Kumgaqo wangoku wokwenziwa kwezigqubuthelo zomngxuma wentsimbi, sinokwenza intsimbi edityanisiweyo ngentsimbi etyhidiweyo kunye nentsimbi ebunjiweyo, esetyenziswa kakhulu kushishino lokwenziwa koomatshini namhlanje.Enyanisweni, umgaqo we-iron ductile kukufumana i-graphite enesimo esifanayo nebhola ngokusebenzisa inkqubo ye-spheroidization, ephucula ngokufanelekileyo ukusebenza kwentsimbi, ngakumbi iplastiki kunye nokuqina kwayo, okubangelwa umgangatho ophezulu kune-carbon steel.Nangona kunjalo, ukuze kuncitshiswe iindleko, izigqubuthelo zentsimbi ye-ductile zenziwa ngokubanzi kusetyenziswa intsimbi kunye nentsimbi.
I-iron ductile yinto enqabileyo.Okokuqala, isinyithi esityhidiweyo sithetha umxholo wekhabhoni omkhulu kune-2.1% (kunye nomxholo wekhabhoni we-3.50-3.90% kunye nesakhiwo se-metallographic se-ferrite + pearlite).Ukuba umxholo wekhabhoni uphezulu, ubunzima bayo ngokuqinisekileyo buya kuba phezulu.Okwesibini, i-spheroidizing i-iron ductile ithetha ukuba ubukhulu beengqungquthela zetsimbi buyancipha, okuya kuphucula amandla kunye nobunzima bezinto.Ukuthetha ngokubanzi, ukuqina kwentsimbi ye-ductile kuphezulu kakhulu (ngokuqinisekileyo kuphezulu kunokwentsimbi eqhelekileyo).
Okokuqala, izithuthi ezinzima zidla ngokusetyenziswa kwiindlela zokuhamba, ngoko ke izigqubuthelo zomngxuma wentsimbi zikhethwa ngokuqhelekileyo, ezinomthamo wokuthwala malunga neetoni ezingama-40;Ezinye izigqubuthelo zomngxuma ezidityanisiweyo zinokufikelela kwisakhono sokuthwala malunga neetoni ezingama-25, nto leyo enexabiso eliphantsi kune-ayini yentsimbi.Nangona kunjalo, izigqubuthelo zomngxuma wentsimbi zikhuselekile ngokwentelekiso.
Okwesibini, xa kuthelekiswa nezigqubuthelo zomngxuma odityanisiweyo, izigqubuthelo zomngxuma wentsimbi zidla ngokujoliswa ngamasela.Izigqubuthelo zomngxuma wentsimbi azigcini nje ngokuba nomthamo olungileyo wokuthwala, kodwa zikwagxininise kuyilo lwazo zonke iinkcukacha zokugquma komngxuma wentsimbi, ngakumbi ngokwemigaqo yokuchasana nobusela, ukunyanzeliswa kwamasela ngokwenene ukuya kutsho apho bengenandlela yokuqalisa. kwaye akukho bani unokuba.Abanye abantu banokuba nexhala lokuba izigqubuthelo zomngxuma wentsimbi zingenza ingxolo enkulu xa uqhuba, nto leyo engeyomfuneko kuba sele siwuqwalasele lo mba kuyilo lwethu.Umngxuma ngamnye ogqunyiweyo uye wafumana unyango lokunciphisa ingxolo phambi kokuba ushiye umzi-mveliso, nto leyo eyahlula ngokupheleleyo ingxaki yongcoliseko lwengxolo yezigqubuthelo zomngxuma wentsimbi.
Okokugqibela, umthamo wokuthwala umthwalo wezinto ezigqunyiweyo zokugquma umngxuma odityanisiweyo ungaphantsi kakhulu kunobo bugqubuthele umngxuma wentsimbi.Kwiindawo ezinjengamabhanti aluhlaza kunye neendledlana zeenyawo ezingadingi xinzelelo lubalulekileyo, iindleko zokusebenzisa izigqubuthelo zomngxuma odibeneyo zingaphantsi kakhulu kunokusebenzisa izigqubuthelo zentsimbi yentsimbi.
