A method for setting a conicity of a die of a strand casting installation during a casting procedure, including the steps of: measuring temperature values along a centric measuring path running in a casting direction along an adjustably disposed die wall; measuring temperature values along a peripheral measuring path running in a casting direction along the adjustably disposed die wall, wherein the peripheral measuring path runs between the centric measuring path and a lateral periphery of the die wall, and a spacing of the peripheral measuring path from the lateral periphery of the die wall is smaller than a spacing of the centric measuring path from the other lateral periphery of the die wall; determining a centric temperature distribution curve along the centric measuring path from the temperature values measured along the centric measuring path; determining a peripheral temperature distribution curve along the peripheral measuring path from the temperature values measured along the 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.
Opening claim text (preview).
We claim: 1. 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. 2. The method according to claim 1 , including: increasing the conicity of the die when the difference is a negative value which is smaller than a pre-defined negative minimum value, reducing the conicity of the die when the difference is a positive value which is larger than a pre-defined positive minimum value, and maintaining the conicity of the die when the difference is in an open interval having an upper limit that is the positive minimum value and a lower limit that is the negative minimum value. 3. The method according to claim 2 , including varying the conicity of the die more intensely the more the difference differs from zero.
