Heat treatment of cast iron platform is one of the important processes in mechanical manufacturing. Compared with other processing methods, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemistry of the surface of the workpiece. Ingredients that impart or improve the performance of the workpiece. It is characterized by improved internal quality of the workpiece, which is generally not visible to the naked eye.

Annealing: A heat treatment process in which a metal material is heated to a suitable temperature for a certain period of time and then slowly cooled.
Common annealing processes are: recrystallization annealing, stress relief annealing, spheroidizing annealing, complete annealing, and the like.
The purpose of annealing: mainly to reduce the hardness of metal materials, improve plasticity, to facilitate cutting or pressure processing, reduce residual stress, improve the homogenization of tissue and composition, or prepare the tissue for the subsequent heat treatment. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the rational selection of materials and various forming processes, heat treatment processes are often essential.
Steel is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium, and the like can also be modified by heat treatment to obtain different mechanical properties, physical properties, and chemical properties.
