Abstract
PROCEDIMIENTO DE AFINADO DE METAL Y CRISOL PARA SU REALIZACION. EL PROCEDIMIENTO CONSISTE EN INYECTAR POR EL PIE DEL CRISOL UN GAS DE AGITACION EN LAS PROXIMIDADES DE LA PARED LATERAL, EN LAS PROXIMIDADES DE LA VERTICAL DEL PIE DE BASCULADO DEL CRISOL; DURANTE EL AFINADO SE DETERMINAN LOS PARAMETROS INDICATIVOS DE LA TENDENCIA A LA NITRURACION DEL BAÑO. EL CRISOL PRESENTA INCORPORADOS A SU REVERTIMIENTO INYECCIONES PARA LA INSUFLACION DEL GAS DE AGITACION, LOCALIZADOS EN EL FONDO DEL CRISOL EL MENOS, SEGUN UNA CORONA PERIFERICA SITUADA EN LAS PROXIMIDADES INMEDIATAS A LA PARED REFRACTARIA LATERAL DEL CRISOL.
