2020-06-05 1071

Iron is widely distributed in nature, but we found and used it later, because iron is very sparse on the earth, and oxidized slightly. At that time, we couldn't get a lot of pig iron due to the level of ironmaking technology. At that time, we always regarded iron as a more precious metal with mystery. With the continuous development of ironmaking technology, we found that all kinds of crafts made of iron are very beautiful, which can be used to decorate homes and also to make decorations.

Iron is also in the planning of metal. The technological process of iron wire crafts is the same as that of metal crafts. With the development of industry, some auxiliary processes have gradually ended mechanization. The key technologies that determine the artistic quality of products, such as point cutting, filling and inlaying, chiseling and bonding, are still finished by manual operation, so we have a sense of considering the overall situation without losing the general sense.
