Long Service Life VD/VOD Furnace with Mechanical Vacuum Pump for Manufacturing Plant

Product Description

(VD/VOD) Vacuum Oxygen Decarburization Furnace Ladle Refining Furnace

Available in 50 Ton, 100 Ton, and 150 Ton capacities with Mechanical Vacuum Pump for Manufacturing Plants and Spare Parts.

Advanced Secondary Vacuum Refining Technology

The metallurgical industry has evolved from quantitative production 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 Process
VOD - Vacuum Oxygen Decarburization Ladle Refining Process

Process Advantages

The VD/VOD process combines optimal argon stirring from furnace bottom with vacuum conditions to achieve:

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 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

1. 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
Argon stirring efficiency

2. Denitrification

While nitrogen removal is challenging due to alloy content relationships, our process:

Minimizes pre-treatment nitrogen levels
Extends VD treatment duration
Leverages hydrogen-nitrogen partial pressure relationships

3. Desulfurization

Integrated with deoxidation processes, with enhanced capabilities through:

Strategic use of sulfur-affinity elements
Optimized oxygen-sulfur balance

4. Argon Stirring System

Our precision-controlled system features:

Independent argon flow adjustment per vacuum tank
Mass flow control modules for precise regulation
Enhanced molten steel circulation for optimal reaction conditions
