Product Description
Electroslag Refining Furnace (ESR) Overview
The Electroslag Refining Furnace (ESR) is a specialized smelting system designed for producing high-quality special alloy steels. This advanced equipment utilizes resistance heat generated by current passing through a slag pool to melt consumable electrodes, resulting in superior metal purification and crystalline structure.
ESR Technology & Process
Electroslag remelting employs resistance heat from current passing through slag as the primary heat source. This method achieves comprehensive metal purification and produces steel ingots with uniform, dense crystalline structures.
Key Metallurgical Functions
- Heating: Efficient thermal energy generation through electrical resistance
- Refining: Comprehensive purification and inclusion removal
- Sequential Crystallization: Controlled solidification for optimal microstructure
Product Advantages
- High purity steel with extremely low sulfur content
- Fine dispersion of non-metallic inclusions
- Smooth ingot surface with uniform, dense crystallization
- Elimination of white spots and annual ring segregation
- Consistent microstructure and chemical composition
- As-cast mechanical properties matching or exceeding forged steel standards
Applications & Industries
ESR technology dominates large and medium-sized forging production, module blank manufacturing, and specialized applications including tool steel, maraging steel, dual-phase steel billets, and cold rolling rolls. Electroslag melting also enables unique casting of shaped components, with annual production reaching hundreds of thousands of tons in China.
Configuration Types
Available in multiple configurations based on support arm and ingot car design:
- Single-arm single ingot model
- Single-arm double ingot model
- Double-arm ingot alternating type
- Double-arm rotating alternating fixed type
- Double-arm rotating alternating pumping type
