Dispenser for synthetic slag forming material.

摘要

A dispenser (10) of material for forming a synthetic slag in a metallurgical treatment ladle includes an elongate vertically oriented housing (12) having a tapered discharge section (23) above an open lower end. A conical closure member (18) is supported for reciprocal movement into and out of a closed position relative to the discharge opening (16). The closure member (18) has a surface portion surrounding the margin of the opening (16) and having a plurality of holes (42) formed therein in a predetermined array so that the slag forming material will be evenly distributed over the surface of the molten metal. The housing (12) is mounted at the end of a boom (14) for horizontal movement to position the discharge opening (16) above the ladle of metal being treated. A filter (20) is located at the upper end of the housing (12) for removing particles from the air used to transport the material to the dispenser (10).
