Kina Nā mea hoʻoheheʻe pōhaku silica pale ahi maikaʻi loa mai ka hale hana kūʻai hale hana a me nā mea hana | Rongsheng

He kūpaʻa ʻakika ka piliki pale ʻakika a he kūpaʻa maikaʻi kona i ka ʻino ʻana o ka ʻōpala waikawa. ʻO ka kūpaʻa o nā piliki Slica ma lalo o ke kaumaha a hiki i ka 1640 ~ 1690 ℃, ʻo ka mahana palupalu mua he 1620 ~ 1670 ℃ a ʻo ka nui maoli he 2.35g / cm3. Hiki i ka piliki ahi Silicon ke lawelawe i ka mahana kiʻekiʻe no ka manawa lōʻihi a mālama i ka paʻa o ka leo me ka ʻole o ka hoʻololi ʻana. Loaʻa i ka piliki pale ʻakika Silicon ma mua o 94% SiO2. Loaʻa i ka piliki silicate ka ikaika wela kiʻekiʻe a me ke kūpaʻa haʻalulu wela haʻahaʻa. Hana ʻia ka piliki ahi silicate me ka silica ore maoli ma ke ʻano he mea maka, hoʻohui ʻia ka mineralizer kūpono e hoʻolaha i ka quartz i loko o ke kino ʻōmaʻomaʻo i hoʻololi ʻia i tridymite a puhi mālie ʻia ma o ka mahana o 1350 ~ 1430 ℃ i ka lewa hoʻemi. Ke hoʻomehana ʻia a hiki i ka 1450 ℃, aia he 1.5 ~ 2.2% o ka hoʻonui ʻana o ka leo holoʻokoʻa. ʻO kēia hoʻonui ma hope o ka hoʻonui ʻana e hoʻopaʻa i ka ʻoki hui a hōʻoia i ka mālama ʻana o ke kūkulu ʻana i kahi impermeability maikaʻi o ka ea a me ka ikaika o ke kūkulu ʻana.

Nā Waiwai o nā Piliki Ahi Silica

• Kū'ē maika'i i ka ʻānai ʻakika,
• Ikaika wela kiʻekiʻe,
• Ka paʻakikī kiʻekiʻe: 1690 ~ 1710°C,
• RUL kiʻekiʻe: ma kahi o 1620-1670 ℃,
• Paʻa ka leo ma ke ana wela kiʻekiʻe,
• Kū'ē maika'i i ka ha'alulu wela.

Ka Hoʻokumu ʻana o ka Piliki Ahi Silica

ʻO ka poloka ahi Silicon kahi piliki refractory nona ka nui o ka silica ma mua o 93%, 50%-80% o tridymite, 10%-30% o cristobalite, quartz a me ke aniani, ma kahi o 5%-15%. ʻO ka haku mele mineralogical o ka piliki silicate he quartz unahi a me ka quartz, a me kahi liʻiliʻi o ka quartz a me ka vitreous. ʻO ka quartz unahi, quartzite quartz a me ke koena quartz e loli nui i ka nui ma muli o ka loli o ke ʻano kristal i ka mahana haʻahaʻa, no laila ʻaʻole maikaʻi ke kūpaʻa wela o ka piliki refractory silicate i ka mahana haʻahaʻa. I ke kaʻina hana hoʻohana, ma lalo o 800 ℃ e lohi ka hoʻomehana a me ka hoʻomaʻalili ʻana, i mea e pale ai i nā māwae. No laila, ʻaʻole pono e lele ma lalo o 800 ℃ o ka umu.

Kaʻina Hana Hana Piliki Ahi Silica

Hana ʻia nā piliki ahi silicate mai ka quartzite me kahi liʻiliʻi o ka mea mineralizing. Ke puhi ʻia i ka mahana kiʻekiʻe, ua haku ʻia ka hui mineral o nā piliki refractory silica me ka quartz unahi, ka quartzite quartz, ke aniani a me nā ʻiʻo pae paʻakikī ʻē aʻe i hoʻokumu ʻia i ka mahana kiʻekiʻe, a ʻoi aku ka nui o ka AiO2 ma mua o 93%. Ma waena o nā piliki silica i puhi ʻia me ka maikaʻi, ʻo ka nui o ka quartz unahi ka mea kiʻekiʻe loa, e helu ana no 50% ~ 80%. ʻO cristobalit ka mea aʻe, e helu ana no 10% a 30% wale nō. ʻO ka nui o ka quartz a me ke aniani e loli ma waena o 5% a me 15%.

Ka hoʻohana ʻana o ka pōhaku ahi Silica

Hoʻohana nui ʻia nā piliki ahi silica ma ke ʻano he mea kūpaʻa no ka paia pale o ke keʻena coking a me ke kapuahi i loko o ka umu coke, ke keʻena regenerative a me ka ʻeke slag i loko o ka umu kapuahi hāmama kila, ka umu lua hoʻomoʻa a me ka umu hoʻoheheʻe aniani, a me nā wahi kaumaha ʻē aʻe a me luna i loko o ka umu ahi keramika. Hiki ke hoʻohana ʻia nā piliki silicate no ka wahi kaumaha i ke kiʻekiʻe o ka mahana a me luna o ka umu kapuahi hāmama waikawa.
