Nā Piliki Paʻa Alumina Kiʻekiʻe: Nā Mālama Hilinaʻi o nā ʻOihana Wela Kiʻekiʻe

Ma ke kahua o nā ʻoihana wela kiʻekiʻe, ʻo ka hana o nā mea e hoʻoholo pololei ai i ke kūpaʻa a me ka pono o ka hana ʻana.Nā pōhaku lepo paʻa alumina kiʻekiʻe, ʻoiai he mau mea refractory kiʻekiʻe i hana ʻia mai ka bauxite alumina kiʻekiʻe, ua lilo ia i koho kūpono no nā ʻoihana wela kiʻekiʻe he nui me kā lākou hana koʻikoʻi, e pale ana i ka hoʻomohala ʻana o ka metallurgy honua, nā mea kūkulu hale, nā kemika a me nā ʻoihana ʻē aʻe.

ʻO nā pono nui o nā piliki refractory alumina kiʻekiʻe e pili ana i kā lākou ʻano hana kūikawā a me ke kaʻina hana. Hana ʻia kēia mau piliki mai ka clinker bauxite alumina kiʻekiʻe me ka nui o ka alumina ʻaʻole i emi iho ma mua o 48% ma ke ʻano he aggregate, i hui pū ʻia me nā mea hoʻopaʻa ma nā ʻano like ʻole, a laila hana ʻia, hoʻomaloʻo ʻia, a puhi ʻia i nā mahana kiʻekiʻe. Loaʻa i nā piliki refractory alumina kiʻekiʻe ka refractoriness maikaʻi loa, hiki ke kū i nā mahana kiʻekiʻe mai 1770°C a i 1790°C. ʻOiai ma nā wahi wela kiʻekiʻe loa, hiki iā lākou ke mālama i ke kūpaʻa o ke ʻano, e pale pono ana i ka ʻānai ʻana o nā mahana kiʻekiʻe ma nā lako. ʻO kā lākou mahana palupalu kaumaha maikaʻi e hōʻoiaʻiʻo ʻaʻole lākou e maʻalahi i ka deformation a me ka hiolo ma lalo o kekahi kaomi a me nā mahana kiʻekiʻe, e hāʻawi ana i nā hōʻoia hilinaʻi no ka hana paʻa o nā lako wela kiʻekiʻe. Eia kekahi, loaʻa i nā piliki refractory alumina kiʻekiʻe ke kūpaʻa haʻalulu thermal maikaʻi loa, e hiki ai iā lākou ke mālama i ka hana paʻa i ka wā o nā loli mahana pinepine, e hōʻemi ana i ka haki a me ka spalling i hoʻokumu ʻia e ke kaumaha wela a hoʻolōʻihi i ko lākou ola lawelawe. Loaʻa iā lākou ke kūpaʻa ikaika i nā mea kemika like ʻole. Inā paha he ʻōpala i loko o ke kaʻina hana metallurgical a i ʻole nā ​​​​kinoea ʻino i ka hana kemika, he paʻakikī ke hana i ka hōʻino nui iā lākou.

He nui nā ʻano hana o nā piliki refractory alumina kiʻekiʻe. I ka ʻoihana metallurgical, he mau mea nui lākou no nā uhi o nā umu hana kila, nā umu hana hao, a me nā umu hoʻomehana hou. Hiki iā lākou ke pale pono i ka ʻino ʻana o ke kila a me ka slag i hoʻoheheʻe ʻia i ka mahana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka holomua mālie o ke kaʻina hana hoʻoheheʻe a hoʻomaikaʻi i ke ola lawelawe o nā lako a me ka pono hana. I ka ʻoihana mea hale, hoʻohana pinepine ʻia nā piliki refractory alumina kiʻekiʻe i nā lako e like me nā umu rotary sima a me nā umu hoʻoheheʻe aniani. I nā wahi me nā mahana kiʻekiʻe, ka holoi ʻana i ka ea wikiwiki, a me ka abrasion mea, hiki iā lākou ke mālama i ka hana maikaʻi, e kākoʻo ana i ka hana paʻa o ka hana ʻana i nā mea hale. I ka ʻoihana kemika, he kuleana koʻikoʻi nā piliki refractory alumina kiʻekiʻe i nā umu hana wela kiʻekiʻe a me nā gasifiers. Me ko lākou kūpaʻa maikaʻi loa i ka palaho kemika, hōʻoiaʻiʻo lākou i ka palekana a me ka pono o ke kaʻina hana hana kemika.

Ua lako mākou me nā lako hana holomua a me kahi ʻōnaehana kaohi maikaʻi koʻikoʻi. Nānā pono ʻia kēlā me kēia loulou, mai ke kūʻai ʻana i nā mea maka a hiki i ka lawe ʻana i nā huahana i hoʻopau ʻia. Ma ka hoʻohana ʻana i nā kaʻina hana hana alakaʻi honua, hōʻoia mākou e kūlike ka maikaʻi o nā piliki refractory alumina kiʻekiʻe i nā kūlana honua. I ka manawa like, hāʻawi pū mākou i ke kākoʻo loea ʻoihana a me nā lawelawe ma hope o ke kūʻai aku. Wahi a nā pono like ʻole o nā mea kūʻai aku, hāʻawi mākou i nā hoʻonā pilikino e hōʻoia i ka hiki i nā piliki refractory alumina kiʻekiʻe ke hana maikaʻi loa i nā noi kūpono.

ʻO ke koho ʻana i kā mākou mau piliki refractory alumina kiʻekiʻe ke koho ʻana i ka maikaʻi a me ka hilinaʻi. Inā makemake ʻoe i nā kūʻai nui a i ʻole nā ​​​​​​mea refractory ʻoihana, hiki iā mākou ke hoʻokō i kāu mau koi. Hoʻokipa maikaʻi mākou i nā mea kūʻai mai nā wahi a puni o ka honua e hoʻokaʻaʻike mai iā mākou a hana pū e hana i kahi wā e hiki mai ana no ka ʻoihana wela kiʻekiʻe!
