Isiphumo sei-spheroidizer(i-nodularizer)kwintsimbi etyhidiweyo iphindwe kabini:
1, Umhlaba onqabileyo njenge-nodulating agent enyibilikisiweyo kwintsimbi etyhidiweyo inefuthe elinamandla ekubunjweni kwe-carbide.Iyinto echasene ne-antigraphitized.Nangona kunjalo, ukongeza inani elincinci lomhlaba onqabileyo kwi-spheroidizer esekelwe kwi-magnesium inokunyusa kakhulu izinga lokunyibilika kwe-cast. I-iron.Nciphisa;Ukuba isixa sokudibanisa sikhulu, utyekelo lwentsimbi etyhidiweyo luza kuphuculwa.Le nto ibonakala iphikisana ayichasananga.Kuba imihlaba enqabileyo inamandla amakhulu okudibanisa nesulfure kunye neoksijini.
2, Xa ii-spheroidizer iqulethe izinto ezinqabileyo zomhlaba, i-sulfide kunye nee-oxides zizinzile kakhulu, ubungakanani bamasuntswana amancinci, kunzima ukudada kwintsimbi etyhidiweyo. I-graphite nuclei.I-Magnesium oxide i-MgO yi-arhente ye-spheroidizing enendawo yokunyibilika ephezulu, uzinzo oluhle kunye nokunyibilika okuphantsi kwintsimbi etyhidiweyo, kodwa xa ubungakanani besuntswana bukhulu kancinane, buya kudada phezu komhlaba ukuze bube ngumgquba, okanye bunokubandakanyeka ukuphosa ukubandakanywa kwe-slag.
I-Nodulizer(ReMgSiFe),yinto ekhobokisayo enokukhuthaza ukwenziwa kwegraphite engqukuva kwiziqwenga zegraphite kwiinkqubo zemveliso.Iyakwazi ukukhuthaza iigrafu ze-spheroidal kunye nokwandisa inani leegrafu ze-spheroidal ukwenzela ukuba iimpawu zabo zomatshini ziphuculwe.Ngenxa yoko, i-ductility kunye nokuqina kweemveliso kuye kwaphuculwa ukuze amandla kunye nemisebenzi yabo iqiniswe kakhulu.
Ubunzima obunqabileyo-umhlabaii-nodulersukonwabela izakhono eziqinileyo kunye ne-anti-recession, anti-distortion kunye ne-anti-interference kwinkqubo yokuvelisa.I-magnesia yayo ilawulwa ngokusisiseko ngaphakathi kwe-0.6%.Ngesinyithi esinyibilikisiweyo esizinzileyo sokuqala kunye netekhnoloji yokuvuthwa kwamaqhuqhuva, i-magnesium eshiyekileyo inokulawulwa ngokuzinzileyo.
