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

Ọdịiche dị n’etiti brik ụrọ na brik alumina dị elu bụ ọdịnaya aluminom na njupụta buru ibu.

Brik nwere ọdịnaya aluminom 40-48% bụ brik ụrọ. Brik ụrọ nwere ihe ngosi dị iche iche nke N-1, N-2, N-3, na N-4 na ọkọlọtọ mba.

N’ihe banyere brik ụrọ N-1, ụfọdụ ihe ngosi dị elu karịa brik alumina dị elu nke atọ.

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.
