Zvidhinha zveMullite & Zvidhinha zveSillimanite
Zvidhinha zvakawandaChidhinha chealuminium chinogadzirisa kupisa chakasimba chine mullite (3Al₂O₃·2SiO₂) sechikamu chikuru chekristaro, ndicho chega chinhu chakasimba chekristaro chinogadzirisa kupisa kwakanyanya muAl₂O₃-SiO₂ system. Chine kusimba kwakanyanya kwekupisa kwakanyanya (hapana deformation inopfuura 1600℃ yekushandisa kwenguva refu, ultra-low creep), kugona kwakanyanya kwekupisa (kuwedzera kupisa kwakaderera, kudzivirira kutsemuka/kubviswa kweganda), kuramba ngura kwakanyanya (kunodzivirira acidity/neutral slag scouring uye ngura yakanyunguduka, zvishoma.kusvibiswa), simba rekudzvanya-dzvanya remukamuri rakakwira uye kupenya kuri pakati nepakati, rine zvirevo zvakakwana uye kugadziriswa kunochinjika, rinoshanda zvakanyanya kumaindasitiri akasiyana-siyana anodziya zvakanyanya, zvichiita kuti ive chinhu chinoda kugadziriswa pakati pemaovheni akasiyana-siyana anodziya zvakanyanya.
Kurongwa Kwechigadzirwa:
1. Zvidhinha zveMullite Zvakagadzirwa neSintered:Yakagadzirwa nebauxite ne silica (1600-1700℃ sintering), Al₂O₃ 65%-72%. Inodhura zvishoma, yakakura, yakakodzera mamiriro ekunze anodziya nekupisa kwepamusoro-soro; inowanikwa muzvidhinha zvakajairwa/zvakagadzirwa zvakasiyana, zvinoshandiswa zvakanyanya muzvinhu zvekuvaka uye muzvitofu zvesimbi.
2. Zvidhinha zveMullite Zvakasanganiswa:Yakasanganiswa nemagetsi (inopfuura 1900℃), kristaro yakakora, chimiro chakasimba. Al₂O₃ 70%-75%, inodzivirira kupisa/ngura zvakanyanya, inotsvedza zvishoma. Yakakodzera mamiriro ekupisa kwakanyanya (inopfuura 1650℃) (magirazi anonyungudutsa, simbi yepamusoro).
3. Zvidhinha zveZircon Mullite:Chinowedzerwa muMullite + zircon (ZrSiO₄) (1650-1720℃ sintering). Al₂O₃ 68%-75%, ZrO₂ 8%-15%, chinodzivirira kukurwa kwevhu zvakanyanya. Chinoshandiswa muzvikamu zvegirazi zvinonyungudutsa uye muzvitofu zvinonyungudutsa zvisina ferrous zvine kukurwa kwakanyanya.
4. Zvidhinha zveMullite Zvakachena Kwazvo:Alumina/silica yakachena kwazvo, Fe₂O₃≤0.2%, Al₂O₃ 72%-78%, haipindi mvura inotonhora kupfuura 1850℃. Haina kusvibiswa, haipindi mvura inodziya zvakanyanya, inogona kushandiswa pakuchenesa kwakanyanya (simbi chaiyo, makilni esimbi emagetsi).
5. Zvikamu Zvakagadzirwa NeMullite:Yakagadzirwa zvichienderana nehukuru/chimiro chechoto, hapana kucheka panzvimbo yacho, kushanda zvakanaka pakuvaka, kuvhara zvakanaka. Yakakodzera zvikamu zvechoto zvisina kurongeka (zvitofu zvinopisa, machoto anotsemuka), zvichideredza njodzi yekudonha kwezvidhinha.
Zvidhinha zveSillimaniteYakagadzirwa kubva ku sillimanite yechisikigo (Al₂SiO₅, Al₂O₃ ine 62.9%) kuburikidza nekubatanidza, kugadzira uye kupisa kwakanyanya. Hunhu hwayo hukuru ndehwekuti sillimanite inoshanduka pakupisa kwakanyanya (1300-1500℃), pamwe nekuwedzera kwehuwandu hwepakati (2%-3%), izvo zvinogona kugadzirisa kuderera kwemuviri wezvidhinha, zvichiita kuti muviri wezvidhinha uve wakasimba uye wakavharwa zviri nani. Kusagadzikana kwayo kuri 1770-1830℃, iyo inonyanya kukodzera mamiriro ekushanda ari pakati nepakati nepamusoro ane kushanduka kukuru kwekushisa uye ngura yemakemikari, nekushanda kwakanaka kwemari.
Kurongwa Kwechigadzirwa:
1. Chidhinha cheSillimanite chakajairika:Sillimanite yechisikigo (Al₂O₃ 60%-62%) + bauxite/ivhu, inonhuhwirira. Inopinza zviri pakati nepakati, inopisa zvakanaka, inodhura zvishoma; yekupisa kwakanyanya uye kushanduka-shanduka kwekupisa kazhinji (kuputika kwehuro, fenicha yeceramic kiln).
2. Chidhinha cheSillimanite chakachena kwazvo:Sillimanite yechisikigo yakachena kwazvo (Al₂O₃ 62%-65%), Fe₂O₃≤0.3%, 1580-1650℃ inonyungudutsa. Yakasimba, inodzivirira ngura/alkali zviri nani; yengura makemikari mashoma (makilni egirazi, maovheni ekunyungudutsa asina ferrous).
3. Sillimanite-Mullite Composite Brick:Sillimanite + mullite, inodzikisira ganda pakuchinja kwechikamu + kugadzikana pakupisa kwakanyanya. Al₂O₃ 63%-68%, inodzivirira kupisa nekudzikama; kune tembiricha yakakura, inotakura mutoro pakupisa kwakanyanya (pasi pefurnace, girazi rinoyerera).
Zvigadzirwa zveSillimanite zvidhinha:Chidhinha chemugero, mugero wekuyerera kwemvura, pombi inotenderera, dhishi rekudyisa, rin'i yegomba, padhishi rekusvudzira, punchi, sirinda yekudyisa, dhishi reslag remoto, dhishi redamper, dhishi rearch, chivharo chedhishi rekudyisa, dhishi rinopinda nepaburi, dhishi reburner, danda, dhishi rekudyisa nedzimwe mhando netsanangudzo.
Zvakanakira Zvikuru:
1. Kuzviwedzera Kwemuviri Pakuchinja Kwechikamu:Kuwedzera kwekupisa kwakanyanya kunodzivisa shrinkage, zvichiita kuti zvive nyore kuomerera uye kuvharwa zvakanaka.
2. Kugadzikana Kwekupisa Kwakaringana:Kukura kwekupisa kushoma, kudzivirira kupisa kunopisa/kupwanyika zvakanaka, zvakakodzera kushanduka-chinja kwekupisa nguva nenguva.
3. Kubudirira Kwazvo Pamutengo:Zvinhu zvechisikigo zve sillimanite, zvinodhura zvishoma pane zvidhinha zve mullite, zvakakodzera kushandiswa mumamiriro ezvinhu anonyanya kudhura.
4. Kuramba Kwakanaka Kwetsvina:Haipindi ngura yetsvina/girazi uye haiparare zvakanyanya, uye haisi nyore kubvisa.
5. Zvisikwa Uye Zvine Hushamwari Nezvakatipoteredza:Hapana tsvina inokuvadza, kusvibiswa kwezvinhu zvishoma, zvakakodzera maovheni asingakuvadzi nharaunda.
