Abstract

PROCESO PARA LA PRODUCCION DE UN ACERO ESTRUCTURAL IGNIFUGO, CARACTERIZADO POR LA COMBINACION DE UN ACERO DE POCO-C POCO-MN INCLUYENDO CANTIDADES DEFINIDAS DE TI Y NB CON UN TRATAMIENTO DE RODAMIENTO CONTROLADO Y ESPECIFICO. EL RESULTADO ES UN PRODUCTO PARA UTILIZARLO EN UN MEDIO EN ESTRUCTURAS PEQUEÑAS, LAS CUALES, A TRAVES DE LA EXPOLIACION DEL EFECTO SINERGETICO DE COMPOSICION Y TRATAMIENTO, ES SOMETIDO A UNA PEQUEÑA PERDIDA DE PROPIEDADES DE RESISTENCIA A TEMPERATURA ELEVADA EN LA EXPOSICION AL FUEGO, QUE ES EL CASO CON OTROS PRODUCTOS SIMILARES, REDUCIENDO ASI LA NECESIDAD DE RECUBRIMIENTOS PROTECTORES Y DE AQUI EN ADELANTE BAJAR LOS COSTES DE INSTALACION; LOS COSTES DE FABRICACION DE ACERO SE MANTIENEN BAJOS TAMBIEN POR QUE ES MINIMIZADO EL USO DE ELEMENTOS QUIMICOS, SE GARANTIZA TAMBIEN UNA BUENA SOLDABILIDAD.
