1-9. (canceled)
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 Pest;
- and
- calculating a location Pmes of the crater end based on the measured bending.
2 more elements
A continuous caster to cast a metal product, the continuous caster comprising:
- 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;
- at least one bending measurer located on at least one of the upper segment frames and able to emit a bending measurement signal;
- a processor disposed to receive the bending measurement signal and to calculate a location Pmes of the crater end based on the measured bending signal, the crater end location being the location where the cast metal product becomes fully solidified.
