Nā Bricks Mullite māmā 1.0

Hana ʻia nā pōhaku lepo mullite māmā i nā mea refractory kiʻekiʻe kiʻekiʻe, e like me ka gravity kikoʻī i koi ʻia o ka huahana, hoʻohui ʻia nā mea hoʻopihapiha hoʻopihapiha, hoʻokuʻu ʻia a hoʻopaʻa ʻia i ka wela kiʻekiʻe e hana i nā huahana mullite māmā. Me kona kaumaha māmā a me ka maikaʻi o ka hana insulation thermal, hoʻohana nui ʻia nā pōhaku mullite māmā i nā linings refractory o ka wela wela a i ʻole nā papa insulation o nā mea wela like ʻole, e hana ana i nā kūlana no ka hoʻomaikaʻi ʻana i ka nui o ka hoʻohana ʻana i ka ikehu o nā lako.

ʻO ka wehewehe ʻana o ka Brick Mullite māmā

ʻO nā mea hoʻoheheʻe alumina kiʻekiʻe me ka mullite e like me ke ʻano kristal nui maʻamau i loaʻa ka ʻike alumina o 50% -75%. Hiki ke piʻi ka mahana refractory o nā pōhaku māmā mullite ma luna o 1790 ℃. ʻO ka wela hoʻomaka ʻana o ka haʻahaʻa he 1600-1700 ℃. ʻO ka pale wela o ka lumi he māmā 70-260MPa. Kūleʻa haʻalulu wela maikaʻi. ʻElua ʻano: nā pōhaku lepo mullite sintered a me nā pōhaku lepo mullite fused.

Hana ʻia nā pōhaku lepo mullite me ke kiʻekiʻe-alumina bauxite clinker ma ke ʻano he kumu nui, me ka liʻiliʻi o ka pālolo a i ʻole ka bauxite maka e like me ka mea hoʻopili, a ua hana ʻia a hoʻopaʻa ʻia. Hana ʻia nā pōhaku lepo mullite me ka bauxite alumina kiʻekiʻe, ka alumina ʻoihana a me ka pālolo refractory, me ka lanahu a i ʻole coke mau mea i hoʻohui ʻia ma ke ʻano he mea hoʻemi. Ma hope o ka hoʻokumu ʻana, hana ʻia lākou e ke ʻano hoʻohaʻahaʻa fusion. ʻOi aku ka nui o nā kristal o fused mullite ma mua o nā mullite sintered, a ʻoi aku ka maikaʻi o ke kūʻē ʻana o ka wela ma mua o nā huahana sintered. ʻO kā lākou hana wela kiʻekiʻe e hilinaʻi nui ʻia i ka ʻike o ka alumina a me ke kūlike o ka hāʻawi ʻana i ka pae mullite a me ke aniani.

ʻO kahi mea refractory kiʻekiʻe-alumina me ka mullite (3Al2O3 · 2SiO2) ma ke ʻano he aniani nui. ʻO ka ʻike alumina maʻamau ma waena o 65% a me 75%. Ma waho aʻe o ka mullite, loaʻa i ka hui mineral kekahi wahi liʻiliʻi o ka māhele aniani a me ka quartz me kahi haʻahaʻa alumina haʻahaʻa; a me kahi mea liʻiliʻi o ka corundum me kahi mea alumina kiʻekiʻe. Hiki ke hoʻohana pololei ʻia nā pōhaku lepo mullite māmā no nā lining kiln kiʻekiʻe, a ua hoʻohana nui ʻia i kēia manawa i nā kiln shuttle, roller kilns, aniani a me ka petrochemical kiln linings.

ʻO nā ʻāpana kino a me nā kemika o nā pōhaku mullite māmā penei:

Nā hiʻohiʻona mullite brick māmā:

ʻO ka umu ahi Ferrosilicon kahi umu uila ʻoihana e hoʻopau i ka mana nui a he ʻano o ka umu ahi i hoʻopaʻa ʻia. ʻO ka ferrosilicon furnace e pili ana i ka pūpū kapuahi, ka uhi o ka umu ahi, ka uhi o ka umu, ka ʻupena pōkole, ka ʻōnaehana hoʻoluʻu wai, ka ʻōnaehana o ka uahi, ka ʻōnaehana hoʻoneʻe lepo, ka pūpū electrode, ka hoʻokuʻu ʻana i ke kaomi electrode a me ka ʻōnaehana hāpai, ka hoʻouka ʻana a me ka wehe ʻana o ka ʻōnaehana, ka mea hoʻoponopono, nā mea puhi ahi, hydraulic. ʻōnaehana, transformer A me nā mea uila like ʻole, a me nā mea ʻē aʻe, koi nui ka hoʻohana ʻana i nā mea refractory.

I ka makahiki 2006, ua hoʻokumu ʻia kā mākou hale hana ma Yuzhou, ke kumu kumu kumu. ʻO ka bauxite alumina kiʻekiʻe i loko o ka ʻoihana refractory e pili ana i ka ʻaila bauxite me kahi maʻiʻo Al₂O₃ calcined ma mua o 48% a me kahi haʻahaʻa Fe₂O₃ haʻahaʻa.

Hoʻopili ʻia i:

ʻO ke aniani hoʻoheheʻe ʻana i ka umu pōhaku ma luna o ka hale kanal, nā papa hoʻololi, ka hoʻoponopono ʻana i ka hale kiln ma luna, nā pōhaku lepo hoʻoheheʻe E-aniani. ʻO nā kiln ahi, nā kiln hoʻoheheʻe, nā mea hoʻomaʻemaʻe, nā mea hoʻomehana, a me nā mea wela ʻē aʻe. Nā wahi noi: ʻoihana seramika, ʻoihana aniani, ʻoihana kila, ʻoihana petrochemical, ʻoihana aluminika, a me nā ʻoihana ʻē aʻe.
