ʻO ke koho ʻana o nā mea refractory no ka uhi ʻana o ka umu ahi hoʻoheheʻe alumini

Nui nā ʻanoiʻoihana ʻoihanaaluminummhoʻokiʻekiʻefʻūmū, ka umu hoʻomanaʻo nui, ka umu induction, a me nā mea'ē aʻe,ʻo ka lukuʻiaʻana o ke kapuahi kapuahi ka mea nui i ke komoʻana o ka wai alumini a me ka holoiʻana i kona uhi me nā pōhaku lepo, nā pōhaku lepo alumina kiʻekiʻe a me ka corundum mullite brick masonry, akā me nā alumina refractory castables kiʻekiʻe. refractory plastic lining, ma muli o ka hoʻohana ʻana i nā kūlana maikaʻi, ʻoi aku ka lōʻihi o ke ola o ka umu.

Mua o na mea a pau, refractories no reflector umu ahi, reflector kapuahi i maheleia i paa a tilting 'ano, me ka hoʻohana kinoea a kaumaha aila e like me ka wahie.Aluminum hooheheeia ua paa noonoo kapuai, non-hana papa me ka refractory puluniu manao a me ka palolo insulation refractory brick masonry, hooheheeia loko ma luna o ka hapa o ka papa hana me ka pālolo pōhaku lepo, akā, i loaʻa kiʻekiʻe alumina refractory castables a prefabricated poloka.Heheʻe wai papa hana e like me ka hoʻohana 'ana i nā 'ano hana like 'ole, kona mea no hoi okoa, me ka hoʻohana Al2O3 maʻiʻo o ka oi ma mua o 75% o ka kiʻekiʻe alumina refractory brick masonry a oi aku, akā, i loaʻa Al2O3 maʻiʻo o 80% ma waho o ke kiʻekiʻe alumina refractory castables. ninini ʻia i loko o ka papa hana holoʻokoʻa, i ka wā e hoʻoheheʻe ai i ka alumini metala maʻemaʻe kiʻekiʻe, ʻo ka papa hana wai hoʻoheheʻe he kiʻekiʻe maʻemaʻe mullite brick, zircon brick a corundum brick masonry.Aluminum discharge waha, kahe alumini pahu a me kona liner, i mea e pale aku i ke komo a me ka erosion o ka alumini wai, me ka nui silicon carbide brick masonry.

A laila ʻo ka umu induction me nā mea refractory, maʻamau me nā pōhaku lepo a i ʻole ʻekolu pae o ka alumina kiʻekiʻe refractory brick masonry.ʻO ka lalo o ka umu ahi i kekahi manawa e ninini ʻia me ka alumina kiʻekiʻe refractory castables mua, a laila masonry kiʻekiʻe alumina refractory bricks.Ke emi ka mana o ka umu induction ma mua o 10t, hiki ke hana ʻia kona kino lining me ka alumina refractory kiʻekiʻe a i ʻole nā ​​​​mea kuʻi kuʻi me Al2O3 ma kahi o 75%, a loaʻa pū kekahi corundum refractory castable a maloʻo hoʻi.Ka liner a puni ka inductor coil o kakapuahi hoohehee aluminiua ninini ʻia me nā corundum refractory castables holoʻokoʻa.

Hoʻomoe ʻia ka pahu 10mm asbestos a i ʻole ka fiber refractory, a laila masonry pālolo thermal insulation refractory brick a i ʻole bleaching bead brick no ka papa insulation;ka papa hana a me ka wili a puni ka liner maʻamau i hoʻohana ʻia ka pālolo refractory kuʻi mea kuʻi, loaʻa pū ka pālolo refractory ninini mea ma ka pae ninini, nui slot induction kapuahi hana papa, loaʻa pū Al2O3 maʻiʻo oi ma mua o 55% o kiʻekiʻe alumina refractory brick masonry.

ʻO ka umu hoʻoheheʻe ʻauʻau ʻauʻau ʻauʻau ʻaʻole i hana ʻia me ka pālolo insulation refractory bricks, drifting bead brick a insulation plate masonry.Loaʻa nō hoʻi i ka nui nui o 0.8g/cm3 kukui refractory castable piha ninini;ʻO ka wai hoʻoheheʻe e hana ana me ka Al2O3 ma kahi o 80% o ka alumina kiʻekiʻe refractory brick masonry, akā loaʻa nō hoʻi i ka nui nui o 2.4g/cm3 kiʻekiʻe alumina refractory ahi castable ninini.ʻO ka papa hana ma luna o ka wai hoʻoheheʻe ʻia ma ke ʻano maʻamau me nā pōhaku lepo a i ʻole nā ​​​​poloka i hana mua ʻia, a hiki ke kuʻi ʻia me ka plastic refractory alumina kiʻekiʻe.

ʻO ka lalo, ka paia a me ke kaupaku o ka umu ahi keʻena i haku ʻia.Hiki ke hoʻohana pū ʻia me ka umu ahi noʻonoʻo alumina.ʻO kāna mea e uhi ai i ka umu ahi he pōhaku lepo a me nā pōhaku lepo refractory alumina kiʻekiʻe.

Aluminum hoʻomaʻemaʻe kapuahi pā pā me ka magnesium brick masonry, ʻo ke koena o nā ʻāpana me nā pōhaku lepo a me nā alumina refractory kiʻekiʻe, electrolysis, ʻo ka wela o ka pahu ma ke ʻano he 720-800 ℃, haʻahaʻa ka mahana hana, no laila ua lōʻihi ke ola o ka lawelawe.
