# Steam Activation Tube Furnace

The CVSIC Steam Activation Tube Furnace is an advanced thermal processing system explicitly designed for sintering and activating powder and granular materials. It features dynamic sintering and integrated steam activation, ensuring materials are continuously and evenly heated throughout the process. This design delivers high-efficiency thermal transfer and consistent sintering quality.

The furnace chamber is constructed with high-purity alumina polycrystalline fibre insulation and uses molybdenum-containing resistance wires for stable heating up to 1100°C (recommended operating temperature 1000°C). The 310S stainless steel rotating tube (Ø80 mm at the narrow end, Ø300 mm at the wide end, with a heating zone of 400 mm) features four lifting plates to enhance material turnover. The tube rotates at 0–7 rpm and can tilt between 0 ° and 15° to facilitate effective dynamic sintering.

Integrated with a 6 kW steam generator (8 kg/h), this furnace supports water-vapor activation to enhance the physical and chemical characteristics of treated materials. Equipped with a 50-segment programmable controller, the temperature accuracy is ±1°C, with thermal uniformity within ±5°C. It is ideal for small-scale production and R&D in the battery, ceramic, and chemical materials industries.
