Treatment of hot rolling stock made of metal

A treatment process for hot rolling stock made of metal, the process comprising:

• rolling the rolling stock in at least one roll stand;
• cooling the rolling stock in a cooling section arranged downstream in a direction of the rolling of the rolling stock of the at least one roll stand;
• providing a sound generator arrangement;
• providing a control device;
• operating the control device to determine at least one control variable (C) based on actual properties (P) of the rolling stock before cooling in the cooling section and based on set point properties (P*) that the rolling stock is to have after cooling in the cooling section;
• feeding the sound generator arrangement the at least one control variable (C);
• generating sound by the sound generator arrangement and coupling the generated sound into the rolling stock upstream of the cooling section for forming a standing sound wave at least in a region of the rolling stock that is located in a vicinity of a coupling device;
• and
• operating the sound generator arrangement to set a characteristic quantity of the sound coupled into the rolling stock based on the control variable (C).
