Nā Piliki Corundum/Nā Piliki Corundum Mullite
ʻIke Huahana
Piliki CorundumHe mau huahana paʻakikī nā huahana me ka corundum ma ke ʻano he pae crystalline mua, a ʻoi aku ka nui o ka alumina ma mua o 90%.
Hoʻokaʻawale ʻana:Hoʻokaʻawale nui ʻia nā piliki Corundum i nā piliki corundum sintered a me nā piliki corundum i hoʻohui ʻia. Hana ʻia ka mea mua mai ka alumina sintered, aʻo ka mea hope mai ka corundum i hoʻohui ʻia. Hiki ke hana ʻia nā piliki corundum i puhi ʻole ʻia me ka hoʻohana ʻana i ka waikawa phosphoric a i ʻole nā mea hoʻopaʻa ʻē aʻe.
Nā ʻano hana:
Nā Waiwai Kūpaʻa Maikaʻi Loa:ʻOi aku ka mahana o ka palupalu ʻana o nā piliki corundum ma mua o 1700°C, a hiki i kekahi mau piliki chrome corundum ke piʻi i nā mahana ma mua o 1790°C. Noho paʻa lākou i nā wahi wela kiʻekiʻe a ʻaʻole hiki ke hoʻololi a hōʻino ʻia paha.
Ikaika Kiʻekiʻe:ʻO ka ikaika compressive o nā piliki corundum maʻemaʻe kiʻekiʻe i ka mahana o ka lumi he 70MPa-100MPa, ʻoiai ʻo ka ikaika o nā piliki chrome corundum hana kiʻekiʻe ma mua o 150MPa a hiki ke piʻi i ka 340MPa.
Paʻa Kemika Maikaʻi:He kūpaʻa loa nā piliki Corundum i nā ʻōpala waikawa a alkaline paha, nā metala, a me ke aniani hoʻoheheʻe ʻia, a ʻaʻole ia e maʻalahi i nā hopena kemika.
Ke kūpaʻa ikaika i ka ʻino ʻana o ka slag:Eia kekahi laʻana, ʻo ka nui o Cr₂O₃ i loko o nā piliki chrome corundum e pale pono i ka ʻōpala i hoʻoheheʻe ʻia mai ke komo ʻana i loko o ke kino piliki ma o nā pores capillary, e hopena ana i ke kūpaʻa maikaʻi loa i ka ʻino ʻana o ka slag ma mua o nā piliki corundum maʻamau.
Nā Mea Hoʻohui Nui a me nā Mea Maka:
ʻO ka ʻāpana nui o nā piliki corundum he alumina (Al₂O₃), ʻoi aku ka nui ma mua o 90%, a aia kekahi a hiki i ka 99%. ʻO nā mea maka e komo pū me ka alumina sintered a me ka corundum fused. Hiki ke hoʻohui ʻia nā mea mineral ʻē aʻe e hana i nā mea hui pū ʻia, e like me Cr₂O₃ no nā piliki chrome corundum a me ZrO₂ no nā piliki zirconium corundum.
Nā pōhaku lepo Corundum-mullitehe mau piliki paʻa i hui pū ʻia i haku ʻia me ʻelua mau pae paʻa wela kiʻekiʻe: corundum (Al₂O₃) a me mullite (3Al₂O₃・2SiO₂). Hoʻohui lākou i ka ikaika kiʻekiʻe o ka corundum me ke kūpaʻa haʻalulu wela maikaʻi loa o ka mullite, e hoʻolilo ana iā lākou i mea wela kiʻekiʻe e kaulike ana i ka hana a me ke kumukūʻai kūpono.
Nā ʻĀpana Koʻikoʻi a me nā Hiʻohiʻona Kūkulu
ʻO ka Hoʻohuihui Pae Crystalline Nui:ʻO Corundum lāua ʻo mullite nā ʻāpana kristal nui ʻelua, me ka nui o ka alumina ma waena o 70% a 90%, a ʻo ke koena nui ka silicon dioxide (SiO₂). Hoʻohālikelike ka hopena synergistic o nā ʻāpana ʻelua i ka hana.
ʻAno liʻiliʻi:Hoʻolaha ʻia nā ʻāpana Mullite ma waena o nā hua corundum ma ke ʻano o nā kristal ʻano nila a i ʻole nā kristal kolamu, e hana ana i kahi ʻano "corundum skeleton + mullite connection". ʻAʻole wale kēia e hoʻonui i ka ikaika o nā piliki akā pale pū kekahi i nā kaumaha wela ma o nā hakahaka micro-crystal.
Nā Pōmaikaʻi Hana Koʻikoʻi
Ke kūpaʻa haʻalulu wela maikaʻi loa:ʻO kēia kona pono nui. He haʻahaʻa ka coefficient o ka hoʻonui wela o Mullite, a ʻo kona ʻano kristal e like me ke kui e hoʻopili i ke kaumaha i hoʻokumu ʻia e nā loli o ka mahana, e hōʻemi nui ana i ka haki i hoʻokumu ʻia e ka hoʻomaʻalili wikiwiki a me ka hoʻomehana ʻana i nā mahana kiʻekiʻe. ʻOi aku kona hana ma mua o nā piliki corundum maʻemaʻe.
Ka ikaika kaulike a me ke kūpaʻa i ka palaho:ʻO ke alo o ka pae corundum e hōʻoiaʻiʻo ana i ka ikaika kiʻekiʻe ma nā mahana lumi a me nā mahana kiʻekiʻe, me ka hāʻawi pū ʻana i ke kū'ē maikaʻi i ka slag acidic, ke aniani heheʻe, a me nā mea ʻē aʻe. ʻOiai ʻoi aku ka haʻahaʻa o kona kū'ē alkali ma mua o nā piliki chrome corundum, hāʻawi ia i kahi ākea ākea o nā noi.
Ka hoʻokele wela kūpono:Ke hoʻohālikelike ʻia me nā piliki corundum kiʻekiʻe, hāʻawi ia i kahi conductivity thermal haʻahaʻa me ka mālama ʻana i kahi kekelē o ka insulation, e hōʻemi ana i ka pohō wela i nā lako wela kiʻekiʻe a hana ia i kūpono no nā noi e pono ai ka insulation thermal.

ʻO Shandong Robert New Material Co., Ltd.Aia ma ke kūlanakauhale ʻo Zibo, ka moku ʻo Shandong, Kina, he kahua hana mea refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku ʻana, ka hoʻolālā a me ke kūkulu ʻana i ka umu, ka ʻenehana, a me ka hoʻokuʻu aku i nā mea refractory. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika loea ikaika, ka maikaʻi o ka huahana maikaʻi loa, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma mua o 200 ʻeka a ʻo ka hopena makahiki o nā mea refractory i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea refractory i hoʻohālikelike ʻole ʻia he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory: nā mea refractory alkaline; nā mea refractory silicon alumini; nā mea refractory i hoʻohālikelike ʻole ʻia; nā mea refractory thermal insulation; nā mea refractory kūikawā; nā mea refractory hana no nā ʻōnaehana hoʻolei mau.
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.
