摘要： PURPOSE:To cast a slab having a large section and good quality by providing electromagnetic stirrers which stir the unsolidified part in a slab descending from a casting mold and stirring said part at the height at which the residual molten steel rate attains an optimum value. CONSTITUTION:The molten steel is poured from a tundish into the casting mold 2 and a dummy bar 3 is fixed to right under the mold 2 to wait for the solidification of the molten steel. The dummy bar 3 is lowered and support rolls 5, 6 are driven and rotated by the slab 1 to support the slab 1 from both sides when the residual molten steel rate in the mold 2 attains about 30%. The in-roll electromagnetic stirrer 5a incorporated into each support roll 5 is started to stir the unsolidified part 1a in the slab 1 at the same instant when the bar 3 starts descending. All of the stirrers 5a are not simultaneously driven but only the stirrers 5a occupying the optimum stirring position are selectively driven according to the descending of the slab 1 in this case.

摘要： PURPOSE:To reduce the irregularity in the segregation of the product by using a rolling reduction roll of division type where the effective rolling reduction roll part and the bearing box part are alternately arranged in the width direction of the cast slab as the roll for executing the rolling reduction of the cast slab in the final process of solidification to realize the cooling control where the surface temperature of the cast slab is in the prescribed temperature range. CONSTITUTION:The continuous casting of the steel slab is executed, and the cast stab 1 in the final process of drawing where the non-solidified part is present in the center of the cast slab is rolled down by a rolling reduction roll for the cast slab in the final process of solidification. The cast slab is rolled down by using rolling reduction rolls 2, 3 of division type where an effective rolling reduction roll part 4 and a bearing box part 5 are alternately arranged in the width direction of the cast slab as the rolling reduction roll. The cooling control is realized so that the surface temperature of the cast slab may be 500-600 deg.C in the area of rolling reduction, and at the same time, this rolling reduction is executed in the area where the center solid phase ratio is over the solid phase ratio at the critical flowability. This constitution reduces the irregularity of the center segregation generated in the center of the cast slab to the level where there is no problem in the product stage.

摘要： PURPOSE:To measure the surface temperature of the moving casting slab securely, accurately, stably, and continuously by passing a couple of sheath jacket constitution wires between the casting slab and a roll while they are separated from each other. CONSTITUTION:The couple of sheath jacket constitution wires 130 and 140 are separated from each other in the axial direction of the roll R by passing through individual guide holes 210 and 220, and pass the roll R without crossing each other. Thus, the surface temperature of the casting slab is measured continuously by a thermocouple which moves by being fed as the casting slab G moves. As a matter of course, the casting slab surface temperature is securely and accurately measured from a temperature contact positioned in a metallic piece 120 embedded in the surface of the casting slab G. Specially, the constitution lines 130 and 140 are prevented from being superposed on each other or crossing each other. Therefore, thermocouple element wires are prevented from contacting each other to cause a short circuit or being broken, and the casting slab surface temperature can be measured continuously.
