He aha ka Refractory Bricks?

Piliki hoʻopaʻaʻO kahi mea seramika i hoʻohana pinepine ʻia i nā kaiapuni kiʻekiʻe ma muli o ka nele o ka hoʻopau ʻana a no ka mea he insulator kūpono e hōʻemi i ka nalowale o ka ikehu. Hoʻokumu pinepine ʻia nā brick refractory me ka alumini oxide a me ka silicon dioxide. Ua kapa ʻia ʻo "piliki ahi."

Hoʻohui ʻia o ka pālolo Refractory

Pālolo hoʻopaʻapaʻaPono e loaʻa i kahi ʻāpana kiʻekiʻe o ka silicon dioxide "ʻaʻole pōʻino" aaluminikaoxide. Pono e loaʻa iā lākou nā lime pōʻino, magnesium oxide, iron oxide, a me ka alkali.
ʻO Silicon Dioxide: Hoʻopalupalu ʻo Silicon dioxide (SiO2) ma kahi o 2800℉ a hoʻoheheʻe hope loa a lilo i mea aniani ma kahi o 3200℉. Hoohehee ia ma kahi o 3300℉. ʻO kēia wahi palupalu a hoʻoheheʻe kiʻekiʻe e lilo ia i mea nui no ka hana ʻana i nā brick refractory.
Alumina: ʻO ka alumina (Al2O3) ke kiʻekiʻe o ka wela a me ka hoʻoheheʻe ʻana ma mua o ka silicon dioxide. Hoohehee ia ma kahi o 3800℉. No laila, hoʻohana ʻia me ka silicon dioxide.
Lime, magnesium oxide, iron oxide, a me ka alkali: ʻO ka loaʻa ʻana o kēia mau mea ʻino e kōkua i ka hoʻohaʻahaʻa ʻana i ka wela a me ka hoʻoheheʻe ʻana.

ʻO nā hiʻohiʻona nui o nā brick Refractory

Piliki hoʻopaʻas he melemele-keʻokeʻo maʻamau
Loaʻa iā lākou ke kūpaʻa wela maikaʻi a me ka ikaika compressive nui
ʻOkoʻa loa ko lākou ʻano hoʻohui kemika mai ka pōhaku maʻamau
Loaʻa i nā pōhaku makamae ma kahi o 25 a 30% alumina a me 60 a 70% silica.
Loaʻa iā lākou nā oxides o ka magnesium, calcium, a me ka potassium
ʻO nā pōhaku pōhaku refractoryhiki ke hoʻohana ʻia no ke kūkulu ʻana i nā kiln, umu ahi, etc.
Hiki iā lākou ke pale i nā mahana a hiki i 2100 degere Celsius
Loaʻa iā lākou ka mana wela nui e kōkua i nā hale like ʻole e paʻa paʻa i nā wela wela.

Kaʻina hana o nā pōhaku lepo refractory

Hana ʻia nā pōhaku ahi e nā kaʻina hana brick like ʻole, e like me ka hoʻolei ʻana i ka lepo palupalu, kaomi wela, a me ke kaomi maloʻo. Ma muli o nā mea o ka brick ahi, eʻoi aku ka maikaʻi o kekahi mau hana ma mua o nā mea'ē aʻe. Hoʻokumu pinepine ʻia nā pōhaku ahi i kahi ʻano ʻāpana ʻāpana me 9 ʻīniha ka lōʻihi × 4 ʻīniha ākea (22.8 knm × 10.1 knm) a me ka mānoanoa ma waena o 1 iniha a me 3 iniha (2.5 knm a 7.6 knm).

Ka hoʻomākaukau ʻana i nā mea maka:
Nā mea hana refractory: ʻO nā mea maʻamau maʻamau ka alumina, alumini silicate, magnesium oxide, silica, a me nā mea ʻē aʻe.
Hoʻopili: Hoʻohana mau ʻia ka pālolo, gypsum, a me nā mea ʻē aʻe ma ke ʻano he mea hoʻopaʻa e kōkua i ka hui ʻana a me ka hana ʻana o nā ʻāpana maka.
Ka hui ʻana a me ka wili ʻana:
E hoʻokomo i nā mea maka i hoʻomākaukau ʻia i loko o kahi mea hoʻohui no ka hoʻoulu ʻana a me ka hui ʻana e hōʻoia i ka hui ʻana o nā mea maka like ʻole a hui like.
Hoʻopili maikaʻi ʻia nā mea maka i hui ʻia ma o ka mea wili e hana i nā ʻāpana i ʻoi aku ka like a me ka maikaʻi.
Molina:
Hoʻokomo ʻia nā mea i hui ʻia a me ka lepo i loko o kahi mold molding a hana ʻia i ke ʻano o nā pōhaku lepo ma o ka vibration compaction a i ʻole extrusion molding.
Hoʻomaloʻo:
Ma hope o ka hana ʻana, pono e hoʻomaloʻo ʻia nā pōhaku lepo, maʻamau ma ka hoʻomaloʻo ʻana i ka ea a i ʻole ka maloʻo ʻana i loko o kahi keʻena maloʻo, e hoʻoneʻe i ka wai mai nā pōhaku.
Hoʻopaʻa ʻia:
Ma hope o ka maloʻo ʻana, hoʻokomo ʻia nā pōhaku i loko o kahi kiln brick refractory a sintered i nā wela kiʻekiʻe e puhi i ka mea hoʻopaʻa i loko o nā mea maka a hoʻohui i nā ʻāpana e hana i kahi ʻano paʻa.
Hoʻololi ʻia ka mahana a me ka manawa o ka sintering ma muli o nā mea ʻokoʻa a me nā koi, a ke hana maʻamau ʻia ma lalo o nā kūlana wela ma luna o 1500 ° C.

