Seam Annealer

PSTEK’s seam annealer uses a differentiated coil that we designed based on electromagnetic field computer analysis for higher durability and efficiency compared to foreign facilities, and automatically adjusts heating power according to speed for higher quality of the seam-line annealer.

Our company suggests and provides the optimum power supply, heating coil and apparatus configuration based on customer needs in terms of pipe specifications, production speed and installation space, a feat we can accomplish thanks to our history in various pipe and tube heat treating applications, large-capacity power supply, and on-site engineering.

Features & Benefits

  • The magnetic density against the same current is increased based on electromagnetic field computer analysis to optimize the delivery of heat distribution and maximize effective efficiency
  • The coupling of the coil apparatus is increased to enable a heating reduction and improve cooling, and ultimately to ensure higher durability
  • The output power is automatically regulated in accordance with changes in steel grades and temperature
  • Correct output regulation for a higher yield rate and a lower defect rate
  • A wide matching range to smoothly respond to changes in the electrical resistance of different heating temperature sections
  • Seam tracking function: If the heat treatment location of materials is missed, the location of the heating coil is automatically adjusted by checking the core part of materials
  • The distance between materials and coil is maintained by adjusting the heights of the input and output parts of heating coil to ensure the annealing quality (based on the z-axis)
  • Copperplate multilayer transformer applied: The efficiency has been enhanced by considerably improving proximity effect and skin effect compared to other methods
     ※ Patent pending(10-2005-0041829, 10-2005-48935)
  • IGBT, the newest semiconductor device, is used to lower the heating degree and considerably increase the switching width
