CaSi (Calcium Silicon) alloy hmoovyog crushed granular metallurgical khoom ua los ntawmcalcium silicon alloy lumps. Nws yog ib qho kev ua haujlwm siab -kev ua tau zoo sib xyaw metallurgical additive lug siv nyob rau hauv niaj hnub steelmaking thiab foundry industries. Piv nrog rau ib qho deoxidizers xws li ntshiab silicon los yog txhuas, CaSi alloy hmoov muab cov calcium thiab silicon hloov kho ob qho tib si, xa cov deoxidation ruaj khov, desulfurization, thiab kev tswj xyuas.
Cov txheej txheem kev lag luam muaj 28-32% Calcium thiab 60-65% Silicon, nrog nruj tswj tsis muaj leej faj thiab phosphorus impurities. Nws muaj nyob rau hauv customized ntau thiab tsawg rau ladle refining, furnace deoxidation, thiab casting inoculation processes.Muaj steel mills thiab foundries upgrade lawv cov txheej txheem smelting los ntawm kev hloov ib txwm additives nrog Calcium Silicon hmoov los txo qhov tsis xws luag casting, txhim kho steel purity, thiab txo tag nrho cov nqi ntau lawm.
Core Technical & Production Benefits of CaSi Alloy Powder
CaSi alloy hmoov ua tau zoo ib qho txhuas deoxidizer,ferrosilicon, thiab calcium -raws li additives nyob rau hauv ntau qhov ntev. Cov txiaj ntsig hauv qab no tau txheeb xyuas hauv kev tsim cov hlau loj thiab casting ntau lawm.
Hwj chim Composite Deoxidation & Desulfurization
Calcium thiab silicon ua haujlwm ua ke kom tshem tawm cov pa oxygen thiab leej faj nyob rau hauv molten steel thiab molten hlau. Silicon ua tiav thawj deoxidation, thaum calcium ntxiv tshem tawm cov pa oxygen sib sib zog nqus thiab ua kom ruaj khov qis - melting - cov ntsiab lus suav nrog. Qhov no txo qis oxide thiab sulfide impurities thiab txhim kho molten hlau huv si.
Inclusion Modification & Nozzle Clogging Prevention
Kev lig kev cai txhuas deoxidation ua rau nyuaj, ntse alumina inclusions uas yooj yim thaiv nruam casting nozzles. CaSi hmoov hloov rigid alumina inclusions mus rau hauv mos, spherical calcium aluminate inclusions. Cov kev sib txuas ua ke no ntab tau yooj yim thiab tsis sib sau rau ntawm phab ntsa nozzle, zoo heev txhim kho kev txuas ntxiv mus.
Txhim kho Mechanical Properties ntawm Finished Steel
Los ntawm purifying molten steel thiab refining grain qauv, SiCa alloy hmoov zoo txhim kho steel toughness, ductility, qaug zog tsis kam, thiab cuam tshuam kev ua tau zoo. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog rau qib siab -kawg steel xws li pipeline steel, nkoj steel, thiab qis- alloy siab- lub zog steel.
Txo Casting Defects hauv Foundry Production
Hauv cov hlau grey thiab cov hlau nplaum ntau lawm, Silicon Calcium hmoov ua raws li kev ua haujlwm zoo. Nws refines graphite qauv, zam undercooled graphite, txhim kho molten hlau fluidity, thiab txo cov kev tsis xws luag xws li porosity, shrinkage kab noj hniav, thiab txias kaw.
CaSi Alloy Powder vs. Traditional Additives
