Kodi ndi zinthu ziti zomwe zili ndi zida?

Zipangizo zotsitsimutsidwa ndi zida zothandizira zomwe zimagwiritsidwa ntchito popanga zitsulo zopangira kuti zitetezeke ndi kukokoloka kwa chitsulo chamoto chamoto chamadzi komanso slag. Monga chidebe chachikulu chogwirizira ndikunyamula chitsulo (kuchokera ku Converter / ming'alu yamagetsi kuti ikhale yosasunthika) Otsatirawa ndi zigawo zazikulu, zofunika kuchita komanso zovuta za ukadaulo zomwe zimachitikadi:

Kodi zida zotsimikizika zomwe zili?

Zipangizo zodzitchinjiriza zimapangidwa makamaka ndi zotupa zadothi ndi zogwirira ntchito zogwirizira. Zipangizo zake zamkati zimafunikira kuthana ndi zinthu zowopsa monga kukwapula, kukokoloka kwamankhwala ndi kugwedezeka kwamafuta ofunda kwambiri.

Zingwe zopitilira muyeso nthawi zambiri zimagawika m'magawo otsatirawa malinga ndi madera osiyanasiyana omwe amalumikizana ndi zitsulo zosungunula ndi zofunikira:

Osanjikiza okhazikika (otetezeka):

Zinthu: Zopepuka njerwa zopepuka kapena zotupa zotsika kwambiri (monga dongo).

Ntchito: Kuchulukitsa, kuchepetsa kutentha kwa chipolopolo cham'madzi komanso kuchepetsa kutentha.

Kugwira ntchito (kulumikizana mwachindunji ndi chitsulo chosungunula ndi slag):

Malo a Slag:

Zinthu: Magnesia carbon njerwa (mGA-C, yokhala ndi 10% ~ 20% graphite).

Mawonekedwe: Kukaniza kwakukulu kwa kukokoloka kwa slagg (makamaka alkaline slag), graphite kumapereka chiwopsezo cha mafuta pokana ndi mafuta.

Malo Akhoma:

Zinthu: Aluminium magnesium carbon Brick (Al₂o₃-MGA-C) kapena Aluminium wokwera (Al₂o₃≥80%).
NKHANI: Kusamala kukana kuletsa zitsulo zosungunula ndi mtengo, zoyenera madera omwe si a slag.

Malo Otsika:

Zinthu: Zokwera kwambiri aluminiyam njerwa kapena kuwonongeka kwa bronum (al₂o₃≥90%).
Mawonekedwe: Mphamvu yopanga kwambiri, kukana kuwongolera shael stateic komanso kuvala.

Zogwirizira Ntchito:

Chipata chotsika:

Zinthu: Aluminium zirconium carbon combonon (Al₂o₃-ZRO₂-C) kapena Magnesium Carbon (MGA-C).

Ntchito: Sinthani molondola kutuluka kwa chitsulo chosungunula, ndikuyenera kukana kukokoloka kwakukulu ndi kugwedezeka kwa mafuta.

Kuyeretsa Kutulutsa:

Zinthu: Combig-spinal (Al₂o₃-Mgal₂o₄) kapena Magnesium (MGA).

Ntchito: Sinthani chitsulo chosungunuka ndikuwombera argon / kutentha kwa nitrogen, kutentha kwa yunifolomu ndi kapangidwe kake ndi kovomerezeka komanso kotsutsa.

Chabwino block:

Zinthu: Kwambiri aluminium kapena magnesium carbon.

Ntchito: Konzani chipata ndi kupirira zomwe zimapangitsa kuti zisungunuke zisungunuke.

Zofunikira zomwe zimapangidwira

• Slag Ersous kukana: Malo a Slag a Ladion amafunikira kukana kusintha kwa mankhwala osokoneza bongo (Cao / Sio₂> 2).
• Mafuta osokoneza bongo: Kutentha kumasinthanso kwambiri nthawi yopukutira (monga kuzizira kwambiri kuchokera pa 1600 ° C fitch), ndipo zakuthupi ziyenera kupewa kusweka.
• Kutentha Kwambiri: Kupirira zigawo zokhazikika za chitsulo cholosera (monga pansi pomwe pali matani a matani a 200-0.3mph) ndi kugwedezeka kwamakina.
• Kuwonongeka kochepa: pewani zodetsa mu zinthu zoyimitsa (monga Sio₂) kuti musachokere ndi chitsulo chosungunula komanso kukhudza chipata chachitsulo.

