ʻO ka silica refractory brick he waika refractory a he maikaʻi ke kūpaʻa ʻana o ka waika slag erosion. ʻO ka refractoriness ʻo Slica bricks ma lalo o ka ukana a hiki i 1640 ~ 1690 ℃, ʻike ʻia ka mahana palupalu mua o 1620 ~ 1670 ℃ a ʻo ka nui maoli ka 2.35g/cm3. Hiki ke lawelawe ʻo Silicon fire brick i ka wela kiʻekiʻe no ka wā lōʻihi a mālama i ka paʻa o ka leo me ka ʻole o ka loli. Loaʻa i ka 94% ʻo SiO2 ka ʻikepili reractory silikon. ʻOi aku ka ikaika o ka wela kiʻekiʻe a me ke kūpaʻa haʻahaʻa haʻahaʻa haʻahaʻa. Hana ʻia nā pōhaku ahi silicate me ka ʻaila silica maoli e like me ka mea maka, hoʻohui ʻia ka mineralizer kūpono e hāpai 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 hoʻohaʻahaʻa ʻana i ka lewa. Ke wela a hiki i 1450 ℃, aia nā helu 1.5 ~ 2.2% o ka hoʻonui nui o ka leo. ʻO kēia ma hope o ka hoʻonui ʻana e hoʻopaʻa ʻia ka ʻoki hui ʻana a hōʻoia i ka mālama ʻana i ka ea impermeability maikaʻi a me ka ikaika o ka hale.

Na waiwai o ka Brick Silica Ahi

• ʻO ke kūpaʻa maikaʻi o ka waika erosion,
• ikaika wela kiʻekiʻe,
• Kiʻekiʻe refractoriness: 1690 ~ 1710 ° C,
• RUL kiʻekiʻe: ma kahi o 1620-1670 ℃,
• Paʻa leo ma ka wela kiʻekiʻe,
• Kūleʻa haʻalulu wela maikaʻi.

Huipuia o Silica Ahi Brick

ʻO ka pahu ahi silikoni he brick refractory i ʻoi aku ka nui o ka silica ma mua o 93%, 50% -80% o tridymite, 10% -30% o ka cristobalite, quartz a me ka māhele aniani, ma kahi o 5% -15%. ʻO ka hui mineralogical o ka silicate brick ka nui o ka quartz a me ka quartz, a me kahi liʻiliʻi o ka quartz a me ka vitreous. ʻO ka quartz unahi, ka quartzite quartz a me ke koena quartz hoʻololi nui i ka leo ma muli o ka hoʻololi ʻana o ke ʻano aniani i ka haʻahaʻa haʻahaʻa, no laila ʻilihune ka paʻa wela o ka silicate refractory brick i ka wela haʻahaʻa. I ke kaʻina hana, ma lalo o 800 ℃ e hoʻolōʻihi i ka hoʻomehana a me ka hoʻoluʻu, i pale aku ai i nā māwae. No laila ʻaʻole pono ma lalo o 800 ℃ nā lele wela o ke kiln.

Ke Kaʻina Hana Hana Pilika Ahi

Hana ʻia nā pōhaku ahi silicate mai ka quartzite me kahi mea liʻiliʻi o ka mineralizing agent. Ke puhi ʻia i ka wela kiʻekiʻe, ʻo ka silica refractory bricks mineral composition i haku ʻia me ka quartz unahi, ka quartzite quartz, ke aniani a me nā mea paʻakikī ʻē aʻe i hana ʻia ma ke kiʻekiʻe wela, a ʻoi aku ka nui o AiO2 ma mua o 93%. Ma waena o nā pōhaku silica maikaʻi loa, ʻo ka ʻike o ka quartz scale ka mea kiʻekiʻe loa, ʻo 50% ~ 80%. ʻO cristobalit ka mea aʻe, he 10% a 30% wale nō. Hoʻololi nā mea o ka quartz a me ke aniani ma waena o 5% a me 15%