Nā Pōmaikaʻi o ka hoʻohana ʻana i nā Bricks Refractory a i ʻole Bricks Fire

Ke hoʻohana neinā pōhaku ʻaʻahāʻawi i kahi ton o nā pōmaikaʻi. ʻOi aku ke kumukūʻai ma mua o nā pōhaku maʻamau ma muli o ko lākou mau mana insulating kiʻekiʻe. Eia naʻe, hāʻawi lākou i kekahi mau pōmaikaʻi kūʻokoʻa no ka hoʻololi ʻana i kāu hoʻopukapuka hou. ʻO nā mea kūʻai aku i nā Bricks Refractory Basic ma India e hōʻoiaʻiʻo i ka hoʻolako ʻana i nā Bricks Magnesia ma ka ʻāina a hāʻawi lākou i nā pōhaku refractory me nā pono e hiki mai ana:

ʻO ka hoʻopololei maikaʻi loa
Hoʻohana nui ʻia nā brick refractory no kā lākou mau waiwai insulating kupaianaha. Kāohi lākou i ke komo ʻana o ka wela. Mālama lākou i ka hale i ka ʻoluʻolu i ke kauwela a me ka hoʻoilo.

ʻOi aku ka ikaika ma mua o nā brick maʻamau

ʻOi aku ka ikaika o nā pōhaku refractory ma mua o nā pōhaku maʻamau. ʻO ia ke kumu i ʻoi aku ka lōʻihi ma mua o nā pōhaku lepo maʻamau. He māmā hoʻi lākou.

ʻO kēlā me kēia ʻano a me ka nui
ʻO nā mea kūʻai aku i nā Bricks Refractory Basic ma India e hōʻoiaʻiʻo i ka hoʻolako ʻana i nā Bricks Magnesia ma ka ʻāina a hāʻawi lākou i nā pōhaku refractory customizable. ʻO ka hapa nui o nā mea hana a me nā mea hoʻolako e hāʻawi i nā pōhaku pilikino i ka nui a me nā ana i makemake ʻia i nā mea kūʻai.

He aha nā Bricks Refractory i hoʻohana ʻia no?

ʻO nā pōhaku pōhaku refractorye ʻimi i ka noi ma nā wahi i koʻikoʻi ka insulation thermal. Aia kēia laʻana i nā kapuahi. He kūpono lākou no ka ʻaneʻane o nā kūlana ʻino loa. Nui nā mea hoʻomohala kaulana i hoʻohana i kēia mau pōhaku lepo i nā hana kūkulu hale. I nā kūlana wela, mālama nā brick refractory i ke anuanu a me ke anuanu. Mālama pū lākou i ka mahana o ka hale.
No nā mea hana hale, e like me nā umu, nā grills, a me nā kapuahi, ʻo nā brick refractory i hoʻohana pinepine ʻia me ka pālolo i loaʻa ka nui o ka alumini oxide a me ka silicon dioxide, nā mea hiki ke kū i nā wela kiʻekiʻe. Loaʻa i ka alumini oxide nā waiwai hoʻomanaʻo, ʻoiai ʻo ka silicon dioxide kahi insulator maikaʻi loa. ʻOi aku ka nui o ka alumini oxide i loko o ka hui ʻana, ʻoi aku ka kiʻekiʻe o ka wela e hiki ai i ka brick ke kū (kahi noʻonoʻo pono no ka hoʻohana ʻana i ka ʻoihana) a ʻoi aku ka nui o ka pipiʻi. ʻO ke kala ʻeleʻele ʻeleʻele ka silikon dioxide, ʻoiai ʻo ka alumini oxide he kala melemele māmā.

He mea nui ia e hoʻokūpaʻa i ka wā e hoʻolālā ai a kūkulu paha i nā hale e pili ana i ke ahi, pono ʻoe e makaʻala inā pili nā mea i hoʻohana ʻia me nā lula kūloko. He kumukūʻai liʻiliʻi kēia e uku ai no ka pale ʻana i nā poho waiwai a i ʻole nā ​​pōʻino koʻikoʻi. Pono mau e ʻimi i ka ʻōlelo aʻo mai nā poʻe akamai a me nā mea hana.
