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 components, you can switch between fuel gases (hydrogen/LNG (natural gas)/LPG), allowing for adaptability based on gas supply trends. Additionally, the furnace structure has a high oxide suppression effect, which you can verify in actual operation. We are committed to solving problems in aluminum casting sites and promoting low carbonization. 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: 150kg/h Retention Capacity: Retention Chamber 800kg/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 116kW x 1 unit Retention Heater: Immersion Type Electric Heater 9kW x 2 units Fuel Used: Hydrogen (city gas 13A and propane gas are also possible) Power Supply: 200V/60Hz for power, 100V for operation

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 furnace structure. ◇ Equipped with a newly developed flat frame burner to prevent agitation of the molten surface without directly applying flame to the molten metal in the holding chamber, and incorporates a heat exchanger utilizing exhaust gas for energy savings (a hybrid version using electric heaters is also available). ◇ To significantly enhance forced convection heat transfer from the matching of the furnace structure, it is equipped with a newly developed melting burner that considers flame length, flame diameter, and flame 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 1 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 reduction in material loss ○ Improved fuel efficiency through energy savings from waste heat recovery in the holding chamber ○ Improved working environment due to reduced furnace surface temperature

<Problems with Reflective Electric Heater Holding Furnaces> - The atmosphere temperature above the aluminum molten surface is high at 850°C, which promotes the generation of oxides. <Problems with Under-type Electric Heater Holding Furnaces> - Complete draining of the molten metal is necessary during heater tube replacement, which poses safety risks such as leaks. <Problems with Vertical Immersion Electric Heater Holding Furnaces> - The heater tubes are exposed above the molten surface, resulting in significant heat loss from the furnace body and a high occurrence of oxide generation around the tubes. ~These issues are resolved with the "Diagonal" Immersion Type!~ [What is a Diagonal Immersion Type Holding Furnace?] It is a holding furnace equipped with high-efficiency electric heaters installed diagonally downward towards the aluminum molten surface. 1. Reduction of Oxides - Similar to the under-immersion type, the immersion heater is completely submerged in the aluminum molten metal, which suppresses the generation of oxides. 2. Improved Maintainability - The immersion heater tube can be replaced by draining the molten metal down to the lower limit of the molten metal sensor. 3. Safety - Compared to the under-immersion type, there are fewer issues with aluminum molten metal leaks due to the heater's mounting position and structure. 4. Energy Saving - By adopting high-efficiency heaters, the heat loss from the furnace body in the ceiling area is reduced. Holding capacities range from 500kg to 2000kg.

The "Metal Knit Burner," ideal for mold heating, eliminates excess combustion air and achieves "gentle yet high-speed heating for molds" through the synergistic effect of heat flow and infrared. Unlike conventional torch gas burners, it does not produce unnecessary flames, improving the surrounding environment and achieving significant energy savings. In the casting of automotive parts, which requires strict quality control, we can quickly and evenly heat the necessary parts of each mold, leading to feedback such as "no need for waste shots." We have a wealth of experience both domestically and internationally. We can design according to the shape of the mold, so please feel free to consult with us. 【Features】 ■ Combustion set with safety device = can be combined with a pack mixer for quick on-site installation ■ Can be made into a mobile unit, allowing the burner set to be used only when needed ■ Uses heat-resistant alloy fibers * For more details, please refer to the PDF document or feel free to contact us.

The EIM burner is a gas burner of the nozzle mix type that produces a high-brightness, straight flame. It has a large turndown ratio, achieving stable combustion across the entire range of combustion volume. Stable combustion is obtained across the entire range of combustion volume, eliminating concerns about backfire in low combustion areas. In applications such as aluminum melting furnaces, the radiant heat from the high-brightness flame improves melting efficiency. You can choose a direct ignition method, which eliminates the need for a pilot burner, simplifying the piping system. It has a structure that is easy to disassemble and maintain. It achieves stable combustion at a low air ratio, minimizing excessive oxygen that can cause oxides and improving fuel efficiency. 【Features】 ■ Stable combustion is achieved ■ The flame is a high-brightness straight flame ■ The combustion system is simple ■ Easy to install ■ Maintenance and inspection are easy *For more details, please download the PDF or feel free to contact us.

The EIRS burner is a gas burner of the nozzle mix type that produces a high-brightness flat flame. The swirling flat frame prevents the flame from contacting the aluminum melt, allowing the melt surface to be gently maintained, which suppresses the generation of oxides. It has a large turndown ratio, achieving stable combustion across the entire range of combustion amounts. The radiant heat from the high-brightness flame improves fuel efficiency. By maintaining stable combustion at a low air ratio, it minimizes excessive oxygen, which can cause oxides. Preheated air is available (up to 300°C). Since it uses a direct ignition method, a pilot burner is not required, simplifying the piping system. 【Features】 - Stable combustion can be achieved - The flame is a high-brightness swirling flame along the furnace wall - The combustion system is simple - Preheated air can be utilized - Easy maintenance and inspection *For more details, please download the PDF or feel free to contact us.
