Bell Pit Type Spheroidizing Annealing Furnace

Loading Capacity

10-25 tons/batch

Application
  • Wire rods

  • Low and medium carbon steel

  • Alloy steel
  • Bearing steel
Heating Method

Electric or natural gas

Protective Atmosphere

Methanol and nitrogen

FEATURE
  • Oxide-Free Surface: After annealing, the material surface is free of oxide scale, slightly decarburized, with a high spheroidization rate and stable quality.

  • Advanced Lid Design: The furnace lid (with direct methanol injection port) is insulated with ceramic fiber cotton for enhanced heat retention, and its structure is lighter and stronger.

  • High-Efficiency Furnace Body: Premium ceramic fiber walls, multi-layer insulation, and seamless heat barrier ensure excellent thermal performance.
  • Durable Inner Chamber: Lightweight convection-optimized structure delivers longer lifespan and even temperature distribution.

  • Powerful Circulation Fan: High airflow and intensity for rapid heating, energy efficiency, and reduced processing time.
