What are the advantages of forging heat quenching of Dalian forgings?
Dalian forging heat quenching can improve the properties of forgings.Forging heat quenching can significantly improve the strength and hardness on the premise of maintaining plasticity and toughness.
Four stages of tempering of forgings in Dalian
With the increase of tempering temperature, the quenching structure of Dalian forgings will change a series. According to the structure transformation, tempering is generally divided into four stages: martensite decomposition, residual austenite decomposition, carbide transformation, carbide aggregation and growth and ferrite recrystallization.
Problems needing attention in forging process
Forging is a very important step in steel manufacturing. A good steel worker must have a good forging skill. The forging process needs to be exposed to some high-temperature processes, so we should pay attention to some problems in forging and should not ignore these small details.
Rare causes and treatment of overheating of piston rod
Rare reasons for overheating of piston rod:
1. The appearance of the piston rod is too detailed.
2. Sundries are mixed in the gas and oil in the filling and evaluation.
What are the technological contents of piston rod
The process of piston rod is the main content to be introduced below. Why is this content introduced? Because the process is very important for the piston rod, it is necessary for us to master it well in order to grasp the key points and better understand it.
What is the process and content of piston rod?
How does the piston rod work
The contact surface of the piston rod is a special material with certain elastic and plastic deformation. Such structural characteristics can ensure the operation effect of the piston rod, provide appropriate working performance and ensure stable working principle. Now this kind of piston rod will be used in many industrial occasions. It is mainly to use these structures to improve the whole operation fluency.
