Momwe mungasankhire recarburizer yapamwamba kwambiri yopanga zitsulo
Pakusungunula, chifukwa cha batching molakwika kapena kulipiritsa komanso decarburization kwambiri, nthawi zina mpweya wa kaboni muzitsulo kapena chitsulo sichimakwaniritsa zofunikira.Panthawiyi, carbon iyenera kuwonjezeredwa kuchitsulo kapena chitsulo chosungunuka.Zida zazikulu zomwe zimagwiritsidwa ntchito popanga carbonization ndi ufa wa anthracite, chitsulo cha nkhumba cha carbonized, electrode powder, petroleum coke powder, pitch coke, makala amoto ndi coke powder.Zomwe zimafunikira pa recarburizers ndikuti kukweza kwa mpweya wokhazikika, kumakhala bwino, komanso kutsika kwa zonyansa zovulaza monga phulusa, zinthu zosasunthika ndi sulfure, ndibwino, kuti zisawononge chitsulo.
Kusungunula kwa ma castings kumagwiritsa ntchito ma recarburizer apamwamba kwambiri pambuyo powerengera kutentha kwambiri kwa petroleum coke yokhala ndi zonyansa zochepa, chomwe ndi ulalo wofunikira kwambiri pakubwezeretsanso.Ubwino wa recarburizer umatsimikizira mtundu wa chitsulo chosungunula, komanso umatsimikizira ngati zotsatira zabwino za graphitization zitha kupezeka.Mwachidule, kuchepetsa kuchepa kwachitsulo chosungunuka ndi ma recarburizers kumagwira ntchito yofunika kwambiri.
Chitsulo chonsecho chikasungunuka mung'anjo yamagetsi, graphitized recarburizer imakonda.Pambuyo pa kutentha kwapamwamba kwa graphitization mankhwala, ma atomu a carbon amatha kusintha kuchokera ku dongosolo losasinthika kupita ku dongosolo la flake, ndipo graphite ya flake imatha kukhala ngati graphite.Zabwino pachimake pachimake, kuti atsogolere Kukwezeleza graphitization.Chifukwa chake, tiyenera kusankha recarburizer yomwe yadutsa kutentha kwambiri kwa graphitization.Chifukwa cha kutentha kwapamwamba kwa graphitization mankhwala, sulfure zomwe zili ndi sulfure zimachepetsedwa ndi kuthawa kwa mpweya wa SO2.Chifukwa chake, ma recarburizer apamwamba kwambiri amakhala ndi sulfure yotsika kwambiri, ma w(ma) nthawi zambiri amakhala osakwana 0.05%, ndipo ma w(ma) abwino amakhala ochepera 0.03%.Panthawi imodzimodziyo, ichi ndi chizindikiro chosalunjika kuti chiweruze ngati chakhala chikuchitidwa ndi chithandizo cha kutentha kwa graphitization komanso ngati graphitization ndi yabwino.Ngati recarburizer yosankhidwayo sanalandire chithandizo chapamwamba cha kutentha kwa graphitization, mphamvu ya nucleation ya graphite idzachepetsedwa kwambiri, ndipo luso la graphitization lidzafooka.Ngakhale kuchuluka kwa carbon kungatheke, zotsatira zake zimakhala zosiyana kwambiri.
Zomwe zimatchedwa recarburizer ndikuwonjezera bwino zomwe zili mu chitsulo chosungunula mutatha kuwonjezera, kotero kuti zomwe zili mu carbon recarburizer siziyenera kukhala zotsika kwambiri, apo ayi kuti mukwaniritse mpweya wina, ndikofunikira kuwonjezera mpweya wochuluka kwambiri. zomwe zili.Zitsanzo zambiri za recarburizer mosakayikira zidzachulukitsa kuchuluka kwa zinthu zina zosasangalatsa mu recarburizer, kuti chitsulo chosungunula chitha kupeza zabwinoko.
Mafuta a sulfure otsika, nayitrogeni ndi haidrojeni ndiye chinsinsi choteteza ma pores a nayitrogeni m'mapangidwe, kotero kutsika kwa nayitrogeni mu recarburizer kumakhala bwinoko.Zizindikiro zina za recarburizer, monga chinyezi, phulusa, ndi zinthu zosasunthika, kutsika kwa mpweya wokhazikika, kuchuluka kwa carbon yokhazikika, kotero kuti kuchuluka kwa carbon yokhazikika, zomwe zili m'zigawo zovulazazi siziyenera kukhala. apamwamba.
Malinga ndi njira zosiyanasiyana zosungunulira, mitundu ya ng'anjo ndi kukula kwake kwa ng'anjo zosungunulira, ndikofunikiranso kusankha kukula koyenera kwa tinthu tating'onoting'ono ta recarburizer, komwe kumatha kukweza bwino mayamwidwe ndi mayamwidwe achitsulo chosungunula ku recarburizer, ndikupewa vuto la tinthu tating'ono kwambiri.Zimayambitsidwa ndi kutenthedwa kwa okosijeni kwa recarburizers.
Tinthu kukula kwake makamaka: 100kg ng'anjo zosakwana 10mm, 500kg ng'anjo zosakwana 15mm, 1.5 tani ng'anjo zosakwana 20mm, 20 tani ng'anjo zosakwana 30mm.Mu smelting converter, pamene chitsulo cha carbon high chikugwiritsidwa ntchito, recarburizer yokhala ndi zonyansa zochepa imagwiritsidwa ntchito.Zofunikira zopangira ma recarburizer pakupanga zitsulo zowombedwa kwambiri ndi mpweya wokhazikika, phulusa lochepa, losakhazikika komanso sulufule, phosphorous, nayitrogeni ndi zonyansa zina, zowuma, zoyera komanso zocheperako.Mpweya wake wokhazikika wa carbon C ≥ 96%, chinthu chosasinthika ≤ 1.0%, S ≤ 0.5%, chinyezi ≤ 0.5%, kukula kwa tinthu 1-5mm.Ngati tinthu tating'onoting'ono tating'ono tating'ono tating'onoting'ono, timatentha mosavuta, ndipo ngati ndi lalikulu kwambiri, limayandama pamwamba pa chitsulo chosungunuka ndipo sichimatengedwa mosavuta ndi chitsulo chosungunuka.Kwa ng'anjo zopangira ng'anjo, kukula kwa tinthu ndi 0.2-6mm, komwe chitsulo ndi golide wina wakuda ndi 1.4-9.5mm, chitsulo cha carbon high chimafuna nayitrogeni wochepa, ndipo kukula kwa tinthu ndi 0.5-5mm, ndi zina zotero. mtundu wa ng'anjo yeniyeni kuti usungunuke workpiece Mitundu ndi zina za chiweruzo chenichenicho ndi kusankha.
