[0002] The high-temperature furnace body is an important high-temperature corrosion-resistant spray pyrolysis furnace body for plating tin oxide thin films on the outer wall of tubes. Its working principle is to control through a solid-state relay, so that its heating wire generates heat energy in the on-off state, and then forms far-infrared heat radiation through a silicon carbide plate. It has the advantages of high heating temperature, strong corrosion resistance, and high heat energy, and has obvious advantages in processing material devices with relatively high infrared transmittance.
