Molten Metal Degassing System

Product Specifications

Technical details and manufacturing context for Molten Metal Degassing System

Definition

The Molten Metal Degassing System is an industrial system used in basic metal manufacturing to remove dissolved hydrogen, oxygen, and nitrogen from molten aluminum, steel, and other non-ferrous metals. It integrates gas injection, mixing, and separation components to reduce porosity and inclusions, thereby improving metal quality. The system operates continuously within casting and melting lines to ensure consistent metal purity and mechanical properties in final products. Key components include a stainless steel housing, refractory lining, graphite rotors, ceramic components, and copper electrical contacts. The system is designed for treatment capacities ranging from 500 to 5000 tons per hour, with inert gas flow rates of 5 to 50 liters per minute, rotor speeds of 200 to 600 RPM, and power consumption of 5 to 15 kW. Operating temperatures range from 680 to 760°C, and gas supply pressure is 0.4 to 0.6 MPa. The rotor material is high-purity graphite. Heating power for maintaining melt temperature is 30 to 60 kW, and control voltage is 220 to 480 V AC (3-phase). The protection class is IP54 per IEC 60529, with a weight of 800 to 2000 kg and a footprint of 2 to 4 square meters. These values are reference ranges and must be verified for the specific model and application. The system is not certified or compliant solely based on listed standards; verification with the legal manufacturer or supplier is required. The working principle involves injecting inert gas (argon or nitrogen) into the molten metal through rotating impellers or porous plugs, creating bubbles that absorb dissolved gases via diffusion and carry them to the surface for removal. This process is critical for producing high-quality metal castings. For selection, consider metal type, treatment capacity, and existing line integration. Interfaces include gas supply, electrical connections, and control systems. Verification questions should address actual performance under specific conditions. Maintenance signals include reduced degassing efficiency, increased gas consumption, or abnormal rotor wear. Failure boundaries include exceeding maximum temperature or pressure, which may damage components.

Working Principle

Inert gas (argon or nitrogen) is injected into molten metal through rotating impellers or porous plugs. The gas forms bubbles that rise through the melt, absorbing dissolved gases (hydrogen, oxygen, nitrogen) via diffusion. The bubbles carry these gases to the surface, where they are released into the atmosphere. The rotating impellers enhance mixing and bubble dispersion, increasing the efficiency of gas removal. The system operates continuously to maintain metal purity.
