I-Strontium-Silicon(SrSi)
Igama lomkhiqizo:I-Ferro silicon strontium inoculant (SrSi)
Imodeli/Usayizi:0-10mm;5-25mm/10-50mm/0.2-0.7mm/1-6mm
Imininingwane Yomkhiqizo:
I-Ferro silicon strontium nucleating agent iwuhlobo lwe-alloy esekelwe ku-FeSi equkethe inani elithile le-barium ne-calcium, inganciphisa ngokuphawulekayo into ebandayo, ikhiqize izinsalela ezincane kakhulu.Ngakho-ke, i-Ferro silicon barium inoculant iphumelela kakhulu kune-inoculant equkethe i-calcium kuphela, ngaphezu kwalokho, inokusebenza okufanayo kwe-inoculant ukuthi inoculant enokuqukethwe okuphezulu kwe-barium ne-calcium ingaba nayo.Inhlanganisela ye-barium ne-calcium inamandla okulawula ukugodola kune-inoculant equkethe i-calcium kuphela.
I-Ferro silicon strontium esetshenziswa kakhulu njenge-casting inoculant, i-strontium ku-ferrosilicon inoculant ingenye yezinto ezikhuthazayo eziphumelela kakhulu, lapho i-undercooling degree enkulu, i-strontiuim inomsebenzi okhethekile .ukunciphisa inani leqembu le-eutectic kunganciphisa ukushwabana, amaphutha okuncipha kokusakazwa.
Umphakeli wegolide waseChina imikhiqizo emisha ye-FeSiSr
Ukucaciswa Okubalulekile :
(Fe-Si-Sr）
| Sr: | Si: | Ca: Max | Al: Max |
| 0.6-1.0% | 46-50% | 0.1% | 0.5% |
| 0.6-1.0% | 73-78% | 0.1% | 0.5% |
| 0.7-1.1% | 73-78% | 0.1% | 0.5% |
| 0.8-1.2% | 73-78% | 0.1% | 0.5% |
| 1.0-1.5% | 70-75% | 0.1% | 0.5% |
| 2.0-3.0% | 70-75% | 0.1% | 0.5% |
Ukusebenza nezici:
1. Ukwandisa ngokuphawulekayo umgogodla we-graphitization, cwenga i-graphite, ukhuthaze uhlobo lwe-graphite yohlobo lwe-A ku-iron empunga kanye ne-graphite evame ukuba yindilinga ku-ductile iron, ithuthukise izinga le-spheroidizing;
2. Nciphisa kakhulu ukuthambekela kokuphola, unciphise ubulukhuni obuhlobene, uthuthukise ukusebenza kokusika;
3. Ikhono eliqinile lokumelana nokuwohloka komnotho, vimbela ukujova kanye nokunciphisa ukuwohloka komnotho ngamaqhuqhuva;
4. Thuthukisa i-homogeneity yendawo yokuphuka, unciphise ukuthambekela kokuncipha;
5. Ukwakheka kwamakhemikhali okuzinzile, usayizi wezinhlayiyana ezilinganayo, ukuchezuka ekubunjweni nasekuphambukeni kwekhwalithi kuphansi;
6.Indawo encibilikayo ephansi (eduze kwe-1300℃), kulula ukuncibilika ekucutshungulweni kokujova, udoti omncane.
Isicelo :
I-Ferro silicon strontium inoculant elungele ukuxutshwa ngodonga oluthambile olunodonga oluncane noma olubandayo lunamandla kayinki aqinile, kodwa futhi nebhola lensimbi elidonsa amanzi ukuze likhulise inani likayinki, ikakhulukazi ukumelana nokugqwala okuphezulu kwe-nickel ductile iron (equkethe i-Ni14%,Cu6%,Cr2 %,Si 1.5%) ngaphezu kwalokho, njengoba kunciphisa okumhlophe ngaphandle kokukhulisa inani le-eutectic, ikakhulukazi izinhlelo zokusebenza ezingadingi ukujiya okuxekethile, ukumelana nokucindezela kwamanzi okumpunga kube nomphumela omuhle, uyinki oqinile kanye ne-carbon Si-Ca encibilikisiwe. izinga lokushisa elivumelekile elivumelekile le-inoculant liphansi .futhi i-calcium , inani le-aluminium liphansi, izinsalela ezinomumo omncane, azikho izinkinga zokukhipha i-vacuum.
