Abstract

Procedimiento y dispositivo para la medicion de la excentricidad de una tubería fundida (acabada al calor) sin costuras. 1. La presente invencion se refiere a un procedimiento para la medicion de la excentricidad de una tubería de acero acabada al calor sin costuras durante el proceso de fabricacion, en el cual el tubo es fabricado como tubo hueco en bloque compuesto de un bloque masivo o a partir de un tubo hueco en bloque ya dispuesto, donde el bloque masivo o tubo hueco en bloque es calentado por sobre la temperatura Curie y es laminado bajo aplicacion de una herramienta interior y la herramienta interior presenta una temperatura por debajo de la temperatura Curie durante el proceso de laminado, y el bloque, o bien tubo hueco en bloque es transportado a través del laminador, o bien sobre la herramienta interior axial fija. Para la simplificacion del procedimiento se prevé que, inmediatamente después de la salida del laminador, sean inducidos campos magnéticos sobre el impulso de la corriente de Foucault en el tubo así como en la herramienta interior, donde la diferente permeabilidad magnética del tubo calentado y de la herramienta interior, dependiente de la temperatura, capta ocurrencias de senales de corriente de Foucault. De esta forma, los campos magnéticos son inducidos y evaluados y, así, la excentricidad de la herramienta interior puede ser determinada en relacion al tubo en forma continua.Procedure and device for measuring the eccentricity of a molten pipe (heat finished) without seams. 1. The present invention relates to a method for measuring the eccentricity of a heat-finished steel pipe without seams during the manufacturing process, in which the tube is manufactured as a hollow block tube composed of a massive block or from a hollow block tube already arranged, where the massive block or hollow tube block is heated above the Curie temperature and is laminated under application of an inner tool and the inner tool has a temperature below the Curie temperature during the rolling process, and the block, or hollow block tube is transported through the laminator, or on the fixed axial inner tool. For the simplification of the procedure, it is envisaged that, immediately after the output of the mill, magnetic fields are induced on the impulse of the eddy current in the tube as well as in the inner tool, where the different magnetic permeability of the heated tube and the Inner tool, dependent on temperature, captures occurrences of current signals from Foucault. In this way, the magnetic fields are induced and evaluated and, thus, the eccentricity of the inner tool can be determined in relation to the tube continuously.
