Security Design AOD Furnace with Intellectualized Smelting Process and Secondary Combustion Top Lance for Ladle Refining
The AOD (Argon Oxygen Decarburization) Furnace is a specialized Ladle Refining Furnace with capacity ranging from 3T to 120T. This advanced system features side-blown oxygen through bottom tuyeres using an immersion method for efficient refining operations.
Key Operational Features
Precision gas mixing system for oxygen, argon, and nitrogen through tuyere center
Adjustable gas proportions for optimal decarburization while retaining chromium
Tuyere ring cooling system using argon and nitrogen to extend equipment lifespan
Comprehensive flow control for both tuyere center and ring from master control room
Special online temperature measuring system to monitor molten steel conditions
Secondary combustion top lance technology for increased efficiency
Computer-controlled weighing system with multiple bunkers for precise material addition
Process Advantages
Our intelligent smelting process control system significantly reduces raw material and gas consumption while ensuring consistent product quality. The technology enables:
Increased cold material volume in VOD operations
Reduced smelting duration
Support for continuous casting across multiple furnaces
Lower labor intensity through automation
Enhanced Safety Design
The AOD series incorporates specialized safety features to address critical operational risks:
Prevents lance plugging and molten steel backflow during power interruptions
Maintains tuyere pressure stability during operations
Uninterruptible power supply integration for critical safety functions
These advanced safety measures significantly improve the reliability and security of the smelting process.
