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.
