Strontium-Silicon (SrSi)
Dzina la malonda:Ferro silicon strontium inoculant (SrSi)
Chitsanzo/Kukula:0-10mm; 5-25mm/10-50mm/0.2-0.7mm/1-6mm
Tsatanetsatane wa Zamalonda:
Ferro silicon strontium nucleating agent ndi mtundu wa FeSi-based alloy yomwe ili ndi kuchuluka kwa barium ndi calcium, imatha kuchepetsa kuzizira, kutulutsa zotsalira zochepa.Choncho, Ferro silicon barium inoculant ndi yothandiza kwambiri kuposa inoculant yomwe imakhala ndi calcium yokha, kuwonjezera apo, imakhala ndi ntchito yofanana ndi yomwe inoculant yokhala ndi barium ndi calcium yapamwamba ingakhale nayo.Kuphatikizika kwa barium ndi kashiamu kumawongolera bwino kuzizira kusiyana ndi inoculant yokhala ndi calcium yokha.
Ferro silikoni strontium makamaka ntchito ngati kuponyera inoculant, strontium mu ferrosilicon inoculant ndi imodzi mwa zinthu zolimbikitsira kwambiri, pamene lalikulu undercooling digiri, strontiuim ali ndi ntchito yapadera .kuchepetsa chiwerengero cha eutectic gulu akhoza kuchepetsa shrinkage, shrinkage zofooka za kuponyera.
China golide wogulitsa zinthu zatsopano FeSiSr
Zofunika Kwambiri :
(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% |
Magwiridwe ndi mawonekedwe:
1. Kuwonjezeka kwakukulu kwa graphitization pachimake, kuyenga graphite, kulimbikitsa mtundu wa A-graphite mu chitsulo chotuwa ndi graphite yomwe imakhala yozungulira muzitsulo zachitsulo, kusintha mlingo wa spheroidizing;
2. Kuchepetsa kwambiri kuzizira, kuchepetsa kuuma kwachibale, kuwongolera magwiridwe antchito;
3. Mphamvu yolimba yolimbana ndi kugwa kwachuma, kupewa kulowetsedwa ndi kutsika kwachuma;
4. Kupititsa patsogolo homogeneity ya fracture pamwamba, kuchepetsa chizolowezi chochepa;
5. Khola mankhwala zikuchokera, homogeneous tinthu kukula, kupatuka zikuchokera ndi khalidwe kupatuka ndi otsika;
6.Low melting point (pafupi ndi 1300 ℃), yosavuta kusungunuka mu inoculation processing, scum pang'ono.
Ntchito :
Ferro silikoni strontium inoculant oyenera woonda-mipanda kapena ozizira lokoma phulusa sulfure kuponyedwa ali ndi mphamvu inki luso, komanso ductile chitsulo mpira kuonjezera chiwerengero cha inki, makamaka mkulu dzimbiri kukana wa faifi tambala ductile chitsulo (muli Ni14%,Cu6%,Cr2) %,Si 1.5%) kuwonjezera, popeza amachepetsa woyera popanda kwambiri kuwonjezera chiwerengero cha eutectic, makamaka ntchito zimene amafuna palibe kuponyera wandiweyani lotayirira, madzi kuthamanga kukana imvi kuponyedwa bwino, inki wamphamvu ndi mpweya Si-Ca wosungunuka. inoculant kutentha kovomerezeka ndi kotsika .ndi calcium , kuchuluka kwa aluminiyamu ndi kochepa, zotsalira zosaoneka bwino, palibe vuto loponyera vacuum.
