Abstract

Los vástagos tapones (22) para la colada continua de meta en fusion poseen un cuerpo (22-3) y una punta (22-1) en un extremo inferior del cuerpo. La punta del vástago tapon define una superficie exterior troncoconica (22-1S) que termina en una nariz concava (22-1b). La nariz concava preferentemente es una superficie curvilínea (por ejemplo, un segmento esférico), no obstante lo cual es posible emplear en forma alternativa superficies no curvilíneas (por ejemplo, prismáticas, piramidales, triangulares, y cuadrangulares). La superficie exterior troncoconica (22-1S) de a punta del vástago tapo preferentemente forma un ángulo theta con respecto a un plano horizontal que es suficientemente amplio como para incrementar la velocidad del metal en fusion que fluye en orden a reducir el espesor de la capa límite de éste adyacente a las superficies de la boquilla y la punta del vástago tapon para minimizar la deposicion de inclusiones allí. Preferiblemente, el ángulo theta es superior a 70°.The plug stems (22) for continuous casting of the melting goal have a body (22-3) and a tip (22-1) at a lower end of the body. The tip of the plug stem defines a conical outer surface (22-1S) that ends in a concave nose (22-1b). The concave nose is preferably a curvilinear surface (for example, a spherical segment), however, it is possible to alternatively use non-curvilinear surfaces (eg, prismatic, pyramidal, triangular, and quadrangular). The outer truncated conical surface (22-1S) of the tip of the stopper rod preferably forms a theta angle with respect to a horizontal plane that is wide enough to increase the velocity of the melting metal flowing in order to reduce the thickness of the layer boundary of this adjacent to the surfaces of the nozzle and the tip of the plug stem to minimize the deposition of inclusions there. Preferably, the angle theta is greater than 70 °.
