• a heating device comprising a nominal power density into the metal product of greater than or equal to 5·105 W/m2, wherein the heating device is a first heating device;
• a homogenizing device, wherein the homogenizing device is a first homogenizing device, and wherein the homogenizing device is configured to reduce a temperature difference between a surface temperature of the metal product and a core temperature of the metal product to less than or equal to 50° C.,
• a treatment device for treating the metal product;
• and
• a conveying device for conveying the metal product from the heating device toward the treatment device.
