This develops a new way for manufacturing large flange because the capacity limitation of vertical lathe size will be unneccesary to be considered.

Particularly, cladding technology for fashioned flange is applied first time in China. It solves the key of manufacture, and develops the new way for manufacture of large-size flange in future.

To design the conjunction method of principle, casting iron ring flange, support way and exertion of bearing improvement, innovation that go on of design idea and so on.
