Product Overview
Oxygen is a critical process gas in modern steelmaking. It directly influences:
- Furnace temperature stability
- Carbon removal efficiency
- Energy consumption per ton of steel
- Overall production output
Traditional oxygen supply methods such as liquid oxygen delivery or cylinder supply are increasingly inefficient and costly for large-scale steel operations.
Our Solution
We design and manufacture on-site oxygen generation plants specifically engineered for steel mills, enabling:
- Continuous 24/7 oxygen supply
- Independent gas production at steel plant site
- Significant reduction in oxygen procurement cost
- Stable integration with BF / BOF / EAF systems
Our systems are designed for continuous heavy-duty industrial operation, not laboratory or small commercial use.
