Electromagnetic induction steel tube expander

Intermediate frequency expanding machine's main advantage lies in its own technical content, medium frequency induction heating technology of PLC control and intelligent constant temperature system, hole enlargement technology, medium frequency induction heating technology, hydraulic technology in a pipe machine, tube expanding efficiency and enhance product quality, has been widely used in steel industry, construction industry, military field.Second, the working principle of intermediate frequency expanding machine, round steel perforated leather, in cold drawn. Small cold drawn seamless steel tube expanding machine production process: the circular tube billet - heat - punch to heading, annealing and pickling and oil (copper) and multichannel time cold drawing (cold rolled) to the tube billet - heat treatment - straightening, hydrostatic test (NDT) - > tag to put in storage.Each step division of labor is clear, the company's production of high quality three-way machine, medium frequency elbow machine, push the production process of the machine is also their own production process.
