In the field of casting, the casting methods are many, such as gravity casting, high pressure casting and low pressure casting, but whatever, it is in the scope of casting, so for us, not only to understand these casting way, but also to understand, casting a whole so that can let oneself understanding deepening and extensive, which can grasp the overall, and implement to the subtleties, don't miss any points. So, below small make up to explain about the casting, the concrete content is as follows.
Casting, it is mainly used in the blank shape, because its economy is better, so it is widely used, especially in some more complex shape parts, such as in automobile engine cylinder block and cylinder head, as well as some cutting up difficult parts, such as gas turbine nickel-based alloy parts. So, it has a lot of applications.
Sometimes in the casting, heat treatment, its purpose, and is in order to improve the quality of the material, or you can say that, through heat treatment, can improve the strength and hardness of the casting as well as its ability to resist wear and so on. And heat treatment, it can be divided into two kinds, one kind is not change material structure of heat treatment, another is to change will happen. For the former, we mainly used to eliminate the internal stress of castings. The latter, it can be divided into softening annealing, normalizing treatment, hardening and hardening treatment such as these, the effect is different.
