What is induction annealing?
Induction annealing is a heat treatment process that uses induction heating to anneal metals. It slowly heats the metal to a certain temperature (the recrystallization temperature) for a sufficient time, and then cools at a suitable rate. Induction annealing can reduce the hardness and internal stress of the workpiece, increase the ductility of the workpiece, and improve the reprocessing performance of the workpiece.
Induction heating can precisely adjust the heating power to easily control the annealing temperature. Induction annealing is a repeatable process for heating the workpiece, so it is easier to control the heating result of the workpiece. Induction annealing equipment is easily integrated into the production line, enabling automation and improving production efficiency.
Induction annealing is widely used in the tube and wire processing industry. It is commonly used in the annealing of steel wires, steel pipes, blades, saw blades, copper pipes, aluminum rods and aluminum pipes.
