Ukuhlanza Insimbi Encibilikisiwe Ukwenza insimbi I-Metallurgy Ingxubevange Ingxubevange Yengxubevange Umhlinzeki weSilicon Calcium Ingxubevange yeCalcium Silicon Alloy
sebenzisa
Njenge-compound deoxidizer (i-deoxidization, desulphurization and degassing) Isetshenziswa ekwenzeni insimbi, ukuncibilikisa ingxubevange.Njenge-inoculant, ibuye isetshenziswe ekukhiqizeni ukukhiqiza.
Isimo somzimba:
Ingxenye ye-ca-si impunga ngokukhanyayo evele inomumo wokusanhlamvu osobala.Isigaxa, okusanhlamvu kanye nempushana.
Iphakheji:
inkampani yethu inganikela ngezimo ezihlukahlukene ezishiwo okusanhlamvu ngokuvumelana nezidingo zabasebenzisi, ezipakishwe ngendwangu yepulasitiki kanye nesikhwama sethani.
Izakhiwo kanye nezinzuzo ze-ferrosilicon
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) okungu-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, kanye 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.
