What are the maintenance methods of the mold in the forging factory?

Large forgings are generally used in the key parts of large machinery. Because of the harsh working environment and complex force, the quality of large forgings is very high in the production process. Large forging not only needs to meet the required parts shape and size, but also important is to break the cast structure, fine grain, uniform structure, forging shrinkage holes, pores and porosity and other defects, improve the internal quality of forging. The larger the size of the ingot, the more serious the defects in the ingot, and the more difficult it is to improve the defects in forging, thus increasing the difficulty of forging. In the forging process, upsetting and drawing are the basic and indispensable processes. For forgings with special shape, die forging is also more commonly used. Proper use and maintenance of the mold is an effective way to improve the life of the mold. The main contents are as follows:

What are the characteristics of forgings compared with castings

What are the characteristics of forgings compared with castings

The microstructure and mechanical properties of metal can be improved after forging. Due to metal deformation and recrystallization, the original coarse dendrites and columnar grains are transformed into equiaxed recrystallized grains with finer grains and uniform sizes. The original segregation, porosity, porosity and slag inclusion in the ingot are compacted and welded, and the structure becomes tighter, which improves the plastic and mechanical properties of the metal.

2021 China Forging Die and Lubrication Seminar has come to a successful conclusion

On December 24, 2021, China Forging Association successfully held "2021 China Forging Die and Lubrication Seminar" in Tai 'an, Shandong Province. The seminar is held every two years, with more than 100 participants. Due to the impact of the epidemic and the temporary cancellation of enterprise visits, only more than 50 representatives attended the seminar. The conference focused on the hot, key, difficult and developing trends in the field of precision forging die and lubrication.
