Amorphous Core Annealing Furnace

Industrial furnace for the release of internal stress in amorphous ribbons

We are a company that specializes in manufacturing equipment for transformer core production, where annealing furnaces are among the auxiliary equipment employed for the core annealing. Our annealing furnace is specifically designed to remove the internal stress from the amorphous ribbon core and to meet the annealing requirements for stress relief in the magnetic field after the amorphous ribbon core is shaped. Nitrogen gas protection is required during the annealing process to prevent oxidation of the core surface. Our annealing furnace ensures excellent loss characteristics, achieving energy efficiency and environmental benefits for transformers using amorphous ribbon cores.

FAQs
An amorphous ribbon core annealing furnace is a specialized device designed for amorphous ribbon core production line. It is used to remove internal stress from the cores after shaping, resulting in excellent loss characteristics and stable performance.
An annealing furnace works by controlling temperature and annealing duration to heat-treat the amorphous ribbon cores after shaping. Nitrogen gas is introduced during the annealing process to prevent surface oxidation of the cores, ensuring effective annealing.
The amorphous ribbon core annealing furnace is suitable for factories producing electronic and electrical equipment such as amorphous ribbon core transformers and inductors. It can enhance equipment performance and efficiency.
Transformers using amorphous ribbons, primarily composed of iron (Fe), are employed in power line transformers and industrial transformers. Compared to conventional materials like silicon steel, amorphous ribbons have lower no-load losses (core losses), approximately 1/5th of silicon steel.
The annealing furnace in our amorphous ribbon core production line effectively removes stress, improving the core loss characteristics and efficiency. It also contributes to energy-saving and environmental benefits in amorphous transformers.
Our amorphous ribbon core production line is highly popular due to its advanced performance and cost-effectiveness, which is not only preferred by domestic manufacturers but also exported to countries such as India, United States, Vietnam, Argentina, Philippines, Bangladesh, and receives positive feedback from buyers.
Our amorphous ribbon core production line can create C-core and toroidal core for transformers.
Our core cutting lines primarily consist of cutting and stacking systems, main drive, and control components.
Amorphous Core Cutting Machine

Amorphous cores are becoming a popular choice by transformer manufacturers because that using the amorphous metal core allows to build smaller transformers and generate lower noise when compared to silicon steel core transformer.
