Zusammenfassung:Process for tempering a pouring spout (5) arranged between a storage vessel (3) for a melt (2) of copper or copper alloy and a casting mold (6) comprises providing the spout wall with a heat resistant lining layer (15) having a specific electrical resistance of 10 to 10 OMEGA .m. The lining layer is inductively heated by an electrical heater (16) arranged outside of the lining layer. An Independent claim is also included for the pouring spout. Preferred Features: The inductive heating is controlled and/or regulated. The heater has a frequency of 100-15000, preferably 1000-8000 Hz.
