Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION DE UN TUBO FABRICADO EN CALIENTE SIN COSTURA A PARTIR DE ACERO CON DEFORMABILIDAD REDUCIDA, EN PARTICULAR ACERO APOYADO EN RODILLOS, PROPONIENDOSE DE ACUERDO CON LA INVENCION QUE UN ACERO LIQUIDO PREVIAMENTE CALENTADO Y DESGASIFICADO, ASI COMO DESOXIDADO DE LA COMPOSICION QUIMICA REQUERIDA, SEA FUNDIDO CONTINUAMENTE CON CUALQUIER SECCION TRANSVERSAL, DESPUES DE LA SEPARACION DE PLETINA, SIENDO DIVIDIDO PARA LA FUNDACION EN LONGITUDES ADECUADAS Y PERFILADAS. LA INVENCION PROPONE QUE LAS LONGITUDES DE CORTE A SER CALENTADAS HASTA LA TEMPERATURA DE PERFILADO SIN CUALQUIER PERFIL PREVIO, POR EJEMPLO COMO FUNDICION, Y SIN NINGUN TRATAMIENTO TERMICO (RECOCIDO DE DIFUSION), SEA GUIADO A UNA PLANTA DE PRODUCCION DE TUBOS.
