Problem Description - Part: Aluminum heat exchanger- Operation: Brazing of a pipe to a short tube previously brazed to the heat exchanger header in a furnace - Equipment: All equipment including 60 kW, 10-30 kHz power supply, part handling system and control system with IR pyrometers already existed- Problems: Insufficient brazed joint depth -> Inconsistent process resulting in leakage and other defects- Variables:-> Limited coil type modification-> Coil dimensions-> Coil positioning-> Magnetic controller dimensions
Problem Description and Specifications - The customer contacted Fluxtrol Inc. for the following reasons: - They were unable to produce good parts for a contract they had won. - The problem was the new part had a sharper fillet than other parts they had worked with before. Figure 1. & 2. - In order to get the required depth in the fillet, they had to severely overheat the area (X) just above it resulting in almost through hardening.
Learn through the following case story, "Wheel Hub Heat Treating", how machine downtime, extended set-up, and scrapped parts were reduced due to use of Fluxtrol "A" and a new induction coil design.
Learn through the following case story, "Design of Stress Relieving Coil and Process", how savings were accomplished due to induction coil and process optimization.

In this course magnetic flux control is a generic term for modification of induction coil magnetic flux by means of installation of magnetic templates (magnetic flux controllers). Magnetic flux control due to application of non-magnetic bodies (Faraday rings or flux robbers) is not considered here. Magnetic controllers may significantly change magnetic field pattern and coil parameters; their application must be considered as a part of the whole induction system design. Because Controllers play different roles (magnetic flux concentration, shielding, distribution) they are called also Concentrators, Cores or Shields depending on application. - In many cases controllers fulfill several functions simultaneously.
Computer simulation has become a practical tool for everyday use in the induction industry. This Computer Simulation course teaches the user to design optimal systems, improve equipment performance, dramatically reduce development time and costs, better understand the process dynamics, etc.
