Abstract

La presente invención se refiere a aparato adaptado para su empleo en remover o interrumpir un bloqueo de una abertura de vaciado de un recipiente contenedor de metal fundido, este recipiente tiene n conducto alargado que se extiende desde la abertura de vaciado y el conducto a una salida del conducto; el aparato se caracteriza porque comprende; (a) un conducto para gas, conectable a un suministro de gas, conectable a un suministro de gas bajo presión (por ejemplo oxígeno o un gas inerte) y que se extiende dentro del conducto de metal fundido a traves de la salida del conducto, para suministrar un cilindro, el cual se asegura en el conducto y se dirige a la abertura de vaciado; y (b) un proyectil cargado en el barril y, al admitir gas bajo presión al conducto de gas, puede ser propulsado hacia la abertura de vaciado, para hacer impacto en cualquier bloqueo ahí presente.The present invention relates to apparatus adapted for use in removing or interrupting a blockage of a drain opening of a molten metal container, this container has an elongated conduit extending from the drain opening and the conduit to an outlet duct; the apparatus is characterized in that it comprises; (a) a gas conduit, connectable to a gas supply, connectable to a pressurized gas supply (eg, oxygen or an inert gas) and extending into the molten metal conduit through the conduit outlet, to supply a cylinder, which is secured in the duct and is directed to the drain opening; and (b) a projectile loaded into the barrel and, by admitting gas under pressure to the gas conduit, can be propelled into the discharge opening, to impact any blockage present there.
