Ua māhele ʻia ka umu hana kalapona ʻeleʻele i ʻelima mau uhi nui i loko o ke keʻena kuni, ka ʻāʻī, ka ʻāpana hana, ka ʻāpana anu wikiwiki, a me ka ʻāpana noho.
ʻO ka hapa nui o nā wahie o ka umu hana kalapona ʻeleʻele he ʻaila kaumaha ka hapa nui, a hoʻohana ʻia nā mea maka e like me ka hui hydrocarbon. I ka wā o ke kaʻina hana, paʻakikī ka lewa o ka wahie e puhi ana i loko o ka umu hana, ʻo nā mea maka he decomposition thermal, ka spray lanahu hoʻoluʻu, a me ka wahie a me ka wela o nā mea maka. ʻO nā tile pale ahi i hoʻohana ʻia e ka decomposition e hana i nā ʻano noʻonoʻo kino like ʻole ma nā mea hana Fire Brick Kina. Hiki i ka mahana hoʻohana o ka uhi o loko o ka umu hana ke hiki i 1600 ~ 1700 ° C, a wikiwiki loa ka wikiwiki o ka hoʻomehana ʻana i loko o ka umu. ʻOi aku ka mahana ma ka hopena o ka puʻu ma ka hopena o ka puʻu ma luna o 1700 ℃, a aia ka holo ʻana o ka ea. ʻO kekahi mau wahi wela kiʻekiʻe a hiki i ka 1900 ℃. I kekahi manawa ua hoʻololi ʻia nā kapuahi a me nā huahana like ʻole ma muli o nā kumu hana, a e komo pū ka mahu wai i loko o ka ea i loko o ka uhi o ka umu a puhi i ka pipeline aila.
ʻO nā tile refractory i hoʻohana pinepine ʻia i loko o ka umu hana ʻeleʻele kalapona i hoʻopaʻa ʻia me nā pōhaku alumini a me silicon, nā pōhaku jade paʻa, nā pōhaku jade chromium-duty a me nā tile refractory pheasant. ʻO nā pōhaku alumini a me silicon he alumini kiʻekiʻe, pōhaku mullite, nā pōhaku jade paʻa, a pēlā aku.; Loaʻa i nā pōhaku jade ahi Chromium-like jade nā mea hoʻohui chromium like ʻole, nā tile refractory composite me ka sintering wela kiʻekiʻe, a me nā tile refractory pheasant me ka jade aerobic chromium rigidity.
Aia kekahi mau umu hana kalapona ʻeleʻele e hoʻohana ana i nā piliki hui silicon carbide no ka hana pōhaku. E hoʻohana ʻia ka ʻāpana haʻahaʻa no ka hana pōhaku me nā piliki alumini kiʻekiʻe a i ʻole nā piliki lepo. Aia ka mahana ma kahi o 1550 a 1750 ℃. Ma ka ʻāpana o ke kāʻei hoʻoluʻu ʻaʻole i ʻoi aku ma mua o 1300 ℃, hoʻohana ʻia kahi piliki alumina kiʻekiʻe me ka nui o ka alumini ma waena o 65-70% no ka hana pōhaku ma nā mea hana Fire Brick Kina. Ma nā wahi me ka mahana ma 1750 ~ 1925 ℃, ua koho ʻia nā tile kū'ē jade chromium-ganging me ka hana seismic kū'ē i ka wela no ka hana pōhaku.
Aia ka mahana kiʻekiʻe loa ma kahi o 2000 ~ 2100 ℃, a pono e hoʻohana ʻia nā piliki ZRO2 maʻemaʻe e pale aku i ke ahi no ka hana ʻana i ka pōhaku, no ka mea, he kiʻekiʻe ke kiko heheʻe o nā piliki refractory i loaʻa ka ore, nui ka nui, liʻiliʻi ka conductivity thermal, a me ke kūpaʻa kemika maikaʻi, akā he kiʻekiʻe ke kumukūʻai o nā tile piliki ZRO2 e pale aku i ke ahi.
I ka pōkole, ua ʻōlelo aku nā mea hana China Fire Brick e hoʻohana ʻia nā pōhaku refractory like ʻole o nā mea like ʻole ma nā wahi mahana like ʻole, no laila inā e hoʻemi ʻia ke kumukūʻai hana, hiki iā ia ke hoʻokō i nā pono o ka lining.
