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

Umehluko omkhulu phakathi kwezitini zobumba nezitini ezine-alumina ephezulu okuqukethwe yi-aluminium kanye nobuningi besibalo.

Izitini ezinokuqukethwe kwe-aluminium okungama-40-48% yizitini zobumba. Izitini zobumba zinezinkomba ezihlukile ze-N-1, N-2, N-3, ne-N-4 ezingeni likazwelonke. Ekukhiqizweni nasekusebenziseni, izitini zobumba ze-N-2, N- 3 zisetshenziswa kabanzi, futhi ziyimikhiqizo ejwayelekile ekhiqizwa ngabakhiqizi abaningi. Ubuningi bevolumu buphakathi kuka-2.1-2.15. Endabeni yezitini zobumba ze-N-1, ezinye izinkomba ziphakeme kunezitini eziphakeme zebanga lesithathu ze-alumina.

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.

Umbala wokubukeka kwezitini zobumba nezitini eziphakeme ze-alumina zebanga lesithathu usahlukile. Izitini zobumba zibomvu ngokuphuzi, kuthi izitini eziphakeme ze-alumina zebanga lesithathu zimhlophe futhi ziphuzi.

Kunomehluko wesisindo phakathi kwezitini zobumba nezitini zebanga lesithathu eziphakeme ze-alumina. Izitini zobumba ezifanayo zona zilula kunezitini eziphakeme zebanga lesithathu ze-alumina. Izinga lokushisa lokudubula nalo liphansi ngo-20-30 ° C.

Izitini zobumba kanye nebanga lesithathu lezitini eziphakeme ze-alumina zinomehluko emandleni acindezelayo nasekulayisheni izinga lokushisa lokuthambisa. Amandla acindezelayo wezitini zobumba angama-40Mpa, kanti amandla acindezelayo ebanga lesithathu izitini eziphakeme ze-alumina angama-50Mpa. Umthwalo othambile wezitini zobumba nawo uphakeme kunowebanga lesithathu. Ukuphinda kukhanye kwesitina se-aluminium kungama-30-40 ℃, futhi ukuphindaphinda kwaso kucishe kube ngu-30 ℃ ngaphansi.
