Inclined Rotary Tube Furnace 1200℃ | Quartz Tube Atmosphere Furnace

Product Description

The inclined rotary tube furnace is designed for continuous powder calcination, reduction, coating, and material modification under controlled atmosphere or vacuum.

Equipped with a rotating quartz glass tube (Ø200mm), adjustable tilt angle (1–15°), and rotation speed (1–15 rpm), the furnace ensures uniform heating and effective powder flow. With PID programmable temperature control (30 segments), high vacuum sealing (-0.1 MPa), and robust dual-layer cooling structure, it provides high stability and flexibility for both research and industrial-scale production.

This model is widely used in ceramics, powder metallurgy, catalyst preparation, lithium-ion battery materials, and new material synthesis.
