Abstract: A hot dip batch coating pot for containing a coating material in a liquid state. The pot comprises a container portion having a horizontal bottom and vertical side walls, with the bottom and said side walls defining an interior volume for containing said coating material. At least one coreless induction furnace is mounted on a side wall of the container portion. The coreless induction furnace defines an interior volume in communication with the interior volume of the container portion for inductively heating the coating material. The coreless induction furnace is disposed at an angle to the vertical.

Abstract: In the operation of a hot metallizing furnace for lengths of metal, in particular metal strip, in which the length of metal to be coated is passed from above through the upper zone of a smelt of a coating material located in a smelt container, the smelt container can be heated by means of an induction coil made up of partial coils arranged axially on top of one another. During hot metallizing the upper partial coil(s) is/are connected to a medium frequency source of electricity in a single-phase manner. For the removal of the deposits which accumulate in the lower area of the smelt vessel, the lower partial coil(s) is/are connected to a three-phase current mains frequency source of electricity. The agitated deposits are then removed from the smelt using a collecting vessel.
