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.
Claims4
A system for thermally treating thin metallic slabs prior to rolling, comprising:
- means for continuously casting a thin metallic member;
- means for shearing the member to form slabs of predetermined length;
- means located downstream of the shearing means for inductively heating each sheared slab during a first period of time, in a first zone, to non-uniformly raise the temperature of the slab to a mean first preselected temperature;
- means for further heating each slab for a second period of time, in a second zone downstream of the first zone, to uniformly raise the temperature of each slab to a second preselected temperature;
- and
- roller means for rolling the heated slab therebetween to achieve a preselected thickness.
