The heat treatment process of motorcycle forgings usually includes the following steps: Heating: the forgings are placed in the furnace for heating so that they reach the required temperature. Under normal circumstances, the heating temperature of motorcycle forgings is higher, usually between 700 degrees Celsius and 1000 degrees Celsius. Soaking: the forgings are kept at the required temperature for a certain time, so that the internal organization reaches a uniform state of thermal balance. The length of holding time depends on the material and size of the forging. Cooling: The forgings that have been insulated are cooled rapidly to make corresponding changes in their internal organization. Cooling method according to different requirements can choose air cooling, water cooling or oil cooling. Solution Treatment: For some forgings with solid solution elements, solid solution treatment is required to achieve the desired performance. Solution treatment is generally carried out at high temperatures so that the solid solution elements are dissolved in the matrix. Quenching (Quenching) : The forging is cooled rapidly after solution treatment to form the desired structure. Quenching allows forgings to have higher strength and hardness. Tempering: Forgings after quenching are usually too brittle and need to be tempered to remove internal stress and improve toughness and impact resistance. The tempering temperature and time depends on the material and requirements of the forgings. It should be noted that the heat treatment process of motorcycle forgings varies according to the material, size and requirements of the specific forgings, and the above is only the conventional process steps under general circumstances. The specific process parameters and methods should be adjusted and determined according to the actual situation.
