Definitions
- the invention relates to a method for the treatment of sheets, which are rolled in a roll stand to the final dimensions are then cooled online, directed and heat treated for homogenization and microstructure.
- the heat treatment devices e.g., heating and cooling units
- the heat treatment devices are separate from the direct production flow from the rolling heat in separate locations beyond the cooling beds.
- the object of the invention is to improve the possibilities of heat treatment in the online process.
- This object is achieved according to the invention in a process for the treatment of sheets which are rolled in a roll stand to the final dimensions then cooled online, directed and heat treated for homogenization and microstructure, characterized in that the heat treatment online but decoupled from the previous cooling and straightening " takes place, taking into account the speed of emerging from the upstream last processing station sheet, the time of the beginning of the heat treatment is selected so that the sheet has completely left this last processing station before the sheet is subjected to the heat treatment.
- the invention also assumes to arrange an inductive heating directly in the production flow behind the Rieht- and Abkühlaggregaten and to heat the coming out of the mill, cooled and directed or directed and cooled finished sheet. By means of this heat treatment, the material properties can be influenced in a targeted manner over the thickness and the width, and temporally detached from the previous processing.
- the heat supply for the heat treatment is carried out inductively.
- the heat can be advantageously carried out by insertable into the production line induction coils, on the top and / or bottom of the sheet.
- the induction coils serving the heat supply should be independently switchable.
- Fig. 2 shows a detail of the inductive heating device and Fig. 3 shows the course of the heating over the sheet metal cross section at a plate thickness of 25 mm and a heating of 34O 0 C to 650 0 C.
- 1 designates the rolling mill stand and 4 designates the inductive heating device.
- the inductive heating device can - as Figure 2 shows - consist of several induction coils 5 and 6, which are arranged below and above the roller table 7. 8, the finished sheet is designated in this schematic representation.
- Figure 3 clearly shows the different heating of the core or the surface of a sheet, ie, starting from the inlet temperature in the heat treatment device of 350 0 C, the complete homogenization of the temperature to 650 ° C is reached only after about 130 sec. Such a residence or treatment time can only be achieved if the heat treatment is not temporally restricted in terms of speed by the previously proceeding process steps, that is, the treatment stations arranged upstream and used.
