Product Features (Vacuum Atmosphere Tube Furnace)

1. Rotatable and Tilting, Dynamic Heat Treatment

This vacuum atmosphere tube furnace features an adjustable tube rotation speed of 1-10 r/min and an adjustable furnace body tilt angle of 1-10 degrees. The rotation function ensures that the powder material continuously tumbles within the furnace tube, resulting in uniform heating; the tilting function facilitates continuous material feeding and discharging, making it suitable for dynamic heat treatment processes of powder materials.

2. Large Tube Design, High Material Handling Capacity

The furnace tube is made of quartz glass, with a total length of 1400 mm, a diameter of 200 mm, a 600 mm wide end, and a 200 mm conical discharge end.

3. Dual-Use Vacuum Atmosphere Furnace, Compatible with Multiple Atmospheres

Vacuum level -0.1 MPa, equipped with a mechanical vacuum pump. One inlet and one outlet, each equipped with a float flow meter (0-30 L). It can accommodate various protective or reactive gases to meet the requirements of vacuum sintering, atmosphere protection, reduction treatment, and other processes.

4. 304 Stainless Steel Flange Seal with Silicone Sealing Ring

The furnace tube seal uses a 304 stainless steel flange with a silicone sealing ring, ensuring reliable sealing performance. The flange structure is rationally designed for easy and quick installation, removal, and connection to the vacuum system.
