In actual production, how to deal with the deformation and instability of automotive forgings at high temperatures? Please provide an actual production case and write an article.
The deformation and instability of automotive forgings at high temperature is a common issue that can affect product quality and service life. Here, we take the piston of a certain model produced by a certain auto parts factory as an example to illustrate the solution.
- Material selection Selecting high-quality forging materials is key to preventing deformation and instability of automotive forgings at high temperature. Generally, high-strength and wear-resistant materials, such as forging steel, should be chosen.
- Process control Controlling the temperature and time during forging is critical in preventing automotive forgings from deforming and becoming unstable at high temperature. In actual production, it is necessary to control the temperature and insulation time of the heating furnace, adjust the hammering force and frequency of the forging machine, etc., to ensure that the forging process takes place at the appropriate temperature and time and prevent uncontrolled heat treatment that may result in deformation.
- Heat treatment Heat treatment is also a common method to prevent instability and deformation of automotive forgings. The forging is placed in a heating furnace for heat treatment to ensure that it is evenly heated and achieves an ideal structure, with excellent high-temperature resistance.
- Technical operation On the production site, workers need to strictly follow technical requirements. Workers need to monitor the operation of processing equipment and its control system, promptly discover and handle any problems that may cause forging instability and deformation.
Through the above methods, we can effectively avoid the deformation and instability of automotive forgings at high temperature, ensuring product quality and service life.
Case analysis: The piston of a certain model produced by a certain auto parts factory is prone to uncontrolled deformation under high temperature. This issue was successfully resolved through material selection, process control, and heat treatment. The specific methods are as follows:
First, high-temperature-resistant forging steel materials were selected, and their physical properties and chemical composition were tested and evaluated. During the forging process, the temperature and time were strictly controlled, and the hammering force was adjusted to ensure that the forging temperature and time were within an appropriate range. After forging, the forging was heat-treated, and its structure and performance were inspected to ensure they met the requirements. Finally, on-site production, strengthened monitoring of the control system of equipment, timely addressing equipment operational issues.
Through these improvements and optimization measures, the factory successfully solved the problem of piston instability and deformation, and the quality of the produced pistons met the needs of customers.
