Core Technical Advantages
RBSC crucibles outperform pa alumina thiab graphite counterparts los ntawm:
- Tshwj xeeb thermal conductivity (120-150 W / m·K ntawm 1000 ° C)
- Ultra-low thermal expansion coefficient (4.5 × 10⁻⁶ / K)
- Thermal shock resistance withstanding 50+ ceev cua txias voj voog (1600 ° C → 25 ° C)
- Acid / alkali corrosion kuj (pH 0-14 compatibility)
- Oxidation stability nyob rau hauv huab cua mus txog 1650 ° C
Metallurgical Mastery
Nyob rau hauv alloy steel ntau lawm thiab cov hlau tsis-ferrous smelting (txhuas, tooj liab, zinc), RBSC crucibles pab:
- 20-30% sai melting tus nqi los ntawm optimized hloov tshav kub
- 99.95% hlau purity txij nkawm ntawm cov khoom tsis-reactive
- Txo cov slag tsim los ntawm minimized thermal stratification
- Kev pab lub neej ntev (3-5 × ntev dua av nplaum-graphite crucibles)
Precision Casting & Mechanical Applications
Lub crucibles 'cov khoom siv tshwj xeeb txhawb kev xav tau kev lag luam:
- Kev ruaj ntseg ntawm cov qauv hauv qab 15-20 MPa cov neeg kho tshuab kev ntxhov siab
- Kev ruaj ntseg zoo ib yam (± 0.1% kev hloov pauv ntawm 1500 ° C)
- Kev ua kom tsis muaj paug paug rau aerospace-qib Cheebtsam
- Txhim khu kev ua tau zoo hauv centrifugal casting tshuab
Chemical Processing Excellence
RBSC crucibles daws cov teeb meem tseem ceeb hauv kev tsim tshuaj lom neeg:
- Muaj kev nyab xeeb ntawm cov ntsev ntsev (xws li NaOH, KNO₃)
- Kev ua haujlwm ruaj khov hauv sulfidation / chlorination cov tshuaj tiv thaiv
- Corrosion tiv thaiv HF txog 800 ° C
- Purity preservation nyob rau hauv tsawg lub ntiaj teb lub ntsiab extraction
Kev Lag Luam Kev Lag Luam
Thaum cov nqi pib yog 40-60% siab dua li ib txwm crucibles, RBSC cov kev daws teeb meem xa:
- 70% txo qhov hloov zaus
- 25-35% kev txuag hluav taws xob los ntawm kev txhim kho thermal efficiency
- 90% cov khoom siv rov ua dua tshiab ntawm thermal reclamation
- Zero tu yuav tsum
