Abstract

LA PATENTE AFECTA A UN PROCESO DE ENDURECIDO DE UN CUERPOO CILINDRICO HUECO DE ACERO, EN ESPECIAL DE UN TUBO DE ACERO, EN EL MARCO DE UN TRATAMIENTO DE MEJORA, EN EL QUE SE ENFRIA EL CUERPO HUECO DE LA TEMPERATURA DE AUSTENITIZACION EN UNA BARRA DE REFRIGERANTE, EN ESPECIAL EN UN BAÑO DE AGUA,DE FORMA QUE SE DISPONGA EL CUERPO HUECO CON SU EJE LONGITUDINAL PARALELO AL NIVEL DE BAÑO DEL REFRIGERANTESD, SIENDO SUMERGIDA SOLO UNA PARTE DE LA SUPERFICIE. EL CUERPO HUECO SE GIRA ENTONCES ALREDEDOR DE SU EJE LONGITUDINAL. PARA CITAR UN PROCESO Y UNA INSTALACION PARA LA EJECUCION DEL MISMO, CON EL QUE SE INTENSIFICA Y HOMOGENIZA SENSIBLEMENTE EL ENFRIAMIENTO DE CUERPOS HUECOS POR INMERSION GIRATORIA, SE PROPONE QUE EL REFRIGERANTE INMEDIATAMENTE POR DEBAJO DEL CUERPO HUECO SE AGITE AL MENOS TEMPORALMENTE.THE PATENT AFFECTS A HARDENING PROCESS OF A STEEL HOLLOW CYLINDRICAL BODY, ESPECIALLY OF A STEEL PIPE, IN THE FRAMEWORK OF AN IMPROVEMENT TREATMENT, IN WHICH THE HOLLOW BODY OF THE AUSTENITIZATION BAR IS COOLED REFRIGERANT, ESPECIALLY IN A WATER BATH, SO THAT THE HOLLOW BODY IS DISPOSED WITH ITS PARALLEL LONGITUDINAL AXIS AT THE BATH LEVEL OF THE REFRIGERANTESD, BEING SUBMERGED ONLY A PART OF THE SURFACE. THE HOLLOW BODY IS THEN TURNED AROUND ITS LONGITUDINAL AXIS. TO QUOTE A PROCESS AND A FACILITY FOR THE IMPLEMENTATION OF THE SAME, WITH WHICH THE COOLING OF HOLLOW BODIES IS SENSITIVELY INTENSIFIED AND HOMOGENIZED BY GIATORY IMMERSION, IT IS PROPOSED THAT THE IMMEDIATELY SPLASH REFRIGERANT IS SEALED.
