Abstract

La presente invencion se refiere a un procedimiento para determinar una fragmentacion y/o posicion de un producto de aplicacion presentado sustancialmente en fase solida en un horno de arco con un receptaculo de horno, creandose senales acusticas a traves de un arco electrico entre un electrodo y el producto de aplicacion, midiendose las senales acusticas conducidas a traves y/o reflejadas a traves del producto de aplicacion por medio de sensores acusticos, estando previsto por cada segmento del receptaculo de horno dividido en varios segmentos de al menos un sensor acustico, determinandose mediante la valoracion de las senales acusticas medidas la fragmentacion y/o posicion del producto de aplicacion en el horno de arco.The present invention relates to a method for determining a fragmentation and / or position of an application product presented substantially in solid phase in an arc furnace with an oven receptacle, creating acoustic signals through an electric arc between an electrode and the application product, measuring the acoustic signals conducted through and / or reflected through the application product by means of acoustic sensors, being provided for each segment of the oven receptacle divided into several segments of at least one acoustic sensor, determined by The evaluation of the acoustic signals measured the fragmentation and / or position of the product of application in the arc furnace.
