Amapayipi Ensimbi E-Ductile Asebenza Ngamapayipi Ensimbi
Incazelo Yokukhiqiza
● Ukumuncwa ukushaqeka.Ukumuncwa okushaqisayo kwe-iron ductile kungcono kunokwensimbi empunga.Lapho izinga le-spheroidization liphezulu, kuncane ukumuncwa kokushaqeka.Njengoba izinga lokushisa likhuphuka, ukumuncwa kwensimbi empunga kuncipha, kodwa umphumela ku-ductile iron mncane.
● ukusika ukusebenza.I-Ductile iron iqukethe i-graphite eyengeziwe, edlala indima ekusikeni ukuthambisa.Ngakho-ke, ukumelana nokusika kwensimbi ye-ductile kungaphansi kwensimbi, futhi isivinini sokusika siphezulu.
● Ukushisela.I-Ductile iron ayikwazi ukushiselwa, ilungiswa kuphela ngokushisela.Lapho okuqukethwe kwe-magnesium alloy yomhlaba engavamile ku-ductile iron kuphezulu, kulula ukukhiqiza umlomo omhlophe noma isakhiwo se-martensitic ukwakha ukucindezeleka kwangaphakathi nokuqhekeka endaweni eseduze ne-weld.
● Ukumelana nokushisa.I-graphite eku-ductile iron iyahlukana ukusuka kwenye, okuvimbela ukusakazeka komoyampilo emazingeni okushisa aphezulu uma kuqhathaniswa ne-grey cast iron.Ngakho-ke, ukumelana ne-oxidation kanye nokumelana nokukhula kwe-ductile iron kungcono kunaleyo ye-grey cast iron nensimbi ethambileyo.Ukumelana nokukhula kwezinga lokushisa okuphezulu kwe-ferritic ductile iron kungcono kune-pearlitic ductile iron.Ukwandisa okuqukethwe kwe-silicon noma i-aluminium kungathuthukisa ukumelana ne-oxidation kanye nokumelana nokushisa kwe-ductile iron.
● Ukumelana nokugqwala.I-Ductile iron kanye ne-grey cast iron inokumelana nokugqwala okuhle kusixazululo se-alkali, futhi ukumelana nokugqwala kwe-ductile iron kuya ezintweni eziphilayo, ama-sulfide, nezinsimbi ezincibilikisiwe (iphuzu elincibilikayo eliphansi) kufana nalokhu kwensimbi empunga.
● Ukumelana nemihuzuko.I-Ductile iron iyinto enhle ekwazi ukumelana nokugqokwa futhi enciphisa ukugqokwa, futhi ukumelana kwayo nokugqoka kungcono kunokwensimbi empunga, insimbi ye-carbon steel kanye nensimbi ene-alloy ephansi ene-matrix efanayo.
● (1) Ukugcotshwa nokumelana nokugqoka, ukumelana nokugqokwa kwe-ductile iron kungcono kunokwensimbi empunga.
● (2) Ukuguga, insimbi edonsa amanzi nayo inokusetshenziswa okuthile ngaphansi kwezimo zokugwaza.Kodwa-ke, uma kuqhathaniswa ne-white cast iron kanye ne-low alloy iron, ukumelana nokugqokwa kwensimbi evamile ye-ductile akukuhle kakhulu, i-alloy ductile iron kuphela noma i-alloy I-Bainite ductile iron inokumelana okuhle nokugqokwa.
Indawo Yesicelo
Isetshenziselwa ukuthuthwa kwezinhlobo ezahlukene zamanzi (isibonelo: amanzi aluhlaza, amanzi ahlanzekile, ukusetshenziswa kabusha kwamanzi, njll.)
