Silicon Carbide Castable: Yankho Labwino Kwambiri la Kugwiritsa Ntchito Zotentha Kwambiri & Zosavala

Mu mafakitale, kutentha kwambiri, kuwonongeka kwa makina, ndi kuwonongeka kwa mankhwala ndi adani akuluakulu a moyo wa ntchito ya zida ndi magwiridwe antchito a zida. Kaya ndi ng'anjo yachitsulo, uvuni wozungulira wa simenti, kapena chotengera cha mankhwala, magwiridwe antchito a zinthu zotsutsana ndi zomwe zimapangitsa kuti mzere wopangira ukhale wolimba. Pakati pa zinthu zambiri zotsutsana ndi zinthu,silicon carbide yotayidwaImadziwika bwino chifukwa cha kukana kutentha kwambiri, kukana kukalamba, komanso kukana dzimbiri, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri m'mafakitale osiyanasiyana omwe amafunidwa kwambiri padziko lonse lapansi.

Chotsukira cha silicon carbide ndi mtundu wa zinthu zosaoneka ngati zotsukira zopangidwa ndi silicon carbide (SiC) yoyera kwambiri ngati chinthu chachikulu, chophatikizidwa ndi zomangira zapamwamba, zowonjezera, ndi madzi. Chili ndi mawonekedwe osavuta kumanga (chingathe kutsanulidwa, kutsukidwa, kapena kugwedezeka kukhala mawonekedwe), chosinthika kwambiri kuzinthu zovuta, ndipo chimatha kupanga chingwe cholimba komanso chofanana pambuyo pochikonza ndi kuwotcha. Poyerekeza ndi njerwa zachikhalidwe zotsukira ndi zinthu zina zotsukira, chili ndi ubwino woonekeratu wa magwiridwe antchito, zomwe zimatha kuthetsa mavuto a nthawi yochepa yogwira ntchito komanso kukonza pafupipafupi zingwe za zida m'malo ovuta.

Magawo Ofunika Kwambiri Ogwiritsira Ntchito a Silicon Carbide Castable

1. Makampani Opanga Zitsulo: Mwala Wapangodya wa Kusungunula Zinthu Pakutentha Kwambiri

Makampani opanga zitsulo ndi amodzi mwa misika yayikulu kwambiri yogwiritsira ntchito silicon carbide castable. Mu ng'anjo zophulika, ma converter, ma arc furnaces amagetsi, ndi ma fyuni osungunulira zitsulo osapanga ferrous (monga aluminiyamu, mkuwa, ndi zinc smelting), ma linings amakumana ndi zovuta kwambiri monga kutentha kwambiri (mpaka 1600℃), kukokoloka kwa chitsulo chosungunuka, ndi slag scouring ya ng'anjo. Silicon carbide castable, yokhala ndi malo ake osungunuka kwambiri (oposa 2700℃) komanso kukana bwino kuwonongeka, imagwiritsidwa ntchito kwambiri mu lining ya milomo ya ng'anjo, ma tapholes, malo otulutsira slag, ndi zigawo zina zofunika. Imatha kukana kuwonongeka kwa chitsulo chosungunuka, chitsulo, ndi zitsulo zopanda ferrous, kuchepetsa kuchuluka kwa lining replacement, ndikuwonjezera nthawi yogwira ntchito ya ng'anjo. Mwachitsanzo, mu ng'anjo zosungunulira aluminiyamu, silicon carbide castable imagwiritsidwa ntchito pa lining ya dziwe losungunulira, lomwe limatha kupirira dzimbiri la aluminiyamu wosungunuka ndikuwonjezera moyo wa ng'anjo ndi 50% poyerekeza ndi zipangizo zachikhalidwe.

