摘要： PURPOSE:To improve inferior brushing with a brush roll in a continuous casting apparatus using drum type casting roll. CONSTITUTION:The brush roll 20 for grinding the casting roll in the continuous casting apparatus, which pushes by parallel supporting the shaft, is formed to the drum type matched to the peripheral surface shape of the casting roll at the time of stationarily driving. By this method, as the biting rate of the casting roll to the brush roll 20 is uniformized to over the whole width in the axial direction of the casting roll and the brush roll 20, by setting the biting rate to the suitable value, favorable brushing is executed to over the whole width of the casting drum. Stuck material on the roll surface is removed in every place or even in the case of remaining some stuck material, the stuck material is uniformly remained without remaining unevenness, and it is prevented to develop the defect of traverse cracking, etc., on the cast strip continuously cast.

摘要： PURPOSE:To secure good uniformity in the thickness of a cast slab in a trans verse direction by shifting a pouring nozzle in the transverse direction of the cast slab so as to eliminate the difference between the thicknesses at both side end parts of the case slab during casting. CONSTITUTION:A controller 13 fetches the thickness data (i), (j) detected with sensors 12a, 12b, and based on the data, control signals (k), (l) are sent to the molten metal pressing devices 11a and 11b in a pouring nozzle shifting device 11, respectively and by this working, the shifting of a tundish 10 and a pouring nozzle 4 are controlled. Then the molten steel temp. at the thin slab thickness side is higher than the molten steel temp. at the thick slab thickness side. The controller 13 issues the command for shifting a pouring nozzle 4 toward the thick side of slab thickness to the shifting device 11 so as to eliminate temp. difference between then and the shifting device 11 shifts the pouring nozzle 4 to lower position of the molten steel temp. in a pouring basin 6 by driving a hydraulic device receiving the command. Thus, the cast slab 8 having substantially the same slab thickness at both side edge parts is cast.

摘要： PURPOSE:To make waiting time for heating unnecessary at the time of changing side weirs and to automate the changing of the side weirs by removing both side weirs slready used, carrying one pair of new side weirs waited while heating with a heating device so as to face to both end surfaces of a cooling drum and setting. CONSTITUTION:One pair of the side weirs 52 which are heated in the heating device 21 on kept in standby are held by a clamping device and swung on a shifting path by a swinging means 1. Then one pair of the side weirs 52 are shifted to the upper part of the setting position by a shifting means 2, and descended by a lifting means 4 so as to join with both end surfaces of both cooling drums 51 and set. Then molten metal is poured into a pouring basin part formed with the cooling drums 51 and the side weirs 52 after shifting clamping device by a shifting means 2, to start continuous casting for cast strip. When the side weirs 52, are worn the continuous casting is stopped and these side weirs 52 are removed from the setting position by reverse order and descended to near the shifting path and changed with the side weirs 52 heated by the heating device 21.
