Container for molten metal, and a method for an interchangeable connection of a refractory porous plug or a refractory sleeve.

摘要

In a container for molten metal at least one opening (4, 24) is provided, in which a refractory perforated brick (5, 25) is installed. In the perforated brick opening (6, 26) a refractory purging plug (10) or a pouring opening (31) forming refractory sleeve (30) is inserted. Between the perforated brick opening (6, 26) and the sink (10) or the sleeve (30) is filled with a refractory mass defined gap (15, 35) is formed, wherein the mass consists of such a material that they are for replacement the sink (10) or the sleeve (30) can be easily drilled or milled. This eliminates not only the time-consuming cleaning work, but also the risk that the perforated brick is damaged.
