1. Heating elements are distributed around the furnace chamber, fully surrounding the furnace tubes at 360 degrees, enhancing temperature uniformity inside the furnace;

2. High-purity Al2O3 fiber refractory insulation material, with superior insulation effect, effectively reducing the power consumption of the equipment; 3. The furnace body adopts a double-layer air-cooling structure, which helps to reduce the surface temperature of the shell; 4. Intelligent PID fuzzy temperature control is used, with a 7-inch touch screen for centralized operation, capable of intuitively displaying "time-temperature" curves; 5. An integrated water-cooled flange is adopted to prevent the flange from overheating and damaging the sealing ring, fully ensuring the equipment's airtightness; 6. Self-developed electromagnetic hoist release technology is used to achieve rapid quenching treatment of materials;
