摘要：In a continuous casting process for steel, a molten core inside a strand is stalledat a specific point Q in a pass line of the strand to form a cored portion including nomolten steel in the strand downstream of the specific point Q, and the cored portion isrolled by a pair of rolls under pressing into a solid strand in the latter half of a stranddrawing stroke. The resulting solid strand comprises a skin formed of a chill crystal andthe interior formed of a columnar crystal by addition of proper casting temperature. Athrough continuous casting/rolling process in which the above improved continuouscasting process is combined with a subsequent hot rolling process is also disclosed. Adrastic increase in the casting efficiency, an improvement in quality, and an equipmentcapable of freely adjusting a casting thickness can be resulted so that direct couplingbetween continuous casting and rolling is achieved and near-net-shaping of various steelmaterials is promoted.
