Abstract

The heat treatment of a track element which is heated over its entire length and then cooled in a coolant bath in such a way that, if necessary, the element is dipped - with its head portion leading - partially and with interruptions into the bath. According to a predetermined time sequence, the element is alternatingly dipped completely and partially into the coolant bath.
