IStrontium-Silicon(SrSi)
Igama lemveliso:Ferro silicon strontium inoculant (SrSi)
Imodeli/ubungakanani:0-10mm;5-25mm/10-50mm/0.2-0.7mm/1-6mm
Iinkcukacha zeMveliso:
I-Ferro silicon strontium nucleating agent luhlobo lwe-alloy esekwe kwi-FeSi equlethe isixa esithile se-barium kunye ne-calcium, inokunciphisa ngokuphawulekayo i-chill phenomenon, ivelise intsalela encinci kakhulu.Ngoko ke, i-Ferro silicon barium inoculant iphumelele ngakumbi kune-inoculant equkethe i-calcium kuphela, ngaphezu koko, inokusebenza okufanayo kwe-inoculating ukuba i-inoculant enomxholo ophezulu we-barium kunye ne-calcium iya kuba nayo.Indibaniselwano ye-barium kunye ne-calcium inokulawula ngcono ukubanda kune-inoculant ene-calcium kuphela.
I-Ferro silicon strontium isetyenziswa kakhulu njenge-inoculant yokuphosa, istrontium kwi-ferrosilicon inoculant yenye yezona zinto zisebenzayo zokunyusa, xa idigri enkulu epholileyo, i-strontiuim inomsebenzi okhethekileyo .ukunciphisa inani leqela le-eutectic kunokunciphisa ukushwabana, ukushwabana kweziphene zokuphosa.
Umthengisi wegolide waseTshayina iimveliso ezintsha zeFeSiSr
IiNgcaciso eziphambili :
(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% |

| 2.0-3.0% | 70-75% | 0.1% | 0.5% |
Ukusebenza kunye neempawu:
1. Ukwandisa kakhulu i-graphitization core, ukucokisa igraphite, ukukhuthaza i-graphite yohlobo lwe-A kwintsimbi engwevu kunye ne-graphite ethande ukuba yingqukuva kwi-ductile iron, ukuphucula inqanaba le-spheroidizing;
2. Ukunciphisa kakhulu ukuthambekela okubandayo, ukunciphisa ubunzima obuhambelanayo, ukuphucula ukusebenza kokusika;
3. Amandla okumelana nokudodobala koqoqosho, ukuthintela ukugonywa kunye nokunciphisa ukudodobala koqoqosho;
4. Ukuphucula i-homogeneity ye-fracture surface, ukunciphisa ukuthambekela kokunciphisa;
5. Ukubunjwa kweekhemikhali ezizinzileyo, ubungakanani be-particle homogeneous, ukutenxa ekubunjweni kunye nokuphambuka komgangatho kuphantsi;
I-6.Indawo yokunyibilika ephantsi (kufuphi ne-1300℃), kulula ukuyinyibilika kwi-inoculation processing, i-scum encinci.
Isicelo :
I-Ferro silicon strontium inoculant ilungele ukufakwa eludongeni olucekeceke okanye olupholileyo olumnandi lwesulfure inamandla e-inki eyomeleleyo, kodwa nebhola yentsimbi yokunyusa inani le-inki, ngakumbi ukunganyangeki kwe-nickel ductile iron (equlathe i-Ni14%, Cu6%, Cr2) %,Si 1.5%) ukongeza, njengoko kunciphisa umhlophe ngaphandle kokwandisa kakhulu inani le-eutectic, ngakumbi kwizicelo ezifuna ukuba akukho ukuphosa okuxineneyo, ukumelana noxinzelelo lwamanzi olungwevu lube nesiphumo esihle, inki eyomeleleyo kunye ne-carbon Si-Ca etyhidiweyo. isitofu esivumelekileyo sobushushu siphantsi .kwaye i-calcium , ubungakanani be-aluminiyam buphantsi , intsalela emile okwentsalela , akukho ziphene zokufunxa.
