wehewehe huahana

ʻO ka mea maka i hoʻohana ʻia i nā huahana chromium corundum series kahi hopena paʻa i hoʻohui ʻia e ka hoʻoheheʻe ʻana o ka alumina kiʻekiʻe a me ka chromium oxide i kekahi ʻāpana.ʻO ka mea maka nui ka bauxite kiʻekiʻe (a i ʻole alumina ʻenehana) ma ka hoʻohui ʻana i ka nui kūpono o ka chromite a hoʻemi ʻia.Hoʻoheheʻe ʻia ka mea hoʻoheheʻe i kahi wela kiʻekiʻe i loko o kahi umu uila, a ninini ʻia ka chromium i hoʻoheheʻe ʻia i loko o ka mold e hoʻomālili mālie ʻia, a laila hana ʻia ma hope o ka annealing..

Ua kapa ʻia ʻo chrnmecorundum refractory huahana i hoʻohui ʻia ʻo chrnmecorundum refractory.ʻO kahi huahana refractory i hoʻokuʻu ʻia me ka hopena paʻa o ka alumina a me ka chromium oxide a me kahi mea liʻiliʻi o ka spinel, nona ka 60% a 87% o ka alumina a me 30% o ka chromium oxide.ʻO 3.2-3.9g / cm3 ka nui o ka nui; ʻoi aku ka kiʻekiʻe o ka ikaika o ka wela, ke hoʻohālikelike ʻia me nā ʻano refractory corundum ʻē aʻe, ʻoi aku ka ikaika o ka corrosion resistance o ke aniani hehee.Hiki ke hoʻohana ʻia e like me ka uhi o ke kiln e pili pono ana me ke aniani hoʻoheheʻe ʻia.

Hoʻohana nui ʻia ka Chromium corundum refractories i ka uhi ʻana o ka lanahu-wai slurry pressurized gasifier, ladle hoʻomaʻemaʻe i ka umu ahi a me ke kalapona ʻeleʻele reactor lining, ʻoihana petrochemical slag gasification furnace lining a me ke aniani melting furnace lining, etc., a hiki ke hoʻohana ʻia no ka hoʻomehana ʻana i ka chrome. ʻO ka pōhaku lepo corundum no ka umu he mea pono ʻole i ka ʻoihana wela kiʻekiʻe.

ʻO AL203 a me Cr2O3 no ka hale corundum, ʻo ka radius o Cr3+ he 0.620, a ʻo ka radius o AL3+ ʻo 0.535.E like me ka empirical formula:

Ma muli o ka emi o ka ʻokoʻa ma waena o Cr3+ a me AL3+ ion radii ma lalo o 15%, hiki i nā ion Cr ke hoʻomau a pau ʻole ke hoʻololi i ka AL ma ka lattice AL203, e hana ana i kahi hopena paʻa paʻa mau ʻole.

Ua like ke ano aniani o Cr203 a me AL203, a okoa ka radius ionic e 13.7%.No laila, hiki iā Cr203 a me AL203 ke hana i ka hopena paʻa ʻole i ka wela kiʻekiʻe.Mai ka hiʻohiʻona o ka laina wai-paʻa paʻa, me ka piʻi ʻana o ka ʻike Cr203, piʻi pū ka mahana i hoʻomaka ai ka puka wai.No laila, ʻo ka hoʻohui ʻana i kahi nui kūpono o Cr203 i ka AL203 hiki ke hoʻomaikaʻi nui i nā waiwai mechanical a me ka hana lawelawe wela kiʻekiʻe o nā corundum refractory.

Hiki iā Cr203 ke hana i kahi hui hoʻoheheʻe kiʻekiʻe a i ʻole he eutectic me kahi mahana hoʻoheheʻe kiʻekiʻe me nā oxides maʻamau.No ka laʻana, FeO·Cr203 spinel i hana ʻia e Cr203 a me Feo kahi helu heheʻe e like me 2100 ℃;Hiki iā Cr203 a me AL203 ke hana i ka hopena paʻa mau.Eia kekahi, hiki i ka Cr203 ke hoʻonui nui i ka viscosity o ka slag a hoʻemi i ka wai o ka slag, a laila e hōʻemi i ka corrosion o ka slag i ka refractory.No laila, ʻo ka hoʻohui ʻana i ka nui kūpono o Cr203 i ka mea refractory hiki ke hōʻemi nui i ka spalling structural spalling o ka mea uhi i ka umu i hana ʻia e ka pala.ʻAʻohe mea maʻamau maʻamau ma waena o ka hiki ke corrosion o ka slag i ka chromium corundum refractory a me ke kumu o ka slag.

ʻO ka chromium corundum brick i hana ʻia me ka chromium corundum refractory mea i loko o ka umu.I ka 2 o ka slag basicity, ʻoi aku ka maikaʻi o ka chromium corundum brick i ka hao slag corrosion;inā he 0.2 ka nui o ka slag, ʻo ka hohonu o ka corrosion o ka slag keleawe i ka chromium corundum brick ʻO ka mea liʻiliʻi loa;inā he 0.35 ka nui o ka pala, ʻo ka hohonu o ka ʻino o ke kino i ka chrome corundum brick ka mea liʻiliʻi loa;i ka 0.3 o ke kumu o ke alakai, o ka manoanoa o ke koena ka mea nui a me ka hohonu o ka papa hana, o ka erosion a me ka papa komo ka mea liilii loa.I ka 0.37 o ka alkalinity slag, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion o nā chrome corundum bricks.

ʻO kā mākou ʻimi a me ka manaʻo hoʻonohonoho ʻo ia ka "hoʻokō mau i kā mākou mea kūʻai aku".Ke hoʻomau nei mākou i ka loaʻa ʻana a me ka hoʻolālā ʻana a me ke kāʻei ʻana i nā mea kūʻai kiʻekiʻe kiʻekiʻe kiʻekiʻe no kā mākou mea kūʻai mua a me nā mea kūʻai hou aku a ʻike i kahi manaʻo lanakila-lanakila no kā mākou mea kūʻai aku e like me mākou no ka Hoʻouna wikiwiki no ka hale kūʻai Corundum Pink Fused Alumina PFA Abrasive no ʻO ka Sandpaper a me ka huila Griding, "Hoʻololi no ka ʻoi aku ka nui!"ʻO kā mākou slogan, ʻo ia hoʻi, "Aia ka honua holoʻokoʻa i mua o mākou, no laila e aloha kāua!"E hoʻololi no kou ʻoi aku!Ua mākaukau ʻoe?
