Abstract
UN PROCESO DE FABRICACION DE UNA PROTECCION ANTICORROSION EN PAREDES DE TOCHOS DE ARRABIO Y EN TUBOR RECALENTADORES EN GASES CALIENTES CON AZUFRE, UTILIZADOS EN DISPOSITIVOS DE CONDUCCION A TEMPERATURAS SUPERFICIALES DE MAS DE 400 (GRADOS) C, ASI COMO UN MATERIAL EN FORMA DE POLVO ADECUADO DEBEN POSIBILITAR QUE ESAS PAREDES DE TOCHOS DE ARRABIO Y ESOS TUBOS RECALENTADORES EN GASES CALIENTES CON AZUFRE PUEDAN SER BIEN UTILIZADOS Y DE FORMA DURADERA. PARA TAL FIN, SE APLICA (PARA LA FORMACION DE UNA CAPA PROTECTORA - PREFERENTEMENTE, DE UN ESPESOR DE 0,2 A 1,5 MM-) UN POLVO METALICO EXTRAIDO DE LA CORRIENTE DE FUSION DE UNA COMPOSICION DETERMINADA CON UNA SUPERFICIE DE MAS DE 200 CM (AL CUADRADO) /G CON UN SOPLETE METALIZADOR AUTOGENO CON UN VOLUMEN DE CIRCULACION DE GAS DE COMBUSTION DE UNOS 1000 A 3000 NL/H, O D 1500 A 2500 NL/H. LA COMPOSICION PREFERIDA PRA EL POLVO METALICO TIENE: CR 15% A 35%, MN 0.05% A 3%, MO 0,05% A 5%, C 0,1% A 3%, SI 0.1% A 3%, AL 2% A 15%, CON UN RESTO DE HIERRO.
