Ntchito zosiyanasiyana recarburizers
Carburizer ndi mankhwala omwe amatha kusintha bwino mphamvu ya carbonization ya zinthu ndi chilengedwe chazitsulo.Pali ma carburizer ambiri omwe amagwiritsidwa ntchito m'makampani achitsulo ndi zitsulo.Ma recarburizer osiyanasiyana pazifukwa zosiyanasiyana amakhala ndi zotsatira zosiyanasiyana.
1. Wopanga graphite recarburizer
Zopangira zazikulu za graphite yokumba ndi ufa wa calcined petroleum coke, momwe phula (kapena pure organic pregelatinization) imawonjezedwa ngati chomangira, ndikuwonjezera pang'ono zida zina zothandizira.Ndi zida zosiyanasiyana zopangira, zimapanikizidwa ndikupangidwa, kenako zimakonzedwa mumlengalenga wopanda oxidizing pa 2500-3000 ° C kuti zikhale graphitized.Pambuyo pa chithandizo cha kutentha kwambiri, phulusa, sulfure ndi gasi zimachepetsedwa kwambiri.
Chifukwa cha kukwera mtengo kwa zinthu zopangira ma graphite, ambiri omwe amagwiritsidwa ntchito popanga ma graphite recarburizer amagwiritsa ntchito zinthu zobwezerezedwanso monga tchipisi, ma electrode otayirira ndi midadada ya graphite popanga ma elekitirodi a graphite m'malo oyambira kuti achepetse ndalama zopangira.Mukasungunula chitsulo cha ductile, kuti chitsulo chosungunula chikhale chapamwamba, recarburizer iyenera kukhala graphite yokumba.
Kugwiritsa ntchito graphite recarburizer: Graphite recarburizer imatha kusintha mawonekedwe a metallographic of castings, kupanga mwachangu graphite pachimake muchitsulo choponyedwa, kufupikitsa nthawi ya carbonization, ndikuwongolera mphamvu ya carbonization.
2. Petroleum coke recarburizer
Petroleum coke ndi recarburizer yomwe imagwiritsidwa ntchito kwambiri, ndipo petroleum coke imachokera ku mafuta oyeretsedwa.Mafuta otsalira ndi mafuta a petroleum omwe amapezedwa ndi kuponderezedwa kapena vacuum distillation angagwiritsidwe ntchito ngati zipangizo zopangira mafuta a petroleum coke, ndipo petroleum coke imatha kupezeka pambuyo pophika.Kutulutsa kwa petroleum coke yaiwisi kumakhala kotsika kuposa kuchuluka kwa mafuta osapsa, ndipo zonyansa zamafuta a petroleum coke ndizokwera, kotero sizingagwiritsidwe ntchito mwachindunji ngati carburizer ndipo ziyenera kuwerengedwa poyamba.Green petroleum coke ili ndi masiponji, singano, granular ndi mawonekedwe amadzimadzi.
Kugwiritsa ntchito mafuta a coke recarburizer: Mafuta a coke recarburizer amatha kuwonjezera kutentha kwa ng'anjo, sikungowonjezera kutentha kwa ng'anjo, komanso kupititsa patsogolo zokolola zazitsulo, kukonza ndi kukonza malo ovuta azitsulo.
3. Coke ndi Anthracite
Popanga zitsulo zamagetsi arc ng'anjo, coke kapena anthracite zitha kuwonjezeredwa ngati recarburizer.ng'anjo yosungunula chitsulo chosungunula sichimagwiritsidwa ntchito kawirikawiri ngati recarburizer chifukwa cha phulusa lake lalitali komanso kusakhazikika.The calciner ndi calcined ndi anthracite, ndi calcination kutentha ndi 1200-1300.Granular wakuda, zitsulo zonyezimira, kaboni 85-93 wosasunthika, sulfure wapakati ndi nayitrogeni.
Kugwiritsa ntchito calcined recarburizer malasha: Cholinga cha calcined malasha recarburizer ndikuwonjezera bwino mpweya ndikufupikitsa nthawi ya carbonization.Kugwiritsa ntchito calcined malasha recarburizer kumatha kupulumutsa nthawi.
