    Hana ʻia nā pōhaku lepo alumina kūikawā o ka sillimanite kiʻekiʻe, pyrite, mullite, a me corundum e like me nā mea maka, a he 1750 ~ 1790 ka mea hoʻomau. Ma waena o lākou, kiʻekiʻe ka Al2O3, a liʻiliʻi ka nui o nā impurities, a liʻiliʻi ka hoʻokumu ʻana o ke aniani fusible. No laila, ʻoi aku ka kiʻekiʻe o ka mahana o ka palupalu ma mua o nā pōhaku lepo. Loaʻa i nā pōhaku alumina kūikawā he nui aku Al2O3, kahi kokoke i nā mea pale pale kūlike ʻole a hiki ke pale aku i ka lū o ka slag acid a me ka slag alkaline.

  • High Alumina brick

    ʻO brick brick kiʻekiʻe

    ʻO nā pōhaku alumina kiʻekiʻe kahi alumina silicate refractory material, kahi i ʻoi aku ai ka nui o nā mea alumina i ka 55%, a ua helu ʻia ia mai nā mea kiʻekiʻe o nā alumina. He kiʻekiʻe wela ia'ku a me ke kiʻekiʻe wela e kū'ē'ē mai ma 1770 ° C a ma luna. ʻO nā pōhaku alumina kiʻekiʻe he kūpaʻa slag maikaʻi a hoʻohana nui ʻia no ka masonry o nā umu uila e hana ana i ke kila, nā umu aniani, nā kapuahi hoʻokaʻa sima, a pēlā aku.

  • Fireclay Brick

    ʻO Fireclay Brick

    Hana ʻia nā pōhaku uila Fireclay e 50% pālolo palolo a me 50% pālolo pālolo paʻakikī, i ʻōpala ʻia e like me kekahi mau koi nui o ka ʻāpana. Ma hope o ka hoʻoheheʻe ʻana a me ka hoʻomaloʻo ʻana, puhi ʻia lākou i kahi mahana kiʻekiʻe o 13001400. ʻO nā mea pōhaku Fireclay nāwaliwali waikawa refactory huahana, i hiki ke kūpale i ke erosion o ka acidic slag a me ka acid acid, a loaʻa i kahi palupalu e kūʻē i nā alkaline mea, maikaʻi mehana hana, a me ke kūpale ʻana i ke anuanu wikiwiki a me ka wela.

    ʻO nā bricks Fireclay kekahi o nā ʻano nui o nā huahana silica-alumina series. ʻO lākou nā huahana refactory me 30-48% Al2O3 ʻike i hana ʻia i ka clinker pālolo e like me ka hoʻopili a me ka palolo paʻa e like me ka mea hoʻopaʻa.

  • Corundum Brick

    ʻO Corundum Brick

    ʻO ka ʻike alumina o ka brick corundum ma mua o 90% a ʻo ka pae nui aniani he corundum. Loaʻa iā ia ka ikaika compressive kiʻekiʻe ma ka mahana o ka lumi (a i 340MPa), ke kaumaha o ka hoʻoulu ʻana i ke ana wela (ʻoi aku ma mua o 1700 ℃), kūpaʻa kemika maikaʻi, a me ke kūpaʻa ikaika i ka slag acidic a alkaline, metala a me ke aniani hoʻoheheʻe ʻia, a me nā mea ʻē aʻe.
    Pili ke kūpaʻa haʻalulu wela i kona ʻano, a maikaʻi ke kūpaʻa o ka huahana kūpilikiʻi. Aia he ʻelua mau ʻano o nā brick brund i kuni ʻia a me nā pōhaku corundum fused. Hiki ke hoʻohana ʻia ʻo alumina i kuhi ʻia a me fund corundum e like me nā mea maka, a i ʻole ʻo bauxite clinker me ke kiʻina Al2O3 / SiO2 kiʻekiʻe hiki ke hoʻohui ʻia me ka alumina i kuhi ʻia a hana ʻia e ke ʻano sinter. Hiki ke hoʻohana ʻia ka waikawa phosphoric a i ʻole nā ​​mea hoʻopaʻa hoʻopili ʻē aʻe e hana i nā pōhaku lepo kī ʻole ʻia

  • Silica Brick

    ʻO Silica Brick

    ʻO ka silica brick kahi mea kūpilikiʻi acidic me ka pale maikaʻi i ka ʻaʻai slag acid. ʻO ka mahana palupalu o ka brick silica ma lalo o ka ukana he 1640 ~ 1670 ° C ka nui, kūpaʻa ka leo i ka mahana kiʻekiʻe, a hiki ke hoʻohana ʻia no kahi manawa lōʻihi.

    Kahi acidic refractory material ʻano nui i haku ʻia o tridymite, cristobalite a me kahi liʻiliʻi o ke koena quartz a me ke aniani pae. ʻO ka ʻikepili dioxide silikone ma luna o 94%, ʻo ka paʻa maoli he 2.35g / cm3, he kūpaʻa ia i ka loli acid acid a me ka kiʻekiʻe wela o ka wela. ʻAʻole ia e deform ma hope o ka hoʻohana lōʻihi ma ke ana wela. ʻO ke kūpaʻa haʻalulu haʻahaʻa (1 ~ 4 mau manawa o ka hoʻololi wela i ka wai) hoʻohana ʻia ka silica kūlohelohe e like me nā mea maka, a hoʻohui ʻia kahi nui kūpono o ka mineralizer e hāpai i ka hoʻohuli ʻana o ka quartz i ke kino i tridymite. Puhi mālie i ka 1350 ~ 1430 ℃ ma lalo o ka ʻemi o ka lewa. Ke hoʻomehana ʻia i 1450 ℃, aia ma kahi o 1.5 ~ 2.2% o ka hoʻonui nui ʻana o ka leo. ʻO kēia koena hoʻonui ʻana e hoʻopili i nā hono ʻoki a hōʻoia i ka paʻa ʻana o ka ea i ka masonry a me ka ikaika o ke ʻano.
