Kugwiritsa ntchito Recarburizer

1. Njira yolowera m'ng'anjo:

Recarburizer ndiyoyenera kusungunuka mu ng'anjo yolowera, koma kugwiritsa ntchito kwake sikufanana malinga ndi zofunikira za ndondomekoyi.
(1) Kugwiritsa ntchito recarburizer mu ng'anjo yamagetsi yapakati pafupipafupi kumatha kuwonjezeredwa pakatikati ndi m'munsi mwa ng'anjo yamagetsi malinga ndi chiŵerengero kapena zofunikira zofanana ndi mpweya, ndipo kuchira kumatha kufika kupitirira 95%;
(2) Chitsulo chosungunuka ngati kuchuluka kwa mpweya sikukwanira kusintha nthawi ya kaboni, choyamba kuyeretsa slag yosungunuka mu ng'anjo, ndiyeno onjezerani recarburizer, kupyolera mu kutentha kwachitsulo chamadzimadzi, maginito oyambitsa magetsi kapena opangira kupanga kuti asungunuke mayamwidwe a carbon, chiwongola dzanja chikhoza kukhala pafupifupi 90, ngati kutsika kwa kutentha kwa carburizing, ndiye kuti, mtengowo umangosungunula gawo la kutentha kwachitsulo chosungunuka ndi chochepa, zonse zopangira carburizing zimawonjezeredwa kuchitsulo chamadzimadzi nthawi imodzi.Pa nthawi yomweyi, imakanikizidwa mumadzi achitsulo ndi chiwongolero cholimba kuti isawonetsere madzi achitsulo pamwamba pake.The carburization wa chitsulo chamadzimadzi mu njira iyi akhoza kufika oposa 1.0%.

2. Kunja kwa ng'anjo yamoto:

(1) Phukusili limapoperedwa ndi ufa wa graphite, ufa wa graphite umagwiritsidwa ntchito ngati recarburizer, ndipo kuchuluka kwake ndi 40kg / t, zomwe zikuyembekezeka kuonjezera mpweya wa chitsulo chamadzimadzi kuchokera ku 2% mpaka 3%.Pamene mpweya wa carbon mu chitsulo chamadzimadzi ukuwonjezeka pang'onopang'ono, kuchuluka kwa magwiritsidwe ntchito a carbon kunachepa.Kutentha kwachitsulo chamadzimadzi kusanachitike carburization kunali 1600 ℃, ndipo kutentha kwapakati pambuyo pa carburization kunali 1299 ℃.Graphite ufa carburization, ambiri ntchito nayitrogeni monga chonyamulira, koma mu zinthu mafakitale kupanga, wothinikizidwa mpweya ndi yabwino, ndi mpweya wothinikizidwa mpweya kuyaka kutulutsa CO, mankhwala anachita kutentha akhoza kulipira mbali ya dontho kutentha, ndi kuchepetsa CO. mpweya umathandizira kuwongolera mphamvu ya carburization.
(2) Kugwiritsa ntchito recarburizer pamene chitsulo, akhoza kukhala 100-300mesh graphite ufa recarburizer mu phukusi, kapena kuchokera chitsulo ufa ndi otaya mu, pambuyo madzi chitsulo ndi mokwanira anasonkhezereka, mmene ndingathere kupasuka mayamwidwe mpweya, mpweya. kuchira pafupifupi 50%.