Chisinthiko ndi zovuta za ukadaulo wazinthu

Kukhazikitsa Magnesia Misitima njerwa

Traditional magnesia carbon bricks: Rely on graphite to improve thermal shock resistance, but graphite is easily oxidized (antioxidants such as Al and Si need to be added).

Trandborition yotsika: khalani ndi magborn magneneria carbon borbon (graphite zofanana <8%), m'malo mwa graphite ndi ma carborbon) kapena iTU yamitundu yopanga mpweya.

Kutetezedwa kwachilengedwe ndi chromium-free

Vuto la Chromium Lolight: Mabatani achikhalidwe cha magnesia-chrome (MGGE-CRFOO₃) amaletsedwa chifukwa cha carcinogenicity wa CR⁶⁺.

Njira Yosintha: Gwiritsani ntchito spiewel (Mgal₂o₄) kapena Magnesium-calsium (zida za MGEA-SEO), zomwe zili zonse zachinyengo komanso zachilengedwe.

Kuchulukitsa kwa ntchito

UTHENGA WABWINO: Gwiritsani ntchito alumina-magnesia kapena mitsempha yodutsa m'malo mwamiyala, kuchepetsa kukokoloka kolumikizana ndikuwonjezera moyo wa ntchito.

Kupanga nokha: Ntchito yomanga-gwiritsidwira ntchito imakwaniritsidwa kudzera pa tinthu tating'onotiza, kuchepetsa ndalama.

Zoyenera kulephera pafupipafupi za zinthu zotsekemera

Kusintha kwa Slag: Kulowera kwa slag kumayambitsa mapangidwe a magawo otsika-point (monga Cao-MGA-Sio-Sio-Sio-Sio-Sio-Sio-Sio-Sio-Sio-SGA

Kupsinjika kwa matenthedwe: Kusintha pafupipafupi kumapangitsa kukulitsa ma microluketicks mkati mwazinthuzo, ndipo pamapeto pake kukhetsa.

Blockge ya njerwa za mpweya: zokongoletsa mu chitsulo chosungunuka (monga Al₂o₃) amasungidwa m'mabowo a mpweya, akukhudzanso a Argon.

Kugwiritsa ntchito zida zotsikirazi:

Kusungunula chitsulo choyera: Gwiritsani ntchito njerwa zapamwamba kwambiri za kutchire (Al₂o₃> 99%) kuti muchepetse kukhazikitsidwa kwa zosayera.

Katundu wautali: Yendani ndalama ndi moyo kudzera mwa magrader brobon malo a slag pamtunda wa slag ndi aluminium - magnesium osinthika a khoma la ladewa).

Kuwunikira kwanzeru: Gwiritsani ntchito zojambulajambula zam'madzi kapena ukadaulo wa acoustic kuti ziziwunika mawonekedwe a kukokoloka kwa malo okwererapo kale.

Zinthu zodziwika bwino ndizomwe zimachitika chifukwa cha zopanga zopanga, ndipo momwe amagwirira ntchito mwachindunji zimakhudza mtundu wa chitsulo chosungunula, chitetezo chopanga. Poyerekeza ndi zida zodziwika bwino, zida za tambiri zimafunikira kupirira zitsulo zazitali zosungunuka, zitsulo zovuta kwambiri zachitsulo komanso katundu wapamwamba kwambiri. Mayendedwe amtsogolo akuphatikizapo zinthu zochepa - kaboni komanso zachilengedwe, kapangidwe kake ndi mphamvu yokonza. Mwachitsanzo, kugwiritsa ntchito magnesium - calcium zida za carnium ndi mabwalo omasuka a kaboni sikuti kungosintha kukana slag komanso kukwaniritsa zofunikira zopanga zobiriwira.
