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

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies.
