Ka wehewehe ʻana o ka Alumina Castable kiʻekiʻe
ʻO ka alumina castable kiʻekiʻe kahi ʻano castable refractory e hoʻohana ana i ka mea maka alumina kiʻekiʻe e like me nā aggregates a me ka pauka a laila hoʻohui ʻia me ka mea hoʻopaʻa. Loaʻa i ka castable refractory alumini kiʻekiʻe ka ikaika mechanical kiʻekiʻe, ke kūpaʻa haʻalulu thermal maikaʻi, ke kūpaʻa corrosion maikaʻi. ʻO ka castable refractory alumina kiʻekiʻe kahi refractory amorphous me ka neʻe kiʻekiʻe, hana ʻia ka castable alumina kiʻekiʻe refractory mai ka aggregate refractory, ka pauka, ka mea hoʻopaʻa, nā mea hoʻohui, ka wai, a i ʻole nā mea wai ʻē aʻe. hiki ke hoʻohana ʻia nā castables alumina kiʻekiʻe me ke ʻano hoʻoheheʻe o ka hoʻolei ʻana i ka pūnaewele, ka haʻalulu a i ʻole ka tamping, hiki ke hana ʻia kahi preform i ka hoʻohana ʻana a hiki ke hoʻohana ʻia me ke ʻano hana hoʻolei akā e hoʻopaʻakikī me ka ʻole o ka hoʻomehana ʻana.
Nā Waiwai o ka Alumina Castable Kiʻekiʻe
- Ka ikaika kiʻekiʻe,
- Paʻa ka leo,
- Hoʻomehana maikaʻi,
- Ke kū'ē'ē'ana i ka waikawa,
- Ke ahonui i ka mahana kiʻekiʻe,
- Kū'ē maika'i i ka ha'alulu wela,
- ʻO ke kūpaʻa slag maikaʻi,
- Ke kūpaʻa maikaʻi o ka ʻaʻahu,
- Kū'ē maika'i i ka palaho,
- He kūpono ke kūkulu ʻana.
Kaʻina hana hana ʻelima-ʻanuʻu o ka High Alumina Castable
E koho i nā mea maka o nā mea hoʻolei alumini kiʻekiʻe e like me ke ʻano.
E helu i ka gradation a me ka nui o ka aggregate, ka pauka, ka mea hoʻopaʻa a me ka mea hoʻohui e like me ke ʻano o ka mea maka, a kāohi pono i nā ʻāpana pauka aggregate.
E hoʻokomo i ka ʻōpala kaupaona a me ka pauka i loko o ka mea wili kekahi ma hope o kekahi, a laila e ninini i ka pauka i loko o ka ʻōpala a hoʻowali no 8-10 mau minuke.
E hoʻokomo i ka mea ninini alumini kiʻekiʻe i hoʻoulu ʻia i loko o ka ʻeke tona, i hoʻolako ʻia me nā mea hoʻohui a me ka mea hoʻopaʻa, a laila e hoʻopili.
Pono e mālama ʻia nā mea ninini alumini kiʻekiʻe i hoʻopaʻa ʻia i loko o ka hale kūʻai, a e hōʻailona ʻia ka lā a pale i ka makū a me ka wai ʻole.
Nā Pōmaikaʻi o ka Alumina Castable Kiʻekiʻe
- ʻO ke kūpaʻa kiʻekiʻe, ʻO ke kūpaʻa kiʻekiʻe ma lalo o ke kaumaha,
- Kiʻekiʻe ka nui, haʻahaʻa ka porosity,
- ʻO ke kūpaʻa slag maikaʻi a me ke kūpaʻa i ka pala,
- Ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu,
- Ke kūpaʻa maikaʻi nei i ka hana flake,
- Paʻa maikaʻi o ka haʻalulu wela,
- Ke kūpaʻa ʻana i ka holoi ʻana,
- Ikaika wela maikaʻi.

Ka Hoʻohana ʻana o ka Alumina Castable Kiʻekiʻe
Hana ʻia ka alumina castable kiʻekiʻe ma hope o ka hana ʻia ʻana ma lalo o ke ana wela kiʻekiʻe i ka rotary a wili i ka pauka. ʻO ka huahana no ka hana ʻana i nā castables refractory kiʻekiʻe, he mea hana pono ʻole ia i hoʻohana ʻia i nā hale hana wela kiʻekiʻe i nā ʻoihana e like me ka metallurgy, nā mea kūkulu hale, nā kemika, nā mea hana uila. Hiki ke hoʻohana ʻia nā castables alumina kiʻekiʻe ma nā wahi aʻe.
- Ka uhi ʻana o ka umu wili,
- Ka uhi hoʻololi wela,
- ʻOihana hana hao,
- ʻOihana kemika,
- ʻOihana kūkulu hale.
