Ukuhlanza Insimbi Encibilikisiwe Ukwenza insimbi I-Metallurgy Ingxubevange Ingxubevange Yengxubevange Umhlinzeki weSilicon Ingxubevange yeCalcium Calcium Silicon Alloy

I-alloy kanambambili eyakhiwe nge-silicon ne-calcium ingeyesigaba sama-ferroalloys. Izingxenye zayo eziyinhloko ziyi-silicon ne-calcium, futhi iqukethe nokungcola okunjengensimbi, i-aluminium, i-carbon, isulfure ne-phosphorus ngamanani ahlukahlukene. Embonini yensimbi nensimbi, isetshenziswa njengesengezo se-calcium, i-deoxidizer, i-desulfurizer kanye ne-denaturant ye-non-metallic inclusions. Isetshenziswa njenge-inoculant kanye ne-denaturant embonini ye-cast iron. Ngesisekelo se-silicon-calcium alloy, ezinye izakhi zengezwa ukuze zenze i-ternary noma i-multi-element composite alloy. NjengeSi-Ca-Al; Si-Ca-Mn; I-Si-Ca-Ba, njll., isetshenziswa njenge-deoxidizer, i-desulfurizer, i-ejenti ye-denitrification kanye ne-alloying ejenti kunsimbi nensimbi.

I-calcium iyinsimbi yomhlaba ene-alkaline enesisindo se-athomu esingu-40.08, isakhiwo se-electronic sangaphandle esingu-4S2, ukuminyana (20°C) kuka-1.55g/cm3, indawo yokuncibilika engu-839±2°C, kanye nephuzu elibilayo elingu-1484° C. Ubudlelwano phakathi komfutho we-vapor we-calcium nezinga lokushisa buyi

lnpCa=25.7691-20283.9T-1-1.0216lnT

Lapho i-pCa ingumfutho we-vapor we-calcium, i-Pa; I-T izinga lokushisa, i-K. Silicon ne-calcium yakha izinhlanganisela ezintathu, okuyi-CaSi, i-Ca2Si ne-CaSi2. I-CaSi (41.2% Si) izinzile emazingeni okushisa aphezulu. I-Ca2Si (29.5%Si) iyinhlanganisela ye-peritectic eyakhiwe phakathi kwe-Ca ne-CaSi emazingeni okushisa angaphansi kuka-910°C. I-CaSi2 (58.36%Si) iyinhlanganisela ye-peritectic eyakhiwe phakathi kwe-CaSi ne-Si emazingeni okushisa angaphansi kuka-1020°C. Ukwakhiwa kwesigaba sama-alloys e-silicon-calcium akhiqizwa ezimbonini cishe ku-77% CaSi2, 5% kuya ku-15% CaSi, i-Si <20% yamahhala, ne-SiC <8%. Ukuminyana kwe-silicon-calcium alloy equkethe u-30% kuya ku-33% we-Ca futhi cishe u-5% we-Fe cishe u-2.2g/cm3, futhi izinga lokushisa elincibilikayo lisukela ku-980 kuya ku-1200°C.
