I. Description of VD/VOD Furnace
VOD (Vacuum Oxygen Decarburization) and VD (Vacuum Degassing) furnaces are advanced secondary refining units positioned after LF and before continuous casting in the EAF–LF–VD/VOD–CCM production route. They are essential for producing ultra-low carbon, low-gas, and high-purity steels by refining molten steel under vacuum conditions.
II. Typical Applications
-VD Furnace Applications:
High-quality carbon steel
Alloy steel and low-alloy steel
Bearing steel and clean steel grades
Steel grades requiring low hydrogen and nitrogen content
-VOD Furnace Applications:
Stainless steel
Ultra-low carbon stainless steel
High-alloy and corrosion-resistant steels
These systems are indispensable for steel producers targeting high-performance and demanding end-use applications.
III. Technical Features
High-Efficiency Vacuum System
Multi-stage vacuum pumping units ensure rapid pressure reduction and stable vacuum levels, enhancing degassing and decarburization efficiency.
Optimized Oxygen Blowing (VOD)
Precisely controlled oxygen injection promotes carbon removal while protecting chromium and other alloying elements from excessive oxidation.
Argon Stirring & Bath Homogenization
Inert gas stirring accelerates mass transfer, improves temperature and composition uniformity, and supports inclusion removal.
Robust Vacuum Vessel & Sealing Design
The furnace vessel and sealing systems are engineered to withstand repeated thermal and pressure cycling, ensuring long-term reliability.
Integrated Automation & Process Control
PLC-based systems monitor vacuum level, oxygen flow, temperature, and chemistry in real time, enabling stable and repeatable refining results.
