1700°C Four-Zone Tubular Furnace
Model: KTF17-D
Application: Batch heat treatment testing for a single sample at various temperatures
Specification: 800mm (200+200+200+200)
Features: Multi-temperature zones
Some heat treatment experiments may require an oven with one or more temperature gradients or a longer恒温 zone, such as for CVD coating tests. This triple-zone tube furnace allows for independent parameter settings for each zone, enabling different temperature values in various zones. By setting all three zones to the same temperature point, it can be used as an extended single-zone oven, commonly employed by LED phosphor manufacturers for production purposes.
A 1500mm long furnace tube with three temperature zones. Due to the inherent properties of the alumina tube material, it becomes brittle under long-term high-temperature production operations. Therefore, ensuring the extended service life of the alumina tube becomes crucial. To address this, we start with the production process of the alumina tube, selecting qualified raw materials and combining scientific and reasonable structural design, thus freeing users from the hassle of broken tubes.
