Filed: 1993-10-04
Abstract: PURPOSE:To produce a cast slab having mainly columnar crystal and a little separation by controlling molten steel temp. in a tundish and casting while giving static magnetic field in a mold. CONSTITUTION:The molten steel 7 is continuously poured in the direction of short sides 2 of the mold 3 from spouting holes 6, 6a opened in the symmetrical positions below an immersion nozzle 5 arranged at the center part of the rectangular mold 3 while holding the molten steel temp. in a tundish 4 to the temp. at higher than the solidified temp. by 20-40 deg.C. Further, the casting executed while giving the magnetic field to the molten steel 7 over the whole widths of the long sides of the mold 3 by the static magnetic field 11 arranged below the spouting holes 6, 6a in the immersion nozzle. By this method, the molten steel 7 can be held to the high temp. condition in the non-solidified part at the upper part from the magnetic field body, and the generation of equiaxed crystal is suppressed. On the other hand, the descending speed of the descending flows 13, 13a by quickly reduced by working the brake action at the position giving the magnetic field. By this method, the unidirectional columnar crystal can be produced because the molten steel stream is straightened and flowed down over the whole widths in the long side direction of the drawn cast slab 8 in the unsolidified layer 14 below the magnetic field.

Abstract: PURPOSE:To enable the detection of the deterioration in the insulating property of a plating bath, by measuring voltages and currents not only between the core metal of the plating cell and the plus side of a plating power source but also between said core metal and the minus side of said power source. CONSTITUTION:A voltage detector 8 and a current detector 10 are connected between the core metal of a plating bath and the plus side of a plating power source and a voltage detector 12 and a current detector 14 are connected between the core metal of said plating bath and the minus side of said power source. The detection values of the detectors 8, 14 are operated by an operator 15 while the detection values of the detectors 12, 10 are operated by an operator 16 to calculate insulating resistance values which are, in turn, inputted to a memory comparator 17. The comparator 17 stores the insulating resistance values at the beginning of operation and compares the same with insulating values detected at intervals of 3-5min on and after and, when the compared value reaches an abnormal value, an alarm 18 is operated. When insulating resistance is further lowered, a current blocking signal generator 19 is operated and the blocking signal blocks a power source apparatus 21 through a current controller 20. Therefore, the adhesion of a metal to the core metal of the plating bath is prevented.
