A strand casting installation in which a conicity of a die is set during a casting procedure by 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.

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, 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.

An injector cooling block for holding at least one injector for introducing a medium into a metallurgical vessel. The injector cooling block is arranged in or on a wall of the metallurgical vessel. The injector block has at least one plate in which a cooling channel or a cooling bore through which cooling medium can flow is arranged. The cooling channel or cooling bore separate a hot zone from a cold zone. At least one measuring element for measuring temperature and/or mechanical elongation is arranged in the hot zone. The measuring element has at least one optical waveguide which is integrated into the hot zone or fastened to the hot zone.

Injector cooling block for holding at least one injector

A method for measuring the temperature in a mold by a fiber-optic measurement method and a correspondingly designed mold. For this purpose, light waveguides, through which laser light is conducted, are arranged in grooves in the outside surface of the copper mold plate. The temperature at several measurement points along the measurement fiber is determined by a temperature detection system. In particular, the method makes it possible to achieve much greater local resolution of the temperature measurements than that achieved by thermocouples.

A process for predicting longitudinal cracks during continuous casting of steel slabs. The local strand temperature is measured by thermocouples distributed in the mold wall. In this process, the risk of the strand rupturing as a result of longitudinal cracking is assessed statistically taking into account the current temperature values measured by the thermocouples arranged in the mold and the temperature values determined when no cracks are present.

Process for predicting the emergence of longitudinal cracks during continuous casting

The invention relates to a mould for casting metal, having a plurality of temperature measuring devices () that are arranged in a wall () of the mould in order to detect the temperature distribution at that location. In order to make it easier to install the plurality of temperature measuring devices in the wall and in order to increase the reliability of the measurement results from said devices, it is proposed according to the invention to arrange the temperature measuring devices () such that they are positioned fixedly with respect to one another in a module (), such that the temperature measuring devices together with the module form a structural unit which can be preassembled before the mould is installed. The structural unit is then fastened in or to the wall of the mould as the mould is being assembled.
