摘要： A primary object of the present invention is to provide a method for continuous casting with which slabs for heavy gauge steel plate in which porosities remaining about their centers in the thickness direction are extremely decreased can be manufactured. In the present invention, when a slab that is used as a material for manufacturing heavy gauge steel plate by hot-rolling is continuously cast, two pairs of reduction rolls 7 that are arranged separately from each other with an interval between the pairs in a range from 3 m to 7 m, between which a support roll 6 is arranged, are used, reduction is carried out on a slab 8 by 3 to 15 mm with the reduction rolls 7 at the first stage under the condition where the slab includes an unsolidified portion with the solid-phase ratio of the central part of the slab in the thickness direction in a range from 0.8 to less than 1, and reduction is further carried out on the slab with the reduction rolls 7 at the second stage under the condition where the slab is completely solidified.

摘要： Provided is a method of continuous casting heterogeneous steels which includes the processes of obtaining dimensionless relative concentrations of subsequent steel to previous steel respectively at surface and inside of a continuous cast strand in real time, calculating positions in a longitudinal direction of the strand having the dimensionless relative concentrations at the surface and the inside obtained in real time, predicting a mixed portion in the strand by respectively comparing the obtained dimensionless relative concentrations of the surface and the inside with reference concentrations, and cutting off the predicted mixed portion. Thus, according to exemplary embodiments, the mixed portion is not cut to a predetermined length regardless of operating conditions during each operation of heterogeneous steels as in the related art, but the dimensionless concentrations of each of the surface and the center of the strand are obtained for each operation of heterogeneous steels, and positions of the strand having the obtained dimensionless concentrations are calculated to predict the position and the length of the mixed portion. Thus, since the accuracy of the prediction of the position and length of the mixed portion is improved, a decrease in profitability due to excessive cut-off of the mixed portion may be prevented and the shipment of defect products due to less cut-off of the mixed portion to client companies may be prevented.
