Abstract
The invention relates to a method for cooling a tool in a heat treatment furnace, wherein: the tool is supplied during normal cooling operation with coolant from a coolant reservoir through a supply inlet (), which coolant is returned into the coolant reservoir from the tool via a return flow (); the supply inlet () is coupled by means of an electric actuator () alternatively to the coolant reservoir or to the public water supply and the return flow () is coupled by means of a further electric actuator () alternatively to the coolant reservoir or to the public waste water system (); the actuators (′) are supplied with a feed current during normal cooling operation and held in a first position in which coolant is supplied to the tool through the supply inlet () from the coolant reservoir and the coolant is fed back through the return flow () into the coolant reservoir; and, upon interruption in the power supply, the actuators (′) are forced into an emergency position in which cold water is supplied to the tool through the supply inlet () from the public water supply and the water is discharged through the return flow () into the public waste water system ().
