Abstract

An induction heating unit for the corners of an elongated workpiece of rectangular cross section. The unit has a core formed of iron laminations, and preferably has occasional copper laminations interspersed with the iron laminations. Each lamination has a pair of windows which define a central leg and webs between the window and workpiece. A winding of copper tubing extends around the leg within the windows. The webs form an unbroken wall protecting the winding from exposure to the workpiece.
