Cov ntawv thov tseem ceeb thoob plaws kev lag luam
1. Steelmaking 🏗️
Calcium silicon lit ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau cov hlau huv si, tshwj xeeb tshaj yog nyob rau hauv kev siv tsheb, kev tsim kho, thiab ib qho.
Cov txiaj ntsig hauv kev siv hlau:
Deoxidation: tshem tawm cov pa oxygen los tiv thaiv porosity thiab kev tawg
Desulfurization: Tshem cov leej faj los txhim kho kev nce qib thiab txo cov brittleness
Kev tswj hwm: hloov kho cov kev cuam tshuam rau cov duab sib npaug rau cov tshuab raj zoo dua
Nws feem ntau siv thaum pw ua kom zoo dua thiab theem nrab metallurgy, kom muaj kev coj dawb huv, ua kom muaj kev sib dhos hauv cov khoom kawg.
2. HLAU COACTING 🧱
Nyob rau hauv lub foundry kev lag luam, calcium silicon lump yog dav siv raws li nodulizer thiab inoculant hauv du casting thiab grey hlau casting.
Nws cov txiaj ntsig:
Txhawb nqa graphite spheroidization, txhim kho kev nruj thiab yoog raws
Txhim khu fluhanced ntawm molten hlau
Txo shrinkage thiab burinholes nyob rau hauv castings
Qhov zoo tagnrho rau:
Automotive Qhov Chaw
Kav dej thiab li qub
Hnyav Cov Tshuab Cheebtsam hnyav
3. Ferrroalloy Ntau Lawm 🔧
Cov chaw tsim khoom ntawm ntau yam ferroalloys siv calcium sicicon lit ua lub hauv paus alloy lossis muab cov neeg sawv cev rov qab, tshwj xeeb hauv cov alloys zoo li:
Calcium aluminium
Calcium manganese
Calcium Barium Barium silicon
Nws lub siab reactivity thiab muaj peev xwm los cuam tshuam nrog ntau cov ntsiab lus ua rau nws muaj ntau yam nyob rau hauv alloy engineering.
