ʻIkepili Hui
ʻO Shandong Robert New Material Co., Ltd. Aia ma Zibo City, Shandong Province, Kina, kahi 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 huahana makahiki o nā mea pale ʻino i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea pale ʻino 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.
