Abstract: An installation for the thermal treatment of metallurgical products, such as, particularly, thin slabs, obtained from at least one continuous-casting line and to be subjected to a rolling operation, which comprises:an induction-heating furnace which is located at the exit of the continuous-casting line and the power of which is adjusted so as to increase the temperature of the slabs to a mean value determined by the rolling requirements, without correcting the local temperature heterogeneities of each slab and;an equalizing or homogenizing furnace or zone located at the exit of said heating furnace, in order to correct the thermal heterogeneities inherent in each slab.
