Abstract
Un método para desulfurar metal caliente mediante el uso de una instalación de desulfuración por agitación mecánica que incluye agregar una porción de un agente desulfurante con base de cal, necesaria para desulfurar metal caliente sobre una superficie de baño del metal caliente, al eyectar la porción del agente desulfurante con base de cal a través de una lanza superior, junto con un gas portador -al tiempo que se agita el metal caliente con un propulsor- y agregar el resto del agente desulfurante con base de cal desde arriba, sobre la superficie de baño del metal caliente. La velocidad de las partículas (C: kg/m2) del agente desulfurante con base de cal agregado mediante eyección a través de la lanza superior ante la colisión con la superficie de baño de metal caliente, se controla de manera tal que sea superior o igual a una velocidad de partículas crítica calculada mediante la siguiente ecuación: C = -0,000093 x R2 + 0,047 x R + 17, de acuerdo con la cantidad (R: kg/m2) del agente desulfurante con base de cal agregado desde arriba.A method for desulfurizing hot metal by using a desulphurization facility by mechanical agitation that includes adding a portion of a lime-based desulfurizing agent, necessary to desulfurize hot metal on a bath surface of the hot metal, by ejecting the portion of the lime-based desulfurizing agent through an upper lance, together with a carrier gas - while stirring the hot metal with a propellant - and adding the rest of the lime-based desulphurizing agent from above, on the bath surface of hot metal. The particle velocity (C: kg / m2) of the lime-based desulfurizing agent added by ejection through the upper lance before the collision with the hot metal bath surface, is controlled in such a way that it is greater than or equal to at a critical particle rate calculated by the following equation: C = -0.000093 x R2 + 0.047 x R + 17, according to the amount (R: kg / m2) of the lime-based desulfurizing agent added from above.
