Abstract

PURPOSE: To make the S values of the molten iron after a desulfurization treatment and after delivery from a torpede car practically equal by providing bubbling plugs which stir the molten iron to the bottom of the body in the end part of the torpedo car.
CONSTITUTION: The molten iron 2 contained in a contg. body 1 is stirred like arrows α by the carrier gas such as Ar blown through an immersion lance 3, but the stirring near both ends of the body 1 is insufficient. Thereupon, a gas such as Ar is blown from pipings 6 through the bubbling plugs 5 provided near both end pats of the body 1. Thereby, the dead zones of desulfurization are eliminated, and the S values of the molten iron are made equal over before and after delivery. Each plug 5 is constituted of fine tubes 9 which branceh the leaking flow of the molten iron produced when porous bricks 8 as main parts facing the molten iron break into fine flows to form solidified clogging flow and refractory bricks 10.
