Abstract: A method for the sequential casting of steel strip in steel strip casting equipment wherein under normal operating conditions a steel melt is fed through a pouring tube having discharge ports into the pouring area of a cooled ingot mold at a location below the surface of the melt in the mold and is thereafter removed from the mold in the form of steel strip by the combined operation of mold oscillation means and strip discharge means. After the feed of melt is interrupted, anchoring rods are partially longitudinally immersed into the melt laterally of the pouring area of the mold, and the surface of the melt in the mold is lowered to a level below the pouring area. After a desired interval, the melt feed is continued, and the level of the surface of the melt in the mold is allowed to rise above the discharge ports of the pouring tube. Thereafter, casting flux is applied to the surface of the melt, and the operation of the mold oscillation means and the strip discharge means is resumed. The method also includes the steps of restarting the feed of melt through the pouring tube after a desired interval; allowing the level of the melt in the cavity of the mold to rise above the discharge opening of the pouring tube; thereafter applying a layer of casting flux to the surface of the melt in the mold; and restarting the strip discharge means and the mold oscillation means such that the original level of melt in the cavity in the mold is reestablished and maintained.

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: The disclosure relates to a process for continuous continuous casting in which melts of different chemical compositions are successively cast into a water-cooled mould to form a continuous bar. When casting a melt of one composition is terminated, a metallic body is inserted into the mould so that it may weld with said melt, and then casting is continued with a melt of another composition which, in turn, welds with said metallic body. By this process the formation of transitional zones comprising a mixture of melts of different chemical compositions is avoided.
