Abstract
Un tapon para regular el flujo de un metal fundido desde un grupo de colada, por ejemplo, de acero o de hierro fundido desde un distribuidor o de unacuchara de colada, y más especialmente, un tapon en una pieza que tiene un medio para fijarse a un mecanismo de elevacion. En una realizacion particular, eltapon posee además un medio para introducir un gas inerte, como argon, en el bano de metal fundido durante las operaciones de colada continua. Dicho tapon decolada comprende: (a)un cuerpo alargado de material refractario que comprende (i)un orificio situado coaxialmente con respecto al cuerpo del tapon de yadaptado para recibir de forma fija una barra metálica para su fijacion a un mecanismo de elevacion, disponiendo el orificio axial del cuerpo del materialrefractario de una porcion alargada que presenta una superficie de cierre anular separada del extremo superior del cuerpo de material refractario (ii)un mediopara la fijacion de dicha barra metálica; y (b)una barra metálica alargadafijada al cuerpo de material refractario adaptada en su extremo superior para sufijacion a un mecanismo de elevacion para desplazar verticalmente el tapon; en donde dicho cuerpo de material refractario comprende al menos en parte materialrefractariorelativamente impermeable a los gases. Dicha barra metálica posee un orificio axial que comunica en su parte inferior con el orificio del cuerpo dematerial refractario y dicho cuerpo de material refractario dispone, en su extremo inferior, de un medio para introducir gas en el bano de metal fundido. Elmaterial relativamente impermeable a los gases se elige entre los materiales refractarios que incorporan aditivos capaces de reducir el diámetro medio de losporos, como agentes fundentes y/o elementos metálicos que forman carburos cuando llegan a una temperatura elevada, o bien entre materiales que incorporanagentes fundentes elegidos entre oxidos alcalinos o sílices. Dicho material relativamente impermeable a los gases tiene una permeabilidad específica menor que5 x 10-17m2.A plug for regulating the flow of a molten metal from a casting group, for example, of steel or cast iron from a distributor or of a casting spoon, and more especially, a plug in a piece having a means to be fixed to a lifting mechanism In a particular embodiment, the cap also has a means for introducing an inert gas, such as argon, into the molten metal bath during continuous casting operations. Said decorated cap comprises: (a) an elongated body of refractory material comprising (i) a hole coaxially located with respect to the body of the cap and adapted to receive a fixed metal bar for attachment to a lifting mechanism, the axial hole of the body of the refractory material of an elongated portion having an annular closure surface separated from the upper end of the body of refractory material (ii) a means for fixing said metal bar; and (b) an elongated metal bar fixed to the body of refractory material adapted at its upper end to support a lifting mechanism to move the plug vertically; wherein said body of refractory material comprises at least partly refractory material relatively impermeable to gases. Said metal bar has an axial hole that communicates in its lower part with the hole of the refractory material body and said body of refractory material has, at its lower end, a means for introducing gas into the molten metal bath. The relatively gas-impermeable material is chosen from refractory materials that incorporate additives capable of reducing the average diameter of the pores, such as melting agents and / or metal elements that form carbides when they reach a high temperature, or between materials that incorporate melting agents chosen between alkali oxides or silicas. Said material relatively impermeable to gases has a specific permeability of less than 5 x 10-17m2.
