There are many types of high alumina bricks, including special grade, first grade high alumina brick, second grade high alumina brick, and third grade high alumina brick. Of course, the price of special high-alumina bricks is the best, and the aluminum content is the most. Today, I will introduce the production process of the next special high-alumina bricks: the production process of high-alumina bricks and multi-clinker clay bricks are similar, but the difference lies in the clinker in the ingredients. The proportion is relatively high, which can be as high as 90-95%. The clinker needs to be sorted and sieved to remove iron before crushing. The firing temperature is relatively high. For example, when high alumina bricks such as I and II are fired in a tunnel kiln, they are generally 1500 ~ 1600 diguli .
Enkola y’okufulumya mu China ekakasizza nti nga tebannaba kubetenta, clinker ya high-aluminum esunsulwamu nnyo era esengekeddwa, era eterekeddwa mu mitendera. okukozesa bauxite clinker ne combined clay fine grinding method kiyinza okulongoosa omutindo gw’ebintu.
Eby’obugagga n’enkozesa amatoffaali ga alumina aga waggulu galina obutonde obw’amaanyi, okuziyiza okw’amaanyi eri okukulugguka kwa asidi ne alkaline slag, n’amaanyi g’ebyuma eby’ebbugumu eringi, kale gakozesebwa nnyo mu makolero g’ebyuma n’ebikoomi ebirala.
Densite y’amatoffaali ga alumina aga waggulu esalibwawo okusinziira ku bbeeyi. Densite ey’awamu eri wakati wa 2.3-2.5g/cm3. gy’ekoma okuba ey’ebbeeyi ennyo, ebbeeyi gy’ekoma okuba ey’ebbeeyi. amatoffaali ga alumina aga waggulu agasooka okutwalira awamu geetaaga okusukka 2. 4 mu makolero, era nga gamala.
High alumina bricks are divided into four grades according to the aluminum content. The aluminum content of the third-level high-alumina bricks is not less than 55 percent, the second-level high-alumina bricks are not less than 65, and the first-level high-alumina bricks are not low. At 75, the aluminum content of super high alumina brick is above 85. As for the shape of high alumina Amabaati, ng’oggyeeko amatoffaali ga alumina aga waggulu aga mutindo, waliwo n’amabaati aga general high alumina, era agayitibwa amatoffaali ga alumina aga waggulu aga high alumina ag’enjawulo. singa ekifaananyi kiba kya bulijjo nnyo, kitera okuyitibwa amabaati ag’enjawulo aga alumina aga waggulu. mu bufunze, okusinziira ku nkozesa entongole ey’ekikoomi okujja okukola okulagira{15}}
