Strontium-Silicon(SrSi)
Lebitso la sehlahisoa:Ferro silicon strontium inoculant (SrSi)
Mohlala/Boholo:0-10mm; 5-25mm/10-50mm/0.2-0.7mm/1-6mm
Lintlha tsa Sehlahisoa:
Ferro silicon strontium nucleating agent ke mofuta oa alloy e thehiloeng ho FeSi e nang le palo e itseng ea barium le calcium, e ka fokotsang ho bata haholo, ea hlahisa masala a fokolang haholo.Ka hona, Ferro silicon barium inoculant e sebetsa ho feta inoculant e nang le calcium feela, ho phaella moo, e na le ts'ebetso e ts'oanang ea inoculant eo inoculant e nang le litaba tse phahameng tsa barium le calcium e ka bang le eona.Motsoako oa barium le calcium o na le taolo e betere ea ho bata ho feta ente e nang le calcium feela.
Ferro silicon strontium e sebelisoa haholo joalo ka inoculant ,strontium in ferrosilicon inoculant is one of the most effective elemtnts promotion ,ha great undercooling degree, strontiuim has a special function .ho fokotsa palo ea eutectic group ka fokotsa shrinkage,shrinkage defects of casting.

Ts'ebetso le likarolo:
1. Ho eketseha ka mokhoa o tsotehang oa mantlha oa graphitization, ho hloekisa graphite, ho khothalletsa mofuta oa A-graphite ka tšepe e bohlooho le graphite e atisang ho ba chitja ka tšepe ea ductile, ho ntlafatsa boemo ba spheroidizing;
2. Fokotsa haholo tloaelo ea ho bata, fokotsa boima bo lekanyelitsoeng, ho ntlafatsa ts'ebetso ea ho itšeha;
3. Matla a matla a ho thibela ho putlama ha moruo, ho thibela ente le ho thefula ha moruo;
4. Ntlafatsa homogeneity ea sebaka sa fracture, fokotsa tšekamelo ea ho fokotseha;
5. Sebopeho se tsitsitseng sa lik'hemik'hale, boholo ba likaroloana tse homogeneous, ho kheloha ha ho hlophisoa le ho kheloha ha boleng ho tlaase;
6.Low melting point (haufi le 1300 ℃), e bonolo ho qhibiliha ha ho etsoa inoculation, scum e nyenyane.
Kopo :
Ferro silicon strontium inoculant e loketseng bakeng sa sebabole sa molora o mosesaane kapa o hatselitsoeng o na le bokhoni bo matla ba enke, empa hape le bakeng sa bolo ea tšepe ea ductile ho eketsa palo ea enke, haholo-holo khanyetso e phahameng ea nickel ductile iron (e nang le Ni14%,Cu6%,Cr2). %,Si 1.5%) ho phaella moo, kaha e fokotsa bosoeu ntle le ho eketsa palo ea eutectic haholo, haholo-holo bakeng sa likopo tse hlokang ho lahlela lesela le hlephileng, khatello ea metsi e bohlooho e entsoeng hantle, enke e matla le carbon Si-Ca e qhibilihisitsoeng. inoculant e fapaneng mocheso o lumellehang o tlase .le calcium , palo ea aluminium e tlase, masala a nang le sebopeho se fokolang, ha ho na liphoso tsa ho lahlela vacuum.
