Description

Technical Field

[0002] Graphite resistive heaters for high-temperature heat treatment furnaces are a common heating equipment component used in industrial heat treatment processes. These heaters utilize graphite as the resistance material, utilizing the electrical resistance of graphite to generate heat when electricity is applied, thereby heating the interior of the heat treatment furnace. Heaters for high-temperature heat treatment furnaces primarily include resistance wire heaters, silicon-carbon rod heaters, silicon-molybdenum rod heaters, and graphite resistive heaters. Graphite resistive heaters are widely used because they can achieve higher heating temperatures and provide better heating uniformity.
