Abstract

METODO PARA DETECTAR DEFECTOS SUPERFICIALES EN PIEZAS DE TRABAJO, PARTICULARMENTE EN TOCHOS.CONSISTE EN CALENTAR LA SUPERFICIE DE LAS PIEZAS DE TRABAJO POR MEDIO DE UNA CORRIENTE DE ALTA FRECUENCIA, MIENTRAS QUE LA PIEZA DE TRABAJO ES OBLIGADA A PASAR EN SU DIRECCION LONGITUDINAL A TRAVES DE UNA BOBINA DE INDUCCION DE ALTA FRECUENCIA, SIENDO INMEDIATAMENTE EXPLORADA, MIENTRAS LA PIEZA DE TRABAJO ESTA AUN PASANDO A TRAVES DE LA BOBINA POR MEDIO DE UN EQUIPO DE RAYOS INFRARROJOS PARA REGISTRAR LA DISTRIBUCION DE TEMPERATURAS A TRAVES DE LA PIEZA DE TRABAJO. EL COEFICIENTEDE EMISION PARA LAS PIEZAS DE TRABAJO DIFERENTES ES AUMENTADO, Y LAS VARIACIONES COMPENSADAS, HUMEDECIENDO LA SUPERFICIE DE TRABAJO CON UN LIQUIDO, POR EJEMPLO AGUA, CON ADICION DE COMPONENTES QUE REALIZAN UNA REDUCCION DE LA TENSION SUPERFICIAL Y DEL PUNTO DE CONGELACION.
