1200℃ 1400℃ 1700℃ Vacuum Tube Furnace

① The vacuum tube furnace adopts a modular integrated structure, integrating the heating chamber, temperature control system, and safety protection within a rigid frame.  This results in a compact structure with excellent mechanical stability, providing a solid foundation for high-temperature applications;
② Shell Material: Made of selected high-quality cold-rolled steel plate (Q235), precisely formed by CNC machining. The surface is treated with phosphating and anti-static powder coating, creating a robust shell. It is anti-static, corrosion-resistant, and scratch-resistant, ensuring lasting quality;
③ Furnace Chamber: The furnace chamber consists of two parts, upper and lower, for easy replacement. The material is a high-performance artificial synthetic inorganic non-metallic material, amorphous silicon aluminum oxide, formed by integrated mold high-pressure die-casting. The overall structure is dense, highly insulating, and high-temperature resistant, possessing excellent thermal stability and good insulation;
④ Control Area: The operation control is located at the bottom of the equipment, avoiding the risk of controller damage due to excessive temperature caused by upward heat transfer;
⑤ Heating System: High-quality silicon carbide rods, silicon molybdenum rods, or resistance wires are arranged around the inside of the furnace chamber.  Through precise calculation and arrangement, a fast and uniform heat field distribution is achieved, with extremely high energy conversion efficiency;
⑥ Insulation Layer: A multi-layer composite insulation design is adopted, consisting of alumina fiber board and ceramic fiber blanket to form a thermal insulation barrier, greatly reducing heat loss, improving energy efficiency, and ensuring that the shell temperature remains within a safe range;
⑦ Furnace Tube: Different temperatures correspond to different furnace tubes: 1200℃ uses high-temperature quartz tubes, and temperatures above 1400℃ use corundum tubes;
⑧ Flange: Made of SUS304 material, precisely manufactured by CNC lathe, with built-in double O-ring seals. A negative pressure vacuum gauge is standard, displaying the vacuum degree inside the tube in real time. Inert gas can also be introduced through the inlet and outlet ports at both ends to meet various heat treatment process requirements;
⑨ Independent Temperature Limiting: An independent mechanical over-temperature protector, separate from the main control system, serves as a secondary safety guarantee. When the main control fails, it automatically cuts off the power supply, preventing over-temperature accidents, ensuring safety and reliability (optional);
⑩ Electrical Control Box: The electrical system is concentrated in a sealed junction box with standardized wiring, and is equipped with overcurrent, leakage, and short-circuit protection modules to ensure the electrical safety of the equipment under various working conditions.
