Hauv kev lag luam chaw uas kub siab, siab, thiab hnav cov khoom sib tw, cov kev daws teeb meem txhim khu kev qha yog qhov tseem ceeb.Sillimanite cibsawv tawm raws li "tus neeg ua haujlwm hauv kev lag luam," nrog cov khoom tshwj xeeb uas txhawb nqa kev ua haujlwm, txiav nqi, thiab txhim kho cov khoom zoo thoob plaws metallurgy, ceramics, thiab iav manufacturing. Ntawm no yog vim li cas lawv thiaj yog qhov kev xaiv zoo tshaj plaws thoob ntiaj teb.
1. Core Properties: Dab tsi Ua rau Sillimanite Cib Yuav Tsum Tau
Muab los ntawm aluminosilicate ntxhia sillimanite, cov cib no muab peb qhov zoo tshaj plaws:
Ultra-High Refractoriness:Nrog lub melting point tshaj 1800 ° C, lawv tiv taus kub heev (tseem ceeb rau hlau smelting thiab iav melting, qhov twg temps tshaj 1500 ° C) tsis muaj warping los yog degrading.
Tsawg Thermal Expansion:Tus nqi qis dua 1% ntawm 1000 ° C tiv thaiv kev tawg ntawm thermal poob siab, ua kom muaj kev ruaj khov nyob rau hauv cov cua kub cua txias-txias ib puag ncig xws li blast furnaces.
Superior Resistance:Nthav thiab nyuaj, lawv tiv thaiv kev puas tsuaj los ntawm Molten cov hlau / slag thiab tshuaj yaig thiab yuam sij rau kev ua yeeb yam thiab metallurgy.
Cov yam ntxwv no tig sillimanite cib los ntawm "zoo-rau-muaj" mus rau "yuav tsum muaj" rau kev ua haujlwm zoo.
2. Metallurgy: Txhim kho hlau & hlau ntau lawm
Kev lag luam metallurgical cia siab ntau rau sillimanite cib rau cov cuab yeej siv cua sov:
Blast Furnace Linings:Nyob rau hauv lub "kub cheeb tsam" (1500-1600 ° C) ntawm cov hlau-ua rauv, lawv outperform tsoos firebricks. Ib tsob ntoo Indian steel pom 30% ntev dua rau qhov cub thiab 25% txo tus nqi kho tom qab hloov.
Tundish & Ladle Linings:Txo cov hlau sib kis thiab txuas ntxiv lub neej ntawm li 40% (raws li ib tug European steelmaker), lawv ua kom smoother molten steel tuav.
Desulfurization nkoj:Lawv tsis kam mus rau sulfur-nplua nuj slag tswj kev sib xws, pab ua tau raws li cov qauv purity nruj
Rau metallurgists, sillimanite cib yog ib qho kev nqis peev zoo hauv kev tsim khoom
3. Ceramics: Boosting Vuas, Sanitary Ware & Technical Ceramics
Hauv ceramics, sillimanite cib ua haujlwm ob lub luag haujlwm tseem ceeb:
Kiln Linings:Kev tuav cov cua sov sib xws (txog 1200 ° C) hauv kev tua hluav taws, lawv qhov qis qis tiv thaiv kev puas tsuaj. Tus tsim cov pobzeb Suav txiav cov nqi hluav taws xob los ntawm 10% tom qab rov ua dua, nrog 15-20% qis dua tag nrho siv zog.
Raw Material Additive:Hauv av rau hauv cov hmoov (5-10% hauv kev sib xyaw), lawv txhawb cov neeg kho tshuab lub zog (25% siab dua flexural zog) thiab thermal stability (30% tsawg thermal shock puas) hauv cov txheej txheem ceramics.
4. Glass Manufacturing: Sib npaug zoo & nqicov
Sillimanite bricks daws teeb meem iav ntau lawm:
Kiln Regenerators:Nyob rau hauv lub tshav kub-capturing regenerators, lawv tiv thaiv tawg thiab iav vapor nkag. Ib lub chaw tsim khoom hauv North American pom 2-xyoo lub neej cib ntev dua, txiav cov nqi hloov pauv los ntawm $ 150,000 rau ib lub kiln.
Tshwj xeeb iav:Nrog qis dua 0.5% hlau oxide, lawv tsis txhob kis cov iav kho qhov muag lossis borosilicate iav, ua kom pom tseeb thiab ruaj ntseg tshuaj rau labware lossis smartphone cov ntxaij vab tshaus.
5. Tshuaj & Lwm Cov Kev Lag Luam: Kev Kho Hniav
Kev Siv Tshuaj:Cov txheej txheem kub kub reactors, lawv tiv thaiv kom tsis txhob xau thiab txuas ntxiv lub neej ntawm cov cuab yeej siv - qhov tseem ceeb rau kev nyab xeeb hauv cov chiv, petrochemical, lossis kev tsim tshuaj.
Waste Incineration:Resisting 1200 ° C kub thiab pov tseg puas, lawv txo kev txij nkawm ntawm cov nroj tsuag pov tseg-rau-zog.
Xaiv Sillimanite Bricks rau kev vam meej mus ntev
Txawm hais tias koj yog tus tsim steel, tus tsim khoom siv ceramic, lossis cov chaw tsim khoom iav, sillimanite cib xa cov txiaj ntsig. Lawv qhov tshwj xeeb sib xyaw ntawm refractoriness, tsis tshua muaj kev nthuav dav, thiab kev ua haujlwm ua rau lawv muaj txiaj ntsig zoo, ntau yam kev daws teeb meem.
