Technical Specifications

The performance of Ferro-Carbon Balls is defined by their precise chemical composition, which ensures optimal functionality in BOF operations. Below is a detailed breakdown of the product's technical parameters:

Component	Specification
Iron (Fe%)	≥40%
Carbon (C%)	≥25%
Silicon Dioxide (SiO₂%)	≤10%
Sulfur (S%)	≤0.4%
Phosphorus (P%)	≤0.1%
Customization	Available upon request

The high iron and carbon content of these balls ensures efficient energy transfer during the BOF process, while the low levels of impurities like sulfur and phosphorus contribute to the production of clean steel, as noted in metallurgical standards. According to the National Institute of Standards and Technology (NIST), such precision in material composition is critical for achieving consistent quality in industrial applications.

Usage and Application

The correct application of Ferro-Carbon Balls is essential to maximize their benefits in BOF operations. The following guidelines outline the recommended procedure:

1. Material Loading: Begin by loading molten iron and scrap as per standard practice.
2. Ball Addition: Introduce the ferro-carbon balls into the converter after scrap loading but before the start of the blowing process. The total amount should not be less than 15 kg per ton, with 2-3 kg added per batch based on temperature and slag melting conditions.
3. Additional Materials: Other bulk materials should be added according to conventional methods.
4. Optimization: Monitor performance during experiments and adjust the loading time and quantity of ferro-carbon balls based on the converter’s operational status.

Key Advantages

Ferro-Carbon Balls offer several distinct advantages that make them a preferred choice in modern steelmaking:

• Temperature Enhancement: Adding 1 kg of ferro-carbon balls per ton of steel can increase the end-point temperature of the BOF by approximately 1.4°C, reducing the need for additional energy inputs.
• Cost Efficiency: The use of these balls can lower steel material consumption by about 1.2 kg per ton, directly contributing to operational cost savings.
• Purity Improvement: The low trace element content in the balls minimizes contamination, enabling the production of clean steel that meets stringent quality requirements.
• Environmental Benefits: By reducing material waste and energy consumption, Ferro-Carbon Balls support sustainable steelmaking practices, aligning with global efforts to minimize industrial carbon footprints.
