SGL series energy-saving bright annealing machine is designed for synchronous inline bright heat-treatment of the pipe. This efficient&energy-saving machine adopts the advanced induction heating power supply, the new type DSP＋IGBT power supply.It uses IGBT inverter,DSP precision control,air-cooling structure(water cooling for induction coil),reduce the loss of system.It has perfect self-protection and self -diagnostic function,saves 15% energy comparing with the similar  product.
Product Characteristics：
Energy-saving,reduce consumption of electricity.
Environmental,do not need pickling process.
Improve efficiency,reduce labor cost.
Comparing with off-line annealing, it occupied less space.
The surface of the steel pipe is smooth without squama.
The steel pipe is straight without distinction.
Finish the product directly without extra treatment or processing.
Application:
O.D. ∮6mm-114mm
Material：300 series austenite ，400 series ferritic，dual phase steel and titanium alloy.
Power Supply：60KW------600KW
Note:The power of the power supply is matched according to the pipe diameter, pipe thickness and speed.
