SGM 1400℃ Vacuum Atmosphere Furnace Introduction:

The SGM 1400℃ vacuum atmosphere lift furnace is equipped with silicon carbide rods as heating elements. It features a double-shell structure and Yudi's 30-stage temperature control system, with phase shift triggering and silicon-controlled rectifier control. The furnace chamber is lined with 1600-type alumina polycrystalline fiber material. The double shell is equipped with an air-cooling system for rapid heating and cooling. The furnace boasts balanced temperature distribution, low surface temperatures, fast heating and cooling rates, energy-saving features, and easy material handling without the need for crucible tongs to reach inside the furnace chamber.

SGM 1400℃ Vacuum Atmosphere Elevating Furnace Applications:

The SGM 1400℃ vacuum atmosphere lift furnace is suitable for high-temperature material retrieval and annealing, etc. It is a good product for universities, research institutions, and industrial enterprises to use in powder sintering, ceramic sintering, glass melting, high-temperature experiments, and quality inspections.

SGM1400℃ Vacuum Atmosphere Furnace Features:

1. The furnace chamber features a three-shell structure, with an inner lining inside the sealed layer. It is vacuum-tight, preventing any compression on the furnace chamber.

2. Heating Element

1) The hot end diameter D1 of silicon molybdenum rods is 7mm, which is thicker than the commonly used 6mm by most manufacturers. The heating end is robust, less prone to bending, and features a low surface load, resulting in a longer service life.

2) Utilizes hot bending technology for even resistance and long service life.

3) Lu cold end length is 210mm, 400X300300 furnaces for $260, most manufacturers use 180mm, cold end long furnace top temperature is low.

4) The surface of silicon molybdenum rods has a dense amorphous oxide film, which effectively protects the rods.

3. Equipped with air switches and residual current protectors:

When the circuit overloads or leaks, the switch will automatically disconnect.

4. Furnace chamber

1) High-purity aluminum oxide polycrystalline fiber solidification furnace with vacuum suction filtration molding.

2) Molded using Japanese technology.

3) The spacing and pitch of the resistance wire in the furnace chamber are all arranged according to the thermal engineering technology of Japanese design, and have been simulated for temperature distribution using thermal engineering software.

4) Utilize a 4-week heating process for a more balanced temperature field.

5) The furnace chamber does not shed powder, has good thermal insulation properties, high reflectivity, balanced temperature field, and strong resistance to thermal expansion and contraction.

5. Sealing System:

The SGM 1400℃ vacuum atmosphere lift furnace features a top cover and door (already welded elsewhere) sealed with silicone O-rings for easy installation and removal, repeatable removal, and excellent airtightness.

Atmospheric Furnace Point:

1. Can be braced on all four sides of the furnace chamber for more uniform temperature distribution.

2. Easy access to materials, especially when handling them under high temperatures. Users can retrieve materials from the tray once they have cooled down from the furnace, thus avoiding the radiant heat of the furnace and preventing burns.

3. The pallet features four supports around its edges, ensuring the materials are extremely stable on the pallet.

(Bonus Option) Explosion-proof System: The explosion-proof system is composed of components such as solenoid valves, microcomputers, pressure displays and transmitters, 24V power supply, and AC contactors. The pressure inside the furnace is converted into an electrical signal by the pressure display and transmitter and transmitted to the microcomputer. The microcomputer compares the signal with the set values and then sends signals to control the AC contactor, thereby controlling the opening and closing of the solenoid valve. When the pressure inside the furnace exceeds the allowable pressure set by us, the solenoid valve immediately opens to prevent explosion. An exhaust pipe is installed on the solenoid valve, allowing the user to connect a tube to expel the gas outdoors.

The explosion-proof system has many features:

1) Reusable: The solenoid valve opens when the pressure exceeds the set value and closes when the pressure falls below the set value. Unlike mechanical explosion-proof devices, it can be used repeatedly after being exploded once.

2) Adjustable setpoints: Users can adjust the opening pressure of the solenoid valve via a microcomputer to meet their needs.

3) Highly sensitive explosion-proof points: Due to the use of microcomputers and electrical signals, the explosion occurs immediately upon reaching the explosion-proof point.

4) Explosion-proof system safety: No fragments are ejected during initiation. (Glass fragments may be ejected if a mechanical system is used.)

5) Excellent explosion-proof system stability: Due to the use of microcomputers and solenoid valves, the system will definitely trigger at our set point, allowing users to test it. Unlike mechanical systems, which cannot be tested, there is much uncertainty about whether it will open at the explosion-proof point.
