Product Description
VD/VOD Vacuum Oxygen Decarburization Furnace Overview
Advanced secondary vacuum refining furnace systems available in 50 Ton, 100 Ton, and 150 Ton capacities with mechanical vacuum pump technology for manufacturing plants and spare parts.
Advanced Secondary Vacuum Refining Technology
Modern metallurgical production has evolved from quantitative output to focus on variety diversification and high quality. Achieving super purity indices (total [H], [N], [O], [S], [P] ≤50ppm or lower) requires secondary vacuum refining techniques, primarily VD (Ladle Vacuum Refining) and VOD (Vacuum Oxygen Decarburization) processes.
Process Advantages
The VD/VOD process combines optimal argon stirring from furnace bottom with vacuum conditions to deliver:
- Effective dehydrogenation, denitrification, desulfurization, and deoxidation
- Superior molten steel purity through Vacuum Oxygen Decarburization (VOD)
- Cost-effective structure when combined with LF furnace
Vacuum Pump Systems
Our decade of research has produced two advanced vacuum pump systems:
| System Type | Working Medium | Advantages | Considerations |
|---|---|---|---|
| Full Steam Jet Vacuum Pump | Water steam + cooling water | Lower equipment cost | Higher steam consumption |
| Steam Jet + Water Ring Vacuum Pump | Reduced steam + cooling water + minimal electricity | Lower steam consumption | Higher equipment cost |
Both systems meet secondary vacuum refining requirements with comparable total investment costs.
Company Expertise
As China's leading manufacturer of vacuum refining equipment, we have:
- Designed and produced over 180 VD/VOD and RH vacuum refining systems
- Served more than 100 companies with reliable vacuum solutions
- Pioneered VD/VOD vacuum refining and VC vacuum casting equipment in China
VD Furnace Refining Process Details
Dehydrogenation
Achieves hydrogen content [H] ≤1.5ppm at vacuum ≤133Pa. Our system operates below 67Pa to ensure optimal dehydrogenation, accounting for process variables including steel grade specifications, raw material conditions, and argon stirring efficiency.
Denitrification
While nitrogen removal is challenging due to alloy content relationships, our process minimizes pre-treatment nitrogen levels, extends VD treatment duration, and leverages hydrogen-nitrogen partial pressure relationships.
Desulfurization
Integrated with deoxidation processes, with enhanced capabilities through strategic use of sulfur-affinity elements and optimized oxygen-sulfur balance.
Argon Stirring System
Our precision-controlled system features independent argon flow adjustment per vacuum tank, mass flow control modules for precise regulation, and enhanced molten steel circulation for optimal reaction conditions.
