Description

Technical Field

[0001] This utility model relates to the field of steel casting annealing technology, specifically to a gear casting annealing device. Background Technology

[0002] Annealing is a heat treatment process that alters material properties through heating and slow cooling. It is widely used in metals, glass, semiconductors, and other fields. Annealing of gear castings is a heat treatment process that improves material properties through heating and slow cooling. Uneven cooling during casting can easily generate residual stress; annealing can prevent deformation and cracking during subsequent machining or use. High-temperature annealing recrystallizes the coarse casting structure, improving the gear's mechanical properties (such as toughness and fatigue strength). It also reduces hardness, facilitating cutting and grinding, extending tool life, and preparing the gear for subsequent heat treatment.
