Indima yezakhi ze-alloy ensimbi empunga

1. I-manganese nesibabule
Generally speaking, sulfur is a harmful element. But for gray cast iron, a small amount of sulfur plays a very important role in the refinement of graphite core and cocrystal groups. Therefore, the sulfur content in gray cast iron should not be less than 0.06%, and it is best to keep between 0.06% and 0.08%. If the sulfur content is too high (>0 {., zonke izinhlobo zemiphumela elimazayo zizovela futhi zilimaze ikhwalithi yokuphonsa.
I-Sulfur iyinto enomsebenzi oqinile wamakhemikhali
I-Fes ingaqedwa ngokuphelele kukhambi lensimbi
E-Srey Cast Iron, Ubudlelwano besibabule kanye ne-manganese bukhulu kakhulu kunalokho kwensimbi, futhi ukwakheka kwe-MNS kuhamba phambili ekuphenduleni okuchazwe ku-equation elandelayo .
MN + FES MNS + FE
Iphoyinti lokuncibilika le-MNS liyi-1620℃. Ukufakwa kwensimbi empunga, ukufakwa okuluhlaza okwesibhakabhaka okuluhlaza okwesibhakabhaka, okusakazeka ukusatshalaliswa ku-matrix yensimbi, futhi kusiza ukuthuthukisa ukusebenza kwensimbi futhi kuthuthukise impilo yamathuluzi .
E-Iron empunga, i-MNS kanye ne-Fes kungahlangana, ngakho-ke inani lama-manganese kanye nesibabule e-sulfide ({0 izoshintsha ngezimo ezithile ze-cast iron .
Eminyakeni yamuva nje, ucwaningo ngokuhlaziywa kwe-metallographic okunobuningi kukhombisile ukuthi kunezinto ezingaba yizigidi ezingama-43 ze-MNS kanye (MNFE) Ash iron iron, kanti ubukhulu be-ash . Inani eliphelele le-0
Lapho i-sulphur ikhona kwi-fes noma i-crystal ye-ternary, it ehlukaniswa esigabeni se-liquid endaweni yokuvimbela i-cofrystal kwinqubo yokuqina, bese ikhulisa ukukhula komsindo we-co-cast Iqembu leCocryStal lizokwenza izici zemishini ze-Iron Low Low ne-Brittleness ezinkulu . Lokhu kuwumphumela olimazayo we-sulfur .
Uma amanani ezanele ama-manganese angezwa e-Iron ye-Iron ukuvimbela ukukhiqizwa kwe-FES futhi akha i-sulfide ukufakwa okuhle kwe-crystal encane, i-graphite ye-graphiner E-Iron engwevu empunga kufanele ibe ngu-0 {{3} . Okuqukethwe kwesibabule kuphansi kunaleli nani, futhi kusatshalaliswa kwe-graphite sheet ku-iron i-iron kubi, futhi kulula ukukhiqiza umlomo omhlophe.
Iqhaza eliphambili le-Manganese e-Iron Grey Cast ukunqanda isibabule futhi livimbela ukwakheka okulinganayo kwe-momic
