Method for setting a conicity of a die of a strand casting installation, and device for a strand casting installation

A method for setting a conicity of a die of a strand casting installation, during a casting procedure, comprising the steps of:

• measuring temperature values along at least one centric measuring path running in a casting direction along an adjustably disposed die wall;
• measuring temperature values along at least one peripheral measuring path running in a casting direction along the adjustably disposed die wall, wherein the at least one peripheral measuring path runs between the at least one centric measuring path and a lateral periphery of the die wall, wherein a spacing of the at least one peripheral measuring path from the lateral periphery of the die wall is smaller than a spacing of the at least one centric measuring path from an other lateral periphery of the die wall;
• determining a centric temperature distribution curve along the at least one centric measuring path from the temperature values measured along the at least one centric measuring path;
• determining a peripheral temperature distribution curve along the at least one peripheral measuring path from the temperature values measured along the at least one peripheral measuring path;
• determining a first area under the centric temperature distribution curve, and a second area under the peripheral temperature distribution curve;
• determining a difference between the second area and the first area;
• and
• setting the conicity of the die taking into account the difference.
