What are the influencing factors of iron castings?

Do you know the influencing factors of iron castings? Let me tell you something. The influencing factors of cast iron are as follows: the first is the design process of iron castings. In the design, in addition to determining the geometric shape and size of iron castings according to working conditions and metal material properties, the rationality of the design must be considered from the point of view of casting alloy and casting process characteristics. that is, obvious size effect and solidification, shrinkage, stress and other problems, in order to avoid or reduce the composition segregation, deformation, cracking and other defects of iron castings.

How does the foundry prevent the shrinkage of aluminum castings in production?

The basic principle to prevent shrinkage and porosity of castings is to establish a correct casting process according to the characteristics of shrinkage and solidification of the alloy, so as to establish good feeding conditions in the process of solidification, and convert shrinkage into shrinkage as much as possible. and make the shrinkage appear at the last solidification of the casting.

Why can't steel castings be welded together?

Steel castings are the parts formed by cooling and solidification after pouring steel into a specific mold after melting. Steel castings are divided into ordinary carbon steel, low alloy steel, high alloy steel and so on. There are many problems in the welding process of large steel castings.