2. Makampani Opanga Zipangizo Zomangira: Kukulitsa Kugwiritsa Ntchito Bwino kwa Simenti ndi Kupanga Zinthu Zomangira

Mu makampani opanga zipangizo zomangira, ma uvuni ozungulira simenti, ma uvuni ozungulira a ceramic, ndi ma uvuni osungunula magalasi ali ndi zofunikira kwambiri pa zipangizo zotsutsa. Chotenthetsera chisanadze, cholekanitsa mphepo, ndi njira yopumira mpweya ya ma uvuni ozungulira a simenti amakhala pamalo otentha kwambiri, fumbi, komanso okokoloka kwa mpweya kwa nthawi yayitali. Kugwiritsa ntchito silicon carbide castable ngati lining sikungoletsa kusintha kwa kutentha kwambiri komanso kumateteza bwino kukanda ndi kusweka kwa simenti clinker ndi fumbi. Izi zimachepetsa ndalama zosamalira makina a uvuni ndikuwonjezera mphamvu yopangira simenti. Mu ma uvuni ozungulira a ceramic, silicon carbide castable imagwiritsidwa ntchito pa lining ya gawo lotentha kwambiri, lomwe limatha kusintha kutentha mwachangu panthawi yowotcha ceramic ndikuwonetsetsa kuti kutentha kwa uvuni kuli kokhazikika, motero kukweza mtundu wa zinthu za ceramic.

3. Makampani Opanga Mankhwala: Kukana Kudzimbirika M'malo Ovuta Kwambiri

Makampani opanga mankhwala amagwiritsa ntchito zinthu zosiyanasiyana zowononga (monga ma acid, alkali, ndi mchere) komanso njira zochitira zinthu zotentha kwambiri. Zipangizo monga ma kettle otenthetsera kutentha kwambiri, zotenthetsera mankhwala, ndi makina ochotsera mpweya wa flue ndizofunikira kwambiri pa kukana dzimbiri kwa zinthu zotsutsa dzimbiri. Silicon carbide castable ili ndi kukhazikika kwabwino kwa mankhwala ndipo imatha kukana kuwonongeka kwa ma acid ambiri amphamvu, alkali, ndi zosungunulira zachilengedwe. Imagwiritsidwa ntchito kwambiri m'mitsempha ya zotengera zochitira mankhwala, mitsinje ya flue, ndi mitsempha ya chimney. Mwachitsanzo, m'malo opangira magetsi otenthetsera zinyalala, mpweya wa flue uli ndi mitundu yosiyanasiyana ya mpweya wowononga ndi tinthu tating'onoting'ono. Kugwiritsa ntchito silicon carbide castable pamitsempha ya flue kumatha kuletsa dzimbiri ndi kuwonongeka, kuonetsetsa kuti njira yochizira mpweya wa flue ikugwira ntchito bwino komanso mokhazikika.

4. Makampani Opanga Mphamvu: Kuthandizira Kugwiritsa Ntchito Zipangizo Zamagetsi Moyenera

Mu makampani opanga mphamvu, malo opangira magetsi otentha, malo opangira magetsi a biomass, ndi malo opangira magetsi otayira zinyalala zonse zimafunikira zinthu zoyeretsera kuti zitsimikizire kuti zipangizo zikugwira ntchito bwino. Khoma la madzi a boiler, superheater, ndi economizer ya malo opangira magetsi otentha zimaphwanyidwa ndi mpweya wotentha kwambiri komanso kuphwanyidwa kwa phulusa. Silicon carbide castable imagwiritsidwa ntchito ngati chotchingira choletsa kusweka kwa zigawo izi, zomwe zimatha kuchepetsa kusweka kwa khoma la chubu cha boiler ndikuwonjezera moyo wa ntchito ya boiler. Mu malo opangira magetsi a biomass, chifukwa cha kuchuluka kwa zitsulo za alkali mu mafuta a biomass, chotchingira cha ng'anjo chimaphwanyidwa mosavuta. Silicon carbide castable imatha kukana bwino dzimbiri lachitsulo cha alkali, ndikutsimikizira kuti ng'anjoyo ikugwira ntchito bwino kwa nthawi yayitali.
