Induction annealing equipment of steel pipe takes the induction heating coil as the main components for continuous welding pipe machine, it heats the seam which has just been welded and quenched, to above the critical temperature and anneals it (seam) to avoid the potential crack .The fine-crystal-particle structure produced by this process will guarantee a steel pipe tenacious that meet all standard requirements of the specification.
1) Single power and frequency: **0/**0KW,**3KHZ
2) Thyristor IF power supply: SCM control, double PI ring adjustment for voltage and current, tank circuit uses tuning all-film capacitor and energy-efficient insulating transformer to match load.
3) Online annealing inductor and mechanical adjustment system consist of plane inductor with magnetic material, mechanical adjustment system and capacitor cabinet.
4) Switch cabinet consists of isolation switch, complex triip, DW*7 automatic air switch and power grid isolation and step-up rectifier transformer.
5) Integrative console has IF power ON/OFF control, welding seam annealing temperature control and record files and so on function.
