Abstract: Cooled rollers for handling and conveying metallurgical and ferro-metallurgical products, moving inside a furnace, each of these rollers being formed by a water-cooled central shaft on which discs are mounted perpendicularly to the said central shaft in order to serve as a support for the ferro-metallurgical products, wherein the said central shaft are provided with thermal insulation shields for avoiding radiative heat transfer between the atmosphere in the furnace and the cooled shaft of the said roller.

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.
