High-frequency induction furnace F-MELT100G that achieves energy saving for electric furnaces.

basic information

Over 2,500 units of induction furnaces have been introduced. Based on this extensive track record, we have combined our "power electronics technology," "high-voltage insulation technology," and "analysis technology" to create the high-frequency induction furnace F-MELT100G. To address energy conservation, high efficiency, and large capacity needs, the F-MELT100G series is equipped with a high-efficiency furnace body that improves melting unit consumption and a high-voltage IGBT stack. It not only enhances energy efficiency but also evolves reliability and safety, achieving high performance that is unmatched by others. Additionally, by adopting a direct digital control unit equipped with self-check functions and RAS (Reliability, Availability, Serviceability) features, we have made it possible to stabilize equipment operation and reduce the time required to identify causes in the event of a failure. These technologies promote energy savings in electric furnaces, advance carbon neutrality in foundries, and improve productivity and stability.

Applications/Examples of results

■Energy Saving and CO2 Reduction Case Study (Akakane Iron Works Co., Ltd.) Realization of energy saving and CO2 reduction through the transition from cupola to electric furnace/high-frequency induction furnace [Customer Feedback] - "The fact that they have the top market share in the industry and were able to introduce the latest electric furnace was great. It was also good that the supply of maintenance parts is stable. By switching to the electric furnace, we can reduce CO2 emissions and improve quality, which leads to a lower environmental impact and enhanced safety." *Excerpt from customer interview in the introduction case study video [Products and Systems Introduced] - High-frequency induction furnace (F-MELT100G) Furnace monitoring system [Challenges Before Introduction] - Building a manufacturing system aimed at decarbonization and green growth strategy; achieving energy saving and CO2 reduction [Benefits of Introduction] - Reduction of environmental impact, improvement in quality and safety, stabilization of maintenance parts supply

Detailed information

• 

  ■Improving melting efficiency with 3D structure and magnetic field analysis technology, achieving energy savings in electric furnaces. In foundries, it is necessary to further promote energy savings and carbon neutrality in response to decarbonization efforts. F-MELT100G is a high-efficiency electric furnace/high-frequency induction furnace. We have consolidated our technologies to reduce the power consumption per unit of output.

• 

  ■ Streamlining maintenance work through space-saving design of the panel and reduced coil replacement time. To stabilize factory operations, both preventive and corrective measures, including maintenance activities and reducing downtime during failures, are required for efficiency. The F-MELT100G enables work efficiency through space-saving design of the power panel, reduced coil replacement time, and self-fault diagnosis functions.

• 

  ■Real-time understanding of operational status enables preventive maintenance and optimal operation. In recent years, efforts to reduce dependence on individuals through the use of IoT have been progressing. This is due to the anticipated shortage of personnel caused by the retirement of highly skilled engineers. The F-MELT100G adopts IoT and digital technologies, making it possible to visualize operations and streamline and standardize fault diagnosis and deterioration assessment.
