and load softening temperature.

Ponahalo ea ‘mala oa litene tsa letsopa le litene tse phahameng tsa alumina tsa sehlopha sa boraro li ntse li fapane. Litene tsa letsopa li mosehla o mofubelu, ‘me litene tsa grade-alumina tsa grade ea boraro li tšoeu ebile li mosehla.

Ho na le phapang ea boima lipakeng tsa litene tsa letsopa le sehlopheng sa boraro sa litene tse phahameng tsa alumina. Mefuta e tšoanang ea litene tsa letsopa e bobebe ho feta litene tsa grade alumina tse phahameng. Mocheso oa ho thunya le ona o tlase ka 20-30 ° C.

Litene tsa letsopa le sehlopha sa boraro sa litene tse phahameng tsa alumina li na le phapang pakeng tsa matla le khatello ea mojaro oa khatello. Matla a tlamang a litene tsa letsopa ke 40Mpa, ha matla a ho hatella a sehlopha sa boraro se phahameng sa litene tsa alumina ke 50Mpa. Mojaro o bonolo oa litene tsa letsopa le oona o phahame ho feta oa sehlopha sa boraro. Refractoriness ea setene sa aluminium e 30-40 ℃, ‘me ho ts’oaroa ha eona ho ka ba 30 ℃ ka tlase.
