Bell Furnaces provide controlled annealing of steel strips and wire coils to relieve internal stresses, restore ductility and achieve the required mechanical and metallurgical properties. Operation under Hydrogen, Cracked Ammonia or Nitrogen protective atmospheres minimizes oxidation and decarburization while ensuring a clean, uniform surface.
SWASTIK Bell Furnaces feature high-efficiency extended-shaft motor assemblies for enhanced convection, close temperature uniformity, consistent material properties and improved recrystallization. Advanced pulse-firing, PLC/SCADA-based controls and combustion management systems ensure precise process control and energy efficiency. Polykath dehumidification, coil cooling and storage systems are also available for efficient post-annealing handling and conditioning.
Our latest 100% H₂-HC-LEC Version 3.0 Bell Furnace represents an advanced evolution of our earlier version of Bell Annealing Furnace. High Convection (HC) and Low Energy Consumption (LEC) technology enhance heat transfer, temperature uniformity Substantial reduction in fuel consumption and overall process efficiency, making it ideally suited for the annealing of steel strip coils.
