Zotsutsa
lingaliro:
Kalasi yazinthu zopanda zitsulo zopanda zitsulo zokhala ndi refractoriness zosachepera 1580 ° C.Refractoriness imatanthawuza kutentha kwa Celsius komwe chitsanzo cha refractory cone chimatsutsana ndi kutentha kwakukulu popanda kufewetsa ndi kusungunuka popanda katundu.Komabe, kutanthauzira kokha kwa refractoriness sikungathe kufotokozera mokwanira zipangizo zokanira, ndipo 1580 ° C siili mtheradi.Tsopano zimatanthauzidwa ngati zipangizo zonse zomwe thupi ndi mankhwala zimalola kuti zigwiritsidwe ntchito kumalo otentha kwambiri zimatchedwa zipangizo zotsutsa.Zipangizo zotsutsa zimagwiritsidwa ntchito kwambiri muzitsulo, makampani opanga mankhwala, mafuta, kupanga makina, silicate, mphamvu ndi mafakitale ena.Iwo ndi aakulu kwambiri mumakampani opanga zitsulo, omwe amawerengera 50% mpaka 60% ya chiwerengero chonse.
zotsatira:
Zipangizo zotsutsa zimagwiritsidwa ntchito m'magawo osiyanasiyana azachuma cha dziko monga zitsulo, zitsulo zopanda chitsulo, galasi, simenti, zoumba, petrochemicals, makina, boilers, makampani kuwala, mphamvu zamagetsi, makampani ankhondo, etc., ndipo ndi zofunika zofunika zipangizo kuonetsetsa ntchito yopanga ndi chitukuko cha zamakono za mafakitale pamwamba.Zimagwira ntchito yofunika komanso yosasinthika pakukula kwa mafakitale omwe amatentha kwambiri.
Kuyambira 2001, motsogozedwa ndi kukula kwachangu kwa mafakitale omwe amatentha kwambiri monga chitsulo ndi chitsulo, zitsulo zopanda chitsulo, mafuta a petrochemicals, ndi zida zomangira, makampani okanira akhala akukula bwino ndipo akhala wopanga wamkulu komanso wogulitsa kunja kwa zinthu zotsutsana ndi zomanga. dziko.Mu 2011, kupanga ku China kudakhala pafupifupi 65% yapadziko lonse lapansi, ndipo kuchuluka kwake komanso kugulitsa kwake kudakhala koyamba padziko lapansi.
Kukula kwa mafakitale okana kumagwirizana kwambiri ndi kusungidwa kwa migodi yapakhomo.Bauxite, magnesite ndi graphite ndi zinthu zitatu zazikulu zokana.Dziko la China ndi limodzi mwa mayiko atatu amene ali padziko lonse lapansi amene amagulitsa mankhwala a bauxite, omwe ali ndi maginito akuluakulu padziko lonse, ndiponso ndi amene amatumiza graphite kunja.Zida zolemera zathandizira zida za China zokana kwazaka khumi zachitukuko chofulumira.
Ndi nthawi ya "Mapulani a Zaka khumi ndi ziwiri", China ikufulumizitsa kuthetsa mphamvu zopangira mphamvu zomwe zimagwiritsidwa ntchito kale komanso zowononga mphamvu zambiri.Makampaniwa adzayang'ana pa chitukuko ndi kulimbikitsa ng'anjo zatsopano zopulumutsira mphamvu, chitukuko cha njira zamakono zopulumutsira mphamvu, kasamalidwe ka mphamvu, kuwongolera mpweya wa "zinyalala zitatu" ndi kugwiritsa ntchito zinthu za "zinyalala zitatu" Kubwezeretsanso, ndi zina zotero. kubwezereranso ndi kugwiritsanso ntchito zida zomangira zitagwiritsidwa ntchito, kuchepetsa kutulutsa zinyalala zolimba, kupititsa patsogolo kagwiritsidwe ntchito kazinthu zonse, ndikulimbikitsa mokwanira kasungidwe ka mphamvu ndi kuchepetsa utsi.
The "Refractory Industry Development Policy" ikunena kuti kugwiritsidwa ntchito kwa unit of refractory materials mumakampani azitsulo aku China ndi pafupifupi ma kilogalamu 25 pa tani yachitsulo, ndipo kugwera pansi pa kilogalamu 15 pofika chaka cha 2020. , yowongola mphamvu kwambiri, yopanda kuipitsa, komanso yogwira ntchito.Zogulitsa zidzakwaniritsa zosowa za chitukuko cha dziko monga zitsulo, zomangira, mankhwala, ndi mafakitale omwe akubwera, ndipo zidzawonjezera luso lazogulitsa kunja.
Zida zokanira zili ndi mitundu yambiri komanso ntchito zosiyanasiyana.Ndikofunikira kugawa mwasayansi zida zotsutsa kuti zithandizire kafukufuku wasayansi, kusankha mwanzeru komanso kasamalidwe.Pali njira zambiri zogawira zida zokanira, kuphatikiza magulu amtundu wamankhwala, gulu lamankhwala amchere amchere, gulu lakapangidwe kazinthu, komanso gulu la zinthu zakuthupi.
Gulu:
1.Malinga ndi kuchuluka kwa refractoriness:
Wamba refractory zakuthupi: 1580 ℃ ~ 1770 ℃, zapamwamba refractory zakuthupi: 1770 ℃ ~ 2000 ℃, wapadera kalasi refractory zakuthupi: > 2000 ℃
2. Zinthu zokanira zitha kugawidwa m'magulu awiri:
Zinthu zowotchedwa, zopangira zopanda ntchito, zokanira zopanda mawonekedwe
3. Zosankhidwa ndi zinthu zakuthupi:
Acid refractory, neutral refractory, alkaline refractory
4. Gulu molingana ndi kapangidwe kake ka mineral
Izi gulu njira akhoza mwachindunji yodziwika zikuchokera ndi makhalidwe a zipangizo zosiyanasiyana refractory.Ndi njira yodziwika bwino pakupanga, kugwiritsa ntchito, ndi kafukufuku wasayansi, ndipo ili ndi tanthauzo lamphamvu logwiritsa ntchito.
Silika (silika), aluminium silicate, corundum, magnesia, magnesia calcium, aluminium magnesia, magnesia silicon, carbon composite refractories, zirconium refractories, refractories yapadera
6. Gulu la zinthu zosaoneka bwino zokanira (zogawidwa molingana ndi njira yogwiritsira ntchito)
Zoyikapo, zokutira zopopera, zida za ramming, mapulasitiki, zogwirizira, zida zowonera, zida zopaka, zowuma zowuma, zotayira zokha, zotayirira.
Osalowerera ndale amapangidwa makamaka ndi aluminiyamu, chromium okusayidi kapena kaboni.Chogulitsa cha corundum chokhala ndi aluminiyamu yopitilira 95% ndi zinthu zokanira zapamwamba kwambiri zomwe zimagwiritsidwa ntchito mosiyanasiyana.
Chiping Wanyu Industry and Trade Co., Ltd., yomwe idakhazikitsidwa mu 2010, imagwira ntchito yopanga zinthu zosagwira komanso zosagwira ntchito: mchenga wagawo loyera la corundum, ufa wabwino, ndi zinthu zingapo zamchenga za granular.
8-5#, 5-3#, 3-1#, 3-6#, 1-0#, 100-0#, 200-0#, 325-0#
Mchenga wa granular: 20 #, 24 #, 36 #, 40 #, 46 #, 54 #, 60 #, 80 #, 100 #, 150 #, 180 #, 200 #, 220 #, 240 #,
