The Future of Advanced Cupola Design

Key Strengths of Advanced Cupola Design

1. Continuous Melting

• Efficiency: The cupola design enables continuous melting, significantly enhancing production rates and overall efficiency.
• Cost-Effectiveness: This continuous process reduces operational costs by minimizing downtime and maximizing output.

2. High Flexibility

• Versatile Melting: Capable of melting scrap contaminated with plastics, grease, dirt, or slag, and handling large amounts of galvanized scrap.
• Variable Melt Rate: The melt rate can be adjusted by up to +/- 35%, allowing for precise control over the melting process.
• Diverse Iron Grades: Supports the production of grey iron, ductile iron, compacted graphite iron, and malleable iron.

3. Low Emissions

• Emission Reduction: Designed to minimize dust, heavy metals, and carbon dioxide emissions, meeting stringent environmental standards.
• Compliance: Emissions are well below permitted limits set by authorities in the US, Japan, Brazil, and the EU.

Cupola Melting Plant Technology

Storage and Batching

• Accurate Batching: Utilizes state-of-the-art weighing technology and automatic corrections to ensure precise batching and consistent iron chemistry.
• Efficient Charging: A smooth process with little fluctuations, essential for high-quality melting.

Cupola Furnace Design

• Center Charging: Ensures even distribution of the charge, maintaining a smoke-free furnace head and improving overall efficiency.
• Hot Blast Generation: Cold blast air is heated by flue gases, saving coke and silicon, and achieving higher iron temperatures and carbon pick-up.

Iron and Slag Handling

• Innovative Slag Management: Dry and wet slag granulation options, both environmentally friendly and efficient.
• Iron Storage: Holding furnaces ensure excellent temperature and chemistry control, enhancing the quality of the final product.

Emission Control and Energy Recovery

Emission Control

• Top Gas Management: Combustion of top gas results in low particulate emissions, with the option of wet gas cleaning systems for clean fuel gas export.
• Longevity: Low sulfur and NOx emissions extend the lifespan of recuperators.

Heat Recovery

• Energy Utilization: Excess energy from top gas combustion is harnessed through hot water, steam, or thermal oil systems, improving overall energy efficiency.

Automation Technology

The advanced cupola design incorporates cutting-edge process automation and control systems. The industrial Information Management System (iIM) bridges the gap between production and office operations, offering reliable and sophisticated operational data for better decision-making.
