Top quality heat treatment furnace heating element

                 Radiant Tube

Brief

For most of heat treatment process, atmosphere passed into furnace will corrode electrical heating element. To ensure the normal operation under special working environment, we need to protect the resistance wire or resistance tape effectively. Combining resistance wire or resistance tape and high temperature insulation pottery bracket into heating core, the heating core will electrify and heat inside high temperature resistant and corrosion resistant protective tube and conduct heat by protective tube to furnace space and workpiece.

User benefits include superior resistance to, for example, carburization, thermal shock, sagging and distortion. This is due to the materials' excellent mechanical properties and their capability of forming a dense and adhesive oxide film that protects against corrosion and atmospheric attack.
