In the actual production, preparation corresponding process with structure characteristic of each casting. Large casting types mainly include elongated, round and high-Large. For example, elongated beam and bed can prevent the casting deformation.
Improving quality is the best way to save energy and material. There are many casting processes and effect factor. But the quality controlling is very difficult, especially for large casting. No matter the tooling, molding process or melting, they all have high requirements. Every detail needs to be done well. Good quality of the molten iron is the key to producing successfully.
