Continuing our series of industrial electric heaters we would like to focus on the essence of ceramic heaters and their role in industrial processes,

especially in the heat treatment of steel in electric hardening furnaces.

Ceramic heaters are advanced heating elements characterized by:

  • high thermal resistance - efficiency up to 1000°C, exceeding metal heaters.
  • excellent thermal insulation - minimizing heat loss, increasing energy efficiency.
  • long-term stability - resists corrosion and degradation for longer service life.
  • even heat distribution - uniform heating, crucial for process efficiency.
  • high mechanical strength - resistance to impacts and shocks in industrial environments.
  • low electromagnetic emission - minimal electromagnetic interference, important in precision processes.

Construction of Ceramic Industrial Heaters:

  • Heating Element: a core made of a material resistant to high temperatures, often silicon carbide or magnesium oxide.
  • Ceramic Housing: outer layer of ceramic, providing insulation and protection to the heating element.
  • Connectors and Insulators: protecting electrical connections and preventing heat conduction to the outside.
Construction of heaters

Application in steel hardening:

  1. Precise heating of steel: ensures uniform temperature, necessary to achieve optimal mechanical properties. Dedicated to processes such as hardening, firing, sintering, heating, tempering, annealing, heating for forging.
  2. Integration with temperature control systems: cooperation with, among others, MultiCon CMC-99 and SCT300 to ensure accurate monitoring and regulation of the process.

Application in electric hardening furnaces:

  1. Efficient heat generation: ensuring high energy efficiency.
  2. Long-lasting operation: high temperature resistance and minimal wear.
