Product Features (Vacuum Melting Furnace)
- 5L Capacity, High-Purity Alumina Crucible
This vacuum atmosphere frit furnace has a 5L capacity. The crucible is made of high-purity alumina (99.9%), which is high-temperature resistant, corrosion-resistant, and does not contaminate materials. It is suitable for melting high-purity glass frit, frit, and enamel glaze.
- Top-Loading, Bottom-Outlet, Air-Cooled Outlet
The crucible has a top-loading and bottom-discharging design with a 6mm discharge port diameter. It is equipped with an air-cooling system to allow the melt to flow out smoothly, facilitating the preparation and casting of glass molten blocks.
- Heated Feeding Bin, Preheating Feeding
The feeding bin is designed for 5L and has a heating function (up to 400℃) for preheating materials. The bottom of the bin is designed with a DN80 valve and water-cooled piping, enabling continuous operation of feeding-preheating-melting, improving production efficiency.
- Vacuum-Sealed Structure, Vacuum Degree -0.098MPa
The electric furnace body adopts a vacuum-sealed structure and is equipped with a two-stage direct-drive rotary vane vacuum pump, achieving a vacuum level of -0.098MPa. The furnace lining steel plate is 6-20mm thick, double-sided welded, and can withstand a positive pressure of 0.2MPa, meeting the process requirements of vacuum melting and atmosphere protection.
- Water-Cooled Components: Furnace Top
The furnace top is equipped with water cooling, effectively protecting the seals and electrical components, and extending the equipment’s service life.
