Abstract: A continuous casting installation comprises an ingot mould and an oscillating holding device used for causing the ingot mould to swing when in a casting position. The installation consists, in a separable manner, of an interchangeable part and a stationary part. To replace the intechangeable part, it is separated from the stationary one and moved using a conveying means, at least along a partial path, from its position of operation into an area beneath the casting position. This enables, especially in the multiline casting installations, the interchangeable part to be transported during the casting process and, for example, along paths comprising straight or arciform segments, to any purposefully selected position and to be replaced by a new interchangeable part to be replaced in multiline installations with no interference with the casting process in any adjacent ingot arrangement.

Abstract: In the production of grain oriented electrical steel sheet, controlling the condition of thin slab continuous casting results in advantageous solidification structures and precipitates. The steel has an initial content of carbon less than 300 ppm and an initial content of acid-soluble aluminum higher than that normally used for said type of steel. During the final processing steps, the annealed sheet is nitrided through a limited amount of nitrogen. This, in turn, renders the process for controlling the grain dimensions much less critical and results in a constant quality product.
