What is induction annealing


This process heats metals that have undergone extensive treatment. Induction annealing reduces hardness, improves ductility and relieves internal stress. Whole body annealing is the process of annealing the entire workpiece. With weld annealing (more accurately called weld normalization), only the heat-affected zone created by the welding process is treated.
what is the benefit?
Induction annealing and normalizing provide fast, reliable and localized heat, precise temperature control, and easy in-line integration. Each workpiece processed by induction meets precise specifications, and the control system continuously monitors and records the entire process.
where is it used?
Induction annealing and normalizing are widely used in the tube industry. It also anneals wire, steel strip, blades and copper tubing. In fact, induction is ideal for virtually any annealing task.
What equipment are there?
Each DAWEI induction annealing system can meet specific requirements. The core of each system is
DAWEI induction heating generators feature automatic load matching and constant power factor at all power levels. Most of the systems we deliver also feature custom handling and control solutions.


Hangzhou Yinda Electric Furnace Co., Ltd. is located in the scenic Qianjiang Economic Development Zone, Hangzhou City, with convenient transportation. Consisting of experts and professors of Zhejiang University who have been engaged in the R&D in the medium frequency, high frequency, super audio frequency, and another field for many years, our company is a manufacturing and service type enterprise which specializes in the design and production of all kinds of complete induction melting and heating equipment. Our company widely cooperates with the scientific research institutions both home and abroad and is devoted to researching and producing the complete equipment in induction heating, forging heating, heating treatment, quenching, soldering and brazing and another hot working field on the premise of taking the induction furnace (10kg-70T) as the leading product. Yinda Furnace developed the domestic advanced series type dual power source variable-frequency power supply (known as one-to-two) after introducing, digesting, and absorbing the foreign advanced technology. The power supply is energy-saving with less harmonic content and high efficiency and has been widely applied in the foundry industry.
