Imibhobho ye-Iron yeDuctile yobuNgqongileyo
Inkcazo yeMveliso
● Ukufunxa ngokothusayo.Ukufunxwa komothuko we-iron ductile kungcono kunokwentsimbi engwevu.Okukhona liphezulu izinga le-spheroidization, kokukhona ukufunxa kuncinci.Njengoko iqondo lobushushu linyuka, ukufunxwa kwentsimbi engwevu kuyancipha, kodwa umphumo kwi-ductile iron uncinci.
● ukusika ukusebenza.I-iron ductile iqulethe i-graphite eninzi, edlala indima ekusikeni ukuthambisa.Ngoko ke, ukuchasana kokusika kwensimbi ye-ductile iphantsi kuneyentsimbi, kwaye isantya sokusika siphezulu.
● Ukuwelda.I-Ductile iron ayinakudityaniswa, ilungiswa kuphela nge-welding.Xa umxholo womhlaba onqabileyo we-magnesium alloy kwi-ductile iron ephezulu, kulula ukuvelisa umlomo omhlophe okanye isakhiwo se-martensitic ukwenza uxinzelelo lwangaphakathi kunye neentanda kwindawo ekufutshane ne-weld.
● Ukumelana nobushushu.I-graphite kwi-ductile iron iyahlukana enye kwenye, ethintela ukusasazwa kweoksijini kumaqondo obushushu aphezulu xa kuthelekiswa nentsimbi engwevu.Ke ngoko, ukuxhathisa kwe-oxidation kunye nokumelana nokukhula kwe-iron ductile kungcono kunezo zentsimbi ezingwevu kunye nentsimbi ethambileyo.Ukumelana nokukhula kobushushu obuphezulu bentsimbi ye-ferritic ductile ingcono kune-pearlitic ductile iron.Ukwandisa umxholo we-silicon okanye i-aluminium kunokuphucula ukuxhathisa i-oxidation kunye nokumelana nokushisa kwentsimbi ye-ductile.
● Ukumelana nokubola.Isinyithi se-Ductile kunye ne-grey cast iron inokumelana nokugqwala okulungileyo kwisisombululo se-alkaline, kunye nokuxhatshazwa kwe-corrosion ye-iron ductile kwizinto eziphilayo, i-sulfides, kunye nesinyithi esityhidiweyo (indawo encibilikayo ephantsi) ifana ne-grey cast iron.
● Ukuxhathisa i-brasion.Intsimbi ye-Ductile yinto efanelekileyo yokunxiba kunye nokunciphisa ukunxiba, kwaye ukuxhathisa kwayo kubhetele kunokwentsimbi ye-grey cast, i-carbon steel kunye nentsimbi ephantsi kwe-alloy kunye ne-matrix efanayo.
● (1) I-Lubrication kunye nokumelana nokugqoka, ukuxhatshazwa kwentsimbi ye-ductile kungcono kune-grey cast iron.
● (2) I-abrasive wear, i-ductile iron nayo inezicelo ezithile phantsi kweemeko zokugqoka ezinqabileyo.Nangona kunjalo, xa kuthelekiswa nentsimbi emhlophe kunye nentsimbi ephantsi ye-alloy, ukuxhathisa ukunxitywa kwentsimbi eqhelekileyo ye-ductile ayilungile kakhulu, kuphela i-alloy ductile iron okanye i-alloy Bainite ductile iron inokumelana nokunxiba kakuhle.
Indawo yesicelo
Isetyenziselwa ukuthuthwa kweentlobo ezahlukeneyo zamanzi (umzekelo: amanzi akrwada, amanzi acociweyo, ukusetyenziswa kwakhona kwamanzi, njl.njl.)
