Abstract: In melting and casting by a water-cooled crucible induction melting technique, a partition means is inserted on top portion of a melt, and a new raw material for is charged on an upper side of the partition means to continue the melting and casting. Therefore, the continuous casting can be kept while avoiding mixture of the melt on a lower side of with the melt on an upper side of the partition means. A partition plate or a partition plate with legs can be used as the partition means. When the present invention is applied to production of a silicon ingot used for a solar cell and the like, productivity is largely improved, which allows costs to be remarkably reduced in solar energy generation. Therefore, the present invention can widely be utilized as the method for casting a polycrystalline-silicon ingot for a solar cell.

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.

Abstract: The cross section of a cast strand formed in a continuous casting mold, which has at least one shiftable wall, is changed by stopping the pouring of metal into one end of the mold and the withdrawal of a partially solidified strand from the other and allowing the strand and end portion remaining in the mold to cool enough to be self-supporting. An insert having its upper portion corresponding to the new cross-sectional area desired for the strand, and having its bottom portion conforming to the area of the original strand, is placed on the aforesaid strand end portion. If the new cross section is to be larger, the shiftable mold wall, or walls, are moved outward to receive an appropriate insert and to correspond to the new size defined by the upper portion of the insert. If the new cross section is to be smaller, an appropriate insert is placed on the strand end portion in the mold and sufficient metal is poured into the mold to partially fill the interior of the insert; then, when this additional metal has solidified enough to be self-supporting the strand is withdrawn slightly from mold and the shiftable wall, or walls, are moved inward against the upper portion of the insert to define the new strand size.
