Zomwe zimayambitsa kuwonongeka kwa njerwa zamagetsi

(Chithunzi) Mtundu wa DW wodula njerwa zopumira

Njerwa zopumira ndizapamwamba zogwirira ntchito ndipo sizigwira ntchito mosalekeza panthawi yonse yolowa ndi ma ladle, kuwonongeka kwakuthupi ndi mankhwala kumachitika nthawi zosiyanasiyana. Kutengera zaka 17 za R&D, kupanga, kugulitsa ndikugwiritsa ntchito kwa Luoyang Ke Innovative Materials Co, Ltd., kuwonongeka kwa njerwa zomwe zitha kupumira zitha kugawidwa m’magulu awa:

1 Mpweya woyaka

Lampilo litalumikizidwa nthawi ina chitsulo chisanalumikizidwe, ladle lidzakonzedwa bwino m’malo okonzanso otentha. Pakadali pano, ndikofunikira kuwotcha malo opangira ndi mpweya kuti utsukire zitsulo zotsalira ndi slag pantchito. Mpweya wampweya wampweya umapindulitsa pakugwiritsa ntchito njerwa zopumira. Izi zimatsimikizira kuti malo ogwiritsira ntchito njerwa omwe ali ndi mpweya wabwino komanso magalasi osatsekedwa, kotero kuti mayendedwe a ladle azichitika bwino. Komabe, ndizovuta kumvetsetsa bwino makulidwe azitsulo zotsalira ndi slag pamalo ogwiritsira ntchito mpweya wabwino pamalo otentha. Chifukwa chake, zotsalazo zikachotsedwa, njerwa zopumira ziwotchedwa molakwika kapena mopitilira muyeso. Pansi pa phukusili pakakhala zovuta kapena woyendetsa m’malo otentha akhoza kulakwitsa akaweruzidwa. Kutentha kwa lance ya oxygen kumafika pamwambapa 2000 ℃, ndipo mpweya wotentha kwambiri umapha kwambiri njerwa zopumira. Kutaya kusungunuka m’mphindi zochepa izi kumakhala kokwera kwambiri kuposa kukokoloka kwa nthaka pakugwiritsa ntchito bwino. 2 ~ katatu. Kuti

2 Udindo wamavuto otentha

Zipangizo zokhazikitsira malo opumira njerwa, makamaka zida zopangira mozungulira mpweya wa njerwa zopumira, zimatulutsa kutentha kwakukulu chifukwa cholumikizana mwachindunji ndi chitsulo chosungunuka kwambiri komanso kutenthedwa ndi kutentha kwakukulu chitsulo ndi kutuluka kosalekeza kwa mpweya wozizira. Chifukwa chogwiritsa ntchito mobwerezabwereza, njerwa yopumira imathandizira kwambiri kuzirala komanso kutenthetsa mwachangu, makamaka pafupi ndi mpweya, kupsinjika kwamphamvu kumakulirakulira, ndipo kumamveka ming’alu ndi kusweka.

3 Mawotchi avale

Pakugogoda, kutsitsa kwachangu komanso mwamphamvu kwazitsulo zosungunuka pansi pa ladle kumathandizanso kukokoloka kwa njerwa zomwe zimatha kupumira mpweya. Kafukufuku wokhudzana ndi kuwonongeka kwa njerwa zopumira kudzera pamagetsi oyeserera adapeza kuti mpweya wothamanga kwambiri ukalowetsedwa mu dziwe losungunuka lamadzi, mpweya umabwerera ndikugunda kutsogolo kwa njerwa yopumira, zomwe zimakhudza kwambiri kuzungulira mozungulira njerwa zopumira. . Mlingo wamafuta akamachulukirachulukira, kuchepa kwamafupipafupi kumachepetsedwa, koma mphamvu yakusintha kwamphamvu imakulanso; Kuphatikiza apo, argon ikawombedwa m’malo opopera, ma thovu amphamvu amapanga ndege ya gasi, ndipo ndegeyo imalimbikitsa kusunthira pansi pa ladle. Kuyenda kwamadzimadzi kumunsi kwa ladle kumakulirakulira, ndipo gawo lachiwiri limapangitsa kuti njerwa zotulutsa mpweya zizikhala ndi ubweya wamphamvu komanso kupsinjika. Njerwa yololeza mpweya ikakhala yayitali kuposa njerwa, kumeta ndi kukwapula kwa mtundu uwu wa maula kumawonekera kwambiri. Gawo lalitali kuposa njerwa yam’nyumba limasambitsidwa kamodzi mukamagwiritsa ntchito kamodzi. Chifukwa chake, njerwa zololeza mpweya zikangosinthidwa m’malo, izi nthawi zambiri zimakhala zosavuta kuchitika; Kuphatikiza apo, valavu ikatsekedwa mwachangu itawunikiridwa, kusokonekera kwa chitsulo chosungunulira kumathandizanso kuwonongeka kwa njerwa zopumira.

4 Kuukira mankhwala

Malo ogwirira ntchito njerwa zopumira amakhala ndi nthawi yayitali yolumikizana ndi slag ndi chitsulo chosungunuka, ndipo slag yosungunuka imalowa mosalekeza ndikulowa mu njerwa panthawi yonse yamaphukusi. The oxides MnO, MgO, SiO2, FeO, Fe2O3, etc. mu chitsulo chosungunula ndi chitsulo slag amachita ndi njerwa breathable kupanga otsika limatsogolera ndi zigawo metamorphic. Zinthu zina zosungunuka kwambiri zidzakokololedwa. Ngati kusiyana kwa kutentha pakati pa kutentha ndi kuzizira ndikokulirapo, magwiridwe antchito a metamorphic wosanjikiza ndi thupi la njerwa lopuma limasintha kwambiri, ndikupangitsa kuti njerwa zotulutsa mpweya ziwoneke ndikuchoka chifukwa cha kupsinjika kwamphamvu, komwe kumakhudza kwambiri magwiridwe antchito komanso ngakhale kuyambitsa ngozi.
