Precision casting of nodular cast iron casting technology

H2. Precision casting technology can be summarized in developed countries to protect the environment, improve casting quality and reliability, reduce production cost and shorten delivery time.

H3. Ductile iron casting technology as an important part of casting technology, research on ductile cast iron casting should be on the "highway" as soon as possible. Looking forward to its development trend, our ductile iron casting technology, especially the thick wall parts, should be developed rapidly in the future.

H4. 1.Vigorously develop new spherification and gestation technology. The driving force of high strength and high ductile ductile iron production is the continuous improvement and improvement of spheroidization and gestalt technology. The development of gestation technology often hopes to develop new inoculants. However, in recent years, the improvement of breeding methods, especially in late pregnancy, has been taken seriously. Therefore, at the same time, the research on the pregnant technology will be changed to develop new incubation methods.

H5. 2.The research on new materials and new process of ductile iron should be the main objective of automobile industry, aerospace and nuclear energy industry, which is characterized by strength, lightness, precision and efficiency.

H6. 3.Ductile cast iron casting process is a complex irreversible process. In actual production, there are many uncontrollable factors or immature processes that lead to the castings being scrapped or unable to reach the desired technological targets, To carry out basic theoretical research on major technical equipment and precision casting technology, Develop numerical simulation, physical simulation and expert system, to make ductile cast iron foundry technology from "experience" to "quantitative".

H7. 4.Development of green intensive casting, to increase the precision casting process to environmental pollution control, to strengthen the regeneration and reuse of precision casting materials.

H8. 5.Realize online and intelligent. Ability to detect and control precision casting process or equipment online, ability to timely and accurately reflect the status of the site, to control the production equipment in real time so that the precision casting process or equipment is in the best condition.
