Nā Piliki AZS
Piliki i hoʻohuihui ʻia ʻo AZS, i ʻike ʻia hoʻi ʻo ka piliki corundum zirconium i hoʻopili ʻia, he mea refractory hana kiʻekiʻe. ʻO ka piliki i hoʻopili ʻia ʻo AZS i hana nui ʻia me ka pauka alumina maʻemaʻe, zirconium oxide (ZrO2 ma kahi o 65%) a me ka silicon dioxide (SiO2 ma kahi o 34%) a me nā mea maka ʻē aʻe. Ma hope o ka hoʻoheheʻe ʻia ʻana i ka mahana kiʻekiʻe i loko o ka umu uila, ua hoʻokomo ʻia i loko o ka ʻōmole a hoʻomaʻalili ʻia.
Kaʻina hana hana:Hoʻohui ʻia ke one zircon i koho ʻia a me ka pauka alumina ʻoihana ma kahi ʻāpana kikoʻī (maʻamau 1:1), a hoʻohui ʻia kahi liʻiliʻi o Na2O (i hoʻohui ʻia ma ke ʻano o ka sodium carbonate) a me B2O3 (i hoʻohui ʻia ma ke ʻano o ka boric acid a i ʻole borax) ma ke ʻano he flux. Ma hope o ka hui like ʻana, hoʻoheheʻe ʻia i ka mahana kiʻekiʻe (e like me 1800 ~ 2200 ℃) a hoʻolei ʻia i ke ʻano. Ma hope o ka hoʻomaʻalili ʻana, ʻoki ʻia a hana ʻia e hana i nā piliki AZS i hoʻohui ʻia me nā ʻano a me nā nui kikoʻī.
Nā Hiʻohiʻona Huahana Koʻikoʻi:
1. Ke kūpaʻa wela kiʻekiʻe loa:I hana ʻia e ka electrofusion ma 1800 ~ 2200 ℃, ʻoi aku ka kiʻekiʻe o kona refractoriness ma mua o nā piliki refractory maʻamau a me kahi mahana palupalu kiʻekiʻe. Hiki iā ia ke hana paʻa no ka manawa lōʻihi ma lalo o nā kūlana hana hoʻoheheʻe wela kiʻekiʻe me ka ʻole o ka deformation creep maopopo.
2. Kū'ē maika'i loa i ka palaho:He kūpaʻa ikaika kona i ka ʻino a me ka pala i ke aniani hoʻoheheʻe ʻia, ka ʻōpala waikawa, ke kinoea flue wela kiʻekiʻe, a me nā mea ʻē aʻe. Hiki iā ia ke pale pono i ka pala kemika a me ke komo kino o nā mea i hoʻoheheʻe ʻia, e hoʻolōʻihi nui ana i ke ola lawelawe o nā uhi lako.
3. ʻAno paʻa a like hoʻi:ʻO ka hopena o ke kaʻina hana electrofusion i kahi ʻano kūloko paʻa a me ka haku like ʻana o ka piliki, me ka ʻole o nā kīnā e like me nā pores a me nā māwae. Loaʻa iā ia ka nui o ka density, ka haʻahaʻa o ka omo wai a me ka conductivity thermal paʻa, e hōʻemi ana i ka pilikia o ka spalling structural i nā mahana kiʻekiʻe.
4. Ka pololei o ke ana hiki ke hoʻokele ʻia:Hana ʻia ka ʻoki pololei ma hope o ka hoʻomaʻalili ʻana a me ke kūkulu ʻana, me nā kikoʻī maʻamau a me ke ʻano kūikawā. He pālahalaha kiʻekiʻe ka piliki a he liʻiliʻi ka hewa o ka nui, e hoʻololi ana i nā koi masonry pololei o nā umu like ʻole a e hōʻemi ana i ka paʻakikī o ke kūkulu ʻana.
5. Paʻa maikaʻi o ka wela:Hiki iā ia ke hoʻololi i ka loli o ke anu a me ka wela ma lalo o nā kūlana hana wela kiʻekiʻe me kahi coefficient hoʻonui wela kūpono. ʻAʻole maʻalahi ka haki a i ʻole ka haki ʻana ma muli o nā loli wela koke, e hōʻoiaʻiʻo ana i ka pono o ke kūkulu ʻana o nā uhi umu.

AZS-33:ʻO ke ʻano microstructure mānoanoa o AZS33 e hoʻoikaika ai i nā piliki i ka pale ʻana i ka wai aniani, a ʻaʻole maʻalahi ka hana ʻana i nā pōhaku a i ʻole nā hemahema ʻē aʻe i loko o ka umu aniani. He huahana hoʻohana nui ʻia ia i nā umu hoʻoheheʻe aniani, a kūpono nui ia no ka ʻano o luna o ka loko hoʻoheheʻe, nā piliki paia o ka loko a me nā piliki paving o ka loko hana, a me ke alo, a pēlā aku.
AZS-36:Ma waho aʻe o ka loaʻa ʻana o ka eutectic like me AZS33, ʻoi aku ka nui o nā kristal zirconia e like me ke kaulahao o nā piliki AZS36 a me ka haʻahaʻa o ka pae aniani, no laila ua hoʻonui hou ʻia ke kūpaʻa ʻana o nā piliki AZS36 i ka pala, no laila kūpono ia no nā wai aniani me nā kahe wikiwiki a i ʻole nā wahi mahana kiʻekiʻe.

Nā Nīnau i Nīnau Pinepine ʻia
Pono kōkua? E kipa aku i kā mākou mau kahua kākoʻo no nā pane i kāu mau nīnau!
He mea hana maoli mākou, ua loea kā mākou hale hana i ka hana ʻana i nā mea refractory no nā makahiki he 30 a ʻoi. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka hoʻohuihui kemika a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia maikaʻi me nā waiwai. Inā he mau koi kūikawā kāu, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokō iā lākou.
Ma muli o ka nui, ʻokoʻa ka manawa hoʻouna. Akā ke hoʻohiki nei mākou e hoʻouna koke me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā laʻana manuahi.
ʻAe, ʻoiaʻiʻo, ua ʻoluʻolu ʻia ʻoe e kipa i ka hui ʻo RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hoʻonā e like me kou kūlana.
Ua hana mākou i nā mea refractory no nā makahiki he 30 a ʻoi, loaʻa iā mākou ke kākoʻo loea ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kilns like ʻole a hāʻawi i ka lawelawe hoʻokahi.
