Method to determine the crater end location of a cast metal product

A method to determine a crater end location of a cast metal product during casting, the crater end location being the location at which the cast metal product becomes fully solidified, the method comprising the steps of:

• casting molten metal in a continuous casting machine including a plurality of upper and lower segment frames bearing rolls, the upper and lower segment frames being located respectively above and below the cast metal product;
• estimating a location Pest within the continuous casting machine where the metal product becomes fully solidified;
• at least measuring a bending of the nearest upper segment frame of the estimated location Pes, wherein the bending is measured at least on two ends of the nearest upper segment frame;
• and
• calculating a location Pmes of the crater end based on the measured bending.
