A horizontal tube furnace is a heat treatment device with horizontally positioned heating tubes. Electric heating elements transfer heat to the sample within the tube, enabling high-temperature sintering, calcination, pyrolysis, and atmospheric reactions. Compared to vertical tube furnaces, the horizontal design facilitates sample placement and removal, making it particularly suitable for experiments and production processes requiring a long heating zone and continuous material loading and unloading.
