Oxide suppression type aluminum melting holding furnace [SMH series]
Reduces the occurrence of oxides and significantly decreases the hassle of cleaning the retention chamber. (About once every six months to a year!)
Oxide Suppression Furnace: SMH Series (Aluminum Holding Melting Furnace / Aluminum Central Melting Furnace) 【Features】 ◇ Maintains a low atmosphere temperature in the holding chamber (below 800°C) and keeps the residual oxygen concentration below 1%, utilizing the protective effect of the aluminum oxide film to slow down the progression of oxidation with a new concept furnace structure. ◇ Equipped with a newly developed flat frame burner to avoid directly applying flames to the molten metal in the holding chamber, preventing surface agitation, and implementing energy-saving measures through a heat exchanger that utilizes exhaust gas (a hybrid version with electric heaters is also available). ◇ To achieve significant forced convection heat transfer through matching the furnace structure, it is equipped with a newly developed melting burner that considers flame length, diameter, and speed. 【Expected Effects】 (Compared to our conventional furnaces) By using the oxide suppression furnace... ○ Reduction in the frequency of cleaning the holding chamber (proven to be unnecessary for up to one year) ○ Elimination of flux treatment (may be performed in the melting chamber depending on dross volume) ○ Improvement in molten metal quality (reduction of hydrogen gas and inclusions in the molten metal) ○ Increased yield due to reduced material loss ○ Improved fuel efficiency through energy recovery from exhaust heat in the holding chamber ○ Improved working environment due to reduced furnace surface temperature

Conducting aluminum melting tests using a hydrogen gas burner! (March 2024)
At Seiying 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 "aluminum molten quality" with those of an LPG combustion gas burner that was conducted beforehand. We will continue to analyze the detailed test results. For more details about this test furnace, please refer to the attached materials. Feel free to contact us regarding the implementation of the tests.

Developed a carbon-neutral aluminum melting holding furnace [Published in the Iron and Steel News, October 23, 2023, Page 5]
"Carbon Neutral Aluminum Melting Holding Furnace Developed by Shoei Manufacturing Co., Ltd." Published in "Steel News, 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 those for 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 thermal source configuration that enables carbon neutrality through "hydrogen × green electricity" has been achieved. 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 uncertainties regarding future energy supply, we will contribute to the decarbonization of the manufacturing industry by applying the combustion technology and hybridization technology for thermal sources that we have cultivated so far.
