正英製作所 Company Profile

Seihei Seisakusho, a manufacturer of gas burners and industrial furnaces, will participate in the Thermal Technology 2024 event, which consists of an exhibition of industrial furnaces and related equipment, as well as seminars and lectures, serving as an information dissemination event from the Kansai region. We will propose decarbonization/low-carbon items for production equipment, including: - Low-carbon painting and drying equipment - Hydrogen × electric hybrid aluminum melting and holding furnace - Hydrogen gas burners Additionally, we will be well-prepared to introduce energy-saving burners and furnaces equipped with them.

At Seiei Manufacturing, we are working on the development of aluminum industrial furnaces that can contribute to achieving carbon neutrality and a decarbonized society. Recently, we conducted aluminum melting tests using hydrogen gas burners in collaboration with customers aiming for carbon-neutral manufacturing. For the test furnace, we adopted the "SMH type" melting holding furnace, which generates extremely low amounts of oxides. The heat source consisted of a hydrogen-exclusive gas burner "EIS-H2" for melting and an electric heater for holding the molten aluminum, creating a hybrid configuration. In this melting test, we compared the "melting speed" and "quality of molten aluminum" with those of a previously conducted LPG combustion gas burner. We will continue to analyze the detailed test results. Please refer to the attached document for more details about this test furnace. Feel free to contact us regarding the implementation of the tests.

"Carbon Neutral Aluminum Melting Holding Furnace Developed by Shoei Manufacturing Co., Ltd." Published in the "Iron and Steel Newspaper, October 23, 2023, Page 5." Shoei Manufacturing Co., Ltd. (Headquarters: Hirano Ward, Osaka City, Representative: Shota Habaki), a specialized manufacturer of industrial gas burners and industrial furnaces, has developed an aluminum melting holding furnace that enables decarbonization in aluminum casting sites such as automotive parts. A new hydrogen gas burner that emits no CO2 during combustion has been adopted for the melting line. By placing high-efficiency immersion heaters in the holding line for the molten aluminum melted by hydrogen combustion, a heat source configuration that achieves carbon neutrality through "hydrogen × green electricity" has been realized. A test furnace based on actual equipment has been newly established at the Thermal Technology Research Institute. We are accepting visits to observe hydrogen combustion and tests for actual aluminum melting. Amid uncertain prospects for future energy supply, we will contribute to the decarbonization of the manufacturing industry by applying the combustion technology and hybridization technology for heat sources that we have cultivated so far.
