Continuous Annealing Furnace / Normalizing Furnace

The front and rear vacuum purge chambers enable high-quality annealing using a small volume of nitrogen (N2) gas. The low-cost high-productivity normalizing furnace continuously performs heat treatment.
Continuous Annealing Furnace / Normalizing Furnace

Feature

  • The front and rear vacuum purge chambers are attached and processing can be carried out with only a small volume of N2 gas.
  • Thanks to enriching LPG addition to the N2 gas atmosphere and highly accurate atmosphere control technology, even high-carbon steel can be annealed without surface decarburization at low cost.
  • We have manufactured high-carbon chromium bearing steel spheroidizing annealing furnaces, softening annealing furnaces and furnaces compatible with normalizing.

Since the front and rear vacuum purge chambers are used, only small volume of N2 gas is required. Enriching LPG is added to the N2 gas atmosphere and the highly accurate atmosphere controlling technologies can anneal even high-carbon steel without surface decarburizing at low cost. "All gas heating" is used for heating with regenerative burners from heating to soaking, and single-end burners for slow cooling, so running costs can be reduced.

Examples of product High-carbon chromium bearing steel and low-carbon steel spheroidizing annealing, various metallic material softening annealing and normalizing, isothermal annealing, cycle annealing, stress relieving and various other annealing
