ABSTRACT:
In a continuous casting process for steel, a molten core inside a strand is stalled at a specific point Q in a pass line of the strand to form a cored portion including no molten steel in the strand downstream of the specific point Q, and the cored portion is rolled by a pair of rolls under pressing into a solid strand in the latter half of a strand drawing stroke. The resulting solid strand comprises a skin formed of a chill crystal and the interior formed of a columnar crystal by addition of proper casting temperature. A through continuous casting/rolling process in which the above improved continuous casting process is combined with a subsequent hot rolling process is also disclosed. A drastic increase in the casting efficiency, an improvement in quality, and an equipment capable of freely adjusting a casting thickness can be resulted so that direct coupling between continuous casting and rolling is achieved and near-net-shaping of various steel materials is promoted.
