Conducting aluminum melting tests using a hydrogen gas burner! (March 2024)

A test furnace based on actual equipment, with dissolution using a hydrogen burner and retention using an electric heater. Thorough testing for decarbonization in aluminum casting sites can be conducted together with our customers!

It is possible to conduct aluminum melting tests using hydrogen combustion with ingot input. Please use it to verify the quality of the molten metal and its impact on the products. The melting gas burner employs a hydrogen burner and electric heaters for retention! It is a hybrid furnace that enables carbon neutrality. By exchanging burner parts, you can switch between fuel gases (hydrogen/LNG (natural gas)/LPG), allowing for adaptability to trends in gas supply. Additionally, the furnace structure has a high oxide suppression effect, so you can confirm this effect in actual operation. We are committed to solving problems in aluminum casting sites and promoting low carbon emissions. Please feel free to reach out to us. ~Equipment Overview~ Test Furnace: Aluminum Handheld Melting Retention Furnace (Oxide Suppression Structure) Model: SMH-150H2 Melting Capacity: 150 kg/h Retention Capacity: Retention Chamber 800 kg/ch *Actual effective capacity during continuous melting, specific gravity 2.4 Melting Temperature: 660–680℃ Control Accuracy: ±5℃ ~Heat Source Configuration~ Melting Burner: Hydrogen Combustion Burner 116 kW × 1 unit Retention Heater: Immersion Type Electric Heater 9 kW × 2 units Fuel Used: Hydrogen (city gas 13A and propane gas are also possible) Power Supply: 200V/60Hz for power, 100V for operation

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 (below 800°C) in the holding chamber and keeps the residual oxygen concentration below 1%, utilizing the protective effect of the aluminum oxide film to slow down the progress of oxidation with a new furnace structure. ◇ Equipped with a newly developed flat frame burner that prevents direct flame contact with the molten metal in the holding chamber, ensuring no disturbance to the surface of the molten metal. Additionally, energy-saving measures are implemented through a heat exchanger utilizing exhaust gas (a hybrid version with electric heaters is also available). ◇ To achieve significant forced convection heat transfer through matching the furnace structure, a newly developed melting burner is installed, taking into account 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 the amount of dross) ○ 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 waste heat in the holding chamber ○ Improved working environment due to reduced surface temperature of the furnace
