ʻO ke kuleana nui o nā piliki insulation ka mālama ʻana i ka wela a me ka hōʻemi ʻana i ka nalowale o ka wela. ʻAʻole pili pono nā piliki insulation i ka lapalapa, a pili pono nā piliki ahi i ka lapalapa. Hoʻohana nui ʻia nā piliki ahi e kū i ka lapalapa o ka i kālua ʻia. Ma ke ʻano laulā, ua māhele ʻia i ʻelua ʻano, ʻo ia hoʻi nā mea refractory Unshaped Indefinite a me nā mea refractory Shaped.
Mea Paʻakikī ʻAno ʻole
ʻO nā mea refractory castables he mau ʻāpana pauka i hui pū ʻia me nā ʻano aggregates a i ʻole aggregates a me hoʻokahi a ʻoi aku paha nā mea hoʻopaʻa. Pono e hui pū ʻia ka hoʻohana me hoʻokahi a ʻoi aku paha nā wai, me ka wai ikaika.
Mea Paʻakikī i ke ʻAno
Ma nā kūlana maʻamau, loaʻa ke ʻano o nā pōhaku refractory i kahi nui maʻamau, hiki ke hoʻopilikino ʻia e like me nā koi o ka mea kūʻai aku.
Nā ʻokoʻa nui ma waena o nā bricks insulation a me nā bricks ahi
1. Hana Hoʻokaʻawale
ʻO ka conductivity thermal o nā piliki insulation maʻamau he 0.2-0.4 (awelika wela 350±25°C)w/mk, a ʻoi aku ka conductivity thermal o ka piliki ahi ma mua o 1.0 (awelika wela 350±25°C)w/mk No laila, ʻoi aku ka maikaʻi o ka hana insulation thermal o ka piliki insulation ma mua o nā piliki ahi.
2. Kūpaʻa ʻole
ʻO ke kūpaʻa o ka piliki hoʻokaʻawale ma lalo o 1400 degere, a ʻo ke kūpaʻa o ka piliki refractory ma luna o 1400 degere.
3. Ka nui o ka paʻa
He māmā nā piliki hoʻokaʻawale, ʻo ka nui o nā piliki hoʻokaʻawale he 0.8-1.0g/cm3 a ʻo ka nui o nā piliki paʻa ʻole ma mua o 2.0g/cm3.
Hopena
I ka hōʻuluʻulu manaʻo, he ikaika mechanical kiʻekiʻe ka piliki refractory, lōʻihi ke ola lawelawe, kūpaʻa kemika maikaʻi, ʻaʻohe hopena kemika me ka mea a me ke kūpaʻa wela kiʻekiʻe maikaʻi, a hiki i ka mahana wela kiʻekiʻe loa ke hiki i 1900°C. He kūpono loa nā piliki refractory no ka hoʻohana ʻana i nā mea hoʻololi hoʻololi mahana kiʻekiʻe-haʻahaʻa, nā mea hoʻoponopono hou, nā mea hoʻololi hydrogenation, nā pahu desulfurization, a me nā umu methanation o nā hale hana mea hoʻouluulu kemika e pāʻani i kahi hana i ka hoʻopuehu ʻana i nā wai kinoea, ke kākoʻo ʻana, ka uhi ʻana, a me ka pale ʻana i nā mea hoʻoulu. Hiki ke hoʻohana ʻia nā piliki refractory ahi i nā kapuahi wela a me nā lako hoʻololi hoʻomehana i ka ʻoihana kila.
Loaʻa i nā piliki ahi nā pono o ke kiʻekiʻe o ka nui, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa maikaʻi i ka pala, ka coefficient hoʻonui wela haʻahaʻa, ka pono wili kiʻekiʻe, ka walaʻau haʻahaʻa, ke ola lawelawe lōʻihi, a me nā mea haumia ʻole. He mea wili maikaʻi ia e kūpono no nā mīkini wili like ʻole.
He ʻokoʻa loa nā piliki refractory a me nā piliki insulation, ʻaʻole like kā lākou hoʻohana ʻana i ke kaiapuni, ka laulā a me ke kuleana. E hoʻohana ʻia nā mea like ʻole ma nā wahi like ʻole. I ke kūʻai ʻana i nā mea, pono mākou e hoʻoholo i ke ʻano o nā mea refractory i kūpono no kā mākou hoʻohana ponoʻī e like me ko mākou kūlana maoli.
