Cov roj carbon ferriachrome (LCFECR) yog cov hlau-chromium alloy nrog cov yam ntxwv ntawm lub cev uas ua rau nws tseem ceeb hauv cov ntawv thov metallurgical. Hauv qab no yog nws cov khoom tseem ceeb ntawm lub cev:
1. Cov Khoom Siv Neeg Kho Tshuab
Ceev: ~ 7.1-7.3 G /M³ (me ntsis siab me ntsis dua li cov hlau ntshiab).
Melting taw tes: 1,500-1,550 degree, Ua rau nws haum rau cov txheej txheem kub-cov txheej txheem zoo li steelmaking steelmaking.
Kev nyuaj: Nruab hardness vim yog chromium cov ntsiab lus, tab sis tseem du ntxiv rau kev ua.
Kev ua siab loj: Cov khoom pov thawj zoo mallability thiab tuaj yeem dov lossis tau muab tso rau hauv cov ntawv txheeb lossis billets.
2. Thermal Khoom
Thermal conductivity: Siab thermal conductivity (~ 25-30 w / min k), pab cov cua sov dissipation hauv alloys.
Thermal nthuav tawm coefficiention: ~ 12-14 × 10⁻⁶ / degree (zoo ib yam li stainless hlau), ua kom muaj zog ruaj khov nyob rau hauv qhov kev hloov pauv.
Kev kub siab ruaj khov: Tsis kam oxidation thiab scaling ntawm nce qhov kub (tseem ceeb rau cov cub hluav taws xob lossis cov hlau qib siab).
3. Cov Khoom Siv Hluav Taws Xob
Hluav Taws Xob Kev Tshaj Tawm: Muaj hluav taws xob daws teeb meem, qis dua cov hlau ntshiab tab sis txaus rau cov laj thawj.
4. Cov yam ntxwv saum npoo
Oxidation tsis kam: Siv cov txheej txheem khib nyiab chromium (croo₃) thaum raug cua, tiv thaiv ntxiv corrosion.
Luster: Nws yog xim hlau nyiaj-grey tsos nrog ib tug du nto thaum ua tiav.
5. Cov Khoom Sib Nqus
Ferromagnetic: Khaws cov khoom sib nqus hauv qab no nws txoj kev ntsuas kub curse (~ 750 degree), tseem ceeb hauv kev siv hlau nplaum.
6. Thermal ruaj khov
Khaws cov txheej txheem kev ntseeg siab hauv qab cua sov / cua txias Cycles, txo cov kev phom sij lossis tawg rau hauv kev tsim cov hlau.
