What is the purpose of induction heating furnace annealing? Which parts are commonly used?
In induction furnace annealing, the workpiece is cooled in the air after it is heated to the annealing temperature. Therefore, it is actually induction normalizing, but it is customarily called annealing.
Induction heating furnace annealing is widely used in steel pipe welds using induction heating furnaces, recrystallization annealing of workpieces after cold shovel (such as high-pressure tubing connections), and some workpieces that require partial annealing after carburization (such as motorcycle connecting rods, flowers) The threaded part of the key shaft, etc.). The steel pipe weld seam adopts an Induction heating furnace to normalize the coarse and uneven grains of the weld seam to obtain fine grains; the local annealing of the cold forging workpiece restores the elongated grains after the cold arrogance to fine and uniform grains, so as to prevent the workpiece from being damaged. Some parts are damaged due to reduced mechanical properties during use; parts of carburized parts such as threaded parts are annealed mainly to reduce the hardness of this part.
