Abstract
A continuous steel casting system having a mold into which molten steel of different grades may be successively introduced and from which a casting continuously emerges. A grade separator device is provided that is positionable into the mold inlet opening immediately following completion of the introduction of a first grade of molten steel and before the introduction of a second grade for forming a separating barrier between the first and second grades of molten steel and for enhancing cooling and solidification at the juncture between the first and second grades of molten steel. The grade separator device comprises a plurality of elongated spaced apart steel separator plates arranged in a V configuration that permits limited flow through of the second grade of molten steel about the grade separator device and into limited intermixing relation with the first grade of molten steel for preventing the entrapment of gas bubbles about the separator device and for reducing the tendency of splattering of the second grade of molten metal when directed into the mold and onto the grade separator device.
