ʻO ke kiʻekiʻe alumina castable kahi ʻano refractory castable e hoʻohana ana i nā mea alumina kiʻekiʻe e like me nā aggregates a me ka pauka a laila hoʻohui ʻia me ka mea paʻa. ʻO ke kiʻekiʻe alumini refractory castable he kiʻekiʻe mechanical ikaika, maikaʻi thermal shock kū'ē, maikaʻi corrosion kū'ē. kiʻekiʻe alumina refractory castable mea he amorphous refractory me kiʻekiʻe mobility, refractory kiʻekiʻe alumina castable hana mai refractory aggregate, pauka, binder, additives, wai, a me nā mea wai. Hiki ke hoʻohana ʻia nā mea hoʻoheheʻe alumina kiʻekiʻe me ke ʻano o ka hoʻoheheʻe ʻana i ka pūnaewele, ka haʻalulu a i ʻole ka hoʻopili ʻana, hiki ke hana i kahi preform i hoʻohana ʻia a hiki ke hoʻohana ʻia me ke ʻano hana hoʻoheheʻe akā paʻakikī ʻole me ka wela.
E koho i nā mea maka o nā mea hoʻolei alumini kiʻekiʻe e like me ke ʻano.
E helu i ka helu ʻana a me ke ʻano o ka aggregate, pauka, binder a me nā mea hoʻohui e like me ke ʻano kumu kumu, a mālama pono i nā ʻāpana pauka aggregate.
E hoʻokomo i ka paona paona a me ka pauka i loko o ka blender kekahi ma hope o kekahi, a laila ninini i ka pauka i loko o ka hui a hoʻoulu no 8-10 mau minuke.
E hoʻokomo i ka mea ninini alumini kiʻekiʻe i hoʻoulu ʻia i loko o ka ʻeke ton, i hoʻolako ʻia me nā mea hoʻohui a me ka binder, a laila pūʻulu.
E mālama ʻia nā mea ninini alumini kiʻekiʻe i hoʻopaʻa ʻia i loko o ka hale kūʻai, a e hōʻailona ʻia ka lā a me ka moisture-proof a me ka wai.

Hoʻokumu ʻia ka alumina castable kiʻekiʻe ma hope o ka hana ʻia ʻana ma lalo o ka wela kiʻekiʻe i ka rotary a wili i ka pauka. ʻO ka huahana no ka hana ʻana i nā castables refractory kiʻekiʻe, he mea hoʻohana i hoʻohana ʻia i nā keʻena wela kiʻekiʻe i nā ʻoihana e like me ka metallurgy, nā mea kūkulu hale, nā kemika, nā mea kanu uila. Hiki ke hoʻohana ʻia nā pahu alumina kiʻekiʻe ma nā wahi aʻe.
