Nā Piliki Paʻakikī Magnesia
Nā pōhaku paʻa magnesiahe mau mea kūpaʻa alkaline me ka magnesium oxide maʻemaʻe kiʻekiʻe (MgO) ma ke ʻano he mea nui (maʻamau ≥85%) a me ka periclase (MgO) ma ke ʻano he pae crystalline mua. Hāʻawi lākou i nā pono koʻikoʻi e like me ke kūpaʻa kiʻekiʻe a me ke kūpaʻa ikaika i ka erosion slag alkaline, a hoʻohana nui ʻia i nā noi ʻoihana wela kiʻekiʻe e like me ka metallurgy a me nā mea kūkulu hale. ʻO ko lākou palena nui ka pale haʻalulu thermal maikaʻi ʻole.
Hoʻokaʻawale ʻana

Ka paʻakikī—He kiʻekiʻe loa ka paʻakikī o nā piliki magnesium, ʻoi aku ka nui ma mua o 2000°C.
Mahana palupalu o ka ukana—ʻOi aku ka haʻahaʻa o ka mahana hoʻomaka o ka palupalu ʻana o nā piliki magnesia ma mua o ko lākou kūpaʻa ʻole, ma kahi o 1530~1580°C.
He maikaʻi ka hoʻokele wela o nā pōhaku magnesium—He nui nā manawa o ka hoʻoili wela ʻana o nā piliki magnesium ma mua o nā piliki lepo, a e emi ana ko lākou hoʻoili wela me ka piʻi ʻana o ka mahana.
ʻAʻole maikaʻi ke kūpaʻa ʻana o nā piliki magnesium i ka haʻalulu wela—Hiki iā lākou ke kū i 2-3 mau pōʻaiapuni hoʻoluʻu wai wale nō. ʻO kēia ma muli o ko lākou coefficient kiʻekiʻe o ka hoʻonui ʻana o ka thermal a me ka conductivity thermal haʻahaʻa, e hoʻolilo ana iā lākou i mea maʻalahi i ka hoʻoulu ʻana i ke kaumaha thermal koʻikoʻi i ka wā o nā loli wikiwiki o ka mahana.
Ke kū'ē ʻana i ka slag a me ke kū'ē ʻana i ka hydration—He kūpaʻa nā piliki magnesium i ka alkali akā ʻaʻole kūpaʻa i ka waikawa. ʻO ka hoʻokumu ʻia ʻana o ka magnesium ferrite a me ka calcium magnesium olivine e hōʻemi ana i ko lākou kūpaʻa i ka hydration. No laila, he mea nui ka pale wai a me ka pale ʻana i ka makū ma nā kūlana āpau.

ʻOihana Hao a me ke Kila:
Hoʻohana ʻia i loko o nā BOF (Basic Oxygen Furnaces), EAF (Electric Arc Furnaces), a me nā uhi ladle, a me nā mea hoʻohuihui a me nā umu ferroalloy. Kūʻē ia i ka ʻino ʻana mai ke kila heheʻe a me nā ʻōpala alkaline.
ʻOihana Mea Hana Hale:
Hoʻohana ʻia ma ka ʻāpana kuni a me ka ʻāpana hoʻololi o nā umu wili sima, a ma ke ʻano he uhi no nā umu lime. Kūpaʻa ia i ka pala alkali mai ka clinker a me ka holoi ʻana i ka mahana kiʻekiʻe.
ʻO ka Metallurgy ʻaʻole ferrous:
Hoʻohana ʻia e like me nā uhi no nā umu hoʻoheheʻe a me nā umu hoʻomaʻemaʻe no ke keleawe, ka nikala, a pēlā aku. He kūpono ia no nā kūlana wela kiʻekiʻe a me ka pala mai nā metala non-ferrous i hoʻoheheʻe ʻia.
Nā Hana ʻē aʻe:
Hoʻohana ʻia e like me nā uhi no nā lako hana wela loa e like me nā mea hoʻoulu hou o ka umu aniani, nā reactors wela kiʻekiʻe, a me nā mea puhi ʻōpala.
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, 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 kūpaʻa alkaline; nā mea kūpaʻa silicon alumini; nā mea kūpaʻa ʻano ʻole; nā mea kūpaʻa wela insulation; nā mea kūpaʻa kūikawā; nā mea kūpaʻa hana no nā ʻōnaehana hoʻolei mau.
Hoʻohana nui ʻia nā huahana a Robert i nā umu wela kiʻekiʻe e like me nā metala ʻaʻole ferrous, ke kila, nā mea kūkulu hale a me ke kūkulu ʻana, nā kemika, ka mana uila, ka puhi ʻana i nā ʻōpala, a me ka mālama ʻana i nā ʻōpala weliweli. Hoʻohana ʻia hoʻi lākou i nā ʻōnaehana kila a me ka hao e like me nā ladles, EAF, nā umu pahū, nā mea hoʻololi, nā umu coke, nā umu pahū wela; nā umu metallurgical ʻaʻole ferrous e like me nā reverberators, nā umu hoʻemi, nā umu pahū, a me nā umu rotary; nā umu ʻoihana mea kūkulu hale e like me nā umu aniani, nā umu sima, a me nā umu keramika; nā umu ʻē aʻe e like me nā paila, nā mea puhi ʻōpala, ka umu kālua, i loaʻa nā hopena maikaʻi i ka hoʻohana ʻana. Hoʻokuʻu ʻia aku kā mākou huahana i Asia Hikina Hema, Asia Waena, Hikina Waena, ʻApelika, ʻEulopa, ʻAmelika a me nā ʻāina ʻē aʻe, a ua hoʻokumu i kahi kahua hana like maikaʻi me nā ʻoihana kila kaulana he nui. Ke kakali nei nā limahana a pau o Robert i ka hana pū ʻana me ʻoe no kahi kūlana lanakila-lanakila.
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.
