Choyamba, kugwiritsa ntchito carburizing wothandizila mu ng'anjo carburizing njira

1. Mpweya, monga chimodzi mwa zinthu zofunika kwambiri mu chitsulo chosungunuka, ndizovuta kwambiri kusintha kusiyana ndi zinthu zina.Chifukwa mpweya ndi wochepa kwambiri kuposa chitsulo chamadzimadzi, kuyamwa bwino kumakhala kochepa kwambiri popanda kugwedezeka kwakukulu.Kawirikawiri mu batching, mpweya malinga chapamwamba malire a zofunika ndondomeko, ndi kuganizira smelting ndondomeko mpweya woyaka chipukuta misozi, kotero dikirani mpaka zitsulo mlandu bwino, kuchuluka kwa mpweya kwenikweni mu ndondomeko osiyanasiyana, ngakhale pang'ono kupitirira chapamwamba. malire angagwiritsidwenso ntchito kuwonjezera pang'ono (yoyera, youma) zidutswa zosavuta kuzibweretsa pansi, mu ng'anjo yamagetsi kusungunuka mpweya kuposa carburizing ntchito ndi yosavuta.

2. Kudyetsa motsatizana

Khwerero 1: Choyamba ikani ndalama zobwezera (kapena kutsala pang'ono chitsulo chamadzimadzi) pansi pa ng'anjo, kuti zinthu zatsopano zimizidwe muchitsulo chamadzimadzi, kuchepetsa oxidation.

Khwerero 2: Onjezani zitsulo zotsalira poyamba, kenaka yikani carburizing wothandizira.Panthawiyi, chitsulo chosungunuka chachitsulo chimakhala chochepa, chomwe chimatha kusungunuka mwamsanga kuti chiwongolere kutalika kwa madzi, kotero kuti carburizing agent imalowa muchitsulo chamadzimadzi.Kulumikizana kwa carburizing ndi kusungunuka kwachitsulo sikuwonjezera nthawi yosungunuka ndipo kumawononga mphamvu zochepa.Chifukwa mphamvu zochepetsera za FeO ndi C ndizokwera kuposa za Si ndi Mn, kutayika kwa Si ndi Mn kumatha kuchepetsedwa powonjezera carburizer pa kutentha kochepa.Yesani kugwiritsa ntchito zikwama zolongedza zodzaza ndi carburizing agent mung'anjo yamagetsi, osagwiritsa ntchito pinch ya spade mu ng'anjo yamagetsi, kuti tinthu tating'ono tomwe titha kuyamwa ndi wotolera fumbi.

Khwerero 3: Zotsalira zimasungunuka pang'ono ndipo ndalama zobwezera zimawonjezedwa.Kuwonetsetsa kuti carburizing agent yakhazikika kwathunthu isanagwere, pakadali pano, ng'anjo yamagetsi yamphamvu kwambiri (> 600kW / t) ndiyofunikira kwambiri chifukwa nthawi yomwe ikufunika kusungunula zinthuzo ingakhale yocheperapo kuposa nthawi yofunikira kuti mayamwidwe athunthu amve. carburizer.Panthawi imodzimodziyo, ntchito yolimbikitsa ya ng'anjo yamagetsi iyenera kugwiritsidwa ntchito mpaka kufika pamtunda wa carburizing wothandizira.

Khwerero 4: Ngati kuchuluka kwa ma carburizing agent ndi kuwongolera kwa carbon mu chitsulo chamadzimadzi ndikutsimikizika, chosungiracho chikhoza kuwonjezeredwa ndi zidutswa kamodzi.Chowonjezera chachiwiri cha carburizing wothandizila ndikukonza bwino kaboni (kapena chowonjezera chowotcha kaboni), chiyenera kuwonjezeredwa pambuyo pa chitsulo chosungunula madzi, musanalowe m'madzi achitsulo pamwamba pa slag, momwe mungathere kuti mupewe carburizing wothandizira ku slag, ndiyeno. magetsi amphamvu kwambiri pogwiritsa ntchito ng'anjo yamagetsi yamagetsi yosonkhezera kuti azitha kuyamwa bwino.

Khwerero 5: Onjezani ferrosilicon ndi ma aloyi ena, kusanthula zitsanzo, sinthani kapangidwe kake, kuchokera mu uvuni.Pewani kusunga chitsulo chamadzimadzi pa kutentha kwakukulu kwa nthawi yaitali.Kusungidwa kwanthawi yayitali kwachitsulo chamadzimadzi pa kutentha kwakukulu (makamaka kutchinjiriza kwa nthawi yayitali pamwamba pa 1450 ℃) ndikosavuta kutsogolera ku makutidwe ndi okosijeni wa kaboni, kuwonjezeka kwa silicon dioxide (silicon dioxide yafupika) ndi kutayika kwa kristalo muzitsulo zamadzimadzi. .

Awiri, kugwiritsa ntchito carburizing wothandizira mu phukusi carburizing njira

Ngati pakufunika kubisala mu phukusi, tinthu tating'ono ting'onoting'ono ta 100 ~ 300 chitha kuyikidwa pansi pa phukusi, ndipo chitsulo chamadzimadzi chotenthetsera chimatsitsidwa mwachindunji kwa wopangira carburizing (kapena kuwonjezeredwa ndi chitsulo chamadzimadzi. kutuluka), ndipo chitsulo chimagwedezeka kwathunthu pambuyo pa kusungunuka ndi kuyamwa kwa carbon.Zotsatira za carburizing mu phukusi sizofanana ndi zomwe zili mu ng'anjo, ndipo kuchuluka kwa mayamwidwe kumakhala kovuta kulamulira.Mosasamala kanthu za kugwiritsidwa ntchito kwa wothandizila wa carburizing kapena njira yopangira carburizing iyenera kutsimikiziridwa kudzera muyeso yopanga carburizing ndi njira yoyamwitsa ikatsimikiziridwa, musalowe m'malo mwa mtundu wa carburizing wothandizira ndi chiyambi, ngati mukufuna kusintha iyenera kutsimikizira kupanga. kachiwiri.
