Solution Cases [case-031]Energy saving of Mesh Belt Type Continuous Furnace

  • Binder degreasing (debinding)
  • Firing
  • Electrode Drying
  • Other
  • Continuous Furnace

Efforts to reduce energy consumption of the mesh belt furnaces used for heat treatment of electronic components and other products.

Support Process Firing, Debinding, Electrode Drying, Other various heat treatment
Model Introduced Mesh Belt Type Continuous Furnace
(Standard Muffle Type, Hydrogen Type, Multi-Inlet/Exhaust Type, AllFit Mesh Belt Type Continuous Furnace with Superheated Steam)

Problem

Among the total energy consumed during heat treatment with an electric furnace, it is only a portion that is directly used for heating the workpieces. The remaining majority is lost as dissipated heat or consumed in processes such as transport by mesh belt. Reducing these energy losses not directly used for product heating is a key challenge.

Solution

    [Hardware improvements]

  1. 1. Improved thermal insulation performance
    • Replaced the thermal insulation with one that has higher thermal insulation performance.
    • Revised the structure of the penetration part inside the muffle to reduce the amount of heat dissipation.
  2. 2. Optimized the mesh belt used for products conveyance
    • Reduced the mesh belt weight according to usage conditions with maintaining its strength.
  3. [Software improvement]

    • Reduce power consumption by switching furnace temperature, mesh belt conveyor speed, etc. to low load state (standby operation mode) while the furnace is not in operation.

Results

Through these four measures, we have halved total energy loss* and reduced energy consumption.
