VESSEL FOR MOLTEN METAL HAVING TRANSVERSELY LONG MECHANISM FOR BLOWING GAS

摘要

PURPOSE:To provide a titled vessel into which a substantial amt. of gas can be uniformly supplied with a simple operation by constituting a titled mechanism in such a way that a gas blow hole, a transversely long communicating hole and the transversely long porous plug attached to a sliding plate brick are matched and the gas is blown into the vessel. CONSTITUTION:A stationary plate brick 3 is fixed to the wall body part around a blow hole 2 penetrating through the wall body of a vessel 1 for contg. a molten metal and a transversely long communicating hole 4 is punched therein. A sliding plate brick 5 is provided freely slidably in the direction intersecting the hole 4 is provided on the brick 3 and a face pressure is generated to the brick 3 by a pressing plate 9 provided with spring elements. A transversely long porous plug 7 is mounted into the small hole 6 punched to the brick 5 and is matched with the hole 4 by the shortest stroke of the brick 5, by which the gas introduced from a common pipe 8 is substantially and uniformly supplied into the vessel 1.
