Ilizwe lethu lihlala linamathele ukubaluleka okukhulu kwimveliso kunye nokusetyenziswa kwezixhobo ze-metallurgical, kwaye iphumelele uphuhliso oluhle kwiminyaka yamuva.Sonke siyazi ukuba i-steelmaking kunye ne-cast iron industry iye yahlala ingamashishini amakhulu kwi-industry field.Bavelisa amashishini aneenkcazo ezahlukeneyo kunye neepropati, ezinefuthe elihle lokukhuthaza kuphuhliso lwemizi-mveliso.Le ikwayimeko eyimfuneko yokuqhuba ukukhula koqoqosho.
I-spheroidal graphite kwi-ductile iron yenziwa ngonyango lwe-spheroidizing yentsimbi etyhidiweyo, iyenza yomelele ngakumbi kunentsimbi etyhidiweyo engwevu kwaye yomelele kunentsimbi etyhidiweyo etyhidiweyo, ngelixa igcina uthotho lweenzuzo zentsimbi ephoswe ngengwevu.Nangona kunjalo, "i-agent ye-spheroidizing" esetyenziselwa ukunyibilika kunye nokuphosa intsimbi ye-ductile inokunyusa ukuthambekela kwe-weld ukuvelisa "amabala amhlophe" kunye nezakhiwo ezilukhuni, ezibangela ukuqhekeka kwi-weld kunye nommandla ochaphazelekayo ubushushu.
Ingabonwa ukuba i-spheroidizing agents zidlala indima ebaluleke kakhulu kwishishini lesinyithi, kwaye okwangoku akukho zixhobo ezininzi ze-metallurgical ezineempembelelo ze-spheroidizing.Xa umzi-mveliso uvelisa, akufuneki kuphela ukuba iqwalasele impembelelo ye-spheroidization, kodwa ineemfuno zokusetyenziswa kwemveliso kunye nokonga amandla kunye nokunciphisa ukusetyenziswa, kwaye inokuphunyezwa kuphela phantsi kwemigangatho yemveliso yelizwe lam.
Uninzi lwezixhobo eziqhelekileyo zentsimbi kwishishini zifumaneka emva konyango nge-agent ye-spheroidizing.Inokubonwa ukuba iimveliso ze-ejenti ye-spheroidizing ziya kudlala indima enkulu kuphuhliso lwexesha elizayo kwaye zikwayinto eyimfuneko kwimathiriyeli yesinyithi kwindawo yoshishino.Singumvelisi oqeqeshiweyo weemveliso ze-metallurgical.Iimveliso zenkampani ziphelele ngokwahlukeneyo kwaye zikumgangatho olungileyo.Samkela abathengi abatsha nabadala ukuba basitsalele umnxeba baze bafake iiodolo.
