Ma carburizers amagawidwa kukhala: mafuta opangira mafuta a petroleum coke carburizers, graphitized carburizers, carburizers achilengedwe a graphite, metallurgical coke carburizers, calcined malasha carburizers, ma graphite carburizers achilengedwe, ndi ma carburizer azinthu.

Kusiyana kwakukulu pakati pa graphite recarburizers ndi malasha recarburizers ndi:

1. Zopangira ndizosiyana.Graphite recarburizer imakonzedwa ndikuwunika ma graphite achilengedwe, pomwe recarburizer yamalasha imapangidwa kuchokera ku anthracite;

Chachiwiri, makhalidwe ndi osiyana.Graphite recarburizer ili ndi ubwino wa sulfure otsika ndi nayitrogeni, kukana kutentha kwapamwamba, kuyendetsa bwino kwamagetsi, ndi zina zotero, zomwe sizipezeka mu recarburizers za malasha;

Chachitatu, kuchuluka kwa mayamwidwe ndi kosiyana.Kuchuluka kwa mayamwidwe a graphite recarburizer kumatha kufika kupitirira 90%, kotero ngakhale mpweya wa graphite recarburizer suli wokwera, ukhoza kukwaniritsa zofunikira zogwiritsira ntchito;

Chachinayi, mtengo wake ndi wosiyana.Ngakhale mtengo wa graphite recarburizer ndi wokwera, mtengo wake wogwiritsa ntchito ndi wotsika kwambiri.

Carburization ya carburizer imachitika ndi kusungunuka ndi kufalikira kwa kaboni muchitsulo chosungunuka.Kafukufuku wasonyeza kuti pamene mpweya wa iron-carbon alloy ndi 2.1%, graphite recarburizers ndi osakhala graphite recarburizers amachita mofanana chifukwa chonyowetsa thupi;koma pamene carbon zili mu chitsulo chosungunuka ndi chachikulu kuposa 2.1%., The graphite mu graphite recarburizer akhoza mwachindunji kusungunuka mu chitsulo chosungunuka, ndipo chodabwitsa ichi angatchedwe kusungunuka mwachindunji.Kusungunuka kwachindunji kwa non-graphite recarburizer kulibe, koma kaboni pang'onopang'ono imafalikira ndikusungunuka muchitsulo chosungunula pakapita nthawi.Chifukwa chake, mulingo wa carbonation wa graphite recarburizer ndiwokwera kwambiri kuposa wa non-graphite recarburizer.

Mafunso oyenera kusamala posankha carburant:

1. Yesetsani kugwiritsa ntchito ma recarburizer omwe amapangidwa ndi kutentha kwambiri (kutentha kwambiri kwa mankhwala, kumapangitsanso kuti graphitization ikhale yabwino), monga ma electrode a graphite kapena coke yamafuta a graphitized.Chifukwa recarburizer yabwino imakhala ndi kuchuluka kwa mayamwidwe komanso kusungunuka mwachangu, ndizothandiza kuchepetsa kugwiritsa ntchito mphamvu, ndipo imatha kukulitsa nucleation pachimake chachitsulo chosungunuka ndikuwongolera zitsulo;

2. Sankhani ma carburizer okhala ndi zinthu zochepa zonyansa monga sulfure ndi nayitrogeni.Nayitrogeni wa recarburizer wokhala ndi sulfure wambiri ndiwokweranso.Pamene nayitrogeni zili mu imvi chitsulo chosungunula chitsulo ndi apamwamba kuposa equilibrium ndende, n'zosavuta kutulutsa mng'alu ngati nayitrogeni pores, ndi ductile chitsulo chosungunula chitsulo sachedwa shrinkage kupunduka mbali wandiweyani-mipanda, ndi zili zonyansa ndi. apamwamba.Wonjezerani chizoloŵezi cha kuponyedwa kwa slag;

3. Malinga ndi makulidwe osiyanasiyana ang'anjo, kusankha kukula kwa tinthu koyenera ka recarburizer kumatha kupititsa patsogolo kuthamanga kwa mayamwidwe ndi kuchuluka kwa carburant ndi chitsulo chosungunuka.
