Abstract

INSTALACION DE DECAPADO TERMOQUIMICO DE PIEZAS DE ACERO INOXIDABLE. CONSTA DE UN BAÑO DE SOSA FUNDIDA Y UN BAÑO DE ACIDO. EL DECAPADO SE EFECTUA INTRODUCIENDO LAS PIEZAS EN EL BAÑO DE SOSA A CONTINUACION EN UN BAÑO SULFURICO Y POR ULTIMO EN UN BAÑO FLUONITRICO. A CONTINUACION DEL BAÑO SULFURICO EXISTE UN BAÑO DE ENJUAGUE. SE PREVE UN INTERCAMBIADOR DE CALOR ENTRE LOS CIRCUITOS DE TRATAMIENTO DE LAS PIEZAS POR EL BAÑO SULFURICO Y EL BAÑO FLUONITRICO, SIRVIENDO LAS CALORIAS RECUPERADAS EN EL PRIMERO PARA CALENTAR EL SEGUNDO.
